Great advice, but most people take advantage of the DeFi hype for quick profit. Therefore, many people are still interested in new projects. Even though they know the huge risk of investing in such a system, people will still do it.
Fast profits can only be obtained by those who invested in the beginning of the Hype DeFi, after that it no longer exists, even for now there are already some investors who have lost through investing in the DeFi project.
for the start of defi coins, there are indeed many who get big profits, but for now in my opinion there are not many who are profitable, because defi coins that are bought always experience a decrease in contrast to the initial appearance of defi coins, many people experience losses because of coin def, maybe because only a little coin defi which is serious about developing its project
Early investors to only make profit are what you see in the project/investment that are hype and this is a viewpoint the OP don't understand before he listed some Defi projects which gained investors attention through the influential status of the team involved cause the last time i searched all Defi project are hype base.
