Whether Bitcoin existed or not, the Dollar will end the Dollar's reign. 
Fiat currencies don't last forever. They can't. With all debt-based money, eventual failure is an integral part of the recipe. It's just how they function. Some last longer than others, but they will all approach worthless at some point.

This is true, but as long as America is going strong its currency will continue to reign. It will last longer than any other fiat currency. Knowing Bitcoin's largest market is America, we can possibly say that Bitcoin might go along with the dollars reign and possibly go beyond dollar since its an international currency. Bitcoin can reach anywhere as long as there is internet. There is no limit unlike dollar which is limited to the growth of america.
