Countries now are thoughtfull about cryptocurrencies and are somewhat cautious, at least how they bring the news and how they regulate cryptocurrencies, I dont blaim them yet because the market is very young and they stil not have decided what to do with cryptocurrencies, in the end it will benefit them but many people think cryptocurrencies will replace fiat, let me tell you know that that is not possible in any way for another 50 years at least, the reason I am saying this is because all the wars, trade wars etc. etc. is all because of keeping your country powerfull and stable, the governments will do everything in order to keep their fiat safe.
