although bitcoin has a high enough value but i think bitcoin isn't the world's strongest currency, because to my knowledge bitcoin is a virtual currency even though it has a function equivalent to fiat currency but illegal bitcoin legality
I still confuse how we can do research to maintain which one is the strongest currency in the world? What is the indicator? Price or use?
If price, yes i can say its the strongest one.
But if use, fiat money is still number 1.
