I know it may not be possible right now, but do you think fiat will be gone in the future?
Yes it's not possible to replace fiat currency, since from very long time people are using fiat money, digital currency means only for purchasing through onlie,in many places digital currency not accepted.
No i dont believe that digital currency will replace fiat because its price is unstable and there some people are still dont know about it. And i think all government would not allowed to used it replace as currency.
