My thought is this: None of the above nor anyone else has the capacity to harm Bitcoin. Of course they could try to and maybe succeed in causing some depraciation in bitcoin's value in the short-term, but it is far beyond any one entity to completely take Bitcoin down to its knees, especially at this point. Look, there are far more people in Bitcoin than you can ever imagine. They (we the bitcoiners) are full of knowledge and wisdom, not of fiat but of reality. The fiat world is full of foolishness and short-term thinking, and lacks moral standing. To fully grasp Bitcoin, you have to see it as a self-sovereign technology and self-custody money. Whatever means Elon, Jack, or BlackRock might want to implement in order to undermine Bitcoin has already been tried and failed. The only possible way to harm Bitcoin is to kill every single node in the universe. Good luck with that.
