Some time ago, it was mentioned that the open interest in the Sol contract market hit a record high, and some big dealers were ready to manipulate the market. Recently, the market has undergone a large liquidation. As can be seen in the figure, the open interest has basically returned to zero. Moreover, it is not only Sol, but also Bitcoin and Ethereum have been liquidated simultaneously. It seems that the big dealers behind the scenes have made a lot of money, and the people who took over are the people who posted about their margin calls on social media. So I don’t think the market crash was caused by news, but a purposeful and precise surgical slaughter. It is a pure game behavior in the market. Contracts are like this. When the open interest reaches a certain level, one party will definitely be liquidated in large quantities, and the margin calls will be linked together. The margin call price points between traders are connected, just like lighting firecrackers, and the price will not stop until the liquidation is completed.
