Again, to say it's backed by nothing is incorrect. It WAS backed by the confidence of all nations that it would be honored in trade. It WAS backed by the fact that if you wanted oil from SA, you would need to use Dollars. That's not "nothing." However with Oil Trade enforcement severed from the Dollar, it is now backed by just about nothing until they roll out their new Bretton Woods system. Also, there's a big difference between decentralized crytocurrency and a privately-controlled crytocurrency. By the way, Bitcoin's price is controlled. You think half a Trillion is libertarians using it? LOL
