I think it still takes time, when the world is screwed up, the threat of war Korea vs. USA make the economic recession, and could not be disputed that the influence of the USD is still very strong that bitcoin it took a long time.
Thats what happens when you hungry for power but that has nothing to do with bitcoin becoming a global currency because its a decentralized and not controlled by either of the two countries.
Of course politics might have an impact on the future of bitcoin but atm its doing pretty fine to be recognized as a Global Currency.
