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 ... !!?
in my opinion the real currency will not change function and value but will change shape along with the development of time and technology and may also adopt an economic system that uses crypto currencies
It is only a matter of time when real money will be replaced with digital money. Already, most transactions take place without cash. This is beneficial for governments from the point of view of financial control over the flow of money. So, we should expect a significant decrease in the role of real money in a short time.
