The one people least expected
The President of China Xi Jinping
It is undeniable that in the end China could be one of the good options but in the end with the characteristics of their country which is more closed and a little contrary to the ideology they are taking for now then I think this will be the last possibility to happen because after all it does not mean to weaken but they will still uphold what they have done since the beginning where transparency of each citizen's income and equalizing conditions for each citizen is always a priority. By trying in bitcoin and introducing this just like the US did then indeed they will erode the ideology that they have upheld since the beginning and that is clearly difficult to happen.
But when it comes to economic conditions and including political elements in it then all things can happen but if in the end Xi Jinping does that and without any obstacles from his decision then in the end the same situation could happen even though I don't expect such a thing because for me it will make a little bit of the assumption that bitcoin will only be able to be like now thanks to the help of a few people who raised it alone but the fact is certainly not like that.
