Bitcoin is now the sixth most circulated currency in the world, behind five super powers, and outranking the Pound, the Ruble, and the Won, according to the Bank for International Settlements. The figure is based on a value of Bitcoin at $10,765 each, meaning that the total value of all Bitcoins in circulation is $180 bln.
While the number is substantial, should Bitcoin rise to $15,000, it will overtake the next highest circulating currency, the Rupee. The other four currencies outranking Bitcoin are the Yen, Yuan, Euro, and Dollar, all of which have dramatically greater levels of currency in circulation (the Dollar, for example, stands at $1.4 tln).
