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.
I am sure that in the crypto market it is possible to skillfully combine regulation during the various rounds of ICO and IEO in order to protect investors from scammers. At the same time, do not allow regulation for trade, mining and other areas of the crypto market. With the wise use of regulation for the crypto market, it can be beneficial not to amend freedom.
