The scandal involving OKEx illegally withholding 517 BTC from a user has been exposed. According to the official announcement released by the OKX platform in 2023 regarding this matter, the facts are roughly as follows: In July 2018, Yang Xiuchun, a major investor, used his personal account to long on Bitcoin, opening approximately 50,000 long positions when the price was around 7,000 USDT. OKX unilaterally froze her account on suspicion of "market manipulation," preventing her from opening or closing positions. On the same day the account was frozen, she was liquidated due to market fluctuations. OKX characterized this liquidation as an abnormal margin call, which means that the account was wiped out before the liquidation price was reached. The customer still has 517 bitcoins in their wallet, and they haven't been allowed to withdraw them for eight years. According to Yang Chunxiu, the person involved, she was simply a bullish Bitcoin user who had been consistently long on the day of the incident. After being notified by OKX via phone that they might be involved in market manipulation, she agreed to start reducing her holdings. However, OKX didn't give her that chance, abruptly freezing her account and quickly liquidating a large portion of her holdings. With a position of 50,000 Bitcoins, such a rapid liquidation would only result in a margin call due to the drastic price fluctuations. Yang Xiuchun believes that this margin call could have been avoided. She also suspects that OKX deliberately locked all of her long positions under the pretext of risk control, and then used its own short positions to trade against her, wiping out all of her principal. (The official announcement stated that the sharp drop in BTC price ultimately led to the liquidation of her position. However, according to Yang Xiuchun's own summary, the actual situation was that OKex quickly liquidated her long positions, causing the price drop and resulting in the liquidation.) Afterwards, the remaining 517 bitcoins in Yang Xiuchun's wallet account were also frozen, and she has not been allowed to withdraw them for the past 8 years. The screenshot shows that OKX's official announcement only mentions the freezing and liquidation process, but makes no mention of the freezing itself. Yang Xiuchun's current demand is that the OKX platform come forward to give a complete account of the entire incident, provide her with an explanation, and clearly state the reason for unreasonably freezing her 517 bitcoins. The number of views on this matter has exceeded 1 million, and it's impossible for OKX to avoid it now, as it involves the credibility of a platform. Everyone is now waiting for OKX's latest response. We will continue to follow this big story!
