Lets say crypto completely and utterly replaced fiat. Fiats don't exist anymore. All governments have seen the advantage of using digital currency and have completely changed their fiat into crypto, like dollar to dollar token(obviously not tether). How viable is this? For example anyone can see how much I am holding using the public ledger and track me down and force me into sending them the cryptos I hold. I wanna discuss in reality if cryptos actually replace fiat how life will be and what are the problems we are gonna face and the immediate effects of it.
In this current era, it is not yet possible because government will not let the cryptocurrency to replace fiat. The government are aware that they can't control the cryptocurrencies becuase of the characteristics of being decentralize and volatile.
