This incident occurred in 2018. The user established an abnormally large long position in BTC within a short period using high leverage and refused to cooperate after the platform repeatedly requested "reduction of positions" based on risk control measures, significantly impacting market stability. According to the user agreement, the relevant account was frozen, and subsequently, due to excessive leverage and a drop in BTC price, the account was liquidated. If this market manipulation had not been stopped in time, it would have had a huge impact on all trading users. In this incident, the platform also allocated 2,500 BTC from its own funds to a risk reserve pool to mitigate the impact on other users. Subsequently, the platform has continuously optimized its risk control system through mechanisms such as price marking and position limits. As a centralized exchange, it bears the responsibility of trust and operation, and therefore has an obligation to protect users engaged in legitimate trading.
