Affirmative. DeFi is still an actual thing since it unlocks a lot of use cases for crypto. It's awesome that we have decentralized money, it's even more awesome that there would be decentralized products and services that we can use our decentralized monies to interact and actually get some value out.
Most DeFi projects are in lending area that is very unsustainable and risky. From DeFi 1.0 to DeFi 2.0, altcoin projects have good growths and attract big capital from investors who want to stake their coins, tokens and earn interests from DeFi platforms.
After two or three years, impermanent losses are worse and who bought those tokens in 2021 bull market, maintained to stake their tokens so far surely are living with fear and small hope to get their initial capital back. Those tokens drop a lot in value from UNI (Uniswap) to CAKE (Pancakeswap) and other smaller DeFi platforms, other DEXs' tokens.
