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.
Regulation in the crypto market for conducting ICO and IEO would be good, it would help reduce the number of cheaters among new projects. The only problem is that there is no general opinion on the crypto market regarding regulation, and there is no definition in choosing an organization that could regulate and catch scammers.
