As long as there are people who are investing in projects because of money without doing due diligence on reviewing the team and the legitimacy of the project people will use cryptocurrency to scam people. Scanners opt to create new altcoins since they know there are a lot of investors who are greedy and easily attracted in projects promising good returns.
I don't understand that discontentment because of scammers in crypto.
Yes it is bad and we should fight against them. But people look around - scammers are everywhere and I bet there are a lot more scammers in fiat than in crypto, since it is way easier to hide profit in cash rather than in blockchain
Be patient and pay attention to what you are investing in
