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.
Yes, I think not. Bitcoin will not replace the national currency. I just imagine that in the future there is a digital currency but not Crypto. It's more like USD or other currencies in digital form. That's in my opinion.
