No one actually knows about it , only crypto whales are the one who can dump it any time , if they want to pump they will till the end of 2021 , if they want to dump they can dump it anytime.
Although you are absolutely right, there is a point that you have not taken into account, emotions, when people feel strong emotions, they usually buy and buy, it may be that at that moment the whales are selling and at the same time we see that the price of Bitcoin continues going up, and it is because the market is also moved by emotions. Both the whales and the powers are what move the market.
And this has always been true, from the 1800s from the stock market to the Bitcoin market.
