Exchanges do not want to crash, which is why they need market makers, and retail investors provide liquidity. From the perspective of the exchange, their task is to maintain market balance, so that those who want to buy can buy, and those who want to sell can easily sell, and then they happily collect transaction fees; this is their core purpose. They do not want the market to crash; without market makers, those who want to buy cannot buy, and those who want to sell cannot sell, rendering the exchange's functionality useless, and no one will come to play. Therefore, the 1011 incident may have involved the exchange itself taking over the coins and then slowly selling them over several months.
