The crypto backed by the gov't or by the banks. The known CBDC or Central Bank Digital Currency.
This is now the main thing in China lately and I think US and other powerful countries will also follow the trend for this. Once this has already been implemented in China and it's being used by most citizens, I think most of the countries that are looking into cryptocurrency will start to follow that path.
not all of them, and I think crypto supports its own digital currency, not including bitcoin and altcoin.
so your statement is a little wrong, the United States and other countries may be right they support crypto and that has been happening for a long time for America, and will only be implemented in other countries.
