It's a good list, but mind you that many of the investors interested in this DeFi hype aren't doing any painstaking research to find the scam projects, most of the DeFi tokens are pump, dump or fake coins, imo, most of this investors are already aware of the risks in DeFi, but atm, it's all about the hype and pumped ROI that they can get from it, I don't even think there's a need to warn investors about DeFi anymore, users who are investing in it feel they can handle the risk, not that they are unaware of it.
Got some earning on these and loses too but of course its risky.
Imo, the people who could lose out the most in this DeFi hype are people who consider holding DeFi tokens for the long run, DeFi investors should always take out their ROI when they get them, with all the scams going on, DeFi doesn't look set to last too long.
