To date, the economic situation in many countries is in critical condition. Can the next financial and economic crisis be a transition to global use of crypto currency in international settlements?
Well, it all depends on the country. If a country really does depend on the global trade then if you are among this people then you can just make crypto as the transition for you to transfer your savings into it.
you're right, the country can move it to cryptocurrency but I think it's dangerous for the economy because I think cryptocurrency prices can change at any time (fluctuations)
