People should understand that defi is not for long term investment where if you will participate in it then you should quickly exit because defi are prone to dumps and the data in the OP proving that many people are dumping their tokens after it got listed. I actually wanted to try to participate in defi but I will make sure first that the money that I will invest is the money that I can afford to lose because I really understand on how risky investing in Defi.
There are DeFi projects that are good for long term, you sound like all DeFi projects won't survive on the long run, is chainlink not a high quality crypto project and it's a DeFi project, there are many others like ChainLink, the issue here is investors want to make their gains from any available DeFi projects so they care less what the DeFi project is all about
