That's exactly why I created the DeFi scam list (DeFi-Scams - Big All-In-One-Thread - LAST UPDATE: 19/10/2020). Even if we're only able to detect a fraction of all DeFi scams out there, inexperienced users will get an idea how many DeFi scams and fakes are out there. And even if a certain project isn't a classic scam people will be more careful before investing their BTC.
If we want to protect inexperienced users from the dangers of the DeFi space, it's all about information. Only if people know that at least 98% of all projects in that space are classic scams, HYIPs or ponzis they won't fall for everything bullsh*t these scam developers are promising to them.
I wouldn't be so sure about this. Right now, the DeFi space is still comparably small, but you are right: If the hype continues inevitably more people will fall for new DeFi scams.
