What should be discussed again and indeed in this world there is no single currency and every country has their own currency with the system they built themselves for the progress of the country's economy, for cryptocurrency itself I think there are still many people who do not understand this technology and there , Many regions are lagging behind in terms of technological progress, Bitcoin still needs a lot of time to be recognized evenly throughout the world, Fiat is still the best now for each country and crypto is still largely an investment vehicle for future inventories.
