I am talking about bitcoin, not whatever markets you are talking about. Banks and hedge funds break laws all the time and get fined for it. They rehypothecate gold, the short sell equities without borrowing the underlying, and so on.
Everyone's trying to make a buck. But imagining that a group of people are somehow suppressing the price of bitcoin, which is the most free and open market in the history of human civilization, suggests you don't really understand how the markets work.
Tell me, if you would, exactly how "they" are suppressing the price of bitcoin?
