Why did Zhuang crash during the decline? You buy to provide liquidity and smash the market. If you provide more opponent disks, smash the disks. If you open a short position, you only need a small rebound to sell it out, especially if Meme is listed on the exchange, it can easily rebound by dozens of points during the decline and then continue to fall. How should we deal with the coins that are on the decline of spot and contract prices on the exchange? Not buying spot goods, not opening too much or too short, without liquidity, without competitors, the market would not be so arrogant.
