i only know that bitcoin is not yet used in every country, real money is used by every country. bitcoin is from the online and real money is for offline. bitcoin can send it to every where without border, money needs to be convert when we want to send into other country.
Bitcoin is already used throughout the world, maybe, even more universally than the US dollar (I mean geographically, of course, not by the bulk value). "Real money", on the other hand, is real only for the given country, all other monies in this respect are not "real" since they are just foreign currencies. I guess only a few currencies could claim to be universal and not quite "foreign" to most countries. These are the American dollar, the Euro, and, to a lesser degree, the British pound and the Swiss franc...
And I'm heavily inclined to think that Bitcoin tends to belong to the these group of currencies
I am bored, have a nice day.
Just a few minutes ago you were "really interested" and now you are bored?
