in my opinion governments can and will adopt cryptocurrencies as protocols but not replace fiat currency.
fiat currency has its advantages that we dont consider, read the book Naked Money he talks about it there
fiat money is great, its the people who are not educated enough to use it wisely
I think, even though fiat money is good, but they also experience inflation, there is no promising fixed value. with cryptocurrency speeti. my suggestion is better the government divert to crypto to be used as the country's currency as a medium of exchange. so that people can easily conduct transactions in everyday life.
