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.
I am also suggesting an industry-wide self-regulation wherein a platform can be established manned by people who are into the blockchain and cryptocurrency that can help vet on different projects, platforms, products, services in making sure that they adhere to the standards that the industry will itself established. This in addition to limited regulations that the government will have to do and in case of a proven scam prosecution in the courts of law. Scamming will always be here as long as we are dealing with human beings as proven with our own human history...what we can do is make sure they are minimized to the very least possible.
