Why do we need to replace the fiat with crypto currency anyway. The business of government is going good, there is no problem with their traditional financial system for which fiat is at most important things to have. Now, again the question is why do we really need to replace this fiat? Will government allows to do that or in any way will there be scope for this or not? I guess no, because its not needed and that will just create more mess around the world and nothing else. The point is, traditional fiat has not been made with simplicity but complex structure of central to local banking system and thousands of people working behind it. You think that accepting crypto will be as easy as cutting the pie.
