  Dollar is powered by one of the biggest economical, political and military power in the world.

    The USD also had some difficult beginnings, and through luck and force of will has been established as the de-facto world currency. Saying that no-one will ever challenge the king is foolish, short-sighted, and naive.

      No one reasonable says that USD cannot be challenged. Chinese yuan is on the way there and we’ll see that fight pretty soon. Bitcoin is not even not in the same league - it’s playing different sport.
