It's some kind of revolution, but be aware as we had many scam ICO's, we will have many DeFi scams too. It's how it goes, but we will have something good that will come out from this madness. Some DeFi projects are really good and they will survive in the long term, as we have some coins that started with ICO and now they are big. Just don't invest in any DeFi, do some research, and try to trust the top ones.
