I would like to know if cryptocurrency will replace fiat money in the future, also if so how long it will likely take. Also, I would like to know which coin you think would take over if one will. (E.G. Dogecoin, BTG, LTC, XMR)
Fiat is used much more widely has a much higher supply and will forver be an important part of the concept of money . It is unlikely for crypto to replace fiat albeit it can comprise as the major part of the currency system. Laymen are yet to be educated upon crypto so until we see a widespread development in technology fiat cannot be forgotten.
