I agree with you. DeFi project seems the next potential tool to use by scammers effectively. Well, one of the ways to scam people effectively is by using what the most favorite ones currently. We must know that nowadays, most scammers prefer to use IEOs on small or unpopular exchanges to attract people than using ICOs. As most investors don't trust again in ICOs, scammers rarely used ICOs to trap people anymore. We must realize that scammers are always following the current trends in crypto to get the victims, so be more careful guys!!
