What if Satosi Nakamoto is just a fictional character behind whom there is a whole group of developers. I think that Bitcoin created a government of one of the countries (USA, China) to use this new industry further in its favor

That's what I thought too, that they are group of people but they are hiding their identity, what's the scariest thing that will happen is that if they are group of people and that is why they are hiding their selves identity is that the are planning something bigger that will shock the whole world and that is when the price of Bitcoin became $50k or more that they will sell it.
And in General, if in fact there is a group of people behind bitcoin, it is not clear what the purpose of their invention is?If the goals are clear-why then hide?It's a dilemma that makes me worry.
