Yes, right, maybe this is the reason why many parties refuse crypto. It would be dangerous for a country if the country makes crypto as a currency, if crypto is very easy to manipulate, then a country that embraces crypto will be easily controlled by the evil mafia mafia.
You have the idea there fellow. It maybe dangerous too for the country if not properly studied and just use crypto currency. It really needs to be studied first and must plan some regulations so that it will not be used to destroy others.
