I want it but seems it will never happened that fiat are established since hundreds years ago and government already make fiat as one of the economy tools but although crypto came with several features which possibly to beat fiat but government will always be attempts to eleminate crypto from people life but indeed if fiat can collaborated with crypto i think most people will feel the benefit from it
Countries who accepted or those who did not legalized nor banned cryptocurrency feels the benifit of the both, using cryptocurrency and fiat, they are both benificial in a way that sometimes they are competing with one another. I said so because the characteristics of fiat can be done by the cryptocurrency and crypto is much more improve and impressive than fiat.
