You're awfully presumptuous.

The global economy functions with many, many different currencies, nearly all of which are managed by a central bank. It's widely accepted that currencies are best that which are regionally segmented, because the qualities and monetary needs of different economies tend to vary locally. See wikipedia on Optimal Currency Area.

Thus, we consider individual currencies on a case by case basis. By almost every conventional and widely-accepted measure, bitcoin is a terrible currency with little chance of remaining stable. a.) it's region agnostic b.) hugely speculative c.) inelastic, practically constant supply d.) difficult to centrally manage.

Please, tell me more about economic history.
