It is estimated that 51% of Bitcoin users are outside of the United States, so the idea of separating global currency from the U.S. is feasible. Several countries and thousands of vendors are already accepting Bitcoin technology as a form of payment, which means this adoption of payment will only grow.
49% users in United States? Not at all. Give us a source please.
I remember some of USA agencies showed up the percentage of bitcoin users around the globe according to the percentage, and USA was having like 25% of total users, not 50%.
