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.
Well indeed many people have thought or predicted about this, but here we see that ordinary currencies have absolutely become the hallmark of each country, which I think will be difficult to be replaced by new currencies, such as cryptocurrencies that only exist in the internet (not in physical form), where people must first need an internet connection.
This will be complement only, due to its advantages that so far has been proven to provide to push the human financial side.
