to my knowledge, some of the reasons or factor of the bitcoin price is from the trading or the investor who controls or who has the most profit in the market, they certainly do the game for their own profit in terms of trading, as far as I know they make a bitcoin purchase from the offer of all people after they master all that they definitely win in terms of lowering the price of bitcoin, from that they started playing in terms of buying bitcoin from the offer of very low people.
