JUST announced an upgrade to the buyback and destruction mechanism for JST. After completing the fifth round of buyback and destruction, the mechanism officially enters a new phase: governance will be unified by the JUST DAO, and a reserve fund of no less than 50 million USD will be established for risk mitigation, emergency redemptions, and liquidity support, to enhance the mechanism's risk resistance and execution stability.On the buyback side, it will shift to being executed based on the quarterly sustainable income of the JUST ecosystem, forming a normalized arrangement of long-term buybacks and regular destructions, making the scale of buybacks more closely tied to the actual income of the ecosystem.In addition, the remaining surplus funds above the reserve threshold, approximately 20.34 million USD, will be released in four phases starting from Q4 2026 to supplement the buyback, ensuring long-term deflation and stability of the mechanism. The complete announcement and implementation details can be found through official channels.

JUST announces the official release of the new white paper. As an important ecological document following the brand upgrade, the new white paper systematically outlines the JUST ecological architecture, the positioning and collaborative relationships of the three core product lines, and provides detailed explanations of the updated JST token economics, covering key content such as governance mechanisms and buyback and burn arrangements.The new white paper helps users, developers, and the community to gain a more comprehensive understanding of the upgraded ecological layout, token mechanisms, and long-term development direction, further enhancing ecological transparency and providing a clear reference for subsequent ecological participation and development integration.

The hedge fund Bridgewater's China business department informed investors that the institution's bullish stance on gold has decreased and that it holds a cautiously optimistic view on the domestic Chinese stock market. The Shanghai-based hedge fund stated in a letter to investors in September that it has gradually reduced its previously overweight position in gold.Bridgewater China noted that rising interest rates have increased the opportunity cost of holding gold, while rising oil prices have suppressed demand from energy-importing countries like India. The institution also expressed optimism about Chinese assets, believing that the current stock market valuation is not high, the policy direction is favorable for long-term capital formation, and that there may be more funds flowing into the stock market in the future against a backdrop of lower bond yields.

Bitcoin core developer Antoine Poinsot announced an adjustment to the security vulnerability disclosure policy in the Bitcoin development mailing list. He stated that in the past, vulnerabilities were often kept secret for a long time to allow users to complete upgrades before details were made public, but this also led to fixes not being backported to older versions, requiring users to wait for the next major release. Poinsot pointed out that large language models make some vulnerabilities very easy to rediscover, and the protection that continued delays in fixing can provide is now quite limited.According to the new policy, vulnerabilities deemed "easy to discover" will be fixed as soon as possible in all maintained major versions, with security announcements released simultaneously. This classification applies to vulnerabilities that can be discovered with minimal effort, such as through simple LLM prompts. Other vulnerabilities will still follow the disclosure timeline based on severity: low-severity vulnerabilities will be disclosed two weeks after the major release containing the fix; medium to high-severity vulnerabilities will be disclosed two weeks after the last affected version reaches its end of life (usually one year after the fix is released in a new major version). Critical vulnerabilities are not covered by the standard policy and may require ad hoc procedures.Bitcoin ecosystem security researcher Luke de Wolf stated that he previously disagreed with Poinsot's security strategy but believes this update is a good adjustment. In August of this year, the volunteer-based Bitcoin Red Team reported nearly 5,000 potential issues across 390 projects, with only about one-fifth being reproducible at that time. In the same month, Core Lightning developers urged operators to upgrade or take nodes offline after receiving multiple AI-generated vulnerability reports, while keeping technical details confidential for two weeks.

The official listing account of the cryptocurrency exchange Kraken announced that the token SFI of the peer-to-peer risk-adjusted protocol Saffron will be launched soon, with trading starting on October 23.

According to Cointelegraph, Coinbase's European policy director Katie Harries wrote that the proposed cryptocurrency asset regulatory rules by the UK's Financial Conduct Authority (FCA) may require regulated platforms to execute customer orders only on trading venues authorized by the FCA, thereby restricting users' access to decentralized finance (DeFi) protocols through compliant platforms.Since decentralized protocols typically do not have entities that can apply for regulatory authorization, the relevant rules may lead to regulated platforms being unable to provide DeFi access services, effectively creating a ban. The related cryptocurrency regulatory system is expected to be implemented starting October 25, 2027.

According to the official announcement, Binance will update the full margin borrowing and withdrawal collateral rates for POL, SHIB, XLM, COW, NEXO, RVN, and SAND on October 23, 2026, at 06:00 (UTC). The update is expected to be completed within 30 minutes.

The decentralized perpetual contract trading platform Aster announced that, in light of recent developments related to PAPER and potential market risks, it has adjusted the pre-market perpetual contract for PAPER to a liquidation-only mode and plans to officially delist the contract at 9:45 AM Beijing time on October 20. Aster recommends that users holding open positions proactively close their positions before the delisting, calling this a precautionary measure to manage market risks and maintain trading order.Previously, Papertrade stated that there are currently no plans to allow external transfers of the PAPER token and will adjust short-term trading fees and the token issuance curve. The team believes that the PAPER perpetual contract could make the liquidity pool's solvency a target for short selling, and external short exposure may increase the profit potential for manipulation attacks, as these markets are not controlled by the protocol.Papertrade founder Jez also pointed out that due to the rapid progress of the perpetual contract market, PAPER is currently set to a non-transferable status to avoid potential attack risks and maintain the long-term healthy development of the protocol. Jez emphasized that PAPER represents users' rights to the protocol's earnings, and its long-term value depends on whether Papertrade can continue to attract traders. The team made this risk management choice based on the operational data from the first week after the protocol's launch.

According to Bitcoin Magazine, Richard Byworth previously worked at Syz Capital, focusing his career on hedge fund structure design. In an interview with Bitcoin Magazine, he stated that the next round of Bitcoin's rise is just a matter of time.He pointed out that, based on data from on-chain analysis platforms like Glassnode, the current level of seller exhaustion has reached a historical high. Although the market does not exhibit an extreme bearish atmosphere, multiple on-chain indicators show that Bitcoin is strongly building a bottom. He mentioned that Bitcoin has been trading in the range just above $80,000 in recent weeks, and he believed that $58,000 was a bottom.Byworth also discussed Bitcoin yield strategies. He warned that using a covered call strategy during a bullish market could lead to significant losses of Bitcoin for investors, and advocated for earning low-volatility, market-neutral returns through basis trading collateralized by Bitcoin. He noted that Strive had bought three times the weekly issuance of Bitcoin in a single transaction within a week, believing that the next round of rise is just a matter of time.Regarding Bitcoin treasury companies, Byworth stated that the digital credit products designed by Saylor are putting pressure on the traditional bond market, as the yield on 10-year U.S. Treasuries is around 5.1% to 5.2%, and investors will see their returns eroded by the faster pace of currency depreciation. He mentioned followers like Strive and Metaplanet, and believes that Bitcoin could break its historical high again before the end of the year, and reaching $350,000 in about a year is not entirely impossible.

The Hyperliquid Policy Council (HPC) stated that it has submitted a comment letter to the U.S. SEC in support of its proposed Regulation Crypto Assets and suggested 5 adjustments to the final rules to further clarify the regulatory boundaries regarding token issuance, airdrops, secondary market trading, and safe harbors.

JustLend DAO announced the cumulative results of the five rounds of buyback and destruction of $JST: a total of 1,881,973,007 JST has been destroyed, accounting for 19.01% of the total supply, with an estimated cumulative destruction value of approximately 118.15 million USD.This deflationary mechanism is built on the protocol's revenue, with each round of buyback and destruction transparently recorded through on-chain transactions, publicly verifiable, reflecting the continuous execution and traceability under the community governance framework. As the circulating supply gradually decreases, the long-term value support and ecological sustainability of JST are further strengthened, laying a solid foundation for the normalization of future buyback and destruction mechanisms.

According to CoinDesk, during the market closure on Saturday, leveraged bets linked to chip stocks and semiconductor funds were liquidated for nearly $52 million within 10 minutes. According to CoinGlass data, approximately $51.6 million in chip stocks and semiconductor fund-related positions were forcibly closed between 21:22 and 21:32 UTC, of which about $38 million came from bullish bets on rising prices. The sell-off began at Binance and quickly spread to Hyperliquid within seconds.The SOXL contract, which is three times long on chip stocks, suffered the largest loss, approximately $12.7 million; contracts for SanDisk and SK Hynix each lost about $10.8 million. According to David Jeong, CEO of trading firm Tread.fi, he placed the first large sell orders for SanDisk and Micron on Binance at 21:21:59 UTC, and less than a second later, the orders impacted Hyperliquid—this platform, launched by Trade XYZ, tracks contracts for stocks, with about 10 addresses establishing short positions on 6 chip-related contracts within 1.8 seconds. In the first minute, Binance processed approximately $21.9 million in SanDisk trades, while Trade XYZ accounted for $3.1 million.Storage chip stocks had already experienced a tumultuous week due to new competition from Chinese chip manufacturer CXMT. With the stock market closed, these contracts had no real stock prices for reference, and traders could only compete against each other; the rules of Trade XYZ allow the platform to set reference prices independently before external stock quotes resume, with relevant quotes returning when U.S. stocks open on Monday.
