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.
I dont think it can be anytime soon. But I still prefer using the National Currency since it is the legit tender. You eaen in BTC and convert to your national currenncy, that would be beneficial.
