Star Bridge Capital (SBCFX) investors say an abnormal liquidation incident in London gold trading on the evening of August 19 wiped out accounts after automated trading systems generated large reverse short positions within 1 to 3 seconds. International gold prices then rose rapidly, triggering collective liquidations; some accounts fell to zero or showed negative balances. An estimated 2,000 to 3,000 people were affected, including many mainland investors. Some have reported the matter to the Hong Kong police and are seeking a refund of 70% of their principal under the platform’s previously promised "maximum loss of 30%" rule. Investors also claim the platform offered leverage of up to 500 times, while some deposits were made in USDT stablecoins, potentially complicating fund tracing. Public information describes Star Bridge Capital as offering foreign exchange, commodities, indices and cryptocurrencies, and the platform claims to be licensed and compliant.
