Neither bitcoin nor paper money has any real value, but notes have national credit support, and what if bitcoin also gets national credit? The government will lose its macro-control policy but it can also effectively eliminate inflation, two relative ratios. Is that a good result? Of course, I know that the government is very unlikely to support bitcoin, but who knows?
this is just my imagination, the economy in the country will be chaotic If the government supports bitcoin instead of the existing currency, but it will be stable if the government in the area issues their own country cryptocurrency.
That is why no government will ever decide to abandon its national money and use cryptocurrency instead. It would be disastrous for the economy of such a state. Therefore, an integral attribute of every independent state is the presence of national money. As long as various states exist, their national money will exist until then.
