I found this expression on the news channel about the crypto currency: "Anyone who will try to buy coffee for cash in 2023, runs the risk of causing laughter from the seller, that he does not use crypto currency."
how do you think, is it realistic? Can a crypto currency replace national money?
I think that it's possible, but it will take more time.
Crypto will definitely constitute a large portion of the e currency market but will not be able to outtake the national currency as fiat will always have more credibility. Maybe of the woeld becines completely dependent in technology we can see such a change where fiat is not the primary currency.
