When creating DeFi, they tried to take into account the mistakes of the ICO, and only time will tell the vulnerable sides of DeFi. But the worst thing is that it is impossible to get rid of scammers and hyped projects, they will still find ways to make money in any project, with any protection system.
This, at the beginning when icos were first introduced in the market we saw many good projects being developed and that is why that form of funding became popular, but what happened? Scammers noticed this and began to take advantage of people and it is exactly what it is going to happen to DeFi projects as well, the first DeFi projects were good and as such they generated profits, people wanted to be part of that and scammers obliged, so sooner or later all of this hype over DeFi projects will end.
