While it is difficult to predict something about this, since the situation around the cryptocurrency is changing very quickly. Anything can be. But it is too early to draw definite conclusions. First, cryptocurrency must firmly enter our life and it is necessary that states develop a more or less unified attitude towards it.
So far, I have little faith in the fact that states will use bitcoin or any other decentralized cryptocurrency as a global reserve currency. With the advent of a significant number of digitized state currencies, and especially regional digitized state currencies, the likelihood of such use will decrease even more.
