If Bitcoin becomes the world reserve currency, won't it become a self fulfilling phenomenon? That action would devalue all other fiat currencies, thus stabilizing Bitcoin and assuring its future use and value. What might major global sovereigns do to prevent that? What could they do?
It's hard for me to imagine any sovereign, especially China, being trusted to hold a world reserve crypto currency denominated in their fiat monetary units.
Bitcoin will not become the world's reserve currency. No government would allow a private citizen to create a reserve currency anymore than they would go back to a gold standard (as much as some want that). The Fed and other central banks are working on their own digital currency. I think we will have one in the next 10-20 years or so.
