Of course, cryptocurrency will never replace the national money of states. The issue and circulation of money on the territory of the state is completely under the jurisdiction of the state power - the legislative body and the government, as well as the central bank of the country. This replacement is only possible through appropriate action by these bodies, as was the case in El Salvador.
Change is constant in this planet. Fiat money would be change in due time since today digital transfer is very possible wherever you are as long as the address is correct. What is the relation?
Everything will change including money from tangible to intangible value. If we bring back the history, goods matter than money. Not impossible for fiat and crypto. Tangible and intangible store of value. Technology is improving every day.
I agree with you, everything wil change at the time.
Your opinion is make sense.
Crypto currency wil replace fiat money at the digital era, becaue everything will be crypto at the coming future.
Digital currency will dominate at future.
But It will happen at the next several years again, maybe 7-10 years again. Not for the next few years.
As we know, everything is possible.
