I have no doubts about the fact that the Dollar will win from the Bitcoin because the bitcoin is still too small and the Dollar is way to big to get defeated.
What people also are saying is true the bitcoin is a sort of depending on it.
Yes and it always have been proved by its price. We always use the USD as a means of telling how much it is. It is the most populae currency that is why it is more used. The strength of USD came from its value, many countries use it also as a means of telling the price of a thing if it is a foreigner who is transacting. Even if he holds EURO.
