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, It's surely takes time before the crypto currency replace the national money. And it will go through many processes and discussions between the government and the citizens before it become national money in the country.
For sure, many citizens are going to rally to shout out there voice against it, because they can not afford to buy a new gadgets, they can not follow the innovation of the technology, they are lack in learning this cryptocurreny and also the poor people will loath to do it because of the level of their status.
Fiat is very important and it is become part of our daily life and I know lots people will fight for their rights in economy and against the cryptocurrency to became national money.
