There are many efforts to move away from the U.S. dollar throughout the world, but it has been very difficult to do so. The reason why the U.S. dollar is so dominant is because the U.S. has the largest military and very deep and sophisticated financial markets. We are seeing China and Russia buy gold and consider making a digital currency. More than likely, other nations will follow, including those of the Middle East. I doubt any newly-issued tokens will replace the U.S. dollar if major governments have had a hard time doing so. Anyway, I hope this is done in good-faith.

I think bitcoin has the best shot among cryptocurrencies to replace the U.S. dollar!
