Sure, any platform does this action, but it differs because they execute it with wallets not in their names so that the matter appears normal.

Two years ago, FTX was one of the largest cryptocurrency trading platforms in the world. Its beginning was promising, but behind the scenes, a very big game was being played on the market.$BNB
The story:
FTX would sometimes open huge positions on cryptocurrencies, for example, a bullish position 🟢, and start buying large quantities of a certain coin. As a result of the large purchase, the price would automatically rise because the market reacted to the volume of demand. After the price rises and attracts other investors, FTX opens a selling position 🟥 and sells the quantity it previously bought at a higher price, thus making a significant profit at the expense of other investors who entered at the wrong moment.
