Drug dealers and people laundering money want fiat. How do you get fiat? Exchanges follow KYC and if you exchange in person your face and identity are seen. It's not as easy as it sounds. Does it happen? yeah of course, but people have money laundered in crazy ways.
The cryptographic market is a land of crime of tax evasion, money laundering, illicit trafficking, and lack of administrative authority. This easily leads to the collapse of a developing market. Money laundering is simple and is not investigated by any government authorities because of the great anonymity of crypto. Too many things to worry about this market
Nice argument.
