Thanks @fun2learn for this entry! I love how you describe DeFi as "online banks". I think you are largely right to say that. I also like that you pointed out that there are risks involved, like any kind of investments.
Just to point out that BlockFi and Crypto.com are centralized custodial solutions that allow users to earn interests on their cryptocurrencies. Strictly speaking, they are not DeFi. Some call them CeFi (centralized finance), some still categorize them as DeFi but it is right at the spectrum where almost everything is centralized.
Once again, thanks for your contest entry! Hope you don't mind if I cross-post this to the DeFi Campus community?
