Yes, Investors play an important role in making the market up and down but there are many factors which no one can tell like covid came in 2020 and after that the price of bitcoin rise up and then went down then this Who's doing it all? Can anyone tell? I want to know

You want to know "who controls" the course of history.. A very philosophical question.
Did Napoleon "control" the outcome of the Napoleonic wars? He surely tried.. but failed.
Also in the Bitcoin Market.. Humans try to control everything.. but fail miserably.. most of the time.. Some manage to control niches.. then they become "Bill Gates".. Until he cheated on Melinda and got caught.
Puns aside.. no-one controls anything in the BTC Market.. It is a free market, albeit an illiquid one which reflects the fair price between demand and supply for a scarce item like BITCOIN.
