This may happen. But bitcoin is not always approved by governments,
and we can not say that all governments in the world want bitcoin.
So bitcoin can be a global power, but not in all countries
What makes bitcoin a world currency is not because it has been accepted through out the world but because 1. It is the most accepted, other altcoin are still looking forward to bitcoin. What makes the US election have influence on bitcoin value is not because of the president's personality but because of the position of America herself in the world power and economy. Irrespective of whosoever won, bitcoin has s still highly valued anywhere,anytime.
