FACTORS INFLUENCING THE DECISION TO ADOPT BLOCKCHAIN-BASED
CRYPTOCURRENCIES USING TECHNOLOGY ACCEPTANCE MODEL
Introduction
Overview
The study examined the factors influencing the decision to adopt Blockchain-based
cryptocurrencies in the United States. Blockchain technology is one of the most hyped
decentralized innovations with a bright future (Khan et al., 2021). Cryptocurrencies are not the
only application of blockchain technology, but in this dissertation, the researcher focused on
cryptocurrencies. Cryptocurrency can be described as digital money secured with the
cryptographic methods used to store and transfer value among the participants in the blockchain
network (Antonopoulos, 2014; Vasin, 2018). The first commercial transaction using
Cryptocurrency-Bitcoin was recorded in 2010 when a programmer used 10,000 Bitcoin to buy
two pizzas (Extance, 2015). The number of Bitcoin transactions is increasing daily, as is the
number of businesses accepting cryptocurrencies (Churilov, 2015). The World Economic Forum
(2015) survey showed that blockchain will be rising to 10% of the global GDP by 2027 (Khan et
al., 2021).
The cryptocurrency market showed remarkable growth throughout 2017 (Vasin, 2018). At
the beginning of 2017, the total market cap of cryptocurrencies was 17.7 billion US dollars; at
the end of the year, it skyrocketed to 592 billion US dollars, more than 30 times than the
beginning of the year (Vasin, 2018). As of March 2022, there are more than 18,000
cryptocurrencies, and their total market cap is more than US 2 trillion US dollars, according to a
well-known cryptocurrency analysis platform, CoinMarketCap.com. The price of
cryptocurrencies and high volatility concern consumers and policymakers (J. Liu & Serletis,
2019). Blockchain has revolutionized and internationalized the funding process and allowed the
trading of tokens (Boreiko & Sahdev, 2018). Initial Coin Offerings (ICOs) have completely
changed the procedure of borrowing and investing money by allowing anyone worldwide to
invest in any startup established by team members residing in different countries (Boreiko &
Sahdev, 2018).
The following research study aims to examine blockchain-based cryptocurrency
rigorously. The blockchain is the distributed ledger and the backbone technology of
cryptocurrencies (Schatsky & Muraskin, 2015). A blockchain is a digital, distributed transaction
ledger with identical copies on multiple computing nodes maintained by various entities
(Schatsky & Muraskin, 2015). It all started when Satoshi Nakamoto, the pseudonymous
blockchain developer, published a white paper titled “Bitcoin: A peer-to-peer electronic cash
system” in 2008 (Nakamoto, 2008). Satoshi Nakamoto proposed a peer-to-peer network that uses
a decentralized proof-of-work concept to log all transactions and solve double-spending issues;
since then, thousands of cryptocurrencies and tokens have been created based on blockchain
technology (Hellani et al., 2018; Schatsky & Muraskin, 2015).
Bitcoin was the first cryptocurrency based on the blockchain, but it has yet to be used
daily for payments because of the longer block creation time (Vasin, 2018). Arias-Oliva et al.
(2019) mentioned that Blockchain-based cryptocurrencies would transform our transaction
method, just like the Internet revolutionized the communication system. As an emerging financial
technology, cryptocurrencies provide many opportunities but have significant challenges and
limitations (Arias-Oliva et al., 2019). Chapter One contains the background problem and the
purpose of the research. Furthermore, Chapter One discusses the methodology and the theoretical
framework used in this quantitative correlation research for examining the factors affecting the
adoption of Blockchain-based cryptocurrencies in the United States. The limitations and
assumptions of the study are mentioned, followed by the definitions in chapter one.
Background and Problem Statement
The research problem derives from a gap in the literature, conflict in the research results
in the literature that have been ignored in the literature, requires raising a concern of
marginalized participants, and real-life problems found in the workplace, the home, or the
community (Creswell & Creswell, 2018). Blockchain technology is one of the most exciting,
decentralized revolutions, believing in a bright future (Khan et al., 2021). An initial concept of
blockchain technology was introduced in research by Haber and Stornetta (1990). Later,
Blockchain captured more attention when Satoshi Nakamoto (2008) published his research paper
Bitcoin: A peer-to-peer electronic cash system. Bitcoin’s growth and dramatic rise in price in
2017 are causing financial institutions like the Wall Street Journal to take notice, while
wellknown publications like Fortune and The Economist have issued cautionary warnings about
cryptocurrencies (Madey, 2017; Stavros, 2017).
McCorry (2018) mentioned that Bitcoin was introduced in the aftermath of the worst
financial crisis since the Great Depression in the 1930s, which led to subsequent bailouts for both
banks and governments. Nakamoto posted the Bitcoin whitepaper in November 2008, and the
source code was published alongside connection instructions for the Bitcoin network in January
2009 (McCorry, 2018). Today, if an individual in Japan wants to transfer money to someone
living in the United States through conventional currencies, they may have to use trusted
thirdparty services like banking applications, PayPal, Cash App, etc. (Madey, 2017). These
trusted third-party services charge a high transaction fee to transfer money reliably, and it may
take a long time, even a few days, to complete the transfer process (Madey, 2017). As blockchain
is a decentralized technology, a person can transfer money confidentially without the
involvement of any third-party services that eliminate the transaction fee from the third party,
reducing the overall transaction cost, and the cross-border transaction procedure takes less time
than the conventional method (J. H. Lee, 2019; Madey, 2017).
Blockchain provides vital characteristics of decentralization, persistency, anonymity,
auditability, and immutability (Zheng et al., 2018). Blockchain technology attempts to solve
existing problems of transferring money via the conventional method (Madey, 2017). There are
some technical challenges and limitations like low throughput, higher latency, smaller block size,
and bandwidth, its usage in illegal activities, tax evasion, and money laundering, some security
concerns like 51% attack, high energy usage in the mining process, limited usability to existing
API, versioning, and forking issues (Yli-Huumo et al., 2016). Among the many hindrances to
Blockchain-based cryptocurrencies, scalability is one of the critical issues in implementing
public blockchains (Khan et al., 2021). Khan et al. (2021) stated that more literature resources
are needed for scalability issues. Public blockchain scalability is a growing concern and is
becoming a focus of research topics across the industry, where many sectors are trying to adopt
the blockchain in their respective applications (Khan et al., 2021). The scalability issue is present
in major public blockchain applications because all nodes must record and execute a
computational calculation to validate the transactions (Khan et al., 2021). Public blockchains
always demand high bandwidth network connectivity, massive storage space, and considerable
computation power, which eventually requires more electricity (Khan et al., 2021).
Silva and Mira da Silva (2022) compared blockchain technology with the internet of the
1990s regarding innovation. Cryptocurrencies’ unregulated characteristics are skeptical to many
people, while some believe that they are the future and investing in them is an excellent
opportunity (Piedade, 2018). Decentralized Finance (DeFi) is also being discussed by various
stakeholders of the financial market; it utilizes cryptocurrency and blockchain technology to
govern financial transactions with aims to democratize finance by replacing centralized legacy
organizations with peer-to-peer network systems that can provide a wide range of financial
services (Silva & Mira da Silva, 2022). Silva and Mira da Silva (2022) recognized that
cryptocurrency adoption and transaction volumes are the factors that threaten the market and
price stability.
The scalability trilemma described by Vitalik Buterin, the co-founder of Ethereum, is
well-known in blockchain (Hafid et al., 2020). It is first described by the co-founder of
Ethereum, Vitalik Buterin (Yuan & Wang, 2018). According to Vitalik, tradeoffs between three
properties, 1) decentralization, 2) scalability, and 3) Security, are inevitable. Decentralization is
the core and nature of blockchain technology; scalability is the main challenge, whereas security
is an essential blockchain property (Hafid et al., 2020). It is crucial to find the right balance
among all three aspects, decentralization, scalability, and security of the blockchain, as the
scalability trilemma states that a blockchain solution can only have two out of either
decentralization, scalability, or security (Khan et al., 2021). Hafid et al. (2020) and Khan et al.
(2021) presented several solutions to the scalability issue, but they all came with challenges.
Khan et al. (2021) found that scalability has several factors like transaction throughput,
the number of nodes, storage, block size, high communication, latency, cost, and verification
process attached to it. Transaction throughput and transaction latency are among the most
discussed factors in blockchain technology. Most of these factors are interdependent and linked
directly or indirectly to a consensus mechanism (Khan et al., 2021). Poon and Dryja (2016)
revealed that the payment network Visa achieved 47,000 transactions per second (TPS) on its
network, whereas Bitcoin supports less than seven transactions per second with a 1-megabyte
block limit.
Hafid et al. (2020) and Khan et al. (2021) revealed that blockchain scalability is emerging
as a challenging issue. Despite the characteristics like transparency, decentralization,
immutability, and fully distributed peer-to-peer architecture to record digital assets, one of the
critical limitations of blockchain is scalability (Hafid et al., 2020; Khan et al., 2021; Kumar
Bhardwaj et al., 2021); Swan, 2017). Hafid et al. (2020) revealed that scalability needs to be
better defined in the literature. Kamble et al. (2021) demonstrated that scalability is a significant
source of complexity in a blockchain system. Kamble et al. (2021) mentioned that companies
should verify compatibility while deciding to implement blockchain and distributed ledger
technology and whether these various financial services products and services meet regulatory
requirements. Swan (2017) revealed that the development of consensus algorithms that are
scalable, efficient, and secure is a challenge for the long-term development of blockchain
technology.
Silva and Mira da Silva (2022) observed the research gap in cryptocurrency adoption and
called for further research. Furthermore, Silva and Mira da Silva (2022) added that the
implication of blockchain technologies requires in-depth multi-disciplinary attention from the
academic, scientific, and policy-making levels for implementing and adopting blockchain in
public service, central banks, and government institutions. Ghonimy (2021) studied the influence
of four constructs: perceived privacy, perceived institutional trust, perceived usefulness, and
perceived ease of use on adopting blockchain technology and recommended further investigating
constructs like social influence and compatibility. Grover et al. (2019) suggested more research
to understand the perceived usefulness and perceived ease of use for blockchain technology
applications. Conrad (2009) mentioned a research analysis gap in how information technology
innovations are productively adopted at the individual level and in identifying the critical success
factors affecting attitudes toward these new technologies. Wokke and Rodenrijs (2018)
mentioned that the relationship between social influence, perceived usefulness, and perceived
ease of use is not explored because of errors, so they suggested exploring their relationship in
future studies.
Yeoh (2017) revealed that blockchain technology is a relatively new innovation that must
overcome critical hurdles for broad adoption in the financial services sector. Ghonimy (2021) and
Yeoh (2017) mentioned that the adoption of blockchain technology has been growing
considerably over recent years, so it is indispensable to investigate the factors influencing the
decision to adopt it. Owusu (2022) mentioned that the lack of adequate knowledge about the
impact of cryptocurrency adoption would make investors prone to cyber thefts and financial
losses linked to the crypto market volatility. Owusu (2022) called for academic work and
research on factors affecting cryptocurrency adoption in the United States as the merits and
demerits of cryptocurrency adoption by the corporate world, financial, and individuals are
unknown. More scholarly literature is required to describe the factors affecting the adoption of
blockchain-based cryptocurrencies in the United States (Ramirez, 2022). The specific problem is
that with the ever-increasing adoption of Blockchain technology, user-level adoption of
cryptocurrencies in the United States is only a few percentages of that of existing financial
transaction methods; researching factors affecting the adoption of cryptocurrency will add to the
pool of scholarly knowledge and assist stakeholders in identifying factors that influence the
adoption of the technology (Ghonimy, 2021).
Purpose of the Study
The purpose of this non-experimental quantitative correlational study was to examine the
variables, Perceived Usefulness (PU), Perceived Ease-of-Use (PEOU), Compatibility (COMPB),
Complexity (COMPX), and Social Influence (SI), which influence the adoption of
Blockchainbased cryptocurrencies. Ghonimy (2021) mentioned that studying the factors that
influence the decision to adopt Blockchain technology could give companies in the United States
an advantage in predicting the growth of new technologies in the future. In contrast,
organizations could lose a competitive edge over their competitors overseas if organizations in
the United States failed to adopt Blockchain technology. In this research, Perceived Usefulness
(PU), Perceived Ease-ofUse (PEOU), Compatibility (COMPB), Complexity (COMPX), and
Social Influence (SI) were the independent variables. In contrast, the Intention to Use (IU)
cryptocurrencies is the dependent variable. The purpose statement is the most critical in the entire
research study and needs to be clearly and specifically presented for the respective study. The
purpose statement contains a study's objectives, intent, or main idea (Creswell & Creswell,
2018). According to Locke et al. (2007), the purpose statement shows “Why you want to do the
study and what you intend to accomplish” (p. 9). The online survey using the SurveyMonkey tool
was conducted to collect the data of participants residing in the United States. The
SurveyMonkey Target
Audience service was used to recruit the participants, and 141 valid responses were received. The
multiple regression analysis was applied to determine the extent to which the technology
acceptance constructs predict intention to adopt cryptocurrencies.
Significance of the Study
This quantitative study tests the factors influencing the decision to adopt blockchainbased
cryptocurrencies in the United States, which would assist organizations and stakeholders in
making decisions about adopting the technology. The study examined Blockchain’s financial
application cryptocurrency, including potential benefits and challenges. This study provided
organizations and technology enthusiasts with an understanding of different factors influencing
blockchain-based cryptocurrency adoption. This study conveyed the importance of implementing
cryptocurrencies to resolve the issues present in the current conventional transaction methods.
Blockchain enthusiasts, decentralized autonomous organizations (DAOs), and policymakers will
benefit from this dissertation.
Blockchain technology has emerged as a potentially disruptive, general-purpose
technology for governments and companies to support information exchange and transactions
that require authentication and trust (Ølnes et al., 2017). Wokke and Rodenrijs (2018) observed
that there was a lack of knowledge, interest, and affinity about the cryptocurrency topic, which
indicated that cryptocurrency did not reach the mainstream market in terms of acceptance,
although cryptocurrency has received a lot of attention. By reducing the knowledge gap, there
will be a better opportunity to understand the need to classify cryptocurrency (Durr, 2021).
Blockchain technology can benefit the government and society and assist in developing
egovernment as it enables reduced costs and complexity, shared trusted processes, improved
discoverability of audit trials, and ensured trusted record-keeping (Ølnes et al., 2017). The study
will be helpful to financial investors and other individuals willing to invest in the crypto market
to expand their knowledge. The research for identifying the factors influencing cryptocurrencies
is supported by surveying participants from various fields and education levels. The result of this
study contributes to this research’s goal, providing information about customers’ behavioral
intentions toward adopting cryptocurrencies.
Research Questions
The research questions are designed to study the potential influence of Perceived
Usefulness (PU), Perceived Ease of Use (PEOU), Compatibility (COMPB), Complexity
(COMPX), and Social Influence (SI) on the decision to adopt blockchain-based cryptocurrencies.
PU, PEOU, COMPB, COMPX, and SI are independent variables, while Intention to Use (IU)
blockchain-based cryptocurrencies are dependent variables. This research determines the main
contributing factor to the use of blockchain-based cryptocurrencies and the elements that hinder
the use of cryptocurrencies.
The research was designed to illustrate relationships among the research variables in the
literature review analysis based on the theories related to the technology. The theoretical
framework and literature review section detail these research variables. The following
hypotheses were developed and tested to demonstrate a connection between these research
variables: The research questions for the study guided the discovery of what technology
acceptance factors influence the use of cryptocurrencies in the United States of America. The
research sought the answers to the following research questions after the completion of this

Theoretical Framework
The researcher used the technology acceptance model for this dissertation. The
technology acceptance model (TAM) was initially developed by Davis, F. D. (1985). It is an
information systems theory that forms the decision-making procedures resulting in users may or
may not adopt and implement a given new study or technology. The technology acceptance
model (TAM) consists of variables like perceived usefulness, ease of use, attitude toward using
technology, behavioral intention, and the fully mediated effect of system design features on
usage (Davis, 1993). The system's characteristics appear to influence behaviors via these
variables and have no additional direct effect on use (Davis, 1993).

models” by Davis, F. D., Bagozzi, R. P., & Warshaw, P. R. (1989), Management science, 35(8), p.
985. Copyright 1989 by the authors.
The Technology Acceptance Model (TAM; Davis, 1989) will remain the most used
research model as new technologies evolve (Horton et al., 2001; Venkatesh et al., 2007). TAM is
one of the most influential and widely used theoretical frameworks for information systems
(Holden & Karsh, 2010; Y. Lee et al., 2003; L. Li, 2010). Ghonimy (2021) used the extended
technology acceptance model to analyze the factors influencing the decision to adopt blockchain
technology, including perceived usefulness, perceived ease of use, perceived institutional trust,
perceived usefulness, and perceived privacy. The technology acceptance model is one of the
most used frameworks for discovering early user acceptance. The original scale measures the
TAM constructs within the context of different technologies across populations and is
sufficiently validated (Davis & Venkatesh, 1996).
The researcher planned to use the theoretical framework of technology acceptance to test
how different variables impact the intention to use cryptocurrencies. Venkatesh et al. (2003)
proposed The Unified Theory of Acceptance and Use of Technology (UTAUT) to validate a new
information technology-related theory. Later, Venkatesh et al. (2012) introduced its extension,
UTAUT2. Both models assist in validating the idea of how people and organizations adopt the
latest technology. Both models are established on Technology Acceptance Models. UTAUT
model guides determining intention to use depending on performance expectancy, effort
expectancy, social influence, and facilitating conditions of the latest technology (Venkatesh et al.,
2003).
Arias-Oliva et al. (2019) proposed technology acceptance, perceived risk, and financial
literacy to use the cryptocurrency model to test how different variables influence the choice to
use cryptocurrency from a consumer-behavior perspective. Arias-Oliva et al. (2019) applied that
model in Spain and conducted the research with college-educated adults with basic knowledge of
the internet. The researcher plans to adopt the same model to analyze how these variables
influence the intention to use cryptocurrency in the United States of America with adult
individuals with basic knowledge about blockchain-based cryptocurrencies. Ghonimy (2021)
observed that most studies used the UTAUT theory. The study was tested to add to the
knowledge about TAM theory. The researcher used an extended technology acceptance model
theory by adding one more variable of perceived barriers.
The technology acceptance model has been considered the most efficient and accurate
model to evaluate the organizational view of technology adoption. Its integration with other
models has been widely regarded as a valid method of empirical and theory-based research
studies (Palos-Sanchez et al., 2017). The TAM model’s simple and efficient design facilitates
researchers' ability to predict the wide range of individuals’ perceptions about technology
adaptation at the organizational and user levels (Carr et al., 2010). Davis (1993) stated that it is
critical to identify an early indication of user acceptance when huge financial implications are
associated with new emerging technologies. The technology acceptance model’s most common
application is to determine the relationship between perceived usefulness (PU), perceived ease of
use (PEOU), and the anticipated future usage of emerging technologies (Horton et al., 2001). The
reliability of the items of the TAM constructs measured using Cronbach’s alpha has been
calculated to exceed 0.9 across the number of studies (Davis & Venkatesh, 1996; Yousafzai et al.,
2007).
The Technology, Organization, and Environment (TOE) framework considers technology,
organization, and environmental factors that influence the adoption of emerging technology at
the institutional level (Alshamaila et al., 2013). The technological aspect of technology adoption
includes technical characteristics such as infrastructure, quality, and integration. The
organizational structure, decision-making capabilities, and management support are the
organizational factors of technology adoption. The environmental aspect of technology adoption
contains factors like supplier support, competitive pressure, and government regulations. The
TOE is one of the most robust and widely used technology adoption models in the information
systems literature compared to TAM, TRA, TPB, and IDT, which are mainly focused on
analyzing the technology adoption at the individual user’s level rather than at the organizational
level (Awa & Ojiabo, 2016; Gangwar et al., 2015).
Conrad (2009) used a conceptual hybrid model combining attributes from the diffusion of
innovations theory and the technology acceptance model to test the intention to use new
technology. Conrad (2009) revealed that although two primary theories, Rogers’s Diffusion of
Innovations and Davis’s Technology Acceptance Model, are widely cited in the literature review,
combining the organizational literature and the individual-level data gathered in the study result
in a better understanding of two vital factors, why information technology innovations succeed or
fail, and what steps may be taken to ensure success. Hebron (2008) recommended using TAM,
UTAUT, and DOI instruments to test the adoption of new IT technology at the user level.
McConnell (2009) mentioned that many researchers used the original TAM as a framework in
designing and expanding the model to include external and internal factors to test technology
adoption. Hence, the researcher proposed a conceptual model that extends TAM by adding
compatibility, complexity, and social influence variables. This dissertation aimed to add to the
knowledge about TAM theory, as most of the literature studies utilized UTAUT.

Limitations of the Study
All the participants were from the USA. Population filtration is needed as there’s an age
limit (age > = 18) to trade cryptocurrencies on financial platforms. There are more than 18000
cryptocurrencies and around 460 trading platforms according to the well-known cryptocurrency
analysis website CoinMarketCap.com (as of March 6th, 2022); only a few are being examined
during this dissertation. As any geological area does not bind blockchain technology, wherever
required, the researcher has used the rules and regulations of the USA for analysis. The results of
this dissertation are time and context-dependent. At any point in the future, the technical, social,
financial, and law and regulation factors may not be in the same state as at the time of this
dissertation. This model is designed regarding cryptocurrency, which could limit its usability to
other sectors. The study is limited to the general population of the United States over 18 who
have a fundamental knowledge of blockchain technology. The small sample size is one of the
study's limitations, which is not generalizable to any other population. The research result may
not apply to a country other than the USA. The researcher used the third-party survey platform
SurveyMonkey for an online survey. No identifiable data was collected during the procedure to
ensure the anonymity of the participants, which may introduce response bias as some participants
may submit multiple responses. To participate in an online survey, the participants must have
basic knowledge of cryptocurrencies. However, it is also essential to note that the knowledge and
perception of the technology may vary widely.
Assumptions
The first assumption was that the participants receiving an online survey were
comfortable using SurveyMonkey's web-based tool. The second assumption was that the
participants read, understood, and answered all the online survey questions honestly. Also, the
participants responded honestly to filtration questions. The third assumption was that all
participants voluntarily participated in an online survey and did not receive gifts apart from a pre-
defined small incentive to participate. The fourth assumption was that the participant's sample
size represented the population. The theoretical instrument-related assumption was that the
technology acceptance model's validity, reliability, and robustness were correct (Venkatesh &
Davis, 2000). This dissertation is about a rapidly changing cryptocurrency study; the information
available may vary. Every cryptocurrency is different, containing its characteristics, advantages,
and disadvantages. The researcher has analyzed only a few top cryptocurrencies in this research
study.
Definitions
The following terms and definitions were essential to understanding and following the
research in this study. It was crucial to establish a common ground of understanding regarding
key concepts to navigate the complexities of the investigation effectively. This section provides
concise and accurate explanations of the fundamental terms that underpin the study's framework,
enabling readers to engage with the research and its findings with clarity and comprehension.
Address: It consists of a string of letters and numbers. In the conventional method, just like a
sender needs the receiver’s account number to send a cryptocurrency, a sender needs the address
of a receiver (Antonopoulos, 2014).
Bitcoin: It is the name of the currency unit based on blockchain technology (Antonopoulos,
2014).
Block: A grouping of transactions noted with a corresponding timestamp and a fingerprint of the
previous block (Antonopoulos, 2014).
Blockchain: Blockchain is a list of validated blocks linking to its predecessor all the way to the
genesis block (Antonopoulos, 2014).
Consensus: When several nodes, usually most nodes on the network, all have the same blocks in
their locally validated best blockchain (Antonopoulos, 2014).
DAO: Decentralized Autonomous Organization. A company or an organization operates without
hierarchical management (Antonopoulos & Wood, 2018).
Double Spending: Double spending is the result of successfully spending some money more than
once. Bitcoin protects against double spending by verifying each transaction added to the
blockchain to ensure that the transaction's inputs have not already been spent (Antonopoulos,
2014).
Fee: The transaction sender usually charges a small amount to the network as a fee for processing
the requested transaction (Antonopoulos, 2014).
Genesis block: The first block in the blockchain is used to initialize the cryptocurrency
(Antonopoulos, 2014).
Hash: A digital fingerprint of some binary input (Antonopoulos, 2014).
ICO: An Initial Coin Offering is a crowd-funding mechanism companies and organizations use to
raise money by selling tokens (Antonopoulos & Wood, 2018).
Miner: A network node finds valid proof of work for new blocks by repeated hashing
(Antonopoulos, 2014).
Network: A peer-to-peer network that propagates transactions and blocks to every Bitcoin node
on the network (Antonopoulos, 2014).
Node: A software client that participates in the network (Antonopoulos & Wood, 2018).
Private Key: The secret number that allows users to prove ownership of an account or contract
by producing a digital signature. It is also known as a Secret Key (Antonopoulos & Wood, 2018).
Proof of Stack: It is a method by which cryptocurrency blockchain network targets to achieve
distributed consensus (Antonopoulos, 2014).
Proof of Work: A piece of data requiring significant computation. For example, Bitcoin miners
must find a mathematical solution to the SHA256 algorithm that meets the difficulty target across
the network (Antonopoulos, 2014).
Public Key: A number derived using a one-way function from the private key, which anyone can
share publicly and use to verify a digital signature made with the corresponding private key
(Antonopoulos & Wood, 2018).
Reward: An amount is included in each new block for the miner who found the Proof-of-Work
solution as a reward by the network (Antonopoulos, 2014).
SHA: The Secure Hash Algorithm (SHA) is a group of cryptographic hash functions developed
by the National Institute of Standards and Technology (Antonopoulos, 2014).
Sharding: It is a technique where the nodes are broken into several chunks called shards. Each
shard possesses a small part of the nodes and is responsible for processing small portions of a
transaction (Khan et al., 2021).
Tokens: Tokens are a medium of exchange granting rights to use future services of a realized
project and, as such, represent claims whose value is connected to the ultimate success of the
issuing start-up (Boreiko & Sahdev, 2018).
Transaction: A cryptocurrency transfer from one address to another (Antonopoulos, 2014).
Wallet: Software that holds cryptocurrencies and their secret keys. It sends, receives, and stores
cryptocurrencies (Antonopoulos, 2014).

Chapter Two
Review of Literature
Introduction
The primary purpose of the literature review is to share the results of other closely related
studies with the reader and provide a framework for establishing the importance of the study as
well as a benchmark for comparing the results with other findings (Creswell & Creswell, 2018).
Cooper (2015) mentioned four types of literature reviews that integrate what other researchers
have done and said, criticize previous scholarly works, build bridges between related topics, and
identify the central issues in a field. Quantitative research includes substantial literature to guide
the research questions or hypotheses (Creswell & Creswell, 2018). Wang et al. (2020) stated that
the research methodology contains two main parts: examining the literature and conducting a
pilot study. Hence, an extensive literature review was conducted on blockchain technology, its
characteristics, and cryptocurrency as its application.
Chapter two included the background of blockchain, its characteristics, brief information
about some cryptocurrencies, and research variables. The theoretical details of the technology
acceptance model (TAM), Diffusion of Innovations (DOI), and the Unified Theory of acceptance
and use of technology (UTAUT) are discussed. The literature review discussed blockchain
technology and its applications as a cryptocurrency.
Ghonimy (2021) revealed that identifying the main factors influencing the new
technologies would assist organizations in smooth transitions to adopt new technologies like
Blockchain technology. Conrad (2009) acknowledged that studying the factors influencing
individual attitudes toward using new technology begins with examining the existing literature
regarding these factors to gain insight into blockchain technology and cryptocurrency as its
application, advantages, and challenges. The Grover M. Hermann Library from the University of
the Cumberland was the leading resource for the academic literature review articles and research
papers, which consists of 105 Databases such as APA PsysARTICLES, APA PsycBOOKS, APA
PsysINFO, APA PsysTESTS, IEEE Electronic Library (IEL), Statista, Purdue OWL – APA,
ProQuest Dissertation and Theses. The additional resources include but are not limited to
peerreviewed literature, white papers, Google Scholar, industry articles, MDPI Journals,
Springer, and Wiley Online Library. The researcher used keywords such as “Blockchain”,
“Blockchain
Technology”, “Cryptocurrency”, “Blockchain adoption”, “Blockchain challenges”, “Technology
Acceptance Model”, “The Unified Theory of Acceptance and Use of Technology”, “Diffusion of
Innovations”, and “Decentralized finance” was used to search for relevant research articles. The
researcher further reviewed and selected the most relevant articles based on the research
objective.
As civilization progressed, the format of money has changed considerably, i.e., from
commodity-backed money to paper money and digital in recent years (Piedade, 2018). Bratspies
(2018) highlighted that fiat currencies dominate the modern monetary system, as fiat currencies
have no intrinsic value regulated by governments. A currency must serve as a store for value, be a
unit of account, and function as a medium of exchange, which are the three requirements to be
considered as money (Bratspies, 2018). The first digital currency, called DigiCash, was created in
the early 1990s; However, the first cryptocurrency, Bitcoin, was introduced by Satoshi Nakamoto
in 2008 (Piedade, 2018). An economic revolution began to build a more secure and decentralized
global financial network following the 2008 financial crisis and the collapse of many major
United States financial institutions (Nakamoto, 2008). Boucher (2017) emphasized the
importance of blockchain-based cryptocurrencies over traditional ledgers and how blockchain
technology could change our lives. Innovations are developed for different purposes, and
individuals mainly empower adaption (Khasawneh, 2021). Khan et al. (2021) mentioned that
blockchain technology is one of the most transformative technologies in the current era and has
created hype and optimism while gaining attention from both the public and private sectors.
Garay et al. (2020) extracted and analyzed the core of the Bitcoin protocol, also termed the
Bitcoin backbone. Attili et al. (2016) stated that Blockchain establishes trust and integrity
without reliance on third-party intermediaries. Bitcoin, a public blockchain application, impelled
research and development into blockchain technology (Khan et al., 2021). The first
cryptocurrency, Bitcoin, was created by Satoshi Nakamoto in 2008 and became popular after the
outbreak of the financial crisis in 2009 (Stavros, 2017). Zheng et al. (2018) conducted a
comprehensive survey on blockchain technology, which contained blockchain applications,
taxonomy, and consensus algorithms, and discussed technical challenges and advances in
tackling those challenges.
Janssen et al. (2020) performed a systematic literature review on the institutional, market,
and technical factors affecting blockchain adoption and outlined the complex relationships
between these factors. Decentralized cryptocurrencies like Bitcoin and Ethereum are widely
deployed in many sectors (Khan et al., 2021). Khan et al. (2021) concluded that on-chain and off-
chain are the two significant categories of scalability solutions. Block size expansion, sharding,
and consensus mechanisms are examples of on-chain solutions, whereas a lighting network is an
example of an off-chain solution (Khan et al., 2021). Khan et al. (2021) mentioned that although
scalability is one of the critical issues in implementing public blockchain, it has yet to be well-
defined in the literature. Blockchain technology may face technological, governance,
organizational, and societal obstacles to revolutionizing some sectors (Zheng et al., 2018).
Fang et al. (2022) mentioned that cryptocurrencies had experienced broad market
acceptance and fast development despite recent conception. Stavros (2017) provided a
quantitative analysis of the decentralized Bitcoin network transactions in the blockchain to draw
valuable conclusions about the new payment system. Bitcoin’s success depends on whether it
can scale to support the high volume of transactions required for a global currency system
(Sompolinsky & Zohar, 2013). Sompolinsky and Zohar (2013) investigated the restrictions on the
transaction rate as a function of the bandwidth of the available nodes and the network delay,
which lower the efficiency of Bitcoin’s transaction rate. Silva and Mira da Silva (2022)
researched cryptocurrency regulation contributions and the challenges that need to be addressed
for future studies. Silva and Mira da Silva (2022) revealed that the leading cryptocurrency
regulatory challenges are cryptocurrency adoption, central bank digital currency regulation,
accounting for cryptocurrencies, and risk for cryptocurrencies. Nabilou (2019) proposed a
nuanced policy solution for regulatory restructuring in the cryptocurrency ecosystem, which
relies on a decentralized regulatory architecture built upon the existing regulatory infrastructure
and utilizes the current and emerging intermediaries in the industry. Alshamsi and Andras (2019)
investigated users’ perceptions and experiences of Bitcoin and its influence on users in terms of
usability and security in comparison with credit and debit cards.
Wibowo (2019) mentioned that acceptance models and theories are much more relevant
in information science to understand factors of the acceptance or rejection of new technologies
and systems. Conrad (2009) used attributes of diffusion of innovations (DOI) and technology
acceptance model (TAM) as these instruments have been proven to be highly valid for measuring
an individual intention to use new information technologies across many studies. Khasawneh
(2021) utilized the diffusion of innovations theory to analyze how new technology can be
adopted during a crisis. Hebron (2008) developed a hypothesized model based on TAM, UTAUT,
and DOI to identify the impact of wireless trust and social psychology settings on the diffusion of
innovations by surveying the perception of IT managers and daily technology users.
The first section of the literature review provided a background of blockchain technology,
its advantages and disadvantages, and cryptocurrencies as its application. The key factors
affecting cryptocurrencies are then thoroughly discussed in the second section of the literature
review, which includes research variables like Perceived Usefulness (PU), Perceived
Ease of Use (PEOU), Compatibility (COMPB), Complexity (COMPX), and Social Influence
(SI). AlShamsi et al. (2022) revealed that the technology acceptance model (TAM) and
technology-organization-environment (TOE) were the most used models for understanding the
factors affecting the use and adoption of Blockchain technologies. Alzahrani (2021) mentioned
that the blockchain is in the early stage of maturity, complexity, and scarcity of implementations.
Blockchain
Boucher (2017) mentioned that it is worth knowing how the traditional ledgers work
before attempting to understand blockchain. Furthermore, Boucher (2017) illustrated that for an
extended period, banks had utilized ledgers to keep track of account transaction databases. A
central authority or the bank or government organization maintains the records of transactions
and can verify account details (Boucher, 2017). Although digitization has made these ledgers
faster and easier to use, these traditional ledgers are centralized as there is a middleman trusted
by all users who control the overall system and black-boxed as the functioning of the ledger is
not fully visible to its users (Boucher, 2017).
The blockchain is the major innovation that gives life to Bitcoin and other
cryptocurrencies (Stavros, 2017). Fang et al. (2022) defined the blockchain as a digital ledger of
economic transactions that can be used to record financial transactions and any object with an
intrinsic value. Stavros (2017) mentioned that blockchain incorporates two things into its
architecture. First, it stores all transactions since its genesis in a distributed ledger, and second, it
is designed to have the technical adjustments needed to maintain its records securely (Stavros,
2017). Blockchain’s decentralized characteristic is facilitated by integrating technologies like
cryptographic hash, digital signature, and distributed consensus mechanism (Zheng et al., 2018).
Many online transactions between individuals or organizations are controlled by a centralized
controlled system or by a third-party organization (Khan et al., 2021). This third-party
organization can be a bank or a credit card company executing a digital payment between two
organizations or individuals charging a fee for every successful transaction (Khan et al., 2021).
Centralization: The centralized authority or the third-party organizations control the
money transfer traditionally (Sompolinsky & Zohar, 2013). A centrally controlled organization
can freeze the account, seize the money, and charge high transaction fees. In contrast, the Bitcoin
network uses the nodes to verify transactions and ensure that no single entity can misbehave
(Sompolinsky & Zohar, 2013). Blockchain’s decentralized nature helps save costs and improve
efficiency (Zheng et al., 2018). All the nodes in the network have a copy of all the information,
allowing each node to be fully operational as part of the money transmission system
(Sompolinsky & Zohar, 2013).

Figure 3 illustrates a simplified example of a blockchain structure consisting of
continuously linked blocks. As shown in Figure 3, the blockchain is a series of cryptographically
linked blocks containing a list of transactions (Khan et al., 2021). Every block points to the
immediately previous block using the previous block's hash value, also called the parent block,
up to the first block (Woodside et al., 2017; Zheng et al., 2018). The first block in the chain is
called a Genesis block with no previous block (Zheng et al., 2018). A block contains the block
header, which carries the metadata like block version, previous hash timestamp, Merkle tree bits,
Nonce value, etc., and the block body, which has a list of transactions and a transaction counter
(Khan et al., 2021). The block size and the size of each transaction determine the maximum
number of transactions a block can contain (Zheng et al., 2018). The blockchain size grows as
the interaction between users, miners, and nodes increases (Bratspies, 2018).

Figure 4 shows the workflow of blockchain transactions. Fang et al. (2022) defined a
blockchain as a series of immutable data records with timestamps managed by a cluster of
machines that do not belong to any single entity. Cryptocurrencies are managed on a peer-to-peer
network where each peer has a complete history of all transactions along with the balance of each
account (Fang et al., 2022). For example, when person A pays X Bitcoins to person B, a
transaction gets signed by person A using its private key, and transactions are broadcast on the
network.
Figure 5 shows an example of the digital signature used in blockchain. Khan et al. (2021)
defined the digital signature as asymmetric cryptography deployed in a trustless environment.
The signing and verification phases are the two typical digital signature phases involved (Zheng
et al., 2018). Stavros (2017) mentioned that the digital signature is an important feature of the
public key cryptography used in Bitcoin. It verifies that a message created by the owner of the
signature has not been altered, and the signer cannot deny it (Stavros, 2017). Khan et al. (2021)
stated that every block in the blockchain is assigned a public and private key where the private
key is only accessible to its owner for signing in the transactions, and the public key is visible to
every node in the blockchain network to access the signed transaction that was broadcasted
across the network. As shown in Figure 5, if Alice wants to transfer cryptocurrency to Bob. First,
to sign a transaction, Alice generates a hash value using the hash function for the transactions,
encrypts this hash value using her private key, and sends an encrypted hash with the original data
to Bob (Zheng et al., 2018). Then, Bob verifies the received transaction by comparing the
decrypted hash using Alice’s public key and the value derived from the received data by the hash
function Alice used while signing the transaction (Zheng et al., 2018).

The consensus mechanism indicates how every node agrees on the verified state of the
ledger to avoid the double-spending issue (Zheng et al., 2018). Garay et al. (2020) explained that
a double-spending attack occurs when the attacker credits an account to receive service or goods
from the account holder but then alters the transaction ledge to revert the transaction that credits
the account holder. This way, the attacker keeps his Bitcoin while receiving services and can
spend it again somewhere else (Garay et al., 2020).
Nakamoto provided an initial workflow on how the Bitcoin system will prevent
doublespending attacks (Garay et al., 2020). A double-spending attack can be prevented by
introducing a confirmation lag into transactions by waiting for some blocks before completing
the transactions, making it difficult to alter the transactions (Chiu & Koeppl, 2017; Hellani et al.,
2018). The two types of consensus mechanisms are proof-based and voting-based mechanisms
(Zheng et al., 2018). The proof-based consensus mechanism is utilized in public or
permissionless blockchains, whereas the voting-based consensus mechanism is used in the
private blockchain (Zheng et al., 2018). Proof-of-work (PoW) and Proof-of-stake (PoS) are
examples of the proof-based mechanism, whereas the Practical byzantine fault tolerance (PBFT)
is an example of the voting-based mechanism (Zheng et al., 2018). Miners compete to solve a
cryptographic puzzle to receive a Bitcoin reward, resulting in a new block to add to the Bitcoin
blockchain called a proof-of-work (Bratspies, 2018).
Hafid et al. (2020) revealed that Proof-of-work is criticized for its higher energy
consumption. Khan et al. (2021) mentioned that PoS can process transactions much faster than
PoW but is vulnerable to risks such as Agency issues. Ethereum is implementing the PoS
consensus mechanism to improve scalability and reduce energy consumption (Khan et al., 2021).
Furthermore, Hafid et al. (2020) added that a single Bitcoin transaction consumes about 729 kWh
of electricity, which can power 24 U.S. households for a day. Apart from higher energy
consumption, Proof-of-work blockchain protocols suffer from their low throughput; therefore,
the blockchain community has proposed various consensus methods like Proof-of-Stake (PoS),
Delegated Proof-of-Stake (DPoS), Stellar Consensus Protocol (SCP), Proof of Authority (PoA),
Proof of Elapsed Time (PoET), and Proof of Retrievability (PoR) (Hafid et al., 2020).
Cryptocurrency
In the following section, the main aim is to understand cryptocurrency, its characteristics,
advantages, and disadvantages. Understanding the difference between virtual currency, digital
currency, and cryptocurrency is essential (Piedade, 2018). While elaborating on the difference,
Piedade (2018) stated that a virtual currency is a type of unregulated digital money issued and
controlled by its developer and used and accepted among the members of a specific virtual
community. In contrast, a digital currency is a form of virtual currency that is electronically
created and stored. Doran (2014) defined cryptocurrency as a decentralized medium of exchange
that uses cryptographic functions to conduct financial transactions. Cryptocurrencies use
blockchain technology to gain decentralization, transparency, and immutability features (Fang et
al., 2022).
Cryptocurrencies are digital exchanges based on cryptography to secure ownership and
transactions and create new means of currency (Stavros, 2017). Bitcoin was the first
cryptocurrency launched in 2009 and is still one of the most widely accepted and circulated
cryptocurrencies (Stavros, 2017). Cryptocurrencies are decentralized, as these cryptocurrencies
are not controlled by any government or financial institutes like other currencies (Janssen et al.,
2020). Although Blockchain technology proliferates across different industries, like logistics
operations, manufacturing, public sectors, and financial services, Cryptocurrency is the most
common application of blockchain technology in the financial sector (Janssen et al., 2020).
Crypto tokens are types of virtual currency that reside on their blockchains, representing a utility
or asset (Buterin, 2013; Wood, 2014). These crypto tokens can be used for 1) cryptocurrencies, 2)
tokenized securities/ investment tokens, and 3) utility tokens (Benoliel, 2017).
Piedade (2018) revealed that cryptocurrencies and their market capitalization have been
increasing, which has attracted more people to invest in cryptocurrencies like Bitcoin, Ethereum,
Ripple, Litecoin, and more. Bitcoin was the first cryptocurrency to be introduced, and in 2015,
Ethereum was created (Piedade, 2018). Since their inception, both cryptocurrencies have
dominated the cryptocurrency market (Piedade, 2018). Stavros (2017) mentioned that the Bitcoin
network, a distributed payment system, contains all valid transactions with additional details of
all addresses that send and receive funds, the amounts, dates, and other essential details for the
system to be functional. Using cryptocurrency blockchain technology, decentralized peer-to-peer
software license validation methods can protect software copyright (Herbert & Litchfield, 2015).
One vital advantage cryptocurrency provides is that the transactions are instantaneous and
borderless; unlike traditional transaction methods, which restrict users by business hours,
holidays, and transfer limits, cryptocurrencies do not impose any limitations on the time, place,
or amount of their transactions (Huang, 2015).
Bitcoin uses cryptography features like public and private keys and the cryptographic
validation of the transactions (Stavros, 2017). Public keys are known in the whole network,
whereas private keys are only known by their owners, and both keys are used for message
encryption (Stavros, 2017). Participants' private and public keys are needed for transactions to
occur in the Blockchain-based cryptocurrency ecosystem (Bugbee, 2019). Litecoin, also called
the silver to Bitcoin’s gold, was launched in 2011 due to its higher supply, and Ripple was
launched in 2012 (Piedade, 2018). According to the CoinMarketCap.com website, more than
3207 cryptocurrencies exist with a market capitalization as of February 2021 (Silva & Mira da
Silva, 2022).
Although it is not clear how many companies around the world accept cryptocurrencies as
a means of payment, the number of companies accepting cryptocurrencies as a payment has
increased (Vasin, 2018). Vasin (2018) studied the economic and technological research behind
the countries working on issuing their own national cryptocurrencies. The economic reasons
include enhancement of the overall financial situation, establishing a digital analog of their
current money that would allow them to circumvent sanctions, take cash turnover under control,
tracking the movement of digital money, fight with black market cash transactions and tax
evasion, to cut down costs associated with the physical forms of money, to broaden the financial
services and many other reasons (Vasin, 2018). The technological reasons include the ability to
integrate smart contracts in the infrastructure, which would reduce the costs for intermediaries,
make the process faster to make deals between two entities without excessive bureaucracy, and
ICOs (Initial Coin Offering) help in raising venture capital for the startup companies in the form
of cryptocurrencies (Vasin, 2018).
Cryptocurrency businesses raise money through an initial coin offering (ICO), an
unregulated crowd-funding alternative to the regulated capital-raising process performed by
venture capitalists, banks, or stock exchanges (Silva & Mira da Silva, 2022). Initial Coin
Offerings (ICO) can be described as a non-regulated means to raise funds for a new
cryptocurrency venture, which involves the opportunity for individual investors to exchange
currency such as US dollars or cryptocurrencies in return for a digital asset labeled as a coin or
token (Piedade, 2018). The typical procedure for a start-up is to publish a white paper with the
details about the utility of the tokens issued during the ICO; it should also contain what the
project is about, the main goal of the project, funding requirement, type of acceptable fundings,
duration of the ICO campaign and it must state the total number of tokens created (Piedade,
2018).
The growth of cryptocurrency brings associated risks, like hacking, black markets,
speculation bubbles, high power consumption, and liquidity risks without legal protection (Silva
& Mira da Silva, 2022). The unregulated characteristics of cryptocurrency markets lead to
volatility in the market, which results in significant theft, fraud, and price manipulation (Silva &
Mira da Silva, 2022). McCorry (2018) mentioned that Bitcoin and Ethereum are the most widely used
and successful cryptocurrencies, with market capitalizations of 37 billion US Dollars and 21 billion US
Dollars, respectively, in June 2017.
Cryptocurrencies have been described as “one of the greatest technological breakthroughs
since the internet,” as well as a “black hole” into which a consumer’s money could just disappear
(Piedade, 2018). With the growth of the public digital age, cryptocurrencies have become very
enticing to those looking for online privacy, as cryptocurrency transactions are protected by
electronic encryptions that ensure the user’s anonymity (Huang, 2015). While cryptocurrencies
may have various applications in legal endeavors, the anonymous nature of online transactions
has involved cryptocurrencies in many criminal activities (Huang, 2015; Madey, 2017). Silk
Road, a well-known online Black-market site, exploited the anonymity of Bitcoin to engage in
illegal activities (Huang, 2015). Huang (2015) mentioned that it has become very important for
government regulatory organizations to update with the rise of cryptocurrencies. Although the
government has shut down Silk Road, the other black-market websites have replaced its place
and continue to operate and exploit cryptocurrencies for illegal activities (Huang, 2015). Bugbee
(2019) stated that limiting factors must be addressed for cryptocurrencies to achieve widespread
acceptance and usage; however, the very design of the blockchain system is currently of
detriment to scalability without altering fundamentals of consensus protocol and anonymity.
Well-known Cryptocurrencies
The main objective of this section was to introduce emerging cryptocurrencies and how
these cryptocurrencies differ from each other. Every cryptocurrency has its own characteristics,
advantages, and disadvantages, as well as some common aspects (Piedade, 2018) . Here, some of
the well-known cryptocurrencies were analyzed in detail, allowing us to understand how these
cryptocurrencies have emerged and have been evolving, and have their unique characteristics.
Bitcoin
Bitcoin was introduced by the pseudonym developer Satoshi Nakamoto in 2008, and in
2009, Bitcoin software became open source worldwide (Nakamoto, 2008). Bitcoin founder
Satoshi Nakamoto described Bitcoin as an electronic payment system based on cryptographic
proof instead of trust, allowing any two willing parties to transact directly without needing a
trusted third party (Nakamoto, 2008). Nakamoto wrote the Bitcoin white paper during the 2008
financial crisis when the trust in the government and the banks to manage the economy was at its
lowest point (Bratspies, 2018). The double-spending issue happens when a person sends the
same funds to two receivers, and it is seen as one of the most critical issues in cryptocurrencies
(Rosenfeld, 2014). Bitcoin protects against double spending by verifying each transaction added
to the blockchain to ensure that the transaction's inputs have not already been spent
(Antonopoulos, 2014). A person can buy Bitcoin using real money or exchange other
cryptocurrencies exchange for selling products or services or through mining (Huang, 2015).
The decentralized characteristic of cryptocurrencies is the main differentiating factor
from traditional currencies (Bugbee, 2019). The Bitcoin ecosystem allows transactions to be
conducted quickly, globally, and pseudo-anonymously (Bugbee, 2019). Bugbee (2019) provided
an example of how two entities may utilize Bitcoin technology to perform transactions compared
to the traditional way. If Company A, a Canadian business, wants to perform the transaction with
Company B in Great Britain, there is an urgency on both sides to get this transaction done, as
delay will cost each company (Bugbee, 2019). The traditional way of performing the transaction
involves some intermediary organization or central authority, associated transaction fees,
taxation, currency conversion costs, and there’s no anonymity; also, this transaction would take a
few days to weeks to be fully authorized and executed (Bugbee, 2019). On the contrary, If
Company A could utilize the decentralized Bitcoin ecosystem to execute the transaction to
Company B, then there would be no currency conversion cost, a lower transaction fee,
maintaining anonymity, and the transaction would be executed in 15-20 minutes (Bugbee, 2019).
Basically, the Bitcoin ecosystem provides the ability to conduct transactions freely and globally
(Bugbee, 2019).
Mining in cryptocurrency means solving complex mathematical problems with the
computing power of a computing node. Anyone with sufficient computing power can join the
mining network to mine Bitcoin and leave it anytime (Sterry, 2012). Mining Bitcoin is a core
function in the governance of the Bitcoin blockchain. Participants who provide computing power
to help solve the cryptographic problem on the blockchain are called miners (Sterry, 2012).
Consensus protocol affirms that when 51% of miners agree on the nonce and hash of the block,
the block is accepted (Bugbee, 2019). Once the consensus protocol is attained, all the
transactions for that block are executed and recorded permanently within the block (Bugbee,
2019). Consensus Protocol is transaction authentication that allows all community members to
agree on information, or values, stored in the ledger (Bugbee, 2019). When several nodes,
usually most nodes on the network, all have the same blocks in their locally validated best
blockchain (Antonopoulos, 2014). Since mining is a complicated process, most individuals
obtain Bitcoin from a local cash exchange or an online Bitcoin exchange, similar to traditional
currency exchange systems like banks and third-party services that facilitate the currency transfer
(Huang, 2015). This mining procedure for cryptocurrencies is based on the Proof-of-Work
consensus mechanism, which depends on the cryptocurrencies, as different cryptocurrencies use
different consensus mechanisms. Transactions are verified through mining, avoiding
doublespending issues, and miners collect transaction fees as a reward (Sterry, 2012).
Bitcoin mining allows a new block to be created every 10 minutes, and 50 bitcoins were
given in 2009 as a reward to miners who helped solve complex mathematical problems to verify
transactions (Sterry, 2012). This reward value halves every four years, eventually ending in 2140
(Sterry, 2012). This incentive process helps to generate 210,000 blocks of Bitcoin every four
years. Powerful GPUs, FPGA, and ASIC systems are being used for Bitcoin mining, making it a
very energy-consuming procedure (Sterry, 2012). In 2009, when the first Bitcoin block was
created, the mining process was easy as there was no need to go over previous ledgers. As more
users started utilizing the system, the mining process became more complex and expensive as
time passed (Sterry, 2012). McCorry (2018) revealed that Bitcoin does not support the creation
of smart contracts due to its limited scripting feature, which led to the rise of Ethereum, the
second most popular cryptocurrency in terms of market capitalization.
Ethereum
Ethereum came to life after Vitalik Buterin’s white paper and crowd-funding campaign
(Boucher, 2017). Ethereum provides the ability to develop decentralized software protocols by
creating custom software contracts on the Ethereum blockchain. Ethereum is a decentralized
computing platform with its Turing-complete programming language (Hileman & Rauchs,
2017). Since its launch, Ethereum has attracted much interest from developers and organizations
(Boucher, 2017). According to the Ethereum Foundation (Buterin, 2016), Ethereum is a
decentralized platform that runs smart contracts, which are applications that run precisely as
programmed without any possibility of downtime, censorship, fraud, or third-party influence.
Ethereum’s developer Vitalik Buterin compares it to Oil, as it is used in many sectors and
technologies worldwide like oil. Ethereum transactions take around 15 seconds, faster than
Bitcoin transactions, which take 10 minutes (Hasanli, 2021). Although Bitcoin and Ethereum are
developed using blockchain technology, these cryptocurrencies differ in many ways. Ethereum is the
second-largest cryptocurrency after Bitcoin by market value. The updated Ethereum blockchain,
Ethereum 2.0 or Eth2, can handle 100.000 transactions per second, resolving some scalability issues
(Hasanli, 2021). McCorry (2018) mentioned that Ethereum has a Blockchain that is governed by a
decentralized network of peers and provides a programming language to develop smart contracts.
Marsal-Llacuna (2018) and McCorry (2018) described smart contracts as the conditions of an
agreement between two or more parties enforced using the same consensus protocol that secures the
Blockchain. Solidity is a popular high-level programming language for writing smart contracts
(McCorry, 2018).
Ripple
Ripple is a global system for reciprocal payments that allows transfers in almost every
currency around the world in a few seconds (Vasin, 2018). XRP is an intermediary
cryptocurrency that allows the exchange of any other currencies on the Ripple platform (Vasin,
2018). XRP was built for enterprise use, and it offers banks and payment providers a reliable,
ondemand option to source liquidity for cross-border payment transactions in real time and lower
exchange costs (Vasin, 2018). XRP is one of the fastest-growing cryptocurrencies, which can
handle 1,500 transactions per second (Vasin, 2018). Centralization, focus only on banks, limited
focus, usefulness over a long period, and private blockchain are the main drawbacks of Ripple
(Vasin, 2018). Ripple is the only cryptocurrency that works on a global consensus ledger instead
of a blockchain (Piedade, 2018). Large financial organizations use the Ripple protocol. XRP is
the native token of the Ripple cryptocurrency. Ripple was developed in 2012 to enable secure,
instant, and nearly free global financial transactions (Piedade, 2018).
Litecoin
Litecoin was launched in 2011 and is considered the “silver” to Bitcoin’s “gold” because
of its sufficient total supply of 84 million LTC compared to BTC’s 21 million (Van Rooij et al.,
2011). Litecoin’s architecture is like Bitcoin except for some parameters like the mining
algorithm. Litecoin organization is a peer-to-peer digital currency that enables instant, low-cost
payments to anyone worldwide. (Piedade, 2018).
Blockchain Characteristics
The fundamental characteristics of Blockchain technology enable implementation in a
wide range of sectors. There are a few characteristics that make blockchain valuable technology
in many sectors. This section briefly explains the key attributes of blockchain technology.
Decentralization: The transactions happen peer-to-peer without requiring any central
entity to validate and process the transaction (Khan et al., 2021). Each participant has full access
to the database to verify the transaction without needing a central authority. The transactions are
decentralized by integrating key technologies like cryptographic hash, digital signature, and
distributed consensus mechanisms (Ølnes et al., 2017). The decentralization feature ensures that
no centralized entity exists that can be vulnerable and create security attack risks (Ølnes et al.,
2017).
Anonymity: Each user on the blockchain has a unique private identification and a public
key (Zheng et al., 2018). All transactions on the Bitcoin blockchain are public and anonymous, as
every user can see all transactions for the Bitcoin blockchain (Madey, 2017). These transactions
associated with a wallet are public but not an individual or known entity, so anyone on the
blockchain can see all transactions between wallets, but the user’s identity is anonymous (Madey,
2017). Transactions can be traced only to the wallet address, and a person can possess multiple
wallets, so it isn't easy to trace a wallet to a particular person (Madey, 2017). While the central
authority keeps a record of the users and their private information in traditional transaction
systems, the blockchain allows privacy (Zheng et al., 2018).
Auditability: Ølnes et al. (2017) defined an audit as a systematic examination of the work
by an independent party. Blockchain governance takes advantage of public-keeping features like
universal, permanent, continuous, consensus-driven, publicly auditable, redundant, and
recordkeeping repositories (Swan, 2015). Each transaction in the blockchain is validated and
stored with a corresponding timestamp that users can verify and trace the previous records
(Zheng et al., 2018). Each transaction can be traced back to previous transactions persistently in
the Bitcoin blockchain. This improves the transparency and traceability of the data stored in the
blockchain (Zheng et al., 2018). Blockchain technology can streamline audits and better control,
which eventually results in more trust (Ølnes et al., 2017).
Immutability: Blockchain can be used in a wide range of applications to embed
information and instructions for an irreversible and temper-proof public records repository for
documents, contracts, properties, and assets (Atzori, 2015). As the transactions are recorded in
different nodes in the distributed network, and the copy of the blockchain is continuously
synchronized with other copies, it is almost impossible to tamper with the public blockchain
(Zheng et al., 2018). This architecture provides no centralized point of vulnerability that
computer hackers can exploit, and taking one or a few nodes down will not lead to a breakdown
of the blockchain (Ølnes et al., 2017). This point-to-point (P2P) architecture contributes to the
security and immutability of the transactions that are recorded in the blockchain (Ølnes et al.,
2017).
Persistency: Each transaction spread across the blockchain network must be confirmed
and stored in the block distributed in the whole network, so it is impossible to tamper (Zheng et
al., 2018). Other available nodes validate each broadcasted block to detect falsification, and
transactions are verified (Zheng et al., 2018). The distributed consensus protocol ensures the data
integrity of the transactions in the blockchain (Ølnes et al., 2017).
The level of openness and the allocation of permissions categorize the blockchain
systems into different types (Ølnes et al., 2017). Blockchain systems can currently be categorized
into three types. 1) Public blockchain, 2) Private blockchain, and 3) Consortium or Permissioned
blockchain (Buterin, 2014, 2015). Whether the blockchain ledger is public or private determines
who has access to copies of the ledger, whereas the attribute of permissioned versus
permissionless determines who maintains the ledger (Ølnes et al., 2017). Transactions in a public
blockchain are visible to the public, while the consortium and private organizations could decide
whether the stored information in a blockchain is public or restricted (Buterin, 2015). The main
difference between these three types of blockchain is that public blockchain is decentralized,
consortium blockchain is partially centralized, and private blockchain is fully centralized as a
single group or an entity may control it (Zheng et al., 2018).
Anyone around the world can join the consensus process of the public blockchain. In
contrast, consortium and private blockchains require permission and certification to participate in
the consensus process (Zheng et al., 2018). As a public blockchain is decentralized, authorityfree,
and self-governed, anyone can join, leave, contribute, read, and audit the Blockchain network
(AlShamsi et al., 2022). Bitcoin blockchain is an example of a public blockchain (AlShamsi et
al., 2022). The private blockchain is a closed network with a verified and authentic invitation
available for selected and trusted parties, which means only the blockchain owner has the
authority to edit, delete, or override entries on the Blockchain (AlShamsi et al., 2022).
Permissioned blockchain permits anyone to join after their identity is verified; everyone is given
specific permission on the network to perform a particular task (AlShamsi et al., 2022). For
example, In the supply chain pipeline, the supplier can manage a permissioned Blockchain for
their business partners and customers with different access rights, where customers can only be
allowed to read the product documents, whereas suppliers and wholesalers can modify
information about the goods and delivery (AlShamsi et al., 2022).
When making a transaction, each node in the blockchain network broadcasts the
transaction, including the number of transactions, the recipient of the transaction, and the node's
public key to receive the amount (Madey, 2017). It takes a long time to propagate transactions,
blocks as many nodes on the public blockchain network, and increases as time passes (Zheng et
al., 2018). There are fewer validators, so consortium and private blockchains could be more
efficient than public blockchains (Zheng et al., 2018). This brought us to the discussion of
scalability, one of the most significant challenges of blockchain technology.
Scalability is one of the challenges faced by blockchain technology, and it creates much
concern about the future of the Bitcoin network and the possible approaches to surpassing it
(Harwood-Jones, 2016). The transactional volumes required by some of the services are much
higher than those required for Bitcoin transactions; blockchain technology needs to be more
mature to provide much higher throughput at the current stage (Harwood-Jones, 2016). The
degree of the challenge will rely on the applications; for example, scalability will be less of a
concern for low-market segment applications, while scalability will be critical for high-volume
products (ESMA, 2017). Some blockchains are more complex to scale because of their consensus
procedure. Transaction processing can be slow on blockchains when more users exist on the
network than it can handle, while some blockchains require higher energy consumption, so it can
be challenging to integrate blockchain with several legacy systems (Iredale, 2020).
Scalability is currently an issue between public and private blockchains (Attili et al.,
2016). In a public blockchain like Bitcoin, thousands of nodes store copies of the relevant data,
increasing transaction volumes to preserve decentralization. Only nodes interested in successfully
processing the transactions are running in private blockchains. Blockchains are not ideal for
high-frequency trading applications because of delays introduced by the linked blockchain nodes'
asynchronous, ad-hoc, peer-to-peer nature. There are challenges with throughput capacity and
storage limits related to permissions (Attili et al., 2016).
Block.one’s EOS.io, which was launched in early 2019, presents it as a decentralized
application hosting platform that can operate smart contracts and decentralized storage enterprise
solutions focusing on resolving the scalability issue of existing blockchains like Ethereum by
enabling millions of transactions per second (Lee et al., 2018; Shah, 2019). IBM has also
launched Blockchain as a Service (BaaS) open-source blockchain architecture that enables
scalable, high throughput trusted networks across private, public, and government actors (Miller,
2017; Vukolić, 2015). Patel et al. (2018) examined possibly the most mainstream open-source
storehouse, GitHub, to estimate cryptocurrency development quantitatively. Kim et al., (2021)
demonstrated how to configure cryptocurrency incentive mechanisms and how organizations can
operationalize governance using token economics.
The time needed to process the transaction is another challenge for cryptocurrency
adaptation. The time to process transactions for the Bitcoin network is only seven transactions
per second (TPS), which is comparatively less compared to other transaction processing
alternatives like VISA (2000 TPS typical, 10000 TPS peak), and the Twitter network performs
5000 transactions per second, respectively. Such a speed issue may limit the scalability of the
blockchain network. Because of the Low transaction speed of Bitcoin, it is incapable of dealing
with high-frequency trading. All blocks are stored on every node in the distributed system of the
blockchain, which also creates the issue of speed and scalability. To resolve this limitation, the
size of each block should be increased, leading to other problems like size and blockchain bloat
(Swan, 2015). Bitcoin block size is limited to 1MB, and the processing time of one Bitcoin
block is 10 minutes, meaning it will take a minimum of 10 minutes for the transaction to be
confirmed, while for a VISA, it takes just a few seconds. However, it will take longer for large
transactions as it must outweigh the cost of a double-spend attack- the same coins are spent
multiple times (Swan, 2015). Therefore, the tradeoff between block size and security has become
another challenge (Zheng et al., 2018). The current size of a Bitcoin blockchain is 160GB, which
already takes a long time to download. If processing speed increases to 2000 TPS (VISA
standards), it would be 1.42 PB/year. As a result, it will lead to a problem called “bloating”
(Swan, 2015).
IBM developed a blockchain solution to process up to 3500 transactions per second
(Schatsky et al., 2018). Transactions can be stored on the chain and other transactions off the
chain to reduce the overall load on the private blockchain, improving performance and scalability
(Schatsky et al., 2018). Many small transactions on the Bitcoin blockchain get delayed as miners
prioritize transactions with a high transaction fee. A larger block size would eventually slow the
propagation speed, leading to blockchain branches, so the scalability problem is critical (Zheng
et al., 2018).
As a blockchain grows, the system's scalability can be compromised because only users
with large storage spaces and computational power can partake in the blockchain as miners or
full nodes (Zheng et al., 2018). To resolve this issue, the blockchain supports three types of
nodes: full, light, and archive (Zheng et al., 2018). Full nodes process every transaction and store
every block in the blockchain. On the other hand, light nodes only store block headers, including
the previous block's hash, the Merkle Root, and the nonce (Zheng et al., 2018). By storing the
block header, the light node can verify that certain transactions have not been altered without
committing large portions of memory to the blockchain. Light nodes can also access specific data
as required (Zheng et al., 2018).
Rustem et al. (2019) highlighted the usage of cryptocurrencies in criminal activities and
why there’s a need to introduce criminal laws to prevent unlawful encroachment in
cryptocurrency (Rustem et al., 2019). The anonymity of using cryptocurrencies, decentralized
functionality, and lack of legal laws and regulations are a few factors that fuel the participation of
cryptocurrencies in criminal activities. The use of malicious tools and software to generate
cryptocurrency illegally, DDoS attacks, laundering, illegal trafficking of narcotics, drugs,
weapons, and other prohibited items, and cyber fraud are among the several types of most
common crimes using cryptocurrencies (Rustem et al., 2019).
Theoretical Frameworks
The Technology Acceptance Model (TAM), Diffusion of Innovations (DoI), and the
Unified Theory of Acceptance and Use of Technology (UTAUT) are the three models that could
serve as a theoretical framework for this study as these frameworks are used in identifying the
factors influencing the decision to adopt the new technology. This section provided an
abbreviated description of these three frameworks. The main objective of this study is to measure
the influence of the five factors, the perceived usefulness, ease of use, social influence,
compatibility, and complexity on adopting cryptocurrency.
Technology Acceptance Model (TAM)
Wibowo (2019) stated that technology acceptance models and theories assist in
understanding how users adopt new technology and information systems. Park and Park (2020)
analyzed the factors of acceptance of information technology as per the characteristics of users
using the technology acceptance model. The technology acceptance model (TAM) is derived
from the theory of reasoned action (TRA) and the theory of planned behavior (TPB) (Arias-Oliva
et al., 2019; McConnell, 2009; Park & Park, 2020). Davis (1989) indicated in his initial research
that individuals had perceptions about information technology before deciding to adopt and use
it. Davis (1985) illustrated that the TAM fulfills two main objectives: it assists in understanding
the user acceptance processes, providing new theoretical insights into the successful design and
implementation of information systems, and it gives the theoretical basis for practical user
acceptance testing methodology to enable system designers to evaluate the proposed new
systems before implementing them. Hebron (2008) illustrated that TAM predicts information
system acceptance before users experience a new system.
Perceived usefulness and ease of use are the main factors affecting the attitude in the
technology acceptance model to explain IT users’ behaviors that utilize the relations among
belief attitude, intention, and behavior (McConnell, 2009; Park & Park, 2020).
Park and Park (2020) mentioned that it is essential to identify factors that make an individual
adopt new technology, as end users play a crucial role in utilizing the latest technology. Grover
et al. (2019) conducted research using the technology acceptance model for blockchain with
four factors: perceived usefulness, perceived ease of use, attitude towards use, and external
variables to examine tweets using social media analytics with data mining and statistical
approaches. Hebron (2008) reviewed the technology acceptance model, unified theory of
acceptance and use of technology, theory of reasoned action, and diffusion of innovation
models to explore factors influencing wireless data technology adoption. Sivo et al. (2018)
utilized the extended technology acceptance model to measure students’ beliefs about using the
online learning system.
Unified Theory of Acceptance and Use of Technology (UTAUT)
Venkatesh et al. (2003) theorized that four constructs, performance expectancy, effort
expectancy, social influence, and facilitating conditions, play a significant role as direct
determinants of user acceptance and user behavior. In contrast, gender, age, experience, and
voluntariness of use are four key moderators. The Unified Theory of Acceptance and Use of
Technology integrated the concepts of the Technology Acceptance Model, the Diffusion of
Innovations Model, and the Theory of Reason Actions, along with other models of technology
use and acceptance (Hebron, 2008). The Unified Theory of Acceptance and Use of Technology
(UTAUT) is based on TAM (Wibowo, 2019).

Venkatesh et al. (2003) tested UTAUT against the eight previously established models,
and UTAUT outperformed these eight individual models in determining the intention and usage
of new technologies. The main aim of the UTAUT was to help identify a single model through
which technology could be assessed and outcomes defined based on known models of user
behaviors and past research (Hebron, 2008).
Iftikhar et al. (2021) integrated the TAM model and TOE framework constructs and
proposed a theoretical framework for the adoption of blockchain technology. Iftikhar et al. (2021)
examined seven factors: relative advantage, perceived ease of use, perceived usefulness,
scalability concern, top management support, competitive pressure, and regulatory policy,
categorized in the technological, organizational, and environmental context. The UTAUT model
was instrumental in identifying the rate of adoption of IT (Hebron, 2008).
Diffusion of Innovations (DOI)
Rogers (2010) introduced four major factors for determining individuals’ behavior:
innovation, communication channels, time, and social systems. Rogers (2010) defined innovation
as an idea, practice, or object that is perceived by an individual. Rogers (2010) defined
communication as a process in which participants create and share information with others in
order to get a common understanding. Rogers (2010) defined diffusion as the process by which
an innovation is communicated and implemented over time through specific channels among the
members of a social system. Rogers (2010) suggested the five attributes of innovations, relative
advantages, compatibility, complexity, trialability, and observability, to predict the adoption rate
of new technologies, where the adoption rate is the relative speed with which an innovation is
adopted.
Figure 7
Diffusion of Innovations (DOI) Framework
Note. Adapted from “Diffusion of innovations” by Rogers, E. M., 2010, Simon and Schuster, p.
223. Copyright 2010 by the authors.
Rogers (2010) defined relative advantage as the degree to which an innovation is
perceived as being better than the idea it supersedes. Trialability is the degree to which an
innovation may be experimented with on a limited basis (Rogers, 2010; Rogers et al., 2014). In
contrast, Observability is the degree to which the results of an invention are visible to others
(Rogers, 2010). Basole (2006) mentioned that Rogers’ Diffusion of Innovations is one of the
most widely used and formalized models, explaining the mechanics of diffusion and the adoption
rate. Two of these five attributes, Compatibility and Complexity, are the focus of this study from
the DOI model and are discussed in detail in this chapter.
The theory of diffusion of innovations suggests that there are differences in the type of
persons who adopt new technologies (Hebron, 2008). Rogers (2010) mentioned that Innovators,
Early adopters, Early majority, Late majority, and Laggards are the five categories of adopters in
terms of readiness to respond to technology. Rogers (2010) exposed that most innovations follow
an S-shaped Rate of Adoption when plotted, where the X-axis indicates the time, and the Y-axis
indicates the adoption. Conrad (2009) mentioned that many diffusion publications referenced
Rogers’s diffusion on innovations theory at both organizational and individual levels. Rogers
(2010) exposed that innovation adoption follows a sequence of processes through which an
adopter passes before deciding to adopt technology or not.
Conrad (2009) utilized the diffusion of innovations (DOI) theory for the intention to use
new technology and used some of the concepts from the technology acceptance model to
reinforce DOI. Rogers’ Diffusion of Innovation model has been applied in many distinctive
scenarios and used in different conditions in which new technologies were integrated and user
adaptation was predicted (Hebron, 2008). Khasawneh (2021) used diffusion of innovations to
measure factors affecting technology adoption of virtual conference software in the workplace
during the COVID-19 pandemic. Arowolo (2017) examined six technological and organizational
factors using the combination of the diffusion of innovation theory and the technology
organization environment framework to determine the intention to adopt cloud computing.
Basole (2006) used the diffusion of innovations to analyze the complex technology adoption
decision in mobile information and communication technology.
Research Variables
This research was designed to explore the relationship between the variables influencing
the consumers’ behavior in the adoption of cryptocurrency. Arias-Oliva et al. (2019) stated that
identifying the key factors for customer acceptance of cryptocurrencies would assist the current
and future market players in focusing on the most important features a cryptocurrency should
have. This study was expected to encourage future academics to study other research variables
beyond those described in this study.
Intention to Use (IU)
Intention to use (IU) is the factor that shows the degree to which users are willing to
accept and use a new technology or an innovation (Davis, 1989). Behavioral intention is an
essential element in the theory of planned behavior (TPB) and the technology acceptance model
(TAM) (McConnell, 2009). Furthermore, McConnell (2009) mentioned that behavioral attitudes
and subjective norms affect the intention to use technology. Davis et al. (1989) identified the
intention to use as characteristic of adopters of the new technology and mentioned that
innovators and early adopters have a strong intention to use. In contrast, the other adopters tend
to reserve their intentions until more information about the new technology is available. This
variable is measured using a 7-point Likert scale.
Perceived Usefulness (PU)
Perceived usefulness (PU) is the degree to which an individual believes a particular
system would improve the individual’s performance (Davis, 1989). Park and Park (2020)
described the perceived usefulness as an indication of how much users believe using the new
technology improves their task achievement ability. McConnell (2009) illustrated that many
researchers agree that individual beliefs are the base for attitude toward technology acceptance,
and perceived usefulness is an individual belief that influences attitude toward technology
acceptance.
Sohaib et al. (2019) researched cryptocurrency adoption using the Partial Least Squares-
Structural Equation Modeling (PLE-SEM) based methods and Artificial Neural Network (ANN)
analysis. Arias-Oliva et al. (2019) studied the variables influencing cryptocurrency adoption from
a consumer-behavior perspective. Arias-Oliva et al. (2019), Ghonimy (2021), Kamble et al.
(2021), and Sohaib et al. (2019) showed that perceived usefulness significantly positively affects
cryptocurrency adoption. Improving performance is usually measured by increasing efficiency,
reducing the required time for operations, or ensuring the technology achieves the required
objectives (Ghonimy, 2021). This variable is measured using a 7-point Likert scale.
Perceived Ease of Use (PEOU)
Perceived ease of use (PEOU) is the degree to which users can use a particular system
without mental or physical stress (Davis, 1989). If the technology is easy to use, users will accept
the new technology positively. On the other hand, new technologies might negatively affect users
if the technology is not easy to use (Ghonimy, 2021).
Park and Park (2020) described the perceived ease of use as an indication of how much
users believe the system is easy to use. Hebron (2008) mentioned that perceived usefulness and
perceived ease of use are vital factors as users always evaluate new technologies based on the
improvement and benefit the new technology will add to current tasks, as well as the amount of
time and effort users need to spend to learn and adopt the new technology.
McConnell (2009) mentioned that knowledge is a vital part of an individual’s selfconcept,
including an educational level, life experiences, and shared social information. Knowledge plays
a crucial role in the perception of ease of use at various parts of technology acceptance. In
contrast, knowledge barriers determine an individual’s perception of ease of use of complex
technology innovations (McConnell, 2009). Perceived ease of use of the technology hinders trust
in blockchain (Ostern, 2018). Ghonimy (2021), Kamble et al. (2021), and Sohaib et al. (2019)
showed that the Perceived Ease of Use significantly positively affects cryptocurrency adoption.
Davis et al. (1989) revealed that an individual’s education level determines technology adoption.
This variable is measured using a 7-point Likert scale.
Compatibility (COMPB)
Moore and Benbasat (1991) defined compatibility as the degree to which an innovation is
perceived as consistent with existing values, past experiences, and needs of potential adopters.
Furthermore, Rogers (2010) added that innovation could be compatible or incompatible with
social-cultural values and beliefs, previously introduced ideas, or client needs for innovations.
Karahanna et al. (2006) described compatibility as the extent to which technology is consistent
with the current technologies. Yli-Huumo et al. (2016) mentioned the complexity of the
Blockchain application and how these applications have difficulty navigating.
Karahanna et al. (2006) noted that compatibility is a vital construct in technology
acceptance studies as it assesses the extent of coherence between the new technology and
different aspects of the individual and the position in which the technology will be used, but it is
missing from the TAM. Compatibility helps measure the degree of disruption and magnitude of
change the individual will likely experience when using new technology (Karahanna et al.,
2006). According to Kamble et al. (2021), compatibility issues with the existing system are a
hindrance to Blockchain technology adoption. Alzahrani (2021) mentioned that perceived
benefits, complexity, compatibility, data security, maturity, and relative advantage are the top
technological factors influencing the adoption of blockchain technology. This variable is
measured using a 7-point Likert scale.
Complexity (COMPX)
Rogers (2010) defined complexity as the extent to which technology could be difficult to
use or learn. Security is a significant barrier that can have a great influence on the use of
epayment systems (Alshamsi & Andras, 2019). Complexity and lack of usability may cause
security issues for online payment systems (Alshamsi & Andras, 2019). Rogers (2010)
mentioned that the complexity of innovation, as perceived by members of a social system, is
negatively related to its adoption rate. Rogers (2010) concluded that the complexity of an
innovation is negatively related to its adoption rate. McConnell (2009) stated that many
researchers found that complexity was an insignificant direct variable in their studies; However,
complexity was an indirect factor in relative advantage, perceived ease of use, and self-efficacy.
Arowolo (2017) illustrated that the complexity of financial services regulation is another hurdle
to cloud-computing adoption. Alzahrani (2021) illustrated that complexity is one of the top
technological factors influencing the adoption of blockchain technology. The complexity of the
new technology is represented by the level of ecosystem coordination involved in producing the
value. Basole (2006) mentioned that the complexity of technology decisions increases further
when technology is emerging, and its value is still unknown.
Chiu and Koeppl (2017) mentioned that Bitcoin and other cryptocurrencies face
scalability issues, and such systems will only be able to handle a large volume of transactions if
this issue is addressed. Franco (2014) mentioned that the size of the blockchain increased from
17 gigabytes in 2014 to 111.128 gigabytes in 2017. Scaling the transaction rate is the obstacle the
blockchain faces (Sompolinsky & Zohar, 2013). Credit cards are 10,000 times faster than Bitcoin
handling transactions (Decker & Wattenhofer, 2015). The block size limit and the block creation
rate are the main factors limiting the average number of transactions that can be added to the
blockchain (Sompolinsky & Zohar, 2013).
Kamble et al. (2021) mentioned that complexity is a technological factor influencing
blockchain technology adoption. Stavros (2017) mentioned that the scalability problem is one of
the major research subjects of the blockchain that creates much concern about the future of the
Bitcoin network and the possible ways of resolving it. Attili et al. (2016) stated that a public
blockchain stores copies of relevant content on thousands of nodes, which limits transaction
volumes. Khan et al. (2021) and AlShamsi et al. (2022) indicated that many hindrances restrict
blockchain acceptance in industries, and scalability is a key hurdle in implementing public
blockchains. While describing scalability as the main disadvantage of cryptocurrency, Fang et al.
(2022) stated that before the huge expansion of the technology infrastructure, the number of
transactions and the rate of transactions could not compete with traditional currency trading. In
March 2020, the Scalability issue led to a multi-day trading backlog, which affected many traders
(Fang et al., 2022). This variable is measured using a 7-point Likert scale.
Social Influence (SI)
Social influence is the degree to which an individual perceives that important others
believe he or she should use the new system or technology (Venkatesh et al., 2003). Wibowo
(2019) revealed that the TAM ignored the social influence on adopting technology, which limits
the scope of the implementation. Venkatesh et al. (2003) revealed that social influence is
complex and subject to a wide range of contingent influences in technology acceptance decisions
and impacts individual behavior through compliance, internalization, and identification. Hebron
(2008) referred to social influence as the demographic characteristics associated with the user,
which was interrelated and influenced outcomes based on how, why, and to what extent the user
anticipated his own experience with new technology.
Wokke and Rodenrijs (2018) suggested including social influence as a factor for the study
of factors affecting the consumer acceptance of cryptocurrency. Durr (2021) pointed out that
many current researchers also observed the lack of research on cryptocurrency, which poses
challenges for research and peer-reviewed works. Arias-Oliva et al. (2019), Kumari et al. (2023),
and Ramón-Rodríguez (2021) conducted research on how social influence affects blockchain
adoption. AlShamsi et al. (2022) mentioned that social influence is a significant determinant of
blockchain applications. This variable is measured using a 7-point Likert scale.
Several studies (Arias-Oliva et al., 2019; Carlin et al., 2017; Carpreau, 2023; Nuryyev et
al., 2018; Van Rooij et al., 2011) have shown that the following research variables influence the
acceptance of financial technologies. These research variables can be considered in future
research to study how these factors impact the adoption of blockchain technology. Performance
expectancy, effort expectancy, social influence, and enabling circumstances are the four
determinants of users’ behavioral intention in the Unified Theory of Acceptance and Use of
Technology (Venkatesh et al., 2003).
Performance expectancy is the degree to which a person considers using a specific
technology to enhance his performance (Venkatesh et al., 2003). Arias-Oliva et al. (2019)
demonstrated that performance expectancy determinant variable for the intention to use
cryptocurrencies.
Effort expectancy is defined as the degree of ease associated with the use of a specific
technology (Venkatesh et al., 2003). Effort expectancy is an intrinsic factor, like Perceived Ease
of Use and Complexity (Carpreau, 2023). Effort expectancy has been shown to positively
influence the consumers’ intention to use contactless payments, and this can assist in optimizing
the user experience for all types of technology users (Carpreau, 2023).
Facilitating conditions are the degree to which a person believes they have the required
organizational and technical infrastructure to use a specific technology (Venkatesh et al., 2003).
Facilitating conditions refer to the objective factors within the environment that observers agree
will enable certain behaviors to be performed with ease (Triandis, 1979). Triandis (1979) stated
that facilitating conditions directly affect the actual behavior instead of the intentions, as one may
have the intention to perform a particular behavior, but if the environment does not support this
behavior, then it will probably not be executed.
Perceived risk is defined as consumers’ perception of the degree of uncertainty and
possible undesirable consequences of using or buying a product (Arias-Oliva et al., 2019).
Perceived risk has been considered a determinant of technology adoption (Arias-Oliva et al.,
2019). Perceived risk is a critical variable influencing consumers' behavior toward using a
product (Kannungo & Jain, 2004). According to Nuryyev et al. (2018), perceived risk is one of
the three most essential factors in using cryptocurrency. Brown and Douglass (2020) conducted
a study on the costs of cryptocurrencies over three days when news of cryptocurrency thefts was
published and concluded that cryptocurrency prices rose after the robbery report, which showed
that Cryptocurrency theft has a significant effect on the price of cryptocurrencies. N. Liu and Ye
(2021) mentioned that trust is a determinant factor when engaging with one another using
blockchain technology via applications or websites.
Financial literacy affects a person's economic decision-making. Research studies show
that financial knowledge is an essential predictive factor in financial behaviors (Van Rooij et al.,
2011). Financial Literacy is defined as the knowledge of basic economic and financial concepts
and the ability to utilize that knowledge and other financial skills to manage financial resources
effectively for a lifetime of financial well-being (Stolper & Walter, 2017). Life expectancy and
financial literacy are important factors that influence the adoption of technology (Carlin et al.,
2017). Financial literacy has a more significant impact on the use of financial products or
instruments; as cryptocurrency is considered a technological financial instrument, financial
literacy is one of the research variables that influence the adoption of the technology (Carlin et
al., 2017).
Summary
The literature review chapter provided a detailed overview of Blockchain technology, its
applications, cryptocurrencies, and factors affecting blockchain-based cryptocurrency adoption.
The literature review contained the theoretical frameworks of the technology acceptance model
(TAM), the unified theory of acceptance and use of technology (UTAUT), and the diffusion of
innovations (DOI) to study the intention to use new technologies. The literature review showed
the significance of studying different factors influencing the adoption of blockchain technology.
The research study also included information about the previously conducted studies with their
research methodologies, sampling procedures, theoretical frameworks, and data analysis methods
used in these studies.
The literature review chapter findings thoroughly supported the research topic, research
gaps, and the selection of the theoretical framework used in this study. Moreover, the literature
review presented various current research studies in blockchain technology and provided
valuable suggestions for future research. Additionally, the literature review offered a good picture
of the research designs used to evaluate the adoption of new technologies.
Chapter Two provided a detailed review of the literature and the theoretical frameworks
associated with this study. A critical analysis of theoretical and empirical literature revealed a
literature gap in users' adoption of blockchain-based cryptocurrencies. Furthermore, the
literature review provided a direction to build a theoretical framework to guide this study.
Hypotheses were developed to examine how specific factors affect the adoption of
cryptocurrencies. Based on the theoretical framework and research hypotheses, a conceptual
technology acceptance model was generated for this non-experimental quantitative research
design. Chapter Three contains the research design, methodology, sampling procedures, data
collection, and data analysis using statistical methods.
Chapter Three
Procedures and Methodology
Introduction
Chapter Three presented the research methodology employed in answering the research
questions and testing the hypotheses for this study about the impact of various factors mentioned
on the adoption of blockchain-based cryptocurrencies. This non-experimental quantitative study
with a predictive correlation approach examined the influence of perceived usefulness, perceived
ease of use, compatibility, complexity, and social influence on the adoption of blockchain-based
cryptocurrencies. The researcher administered an online survey and used a random sampling
technique to collect participants’ data. Chapter Three illustrated the research paradigm, research
design, sampling procedures, instrument details, data collection, and statistical analysis for the
research.
Research Paradigm
Creswell and Creswell (2018) described the research approaches as the plans and
procedures for research that span the steps from broad assumptions to detailed data collection,
analysis, and interpretation methods. The research approach would rely on how the researchers
think about the problem and how it can be studied so that the results are helpful in a particular
discipline (Chilisa & Kawulich, 2012). Schwandt (2001) defines a paradigm as a shared
worldview representing beliefs and values in a specific field and guiding how problems are
solved. A paradigm represents a particular way of thinking shared by a scientific community in
solving issues in their areas (Kuhn, 1974). A paradigm is the commitments, beliefs, values,
methods, outlooks, and so forth shared across a specific discipline (Schwandt, 2001, p. 183).
Creswell and Creswell (2018) explained that there are three main frameworks for
research: Philosophical worldviews, Research Designs, and Research Methods. Creswell and
Creswell (2018) highlighted four different research paradigms: (a) Postpositivist, (b)
Constructivism, (c) Transformative, and (d) Pragmatism. The postpositivist research paradigm
assists in assessing the causes that influence outcomes in experiments and is mainly used in
quantitative research (Creswell & Creswell, 2018).
The constructivist approach, primarily used in qualitative research, focuses on the specific
contexts in which people live and work to understand the historical and cultural settings of the
participants and replies as much as possible to the participants’ views of the situation being
studied (Creswell & Creswell, 2018). Transformative paradigm aims toward the research where
research inquiry needs to be intertwined with politics and a political change agenda to confront
social oppression (Creswell & Creswell, 2018). Lastly, the pragmatic paradigm is more
frequently used in mixed methods research, where quantitative and qualitative research concepts
focus on actions, situations, and consequences rather than antecedent conditions (Creswell &
Creswell, 2018). The transformative paradigm assists in destroying the myths about technology
and empowers people to change society radically (Chilisa & Kawulich, 2012). The researcher
used quantitative methods for this research study to test a theory or claim about the future of
blockchain-based cryptocurrencies. Surveys, experiments, and questionnaires are a few
quantitative methods used to get numerical data for a population's trends, attitudes, or opinions
(Khaldi, 2017).
The postpositivist paradigm intends to reduce the ideas into a small, discrete set to test the
variables that comprise hypotheses and research questions by developing numeric measures of
observations and studying the behavior of individuals, also by testing the theories that govern it
(Creswell & Creswell, 2018). The postpositivist paradigm begins with a theory, requires data
collection, which supports or refutes the theory, necessary revisions, and contains additional tests
(Creswell & Creswell, 2018). Determination, Reductionism, Empirical observation and
measurement, and Theory verification are the main characteristics of the postpositivist paradigm
(Creswell & Creswell, 2018).
This research aimed to determine the extent to which five constructs, perceived
usefulness, perceived ease of use, compatibility, complexity, and social influence, predict the
intention to adopt blockchain-based cryptocurrencies in the United States. The relationship
among variables was established, and research questions and hypotheses were posed for the
study. The postpositivist paradigm aligned with and was appropriate for the research study.
Research Design
Creswell and Creswell (2018) described research design as the procedures of inquiry.
Creswell and Creswell (2018) acknowledged three research designs: (a) qualitative, (b)
quantitative, and (c) mixed methods. It is a very critical task to decide the suitable research
design and a type of study within these three types (Creswell & Creswell, 2018). Creswell and
Creswell (2018) mentioned that quantitative research uses numbers rather than words and uses
closed-ended questions and responses. Qualitative research is framed in terms of using words and
open-ended questions and responses to explore and understand the meaning individuals or groups
ascribe to a social or human problem (Creswell & Creswell, 2018). Mixed methods involve
integrating qualitative and quantitative research and data in a research study (Creswell &
Creswell, 2018).
Creswell and Creswell (2018) mentioned that selecting a research approach depends on
the nature of the research problem or issue being addressed, the researchers’ personal
experiences, and the audiences for the study. Creswell and Creswell (2018) illustrated that if the
research problem requires the identification of factors that influence an outcome, the utility of an
intervention, or understanding the best predictors of an outcome, then a quantitative approach is
suitable. Creswell and Creswell (2018) explained that quantitative research is an approach for
testing objective theories by examining the relationship among variables, where these variables
can be measured using instruments and can be analyzed using statistical procedures. Creswell
and Creswell (2018) discussed two quantitative design approaches, surveys, and experiments,
where survey research provides a numeric description of the trends, attitudes, or opinions of a
population by studying a sample of the population, which includes cross-sectional and
longitudinal studies using questionnaires for data collection to collect data from a sample
population; In contrast, experimental research determines if a specific treatment influences an
outcome.
R. Li et al. (2017) used the non-experimental quantitative research design with a
predictive approach to identify the relationship between two or more variables using appropriate
statistical analysis. The correlation research design measures relationships between variables or
tests hypotheses about predictions discussed in the study (Zyphur & Pierides, 2017). Creswell
and Creswell (2018) revealed that an individual trained in technical, scientific writing, statistics,
and statistical computer programs and familiar with quantitative journals would most likely
choose the quantitative design while explaining how researchers’ training and experiences
influence the choice of the research approach. The study was designed to analyze the extent to
which five independent variables, PU, PEOU, COMPB, COMPX, and SI, that are measurable
and quantified, predict the intention to adopt Blockchain-based cryptocurrencies’; that’s why the
non-experimental quantitative with predictive correlation approach is a more appropriate
research design for the study.
Sampling Procedures and Data Collection Sources
The research’s target population consisted of individuals familiar with blockchain-based
cryptocurrencies who reside in the United States and must be at least 18 years older. Identifying
the recruiting method and the suitable participant for the dissertation is a critical task (Lunenburg
& Irby, 2008). Piedade (2018) stated that the estimated number of cryptocurrency users is
difficult to determine, and it is even difficult to estimate a value, as one of the most important
characteristics of cryptocurrencies is the anonymity they provide to their users. According to the
US Bureau of Census, more than 258 million people 18 years and older reside in the United
States (Bureau of Census, 2023). According to the Economic Well-Being of US Households in
2022 report published by the Board of Governors of The Federal Reserve System (2023), three
percent of adults used cryptocurrency for financial transactions in the United States. The
researcher can increase recruitment success by narrowing down the sampling parameters and
setting eligibility requirements for the participants in the early stages of the study design
(EllardGray et al., 2015). Coinbase, one of the biggest cryptocurrency exchange platforms,
conducted an online survey in the United States and found that 20% of Americans own
cryptocurrency, translating to approximately 52.3 million American adults owning
cryptocurrency in 2022. The researcher used SurveyMonkey’s Target Audience service to get
random sample data from the population.
Creswell and Creswell (2018) mentioned that random sampling is the sampling technique
where every individual in the population has an equal probability of being selected. Random
sampling techniques reduce the chances of bias in study results and increase the generalizability
of the results (Sanders et al., 2018). Determining the correct sample size is one of the critical
components of the research study (Daly & Bourke, 2008). Recruiting the whole population for
the research study is optional if a large representative sample can deliver information accurately
(Daly & Bourke, 2008). A balance is needed between using too many or too few subjects in the
model (Kelly et al., 2010). When sample sizes are too small, there’s the risk of not collecting
enough data to validate the research hypotheses. The result may show that variables aren’t
statistically significant when they might be. The researcher may miss the subjects whose answers
might change the outcome (Fowler & Lapp, 2019). On the contrary, it would take more time and
money if the sample size was too large, and large sample sizes don’t always guarantee the
accuracy of the result (Fowler & Lapp, 2019).
SurveyMonkey was presented with the inclusion criteria, such as users at least 18 years
old residing in the United States and familiar with blockchain-based cryptocurrencies. The
SurveyMonkey Target Audience service was used to get random sample data from the
participants, and there was no interaction with the participants. The SurveyMonkey Audience
allows one to easily select and purchase a target audience based on specific attributes. The
SurveyMonkey Audience represents a diverse online population that voluntarily joined a
program to take surveys. The SurveyMonkey target audience service showed that 205 people
were qualified and contacted for participation, and 141 participants completed the survey
successfully. The basic census was selected for age balancing, and for gender balancing, the
census option was chosen to ensure gender distribution in the results. All participants could close
or quit the survey at any time without determent. All the survey questions were required to be
answered to complete the survey successfully. Multiple responses were turned off in the
SurveyMonkey collector settings to disable a survey from being taken multiple times from the
same device. To ensure all participants’ anonymity and privacy, the SurveyMonkey survey was
configured not to include the IP address of the respondent.
The power analysis for sample size determination should occur during the study planning
before enrolling any participants (Creswell & Creswell, 2018). The researcher used the G*Power
3.1.9.7 power analysis tool to calculate the correct sample size for the study. G*Power is a freely
available statistical power analysis tool to calculate effect sizes and display graphical results of
power analysis for many different tests (Faul et al., 2009).
The sample size mainly depends on population size, sampling confidence level, and
margin of error. The researcher used the G*Power analysis tool to determine the right
participants’ sample size with an effect size of f 2 0.15, a power confidence interval of 1-β error
probability = 0.95, and an error probability of α = 0.05.
A two-tailed alpha value (α) is called a Type I error rate, which refers to the risk
associated with saying that we have a real non-zero correlation when this effect is not real or a
false positive effect (Creswell & Creswell, 2018). A beta value (β), also called Type II error rate,
refers to the risk associated with saying that we do not have a significant effect when there is a
significant association or a false negative effect (Creswell & Creswell, 2018). The test family = F
tests, Statistical test of Linear multiple regression: Fixed model, R2 deviation from zero, and A
priori: Compute required sample size - given α, power, and effect size was selected for the type
of power analysis for G*Power analysis. The total number of predictors equal to five was
entered in G*Power input parameters.
Creswell and Creswell (2018) highlighted that it is important to clarify the statistical
significance testing, confidence intervals, and effective sizes while the results for the research
questions or hypotheses. Statistical significance testing assesses whether the observed scores
reflect a pattern other than chance (Creswell & Creswell, 2018). A confidence interval indicates a
range of values that describes a level of uncertainty around an estimated observed score or shows
how good an estimated score might be (Creswell & Creswell, 2018). An effect size is the strength
of the conclusions about group differences or the relationships among variables in a quantitative
study (Creswell & Creswell, 2018).
Villareal (2021) mentioned that if the power value is at least 0.90 or 90%, then
researchers can be confident about the power of the test to determine the effects with statistical
significance; the power value below 0.80 or 80% gives the sample size too small for the
generalization invalidating the experiment’s instrument. As per G*Power’s calculation, the level
of accuracy in predicting whether the null hypothesis should be accepted or rejected is 95%, with
a 5% margin of error. Field (2018) suggested that 0.95 is a commonly used power level for
quantitative studies as it shows that the chance of identifying an effect of independent variables
on dependent variables is 0.95%. As shown in Figure B1 in the appendix, the actual power in
output parameters will often be larger than the input power in a priori power analysis as
G*Power rounds the non-integer sample sizes to maintain the integer value. Based on the
G*Power calculation, 138 was obtained as the total minimum sample size for the research.
The short survey provides better data quality with higher response rates and less response
bias (Wang et al., 2020). Wokke and Rodenrijs (2018) acknowledged that the questionnaire
design for the survey should provide a clear explanation of the purpose of the study along with a
clear layout and design of each individual question should be clear. Furthermore, Wokke and
Rodenrijs (2018) added that the first step of questionnaire design is to look for existing items and
scale measures for each TAM construct to comply with the requirements to be reliable and
legitimate while adding questions to measure the proposed contribution to existing theory.
Creswell and Creswell (2018) mentioned that it is useful to relate the variables to the
specific questions or hypotheses on the instrument in the method section; However, the targeted
audience learns about the variable in purpose statements and research questions or hypotheses
sections. The researcher adopted the TAM measurement constructs, Perceived Usefulness (PU),
Perceived Ease of Use (PEOU), and Intention to Use (IU) from Arias-Oliva et al. (2019), Davis
(1985), Davis et al. (1989) and Kamble et al. (2021). The construct of Social Influence (SI) was
adopted from the UTAUT2 (Arias-Oliva et al., 2019; Venkatesh et al., 2012). The compatibility
(COMPB) and complexity (COMPX) constructs were adopted from Kamble et al. (2021).
The adapted TAM survey instrument used is provided in Appendix F. The online survey
hosted on SurveyMonkey consisted of mainly two sections. The first section had screening and
demographic questions about participants. The screening questions ensure the eligibility of
participants to participate in the survey instrument. The demographic questions aimed to collect
information about the geographical location, gender, and highest education level of the
participant. The second section of the survey instrument focused on measuring the constructs,
Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Compatibility (COMPB),
Complexity (COMPX), Social Influence (SI), and the intention to use (IU) blockchain-based
cryptocurrencies. The instrument used the Likert 7-point scale, where 1 = strongly disagree and
7=strongly agree, for measuring PU, PEOU, COMPB, COMPX, SI, and IU.
The validity and reliability of the instrument are vital factors that enable the research to
provide beneficial results; for this research, it is crucial to understand the measurement of the
reliability and validity of the instrument (Sürücü & MASLAKÇI, 2020). It is essential to
establish the validity of scores obtained from the past use of the instrument to use an existing
instrument (Creswell & Creswell, 2018). Validity represents whether the research correctly
measures what it intended to measure or how truthful the research results are (Golafshani, 2003).
Creswell and Creswell (2018) described three forms of validity: (a) Content validity, (b)
Predictive or Concurrent validity, and (c) Construct validity.
Content validity is the extent to which a research instrument accurately measures all
aspects of a construct (Heale & Twycross, 2015). Content validity provides details about whether
items measure the content they were intended to measure or not, Predictive or Concurrent
validity identifies whether scores predict a criterion measure or results correlate with other results
or not, and Construct validity assists in providing more information about whether items measure
hypothetical construct or concepts or not (Creswell & Creswell, 2018). Construct validity is the
extent to which a research instrument measures the intended construct (Heale &
Twycross, 2015).
Reliability is defined as the extent to which results are consistent over time and accurately
represent the total population under the study, which is referred to as reliability (Golafshani,
2003; Heale & Twycross, 2015). The instrument's reliability indicates whether scores resulting
from past use of the instrument demonstrate acceptable reliability (Creswell & Creswell, 2018).
Heale and Twycross (2015) described reliability as the consistency of a measure and outlined
Homogeneity, Stability, and Equivalence as the three attributes of reliability. Homogeneity is the
extent to which all the items on a scale measure one construct, Stability is the consistency of
results using an instrument with repeated testing, and Equivalence is the consistency among
responses of multiple users of an instrument or among alternate forms of an instrument (Heale &
Twycross, 2015). Different methods are used to determine the instrument's reliability for the
study; Still, the test-retest reliability, alternative forms, and internal consistency tests are the most
frequently used methods (Sürücü & MASLAKÇI, 2020).
Arias-Oliva M. et al. (2019) mentioned that to obtain a correct reliability indicator in the
measurement model, the standardized loadings of the variables should be greater than 0.7. The
most essential form of reliability for multi-item instruments is the instrument’s internal
consistency, which is the degree to which sets of items on an instrument behave in the same way
and is tested by Cronbach’s alpha value, which ranges between 0 and 1, with an optimal value
ranging between 0.7 and 0.9 (Creswell & Creswell, 2018; Heale & Twycross, 2015). A good
understanding of research bias helps readers critically and independently review the scientific
literature research, which could potentially be harmful. It is essential to understand the bias and
its effects on the study results (Pannucci & Wilkins, 2010).
Kamble et al. (2021) tested the validity and reliability of the measurement items using
various methods like exploratory factor analysis, composite scale reliability (CSR), and average
variance extraction (AVE). All the constructs measured in the instrument had factor loading
values higher than the threshold of 0.50 (Kamble et al., 2021). The CSR values were also above
the threshold value of 0.70, indicating an adequate internal consistency of the measurement items
(Kamble et al., 2021;). The discriminant validity of the instrument was tested using the squared
roots of the construct’s AVE (Kamble et al., 2021). Arias-Oliva M. et al. (2019) evaluated the
TAM model's reliability, convergent, and discriminant validity analyses. Arias-Oliva M. et al.
(2019) tested the AVE greater than or equal to 0.5, indicating that the convergent validity
criterion was met. All the constructs of TAM models had a composite reliability and Cronbach’s
alpha greater than the threshold value of 0.7, which indicates the construct reliability was
adequate (Arias-Oliva et al., 2019).
The conceptual and theoretical bias is caused by the researchers not creating a hypothesis
according to the literature and theoretical framework (Sürücü & MASLAKÇI, 2020). The sample
bias arises when the sample group included in the research does not represent the population
(Sürücü & MASLAKÇI, 2020). The measuring instrument used in the study is valid or reliable,
the expectation of validating the hypotheses, and the application of inappropriate analysis
methods performed in the statistical analysis are a few examples of transaction bias (Sürücü &
MASLAKÇI, 2020). The researcher should be aware of validity and reliability threats and take
appropriate measures to reduce bias in their studies to get beneficial results (Sürücü &
MASLAKÇI, 2020).
Statistical Tests
Multiple linear regression analysis was used in this study to determine the influence of
PU, PEOU, COMPB, COMPX, and SI on adopting blockchain-based cryptocurrencies. Multiple
linear regression is an excellent fit to predict an outcome variable (Dependent variable: IU) from
several predictor variables (Independent variables: PU, PEOU, COMPB, COMPX, and SI)
(Field, 2013). Multiple linear regression provides the R-value, the R2 value, the adjusted R2
value, and the F-statistic value to test the model.
R represents the multiple correlation coefficient between the predictors and the outcome
variable (Field, 2013). The value of R can be between -1 and 1; 1 indicates the perfect positive
correlation, and -1 shows the negative correlation (Field, 2013).
R2 is the squared correlation between the values of the outcome predicted by the model
and the values observed in the data (Field, 2013). R2 indicates the proportion of variance in the
outcome variable that is shared by the predictor variables (Field, 2013). The value of R2 can be
between 0 and 1; the higher value of R2 indicates the model's predictability is better (Field,
2013).
The adjusted R2 value explains how well the model generalizes (Field, 2013). If the value
of the R2 and the adjusted R2 are very similar, then it indicates that the cross-validity of the model
is very good (Field, 2013). The adjusted R2 value measures the loss of predictive power or
shrinkage in regression, which indicates how much variance in the outcome can be accounted for
if the model had been derived from the population from which the sample was taken (Field,
2013).
F-statistic represents how much the model has improved the prediction of the outcome
compared to the level of inaccuracy of the model (Field, 2013). F-statistics provide information
about how much variability the model can explain relative to how much it can’t explain, or
basically, it is the ratio of how good the model is compared to how bad it is (Field, 2013). If a
model is good, then the improvement in prediction from using the model should be significant,
and the difference between the model and the observed data should be smaller (Field, 2013). For
a good model, the F-statistic value is greater than one at least (Field, 2013).
Regression is commonly used for predictive analysis to predict a dependent outcome
variable from one or more independent predictor variables (Goss-Sampson, 2020). Regression
results in a hypothetical model of the relationship between the outcome and predictor variables
(Goss-Sampson, 2020).
Multiple regression analysis provides the opportunity to explore the relationship between
multiple independent variables and one dependent variable and the ability to identify how well a
set of variables can predict a particular outcome (Wokke & Rodenrijs, 2018). Multiple regression
analysis assists in discovering which variable is the best predictor of the dependent variable
(Wokke & Rodenrijs, 2018). Multiple regression allows groups of independent variables to be
compared with each other to see whether the overall fit of one model changes when more
independent variables are added (Wokke & Rodenrijs, 2018). Mertler and Vannatta (2016)
mentioned that the model summary table, ANOVA table, and coefficient table are the main
components of the multiple regression results. ANOVA (Analysis of variance) is a statistical
procedure that uses the F-ratio to test the overall model fit (Field, 2013). Field (2013) mentioned
that multiple regression is the same as simple regression, except there are two or more predictors,
and each predictor has its own coefficient. The outcome variable is predicted from a combination
of all the variables multiplied by their respective coefficients plus a residual term (Field, 2013).
Yi = (b0 + b1Xi1 + b2Xi2 + . . . + bnXn) + εi
Y is the outcome variable, b1 is the coefficient of the first predictor (X1), b2 is the
coefficient of the second predictor (X2), bn is the coefficient of the nth predictor (Xn), and εi is the
difference between the predicted and the observed value of Y for the ith participant (Field, 2013).
The multiple regression analysis was performed using the JASP statistical analysis tool,
and the Enter method was selected for the data entry. The model summary and ANOVA table
were used to determine the overall model fit for the study. The model summary provided
information about R, R2, and adjusted R2. The adjusted R2 showed the prediction of how
predictor variables could explain the variance in intent to adopt blockchain-based
cryptocurrencies. The ANOVA table presented the F-statistics and significance value, which
shows whether the model is significantly better at predicting the outcome than having no model
(Field, 2013). The significance value of p < 0.05 indicates that the predictor variable
significantly predicts the outcome variable (Field, 2013).
Arowolo (2017) used multiple regression analysis to test the relationship between six
technological and organizational factors to adopt cloud computing. Wokke and Rodenrijs (2018)
conducted a quantitative study to understand cryptocurrency consumer acceptance and analyze
collected survey data using multiple regression analysis. The statistical importance of every
identified variable is easier to analyze using the multiple regression method (Iftikhar et al., 2021).
Researchers widely use stepwise regression after conducting multiple regression analyses to
avoid misleading regression about the importance of variables (Iftikhar et al., 2021).
The multiple regression analysis requires testing several assumptions to draw conclusions
about a population based on a regression done on a sample (Field, 2013). The first assumption is
that all predictor variables must be quantitative or categorical, and the outcome variable must be
quantitative, continuous, and unbounded (Field, 2013). The second assumption is that all the
predictors should have some variation in their value or they do not have zero variances (Field,
2013). Other assumptions are the independence of observations, linear variable relationships,
Homoscedicity of residuals, no multicollinearity, no significant outliers, and normal residual
distribution, which are tested and described in more detail in the next chapter.
Table 2 outlines assumptions that validate multiple regression analysis (Field, 2018).
Independence of observation, linear variable relationships, homoscedasticity of residuals, no
multicollinearity, no significant outliers, and residuals being normally distributed are the
assumptions linked with the linear regression analysis (Field, 2018).

One of the multiple regression analysis assumptions is that the variables are independent
or not correlated (Field, 2018). The Durbin-Watson statistics test is used to determine the validity
of this assumption (Field, 2018). Field (2018) mentioned that the value of the Durbin-Watson test
closer to 2 indicates that the independence of observation exists or that the variables are not
correlated. A Durbin-Watson statistic test value of approximately 2 was obtained, which satisfies
the assumption of the independence of observation.

The mean values of the outcome variable for each increment of the predictors lie along a
straight line (Field, 2018). The outcome variable should be linearly related to all predictors to
meet the linearity assumption; if not, then the model is invalid (Field, 2018). The linearity
assumption is assessed using the scatterplot analysis to determine the validity of the assumption.

baseline, indicating a linear relationship between each independent variable and the dependent
variable. Figure B1 in Appendix B shows the plot of residuals of Intention to Use (IU) vs.

predicted values. Figure 8 shows that the residuals are randomly and evenly dispersed throughout
the plot, indicating that the assumption of linearity has been met.

Homoscedasticity is an assumption in regression analysis that the residuals at each level
of the predictor variables have similar variance, where variance is an estimate of average
variability or spread of a set of data (Field, 2018). Figure 8 shows the plot of residuals versus
predicted. The residual data points did not form the funnel shape or the curvilinear relationship.
The data points are randomly and evenly dispersed throughout the plot, indicating that the
assumption of homoscedasticity has been met. The balanced distribution of the residuals around
the baseline in Figure 8 shows that the assumption of homoscedasticity has not been violated
(Goss-Sampson, 2020).
When there is a strong correlation between two or more predictors in the regression
model, Multicollinearity exists (Field, 2009). Multicollinearity can be identified using the
variance inflation factor (VIF) as it indicates whether a predictor has a strong linear relationship
with the other predictor (Field, 2009). Bowerman and O’Connell (1992) suggested that if the
largest VIF value is greater than 10, there is cause for concern. Menard (2002) suggested that
values of tolerance below 0.1 indicate serious problems, and tolerance values below 0.2 indicate
a potential problem. Table 4 shows the results of collinearity diagnostics analysis using VIF and
tolerance values. Table 4 shows that the VIF values for the model are well below 10, and the
tolerance statistics are above 0.2, suggesting no collinearity within the data.

Outliners and high influence points were identified using the casewise diagnostics for
intention to use in JASP. Only one case had >3 standard residuals and was flagged as an outliner.
All cases had Cook’s distance less than 1, indicating no high influential points in the data.

The assumption of normality is important in research using multiple or general linear
regression models (Field, 2018). A P-P plot (probability-probability plot) is a useful graph to
determine if a distribution is normal. A P-P plot is a variable's cumulative probability against a
particular distribution's cumulative probability (Field, 2018). A Q-Q plot is very similar to a P-P
plot (Field, 2009). The P-P plot plots the quantiles of the data set instead of every individual point
in the data (Field, 2009). Figure 9 shows the Q-Q plot of standardized residuals. Figure 9 indicates
that the data points fall on the diagonal of the plot, which suggests normality. The Q-Q plot in
Figure 4 shows that the standardized residuals fit along the diagonal, suggesting that assumptions
of linearity and normality have not been violated (Goss-Sampson, 2020).

The third-party survey tool, SurveyMonkey, was used to host the survey and collect data
from the selected participants. SurveyMonkey used a random sampling technique to collect data
from different United States users. The SurveyMonkey assures data quality by providing features
like accurate targeting, panel calibration, survey design review, bot detection, and response
quality check.
Data collection was performed once permission was granted by the University of the
Cumberlands Institutional Review Board (IRB). All the study participants were provided with a
description of the study, the purpose of the study, the type of data collection, and any risk
involved in the informed consent form (Appendix C). Once the participants read and agreed to
the consent form, participants were provided with instrument questions. The instrument included
prescreening questions in the SurveyMonkey survey to ensure the quality of the data collection.
The prescreening questions aimed to confirm that participants were at least 18 years old, resided
in the United States, and knew about blockchain-based cryptocurrencies. After completing the
screening questions, participants had to answer a series of Likert-based instrument questions
ranging in scale from 1 (strongly disagree) to 7 (strongly agree) for various constructs.
Depending on the reliability of the survey responses from the participants, there are instances
where a 7-point scale may perform better than a 5-point scale, respective to the selection of the
items on the scale noted by the survey construct (Chang, 1994; Joshi et al., 2015). Also, a 7-point
scale gives more options that increase the chances of achieving the objective reality of
participants (Chang, 1994). The Likert scale's validity mainly depends on the applicability of the
given topic related to the participants and concluded by the researcher (Chang, 1994). Finally,
SurveyMonkey was set up not to collect any personal information about the participants,
including their IP address, to protect the anonymity of the participants.
The researcher needs to protect the privacy and confidentiality of all the participants
involved in a study (Creswell & Creswell, 2018). Anonymity and confidentiality are essential as
they protect the privacy of the research participants (Coffelt, 2017). No identifiable data was
collected from the participants for the research survey instrument. The Institutional Review
Board (IRB) of the University of the Cumberlands reviewed and approved the survey instrument.
The researcher provided informed consent at the beginning of the survey to learn more about the
research, the purpose of the study, and the survey. The researcher also presented a chance to
contact the researcher if the participants had any questions. The researcher allowed the
participants to leave or close the survey at any point. All the survey responses were downloaded
and copied to the encrypted drive. After three years, the researcher will delete the stored survey
data from the drive. All the collected data was only for scholarly purposes.
Confidentiality refers to modifying any personal or identifying information provided by
participants, whereas anonymity refers to obtaining data without personal or identifying
information (Coffelt, 2017). Participants learn about anonymity or confidentiality through the
informed consent document before participating in the study (Coffelt, 2017). Despite the best
efforts, when participants' private information is revealed, researchers must immediately notify
their institution’s IRB to protect the participants (Coffelt, 2017).
A considerable amount of effort was put into designing the survey and ensuring the
validity of the data collection. SurveyMonkey provides features like bot detection and response
quality checks for data validity. All the questions were set as mandatory to answer for the
SurveyMonkey survey, so all successfully completed responses were expected to have all the
survey questions answered. The researcher also reviewed all the responses for validity check for
the responses’ completeness. The researcher also looked for responses with the same answers for
all the Likert-scale questions, but none were found. The SurveyMonkey responses were imported
into JASP 0.16.4 statistical software for further analysis.
The survey instrument was administered on the third-party survey tool, The
SurveyMonkey. A total of 205 responses were received; however, 64 uncompleted responses
were identified and eliminated for the data analysis. A total of 141 responses were completed
successfully. The small sample size is one of the limitations of the study, which is not
generalizable to any other population. The statistical significance of PU, PEOU, COMPB,
COMPX, and SI on the intention to use blockchain-based cryptocurrencies was determined using
hypothesis testing. The researcher used JASP 0.16.4 to perform statistical analysis on the data
collection. The researcher downloaded the collected data from SurveyMonkey in CSV format.
The main aim of the data analysis was to test the hypotheses and test to what extent five
independent variables, PU, PEOU, COMPB, COMPX, and SI, influence the dependent variable
IU.
Descriptive Statistics was performed to review and validate the range for all questions.
The researcher examined the data for any missing data, although all the questions were
mandatory to answer. Creswell & Creswell (2018) mentioned that descriptive statistics analysis
contains the means, standard deviations, frequencies, and range of scores for all independent and
dependent variables in the study. Demographic data such as biological sex, age, educational
level, ethnicity, nationality, religion, socioeconomic status, educational attainment, or other
characteristics relevant to the study assist readers in obtaining a general understanding of study
participants and appraise how representative a sample is of a larger population (Coffelt, 2017).
Descriptive analysis for the demographic and instrument questions was assessed using
frequency, percentage, mean, and standard deviation. Table 6 shows the descriptive statistics of
the research variables.

Sürücü and MASLAKÇI (2020) stated that correctly structured hypotheses are the
indicator of which statistical analysis method to use and which of the variables will be dependent
and independent. The hypothesis testing technique was utilized in the quantitative study to
measure PU, PEOU, COMPB, COMPX, and SI’s statistical significance on the intention to use
the blockchain-based cryptocurrency. The researcher performed multiple regression analyses for
hypothesis testing, and a significance value of p < 0.5 and a confidence level of 95% was used
for the analysis to accept or reject the hypothesis. To test the blockchain-based cryptocurrencies’
adoption variance predicted by independent variables PU, PEOU, COMPB, COMPX, and SI, the
R-value, R2 value, and adjusted R2 value were utilized.
Multiple linear regression analysis was conducted using the JASP tool. Forced entry or
enter method was used, the default method in which all the predictors are forced into the
covariates box. The enter method is the best method for data entry (Goss-Sampson, 2020). Table

The adjusted R² used for multiple predictors shows that PU, PEOU, COMPB, COMPX, and SI
can predict 74.2% of the outcome variance or variance in the Intention to Use (IU)
blockchainbased cryptocurrencies.

A multiple linear regression analysis was used for hypotheses testing and to determine the
significance of the five independent variables: perceived usefulness (PU), perceived ease of use
(PEOU), compatibility (COMPB), complexity (COMPX), and social influence (SI) on the
dependent variable intention to use (IU). The research study used a significant value of p < 0.05
and a confidence level of 95% to test the hypothesis.
In this model summary, the value of the R2 shows how much of the variation in the
outcome variable can be predicted by the predictor variable of the model (Goss-Sampson, 2020).
The adjusted R2 shows how well the given model is generalized, and its value should be as close
to the value of R2 as possible (Field, 2018). Table 7 shows the difference between R2 and adjusted
R2, which is 0.010 (0.752– 0.742 = 0.010) or about 1%. The slight difference between R2 and
adjusted R2 indicates that the cross-validity of this model is very good (Field, 2018). This value
indicates that it would account for approximately 1% less variance in the outcome if the model
were derived from the population rather than a sample (Field, 2018). The F-test is used to
identify whether the model is significantly better at predicting the outcome than the mean
outcome (Field, 2018).
Summary
The focus of the study was to test the variables that comprise hypotheses and research
questions by the quantitative analysis, so the postpositivist paradigm aligned with and was
appropriate for the research study. The design of the quantitative study was non-experimental
with a predictive correlational approach, which was suitable for the study as there were five
dependent measurable variables: PU, PEOU, COMPB, COMPX, and SI, and one independent
measurable variable, ITU. A third-party survey tool, SurveyMonkey, was used to collect
participants' data. The collected data were analyzed using multiple regression analysis. Chapter
Three outlined the research paradigm, research design, population, sample, power analysis,
instrument, validity and reliability of the instrument, data collection, and statistical data analysis
method. Chapter Four presented a detailed statistical analysis of collected data and the research
findings. The statistical analysis assumptions were validated, and hypotheses were tested in the
next chapter.
Chapter Four
Research Findings
Introduction
The purpose of this nonexperimental predictive quantitative research study is to analyze
how the different variables like perceived usefulness (PU), perceived ease of use (PEOU), social
influence (SI), compatibility (COMPB), and complexity (COMPX) influence the intention to use
the blockchain-based cryptocurrencies. Chapter Four presented a study data report supported by
tables and figures.
In Chapter Four, the quantitative study results are presented and discussed on how the
perceived usefulness (PU), perceived ease of use (PEOU), social influence (SI), compatibility
(COMPB), and complexity (COMPX) impact the decision to adopt blockchain-based
cryptocurrencies. In addition, chapter four describes the sample and the hypothesis testing.
Furthermore, the collected data were reviewed and analyzed using the multiple regression
statistical analysis method. The summary of the hypothesis testing was demonstrated and
discussed. Finally, the reliability of each independent variable PU, PEOU, SI, COMPB, and
COMPX was assessed. At the end of chapter four, a summary of the analyzed preliminary
results is discussed with an interpretation of the findings.
Participants and Research Setting
The research conducted the participants’ recruitment via a third-party platform,
SurveyMonkey. The researcher utilized SurveyMonkey s service to get responses through
SurveyMonkey's audience using the target audience collector. The researcher targeted the
audience who knows blockchain technology and its application to cryptocurrencies. The
preinclusion questions in the instrumental survey ensure that the participants have basic
knowledge about cryptocurrencies, are at least 18 years old, and are in the United States of
America. The research study’s minimum number of participants was calculated using the
G*Power 3.1 analysis tool based on the statistical power of 95%, the effect size of 15%, and five
predictors. The minimum number of participants came out to be 138. The SurveyMonkey’s
incidence rate showed that 205 people were qualified, and 141 (n = 141) participants successfully
completed the online survey. The small sample size is one of the limitations of the study, which
is not generalizable to any other population. The survey results were exported in CSV format
from
SurveyMonkey and imported into JASP 0.16.4 for statistical analysis.
The participants’ demographic data were collected during the survey. The research study
participants’ descriptive information was 50.35% female and 49.65% male participants. The
participants’ gender distribution is shown in Table 10.

Participants’ educational background details were collected in the online survey
questionnaire. Participants' distribution by education is shown in Table 12. The participants’
distribution by education indicated that most participants either had a bachelor’s degree (n=35)
or were in some college but had no degree (n=35), approximately 24.8% in each category.
4.2% of participants had less than a high school degree (n=6), 22.7% had a high school degree or
equivalent (n=32), 12.8% had an associate degree (n=18), and 10.7% had a graduate degree
(n=15).

Analyses of Research Questions
After the data was collected from the participants, 205 responses were received. However,
26 uncompleted survey responses were identified, and 38 participants were disqualified as they
didn’t match the screen questions’ minimum criteria. Therefore, 64 survey responses were
eliminated from the data analysis. A total of 141 responses were valid for data analysis. The
minimum number of participants required for the research was 138. The hypothesis testing
method was used to identify the statistical significance of PU, PEOU, SI, COMPB, and COMPX
on the intention to use blockchain-based cryptocurrencies. The researcher used the JASP 0.16.4
tool to perform statistical analysis on the collected data set. JASP is an open-source project
supported by the University of Amsterdam. The researcher obtained the data set from the
SurveyMonkey third-party platform in an Excel spreadsheet. The main aim was to test the
hypothesis and examine to what extent the five independent variables (PU, PEOU, SI, COMPB,
and COMPX) influence the dependent variable (ITU).
SurveyMonkey’s exported Excel spreadsheet data was reviewed and validated as a sanity
check. All the survey questions were mandatory, so there wasn’t a need to identify any missing
data. The collected data were in the form of a seven-point Likert scale, scaling from 1 (strongly
disagree) to 7 (strongly agree) for the given survey question.
The hypotheses were using multiple linear regression to determine whether to accept or
reject the null hypotheses. The following are the study hypotheses:
H10. Perceived usefulness has no statistically significant influence on the decision to
adopt blockchain-based cryptocurrencies.
H1a. Perceived usefulness has a statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
BLOCKCHAIN-BASED CRYPTOCURRENCIES 98
H20. Perceived ease of use has no statistically significant influence on the decision to
adopt blockchain-based cryptocurrencies.
H2a. Perceived ease of use has a statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
H30. Compatibility has no statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
H3a. Compatibility has a statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
H40. Complexity has no statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
H4a. Complexity has a statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
H50. Social Influence has no statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
H5a. Social Influence has a statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
blockchain-based cryptocurrencies.
BLOCKCHAIN-BASED CRYPTOCURRENCIES 99
The multiple regression revealed that the
Research Question One
Research question one asked, to what extent does the perceived usefulness influence the
intention to use cryptocurrencies?
H10. Perceived usefulness has no statistically significant influence on the decision to
adopt blockchain-based cryptocurrencies.
H1a. Perceived usefulness has a statistically significant influence on the decision to adopt
perceived usefulness positively correlated with
the intention to use Blockchain-based cryptocurrencies (B = 0.701). Therefore, the greater the
perceived usefulness of cryptocurrencies at the user level, the greater the intention to use
cryptocurrencies. The p-value calculated for the perceived usefulness in the multiple regression
model was below the 0.001 significance level. Since the p-value < 0.05, the perceived usefulness
is statistically significant. In the regression equation, a change in the perceived usefulness is
expected to increase the adoption of Blockchain-based cryptocurrencies by a factor of 0.701
when other independent variables are kept constant.
The multiple regression model results showed that perceived usefulness (PU) was a
statistically significant predictor of intention to use Blockchain-based cryptocurrencies (β =
0.624, t (134) = 7.322, p < .05). The statistically significant result for perceived usefulness
showed that the null hypothesis H1o stating that the perceived usefulness has no statistically
blockchain-based cryptocurrencies.
BLOCKCHAIN-BASED CRYPTOCURRENCIES 100
The multiple regression revealed that the
significant influence on the decision to adopt blockchain-based cryptocurrencies is rejected at
95% confidence level. The alternative hypothesis H1a, stating that the perceived usefulness has a
statistically significant influence on the decision to adopt blockchain-based cryptocurrencies,
was accepted.
Research Question Two
Research question two asked, To what extent does perceived ease of use influence the
intention to use cryptocurrencies?
H20. Perceived ease of use has no statistically significant influence on the decision to
adopt blockchain-based cryptocurrencies.
H2a. Perceived ease of use has a statistically significant influence on the decision to adopt
perceived ease of use positively correlated with
the intention to use Blockchain-based cryptocurrencies (B = 0.282). Therefore, the greater the
perceived ease of use of cryptocurrencies at the user level, the greater the intention to use
cryptocurrencies. The p-value calculated for the perceived ease of use in the multiple regression
model was 0.028. Since the p-value < 0.05, the perceived ease of use is statistically significant.
In the regression equation, a change in the perceived ease of use is expected to increase the
adoption of Blockchain-based cryptocurrencies by a factor of 0.282 when other independent
variables are kept constant.
blockchain-based cryptocurrencies.
BLOCKCHAIN-BASED CRYPTOCURRENCIES 101
The multiple regression revealed that the
The multiple regression model results showed that perceived ease of use (PEOU) was a
statistically significant predictor of intention to use Blockchain-based cryptocurrencies (β =
0.181, t (134) = 2.224, p < .05). The statistically significant result for perceived ease of use
showed that the null hypothesis H1o stating that the perceived ease of use has no statistically
significant influence on the decision to adopt blockchain-based cryptocurrencies is rejected at
95% confidence level. The alternative hypothesis H1a, stating that the perceived ease of use has a
statistically significant influence on the decision to adopt blockchain-based cryptocurrencies,
was accepted.
Research Question Three
Research question three asked, to what extent does compatibility influence the intention
to use cryptocurrencies?
H30. Compatibility has no statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
H3a. Compatibility has a statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
compatibility negatively correlated with the
intention to use Blockchain-based cryptocurrencies (B = -0.084). Therefore, the greater the
compatibility of cryptocurrencies at the user level, the less the intention to use cryptocurrencies.
The p-value calculated for the compatibility in the multiple regression model was 0.514. Since
the p-value > 0.05, the compatibility is statistically insignificant. In the regression equation, a
change in the compatibility is expected to decrease the adoption of Blockchain-based
cryptocurrencies by a factor of 0.084 when other independent variables are kept constant.
The multiple regression model results showed that compatibility (COMPB) was not a
statistically significant predictor of intention to use Blockchain-based cryptocurrencies (β =
0.058, t (134) = -0.654, p > .05). The statistically significant result for compatibility showed that
the null hypothesis H1o stating that the compatibility has no statistically significant influence on
the decision to adopt blockchain-based cryptocurrencies is accepted at 95% confidence level.
The alternative hypothesis H1a, stating that compatibility has a statistically significant influence
on the decision to adopt blockchain-based cryptocurrencies, was rejected.
Research Question Four
Research question four asked, to what extent does the complexity influence the intention
to use cryptocurrencies?
H40. Complexity has no statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
H4a. Complexity has a statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
The multiple regression revealed that the complexity negatively correlated with the
intention to use Blockchain-based cryptocurrencies (B = -0.016). Therefore, the greater the
complexity of cryptocurrencies at the user level, the less the intention to use
cryptocurrencies. The p-value calculated for the complexity in the multiple regression
model was 0.811. Since the p-value > 0.05, the complexity is statistically insignificant. In
the regression equation, a change in the complexity is expected to decrease the adoption of
Blockchain-based cryptocurrencies by a factor of 0.016 when other independent variables
are kept constant.
The multiple regression model results showed that complexity (COMPX) was not a
statistically significant predictor of intention to use Blockchain-based cryptocurrencies (β =
0.010, t (134) = -0.239, p > .05). The statistically significant result for complexity showed that
the null hypothesis H1o stating that the complexity has no statistically significant influence on
the decision to adopt blockchain-based cryptocurrencies is accepted at 95% confidence level.
The alternative hypothesis H1a, stating that complexity has a statistically significant influence on
the decision to adopt blockchain-based cryptocurrencies, was rejected.
Research Question Five
Research question five asked, to what extent does Social Influence influence the intention
to use cryptocurrencies?
H50. Social Influence has no statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
H5a. Social Influence has a statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies.
The multiple regression revealed that social influence positively correlated with the
intention to use Blockchain-based cryptocurrencies (B = 0.186). Therefore, the greater the social
influence of cryptocurrencies at the user level, the greater the intention to use cryptocurrencies.
The p-value calculated for the social influence in the multiple regression model was 0.019. Since
the p-value < 0.05, the social influence is statistically significant. In the regression equation, a
change in the social influence is expected to increase the adoption of Blockchain-based
cryptocurrencies by a factor of 0.186 when other independent variables are kept constant.
The multiple regression model results showed that social influence (SI) was a statistically
significant predictor of intention to use Blockchain-based cryptocurrencies (β = 0.177, t (134) =
2.367, p < .05). The statistically significant result for social influence showed that the null
hypothesis H1o stating that social influence has no statistically significant influence on the
decision to adopt blockchain-based cryptocurrencies is rejected at 95% confidence level. The
alternative hypothesis H1a, stating that social influence has a statistically significant influence on
the decision to adopt blockchain-based cryptocurrencies, was accepted.
Multiple regression analysis was used to answer the research questions. Initially, multiple
linear regression models were assessed, including all the assumptions. Additionally, assumptions
like linearity, homoscedasticity, multicollinearity, and independence of observation were
evaluated. The results of the multicollinearity table, scatterplot, and Q-Q plot showed that all
those assumptions were met. The difference between R² and adjusted R² in Table 7 indicated that
the cross-validity of the model is very good.
The ANOVA (Analysis of Variance) table shows that the F-statistic is 81.071, p<0.05,
which indicates that the model is significant in predicting the outcome variable and that the
model is a significant fit to the data overall. The B-values for perceived usefulness (PU),
perceived ease of use (PEOU), and social influence (SI) indicated a positive relationship,
whereas compatibility (COMPB) and complexity (COMPX) indicated a negative relationship
between the predictors and the dependent variable. As shown in Table 13, the p-values for
Perceived Usefulness (β = 0.624, t (134) = 7.322, p < .05)., Perceived Ease of Use (β = 0.181, t
(134) = 2.224, p < .05), and Social Influence (β = 0.177, t (134) = 2.367, p < .05) were
statistically significant to the predictors of Intention to Use (IU), so the null hypothesis for
research questions one, two, and five was rejected, and the alternative hypothesis was accepted.
Compatibility (β = -0.058, t (134) = -0.654, p > .05) and Complexity (β = -0.010, t (134) =
-
0.239, p > .05) were not statistically significant variables in predicting the intention to use
Blockchain-based cryptocurrencies, so the null hypothesis for research questions three and four
was accepted, and the alternative hypothesis was rejected.

Summary
Chapter Four presented the research findings using statistical analysis. The third-party
survey tool, SurveyMonkey, was used for the data collection. The multiple regression analysis
was used to analyze how perceived usefulness (PU), perceived ease of use (PEOU), social
influence (SI), compatibility (COMPB), and complexity (COMPX) influence the intention to use
blockchain-based cryptocurrencies. The statistical analysis tool, JASP 0.16.4, was utilized to
perform statistical analysis. All the assumptions for multiple regression statistical analysis were
validated before performing the regression analysis.
The model summary shown in Table 7 suggested that PU, PEOU, COMPB, COMPX,
and SI can predict 74.2% of the outcome variance or variance in the Intention to Use (IU)
blockchain-based cryptocurrencies. The F-statistic and p-value for ANOVA results indicated that
the model is statistically significant in predicting the outcome variable and is a significant fit to
data overall. The p-values indicated that PU, PEOU, and SI were statistically significant
predictors of ITU, whereas COMPB and COMPX were not statistically significant in predicting
IU cryptocurrencies. The summary of the results, discussion about the research findings, and
implications of the study are discussed in Chapter Five.

Summary, Discussion, and Implications
Introduction
This non-experimental quantitative correlational study is designed to identify how
predictor variables perceived usefulness (PU), perceived ease-of-use (PEOU),
compatibility
(COMPB), complexity (COMPX), and social influence (SI) influence the decision to adopt
Blockchain-based cryptocurrencies. Five research questions were developed to guide quantitative
research. An online survey was conducted to collect participants’ data. Multiple regression
analysis was performed on collected survey data to determine the significance of the predictor
variables on intention to adopt blockchain-based cryptocurrencies. Creswell and Creswell (2018)
stated that the discussion section about the implications of the results shows how these results are
consistent with, refute, or extend previous related studies in scientific literature. The impact of
the findings on practice and future research in the area is essential to the research study (Creswell
& Creswell, 2018).
Chapter Five contains detailed research findings, including a comprehensive analysis of
the practical assessment of research questions. This Chapter also addresses study limitations that
may have arisen during the study and outlines the implications of these findings for future
research in the field. Overall, this chapter provides a thorough summary of the study's key points
and offers valuable insights into the potential avenues for further exploration in this area.
Practical Assessment of Research Questions
More adequate knowledge about the factors influencing cryptocurrency adoption in the
United States (Owusu, 2022; Silva & Mira da Silva, 2022). As discussed in the literature review
in Chapter Two, current research on adopting blockchain technology is mainly focused on the
organizational level. The literature review in chapter two revealed an existing gap in the literature
examining factors affecting cryptocurrency adoption at the user level in the United
States. There are various empirical studies like, Albayati et al. (2020), Arias-Oliva et al. (2019),
Ghonimy (2021), Iftikhar et al. (2021), Kamble et al. (2021), Sohaib et al. (2019), Wokke and
Rodenrijs (2018) utilized single or combination frameworks from the Diffusion of Innovation
(DOI), the Theory of Planned Behavior (TPB), the Unified Theory of Acceptance and Use of
Technology (UTAUT), and the Technology Acceptance Model (TAM). However, the literature
review in chapter two revealed that no previous work was published on adopting cryptocurrency
using the technology acceptance model by extending DOI constructs.
In this quantitative study, five constructs, perceived usefulness (PU), perceived ease-
ofuse (PEOU), compatibility (COMPB), complexity (COMPX), and social influence (SI), were
tested for significance in adopting cryptocurrencies. Five research questions were designed to
test the significance of each of these five constructs. An online survey was conducted to collect
user-level data in the United States. Collected data was analyzed using multiple regression
analysis. The practical assessment of each of the research questions is presented in the following
section.
Research Question One
Perceived Usefulness (PU) is the degree to which an individual believes using a
particular system would enhance their job performance (Davis, 1993). Research question one
stated to what extent does the perceived usefulness influence the intention to use
cryptocurrencies? The null hypothesis of research question one said that Perceived usefulness
has no statistically significant influence on the decision to adopt blockchain-based
cryptocurrencies. The analysis of research question one revealed that perceived usefulness (B =
0.701, t (139) =7.32, p < 0.5) was a statistically significant predictor of the intention to adopt
Blockchain-based cryptocurrencies. The null hypothesis of research question one was rejected in
support of the alternative hypothesis, stating that Perceived usefulness has a statistically
significant influence on the decision to adopt blockchain-based cryptocurrencies.
Mendoza-Tello et al. (2018) showed that perceived usefulness is one of the most
influential factors in the intention to use cryptocurrencies for electronic payments. The study
analysis aligns with the studies of “Arias-Oliva et al. (2019)”, “Cai et al. (2023)”, “Ghonimy
(2021)”, “N. Liu and Ye (2021)”, and “Sohaib et al. (2019)” found Perceived Usefulness as a
statistically significant factor in Blockchain adoption.
The perceived usefulness was statistically significant and positively correlated to the
intention to adopt blockchain-based cryptocurrencies. The result of the study supported the
positive correlation findings for the perceived usefulness of Ghonimy (2021) and Sohaib et al.
(2019). Furthermore, Ghonimy (2021) and Sohaib et al. (2019) found that perceived usefulness
has a higher significant positive effect on cryptocurrency use intention than perceived ease of
use. The statistical significance and positive correlation of perceived usefulness in the research
results suggested that users believe using cryptocurrencies would improve productivity or
performance in their daily lives.
Research Question Two
Perceived Ease of Use (PEOU) is the degree to which the prospective user believes that
using a particular system would be free of physical and mental effort (Davis, 1993). Research
question two stated to what extent does the perceived ease of use influence the intention to use
cryptocurrencies? The null hypothesis of research question two said that perceived ease of use
has no statistically significant influence on the decision to adopt blockchain-based
cryptocurrencies. The analysis of research question two revealed that perceived ease of use (B =
0.282, t (139) = 2.22, p < 0.5) was a statistically significant predictor of the intention to adopt
Blockchain-based cryptocurrencies. The null hypothesis of research question two was rejected in
support of the alternative hypothesis, stating that perceived ease of use statistically influences the
decision to adopt blockchain-based cryptocurrencies.
The study results showed that the Perceived Ease of Use was statistically significant and
positively related to the intention to adopt Blockchain-based cryptocurrencies. The analysis
aligns with the studies of “Ghonimy (2021)” who found that perceived ease of use was a
statistically significant factor in Blockchain adoption. The adoption of Blockchain is positively
influenced by the perceived ease of use, as demonstrated by “N. Liu and Ye (2021)”, and
“Sohaib et al. (2019)”. The study participants are knowledgeable in blockchain technologies,
which could be a possible explanation as they find blockchain-based cryptocurrencies easy to
understand and use.
N. Liu and Ye (2021) mentioned that trust is a determinant factor when engaging with one
another. Most users experience blockchain technology via applications or websites; therefore, if
the blockchain technology companies or service providers guide users, which can reduce the
complexity and make the users feel that using blockchain is easy and straightforward, then the
user may perceive the system’s ease of use through getting the information they require and the
positive experience tends to increase the user’s level of trust in blockchain (N. Liu & Ye, 2021).
Research Question Three
Compatibility is the degree to which an innovation is perceived as consistent with the
existing values, past experiences, and needs of potential adopters (Rogers et al., 2014). The
compatibility of an innovation is positively related to the adoption rate of the new system or the
new technology (Rogers et al., 2014). Research question three stated to what extent compatibility
influences the intention to use cryptocurrencies. The null hypothesis of research question three
said that compatibility has no statistically significant influence on the decision to adopt
blockchain-based cryptocurrencies. The analysis of research question three revealed that the
compatibility (B = -0.084, t (139) = -0.65, p > 0.5) was not a statistically significant predictor of
the intention to adopt Blockchain-based cryptocurrencies. The null hypothesis of research
question three was retained or accepted.
The study results showed that compatibility was statistically insignificant and negatively
correlated with the intention to adopt blockchain-based cryptocurrencies. The study conducted
by Kamble et al. (2021) found compatibility to be a statistically significant factor in Blockchain
adoption, which differs from this study’s result. Kamble et al. (2021) stated that compatibility
issues with the existing system affect the adoption of blockchain technology, and the
compatibility of blockchain with existing technologies in organizations will improve its utility.
The study participants are knowledgeable in blockchain technologies and know that an alternate
traditional payment system exists, which could be a possible explanation as participants find
compatibility not a significant factor for adopting blockchain-based cryptocurrencies.
According to Kamble et al. (2021), the degree of compatibility between blockchain
technology and the existing technological architecture, processes, and practices plays a pivotal
role in determining the perceived usefulness of the former. The greater the alignment between
these elements, the higher the likelihood of blockchain technology being perceived as useful. As
such, businesses and organizations should consider the existing technological infrastructure and
processes before implementing blockchain technology to ensure optimal compatibility and
enhanced efficiency. Arias-Oliva et al. (2019) suggested that the compatibility of a customer's
technology with cryptocurrency technical requirements is a crucial factor that could impact
cryptocurrency adoption, as the existence of widely accepted standards for different applications
with cryptocurrencies would be necessary.
Research Question Four
Complexity is the degree to which an innovation is perceived as relatively difficult to
understand and use (Rogers et al., 2014). The complexity of an innovation is negatively related
to the rate of adoption of innovation (Rogers et al., 2014). Research question four stated to what
extent complexity influences the intention to use cryptocurrencies. The null hypothesis of
research question four noted that the complexity has no statistically significant influence on the
decision to adopt blockchain-based cryptocurrencies. The analysis of research question four
revealed that the complexity (B = -0.016, t (139) = -0.24, p > 0.5) was not a statistically
significant predictor of the intention to adopt Blockchain-based cryptocurrencies. The null
hypothesis of research question four was retained or accepted.
Rogers’s (2010) Diffusion of Innovations Theory regarded complexity as a significant
determinant of innovation adoption. The result of this study refuted the significance of
complexity in Rogers’s (2010) Diffusion of Innovations Theory. The study results showed that
complexity was statistically insignificant and negatively correlated to adopting blockchain-based
cryptocurrencies. Complexity is inversely proportional to perceived ease of use and perceived
usefulness (Gangwar et al., 2015). The study analysis aligns with the studies of “N. Liu and Ye
(2021)” who found that complexity was not statistically significant in Blockchain
adoption.
However, the result differs from “Hashimy et al. (2023)”, which found complexity statistically
significant in Blockchain adoption. The study participants are knowledgeable in blockchain
technologies, which could be a possible explanation as participants find blockchain-based
cryptocurrencies easy to understand and use. N. Liu and Ye (2021) mentioned that blockchain
technology companies could reduce the complexity by guiding their users, providing a positive
experience, and helping to increase its adoption.
Research Question Five
Social influence is the extent to which consumers perceive that essential others, like their
family and friends, believe that they should use the new technology (Venkatesh et al., 2003).
According to UTAUT, social influence is one of the factors that influences behavioral intention
to use technology (Venkatesh et al., 2012). Research question five stated to what extent does
Social Influence influence the intention to use cryptocurrencies? The null hypothesis of research
question five said that social influence has no statistically significant influence on the decision
to adopt blockchain-based cryptocurrencies. The analysis of research question five revealed that
the social influence (B = 0.186, t (139) = 2.37, p < 0.5) was a statistically significant predictor of
the intention to adopt Blockchain-based cryptocurrencies. The null hypothesis of research
question five was rejected in support of the alternative hypothesis stating that social influence
statistically significantly influences the decision to adopt blockchain-based cryptocurrencies.
Albayati et al. (2020) proposed the technology acceptance model with new external
variables such as trust, regulatory support, social influence, design, and experience. Venkatesh et
al. (2003) mentioned that Social Influence constructs matter, and they are significant when used
in mandated contexts compared to voluntary contexts. Social Influence impacts an individual’s
behavior through compliance, internalization, and identification (Venkatesh et al., 2003).
The study results showed that Social Influence was statistically significant and positively
correlated with the intention to adopt blockchain-based cryptocurrencies. The study analysis
aligns with the studies of “Kumari et al. (2023)” who found that Social Influence is a statistically
significant factor in blockchain adoption. However, the result differs from “Arias-Oliva et al.
(2019)” and “Ramón-Rodríguez (2021)” results, which found that Social Influence was not
statistically significant in Blockchain adoption. The participants of the study are knowledgeable
in blockchain technologies. Organizations can utilize Social Influence to promote the advantages
of cryptocurrencies and can strategize to leverage Social Influence by promoting
cryptocurrencies or related services on Web 3.0 and Web 2.0-based social media networks where
choices of important ones can influence users (Kumari et al., 2023).
Limitations of the Study
The research limitations are often related to the study methods, which include inadequate
sample size and difficulty in recruitment, and they indicate areas for improvement in the research
that the researcher acknowledges so that future studies will prevent the same problems (Creswell
& Creswell, 2018). Several limitations were found while conducting this study, besides some of
the limitations mentioned in Chapter One. The research is quantitative and utilizes hypothesis,
but it might need to include contextual details, which assist in better understanding the results.
Quantitative analysis aims to analyze data and measure quantifiable variables. However, it is
essential to note that the characteristics of individuals who participated in the study may not
necessarily represent the general population (Ghonimy, 2021). Furthermore, the researcher used
the third-party tool SurveyMonkey to conduct an online survey, and its service, SurveyMonkey
audience, was used to recruit the participants for the study. The SurveyMonkey audience consists
of a diverse online population that voluntarily joined a program to take surveys. The researcher
relied on SurveyMonkey’s guarantee of recruiting participants that matched the inclusion
criteria. The research study was limited to the consumer acceptance of cryptocurrency. The
online survey was conducted for the participants who reside in the United States, which could
limit the generalizability of the research and data outside the United States; surveying different
countries or regions might yield different results.
The SurveyMonkey might have incentivized the SurveyMonkey audience to participate
in the study, so some participants might participate only to get incentives, not to contribute to the
study. It was not possible to validate the truthfulness of the participants' responses.
Another limitation of the study was the online survey design, where the close-ended nature of the
demographic questions might have prevented an opportunity to collect more information about
the research participants. Likert scales for this quantitative study might have limited the inclusion
of the participants’ opinions, experiences, and suggestions for improvement. A qualitative or
mixed-methodology research design would assist in capturing this information from the
participants.
Blockchain is comparatively the latest technology; although cryptocurrency has received
a lot of attention, there needs to be more knowledge and interest in the cryptocurrency topic
among consumers (Wokke & Rodenrijs, 2018). It is important to note that a potential limitation
of the study is the possibility that some participants may have limited knowledge of blockchain
technology and cryptocurrency, which could potentially impact the accuracy and quality of the
data collected during the research. It is therefore recommended to take measures to ensure that
participants are adequately informed and educated about the subject matter prior to their
participation.
The potential limitation of the study lies in its generalizability. While the sample size
obtained using a power analysis tool is considered adequate, it may not be sufficient for
capturing the larger population's diversity and variability. To improve the study's generalizability,
a larger sample size could be considered, which would provide more representative and reliable
data.
Implications for Future Study
The main aim of this study was to examine factors affecting cryptocurrency adoption.
Creswell and Creswell (2018) mentioned that it is essential to acknowledge the implications of
the findings for practice and future research. It is helpful to discuss the theoretical and practical
consequences of the results and highlight the potential alternative explanations for the research
findings (Creswell & Creswell, 2018).
Ghonimy (2021) stated that it is vital for organizations to understand the factors
that might influence the decision to adopt the new technologies. This study provides a
better understanding of the factors influencing the decision to adopt Blockchain-based
cryptocurrencies. Furthermore, examining the factors influencing the decision to adopt
new technologies assists in deciding whether to use certain technologies, as it paves the
path to a smooth transition to replacing old and new technologies (Ghonimy, 2021).
The findings of this research contribute to investigating factors affecting the adoption of
blockchain-based cryptocurrencies. The study presents several beneficial results but has a few
limitations that provide future research opportunities in this field. While this research was
conducted using a quantitative approach, future studies should consider utilizing a qualitative or
mixed-methods approach to gain a deeper understanding of the factors affecting cryptocurrency
adoption. Qualitative and mixed-method research approaches can provide rich and
contextualized data to complement and enhance quantitative research findings. Qualitative and
mixed-methods research can assist in capturing the perspectives and experiences of the
participants, which can reveal new insights and generate new hypotheses. Therefore, future
studies should adopt a more holistic and comprehensive approach to research by incorporating
qualitative and mixed-method research approaches.
Summary
This quantitative study aimed to determine the factors influencing the adoption of
cryptocurrencies in the United States using a predictive correlation approach. The study
considered five independent variables: perceived usefulness (PU), perceived ease-of-use
(PEOU), compatibility (COMPB), complexity (COMPX), and social influence (SI), while the
dependent variable was the intention to use (ITU) cryptocurrencies. Five research questions were
developed to test the significance of each of these five constructs.
An extensive literature review examined the foundational knowledge about blockchain
technology and current research on cryptocurrency adoption. Empirical studies in
blockchainbased cryptocurrencies were scarce, and a gap in the literature on the factors affecting
cryptocurrency adoption was identified. A survey was conducted on a population of
cryptocurrency consumers in the United States using SurveyMonkey, and the collected data were
analyzed using multiple regression analysis in JASP. The hypotheses were tested, and statistical
analysis assumptions were validated. The perceived usefulness, perceived ease of use, and social
influence were statistically significant predictors, whereas compatibility and complexity were not
statistically significant predictors of cryptocurrency adoption. This study has contributed a great
deal to the understanding of blockchain technology and the adoption of cryptocurrencies. The
findings of this study will be helpful for policymakers, decentralized autonomous organizations,
and developers interested in studying and improving the infrastructure for implementing
cryptocurrencies, aiming to increase their adoption in the future. The study also discussed the
implications for future research and provided recommendations for further studies.
