I don't think dollar would come to an end for another 50 years at least. Bitcoin is not that popular to take over.
Right now Bitcoin is not that popular but the Dollar will crash it should become more popular. The Dollar may not end soon but it will lose most its value as the number of Dollar in circulation increases and it becomes a smaller portion of exchanges and reserves in the world
True, but if people all around the world keep accepting dollars no matter how many are created out of thin air.. what can stop it anytime soon?
