Literature Review: Alternative investment opportunities in times of digitization

Hey guys,
I need your help for a literature review in the field of finance!

I thought about the following structure (I´m open for new ideas)

Overview of different investment opportunities / startegies:

1.1 In the past -> Gold, bonds real estate 

2.2 Today -> real estate, luxury goods or maybe cryptocurrency
2.3 Point of view of Banks -> due to low interest rates and his consequences 

2.4 How to cope with changing customer expectations -> Robo advisory 

8Pages high quality,  without frontage and literature. APA Guidelines,  100% plagiarism free.  Literature is required.

Thank you for your help
