Help me find a research question for my paper

Hey there

I'm in my last year of High School and we need to write a paper by the end of the school year. I wanted to write about crypto but I'm not sure what is:

• explainable to teachers (they need to understand what I'm talking about)
• easy to find information on (my paper should consist of a minimum of 15 pages of pure text)
• an interesting category

​

I also love finance, so I was thinking DeFi, but I'm not sure if I can find enough information on it.
