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
Personally, it is more likely to happen and its completely suitable for these two currency to coexist and serve for our demand. Because as we all know that we are living in advanced technology era, digital currency is such a mainstream which represents for the world of technology. Both fiat and crypto currency bring us benefit. Although almost all governments impose a ban on crypto, its still accepted by some countries and some big business gradually. Moreover, people seem so much keen on using bitcoin for paying for commodities or services and the like. Compare to Fiat, bitcoin is just on the earlier stage, but still goes forward. Many people from various places of the world aspire to use bitcoin officially. Thus, if we can use both Fiat and Cryptocurrency for payment, its such a great thing that make many people feel satisfied.
