I think at this point the new trend is "decentralized finance". ICOs are over. DeFi is the new trend. If you Google "DeFi" you will see the trend yourself. DeFi is all about decentralized exchange, peer to peer derivatives, stable tokens which pay interest or even compound interest, decentralized lending where you can lend money and collect interest or borrow money etc.

Compound interest grows a lot slower than what people saw with ICOs but it's low risk and over time you will become rich from it if you simply reinvest your gains over and over.
