I don’t think that we can actually avoid 100% in all scams in crypto. I have encountered a lot of projects wherein they really have potential, good community, and yet end up being a scam at all. Though I think we can minimize the risk of not getting scam at all times. So you have to do a thorough research at all times especially if you plan to invest a huge amount of your money.
It is indeed impossible to avoid a scam project because doing research on the project is also not a guarantee that it will avoid being scammed,
however research is still important before joining the project,
what is certain is that the scam project is really troubling so we have to be extra careful
