I've seen that most of the DeFi project doesn't turn out great unfortunately I wasn't able to invest at least to 1 DeFi since I think this could be risky, so where the DeFi headed to? We're not quite sure at all maybe soon we would be able to have something new.
The bubble of DEFIs created in 2020-2021 seems to be bursting now and Investors are huge losses but I still believe it is not not a failed idea it should work because we all need handsome passive income beside active to meet rising expenses of daily life. The idea is great but it has to be monitored by regulatory authority to make it less risky, protect it from scammers. The 2nd issue is your funds are not insured in case of any theft and exit scam. In my opinion centralized platforms have better future because they have better functionality and properly secured though it contradicts with the idea of De-centralization.
