It is a point that if a country would used crypto as means of currency then it could be controlled by the evil mafia... Thus, how could we say the fiat (money) right now. Is it being controlled by the this evil mafia too. Crypto is not the purpose for destruction, even things are not meant for destruction. People tend to destroy. Thus, if we would established new things without any security, then it would end to be used in evil manner. We made because we want improvements and it is not meant to destroy or alter things.
