For a long time, now the political elite and the leaders of the Vatican have been looking for a world government and currency,
I do believe that bitcoin is a part of financial future and great way to become an investor, but I have doubts that it can possibly replace traditional money or become world currency.
What are the possibilities and stopovers??
It can be, but not a standard one that would require all countries to use it as the "main" coin to be used in deals, payments, investments and the like. I think that it would be too hard for many countries who has established currencies to just give it up because it has proved its reliability, and also, it has a long history behind it that has made people put their trust on it just like the American Dollar. So, I more so foresee a time when currencies can interplay with cryptocurrencies much like the onset of the use of internet banking once the internet has been more far-reaching.
