Aside from the fact that bitcoin is a hedge against inflation in times like this for people living in that region, I don't see what difference it will make. It's not like they can use bitcoin I their day-to-day activities, or people fleeing the country can spend their bitcoin without changing them to fiat.
They can also receive bitcoin from loved ones abroad, but they need to exchange it to their local currency because I doubt they will be able to spend the bitcoin like that.
You mean that Bitcoin cannot be used because users from countries at war move to other countries must exchange it into fiat, then use it. Is that so?
Isn't there something in every country that allows citizens to withdraw in the form of global currency?
What I know, on the binance exchange for each user can do BTC/Fiat pairs. There is EUR and some other pairs. It seems like it can be done.
Beyond that, this is important for every country to enforce Bitcoin as a currency that can be accepted as payment even though it is not the main currency.
