Such popularity of DeFi projects is not surprising. Many people have managed to make big money by investing in various DeFi projects. Now this is probably one of the few areas in the crypto world where you can make money.
However, one cannot say that investing in DeFi projects is a 100% guarantee of income ... there are risks ... and the risks are huge. I still prefer to combine investment in DeFi with trading on exchanges. Moreover, the Coinsbit exchange is ideal for these purposes.
