This incident occurred in 2018, when the user established an unusually large long position in BTC within a short period through high leverage. After the platform repeatedly requested to "reduce positions" based on risk control, the user refused to cooperate, significantly impacting market stability. According to the user agreement, the relevant account was frozen, and subsequently, due to excessive leverage and the decline in BTC prices, it ultimately faced liquidation. If this market manipulation had not been promptly stopped at that time, it would have had a huge impact on all trading users. In this incident, the platform also injected 2,500 BTC from its own funds into the risk reserve pool to mitigate the impact on other users. Subsequently, the platform has been continuously optimizing its risk control system through mechanisms such as marking prices and position limits. As a centralized exchange that carries trust, it bears operational responsibilities and thus has an obligation to protect normal trading users. The announcement of the incident is as follows:
