Apart from scam artists in crypto space we have too many unprofessional developers that falsely act like they are really good in a particular field and try to build blockchain based projects but failed in the end,if there is really any way to make blockchain available to only professionals that are qualified it would have been a different story for crypto,even scammers wont have a chance,this is why i think we need REGULATIONS pretty bad.
Many people will be against state regulation of the crypto market. It's like hackers giving the green light to assigning them regular numbers.
If you want to avoid scammers, it is better to come up with your own internal checks that new projects will have to go through, and this will help reduce the risk of fraud.
