Money laundering started in fiat, I dont understand why fiat is not banned. I feel that the governments are not able to control crypto currencies like fiat, hence some countries dont allow it.
Of course goverment will not ban fiat money because from fiat goverment take a lot income tax. Yes goverment cant control crypto, that why he make bad issue about bitcoin to convince people that bitcoin is bad, This is big agenda for something big. The funny is, goverment dont ban ripple, like my county all crypto is banned but ripple dont, why ?? Centralized.
