I don't think so. Us dollar is an international and very established money. To many countries (to not tell almost all) have their reserves in their Central Banks mostly in us dollar. Has almost the status of gold. Bitcoin has the qualities of being reserve money (is uninflationable) but I think that it is insufficient to fulfill the requests of all the countries.
So it is very difficult to replace the dollar in the near future, when the system is well established ie dollars, while bitcoin is still a lot of things to be studied and studied for example is the number of unfinished transaction confirmations.
