While some nations such as China and India have cracked down a lot on crypto, others like Japan have become much more risk averse and want to protect users, while some such as the US seem to be generally embracing it. From what I hear, a number of politicians already own bitcoin, so hopefully that number continues to rise to disincentivize them from legislating such counterrevolutionary moves... but I do think that the most devious thing nation states could be doing is working to pit us against each other in order to distract us and slow down the pace of innovation.
