Hong Kong stocks extend their losing streak, with the Hang Seng Index falling below the 23,000-point threshold. Zhipu AI’s shares plunge over 9%, leading declines in the AI sector.

Circle CEO Jeremy Allaire told CNBC in an interview that he is not particularly focused on Bitcoin’s short-term price performance, instead expressing greater optimism for a digital dollar tailored for payments and the AI agent economy. Allaire noted that the digital dollar can be used for payments, transactions, lending and investments, adding that AI agents will participate in more economic activities in the future, which may further drive demand for the digital dollar and related blockchain infrastructure. However, he did not provide specific data on this demand growth. On the regulatory front, the U.S. Office of the Comptroller of the Currency (OCC) is drafting rules related to the GENIUS Act. The proposal requires stablecoin issuers to hold reserve assets equal to no less than the total value of their circulating stablecoins, redeem stablecoins at face value within two business days, and prohibits issuers from paying interest to holders. Allaire believes the GENIUS Act has bipartisan support and can provide policy safeguards for the stablecoin industry, though broader legislation on the U.S. crypto market structure has yet to make progress.

A critical security vulnerability has been exposed in PHP, the programming language used to run websites, affecting financial institutions, enterprises, local governments, and government agencies across Japan. Japanese Chief Cabinet Secretary Minoru Kihara stated at a press conference on the morning of the 22nd, "As of now, no reports of related damages have been received." Meanwhile, he advised enterprises and other institutions to install security patches, noting that the government will closely monitor the situation and take corresponding measures. According to Kihara, government departments including the Ministry of Health, Labour and Welfare and the Ministry of Finance have temporarily suspended the release of some website content as a preventive measure. Affected by the incident, Japan's cybersecurity-related stocks have risen, while no obvious fluctuations have been seen in the foreign exchange market and yen bond market so far. (Jinshi)

Glassnode released its weekly market report, stating that Bitcoin is constrained within a "trading range" of $80,000 to $87,000. Daily closes once rose above roughly $87,500, and recent ETF inflows paired with expanding trading volume show demand is absorbing supply at the upper end of the range. If Bitcoin breaks below $80,000, both ETF holders and average treasury investors will enter losses, potentially dragging the price down toward the True Market Mean. Below the range, buyers have re-accumulated positions near $80,000 based on ETF and Treasury cost bases (though at a smaller scale than the peak). Above the range, the cost basis for buyers who entered positions 6 to 12 months ago is around $86,700, paired with order book sell walls and liquidation clusters at roughly $85,000 and $87,000. A breakout from this range could accelerate, but will encounter selling pressure. Glassnode noted that investors should focus on upcoming key catalysts, including the Federal Reserve’s October 28 interest rate decision, rising oil prices and yields, and a rebound in inflation expectations. Separately, MSCI will publish its index adjustment list on November 11 (effective November 30), with potential removals of stocks such as Strategy, which could impact related equities and Bitcoin buying demand.
