Personally, big countries like China, the US or Russia are better off being neutral than having a share, because what I see is that countries like that will always look at it from a profit standpoint and control it from within. Therefore, if the position is neutral crypto growth will be much more stable without the interference of big powers. Maybe some of us see it when countries like China and the US are crypto-friendly to have a big impact on adoption? may be true but the US and China have a much broader goal which is to control every financial transaction entering every exchange at any time if it is to pass regulation. That is what we need to fear, not only from the positive side but the negative side where anonymity has completely disappeared.
