if all switch to virtual currency, then what about real money conditions whether each country will stop making real money in the future I don't think so ... !!?
I don't think that everyone is turning to virtual money because if all use virtual money, the value will actually decline.
I think fiat will continue to be used for payment in traditional markets not on the global market. Every country community still respects their fiat in accordance with the provisions that apply in their country of residence.
