Maybe there will be certain groups of countries that will make bitcoin as super sovereign currency. Perhaps they will form and bond together to push bitcoin globally. But for sure it will be opposed by top countries, Dollar, Yuan will still be the standard to be used by global trades. They will argue against it as we all know that bitcoin is volatile and unstable and we only have limited supply. Bitcoin can grow tremendously, no doubt about it, but pushing to be a super sovereign currency? I highly doubt it for now.
