Core Insights - The cryptocurrency market experienced a significant crash on October 11, with major cryptocurrencies like BTC and ETH dropping over 10%, while many altcoins saw declines of up to 90%. The total liquidation amount across the market reached approximately $19 billion, with more reasonable estimates suggesting it could be between $30 billion to $40 billion [2][5][6] - A notable event was the "de-pegging" of the stablecoin USDe, issued by Ethena, which fell from $1 to $0.65 on Binance, leading to widespread liquidations of margin accounts that used USDe as collateral [2][8] - The incident has raised questions about the risk management practices of centralized exchanges and the mechanisms behind stablecoins, particularly in extreme market conditions [3][10] Market Impact - The crash on October 11 is considered the largest and most severe single-day liquidation event in the history of the cryptocurrency market, surpassing previous events like "312" and "519" [5][6] - The impact was felt differently across market participants, with retail investors experiencing significant losses, while institutional investors reported manageable drawdowns, primarily due to their cautious asset selection and risk management practices [6][7] USDe Mechanism and Issues - USDe is described as a "synthetic dollar" rather than a traditional stablecoin, relying on a collateralized model where large institutional market makers provide volatile assets as collateral to mint USDe [11][12] - The mechanism involves staking collateralized assets to generate returns, but the high leverage and circular lending model associated with USDe contributed to its price collapse during the market downturn [15][16] Risk Management and Future Outlook - The incident has highlighted the need for improved risk management practices within centralized exchanges, particularly regarding the treatment of new and less liquid assets like USDe [32][33] - Ethena's future strategy may involve transitioning to a fully compliant fiat-backed stablecoin model within three years, as mandated by U.S. regulations, while also maintaining a separate business line for its carry trade strategy [22][24] - The market is expected to face challenges as liquidity conditions change, with a potential shift towards more short-term speculative behavior among investors [37][38]

Risk Control & Systemic Issues - Binance's internal risk control system has significant issues, particularly regarding the management of circulating loans for assets like USDe, WBETH, and BNSOL [1] - The de-pegging of WBETH and BNSOL, assets that should be redeemable 1:1, highlights flaws in Binance's risk management [1] - The market's reliance on Binance's pricing creates systemic risk, as other exchanges and market makers are overly confident in Binance's stability [1] - The lack of immediate action or a post-incident report by Binance following the liquidations is unreasonable [1] Binance's Responsibility & Accountability - Binance should be held accountable for the volatility caused by assets that rely on its reputation, such as WBETH and BNSOL [1] - The issues leading to the liquidations should have been addressed six months prior, suggesting a failure to learn from past events like the FDUSD incident [1] - The author questions whether temporary control or suspension of trading for abnormal assets could have mitigated losses during the liquidation event [1] Market Impact & Solutions - The market impact of Binance's issues is greater than historical de-pegging events like USDC during the Silicon Valley Bank collapse [1] - The industry needs better solutions to address the current situation, rather than engaging in meaningless emotional venting [2] - Individual users should learn from this event, improve their risk management, and protect their capital [2]

Core Viewpoint - The recent market turmoil in the cryptocurrency sector was primarily driven by macroeconomic factors rather than systemic failures of Binance, despite the platform experiencing technical issues during the crash [1][3][4]. Group 1: Market Events - The market downturn began on a Friday, triggered by U.S. President Trump's tariff threat, leading Bitcoin to drop 13.5% from a peak of over $126,000 [3]. - During this period, users reported significant issues on Binance, including system delays and account freezes, exacerbating their losses [3][9].

Group 3: Asset Decoupling and Allegations - There were speculations about a targeted attack on Binance's Unified Margin system, which allows users to use multiple assets as collateral, potentially leading to a collapse in collateral values [4]. - Binance refuted claims that asset decoupling was the cause of the market crash, stating that the market drop occurred before significant asset decoupling [4]. Group 4: Technical Issues and User Concerns - Users expressed concerns over sudden price drops of tokens like ATOM and IOTX, which were perceived as market manipulation [6]. - Binance explained that these price drops were due to a lack of buy orders and the triggering of historical limit orders set at very low prices, not actual price collapses [6]. - The platform also addressed user interface issues that led to misleading price displays, promising to optimize and correct these problems [6].
