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.
The problem is the safety of our account, i believe when crypto replace fiat it means the value will be more stable and the transaction could be fast as fast using debit card. But the security of our account is so vunerable, or maybe there will be a wallet that cant be hacked.
