Currently, there are many usd-based stablecoins such as, usdt, busd, usdc and maybe many others. To be honest, I used to think that crypto would completely eliminate the usd's dominance of the world economy but I was wrong, it turns out that usd is now evolving to crypto (stablecoins). What do you think, whether in the future bitcoin or other crypto can replace the role of currency in each country and leave fiat currencies such as usd, euro, yuan and others.
That would be unlikely. Both crypto and fiat can coexist as they have different real use case functions. Fiat cannot be replaced and is here to stay. Crypto can be used as alternative payment option for goods and services. Yes USDT is a stablecoin, but it’s still a cryptocurrency.
True, although the volume of crypto transactions continues to increase and currently reaches more than $ 140 billion per day but I'm sure it will never replace the function of fiat, maybe the influence of fiat will continue to decrease and switch to crypto but I believe fiat will always exist and last forever.
