Co-founder of Glassnode, Rafael Schultze-Kraft, stated based on on-chain data that approximately 6.26 million BTC public keys have been exposed, accounting for 31.2% of the current supply, up from 24.8% at the beginning of 2021.Among them, about 4.33 million were exposed due to address reuse, and approximately 1.94 million are related to script types. He emphasized that this statistic does not indicate that quantum attacks are realistically feasible, nor can it be used to assess the security status of exchanges or custodians.

The cryptocurrency research platform Glassnode pointed out in the latest issue of The Week Onchain report that within the 30 days ending on October 5, approximately $4.9 billion of "new funds" flowed into Bitcoin, covering corporate treasury purchases, stablecoin growth, and inflows into U.S. spot Bitcoin ETFs. During the same period, Bitcoin achieved a market capitalization increase of $12.8 billion, more than double the size of the new funds.Glassnode stated that new funds only accounted for less than two-fifths of this increase, with the remainder coming from existing market funds being traded at higher prices. Data shows that since the launch of the spot ETF in January 2024, Bitcoin's upward trends have shown similar differentiation, but the scale of inflows accompanying the rises in 2024 and 2025 is far greater than the current situation. Glassnode noted that before inflows recover, the market will rely on existing holders to pay higher prices.Since September 21, Bitcoin has attempted to break through $87,000 four times without success, and as of the time of writing on Thursday, it was around $83,000, down 1% for the month. Glassnode pointed out that on the first week since January when Bitcoin closed above $85,000, about 86% of the tokens transferred to exchanges came from short-term holders who had held for less than 155 days and were in profit, marking the highest single-day proportion in the past year. CryptoQuant data shows that as of October 7, the overall cost basis for short-term holders is approximately $78,250, still in a net profit state.

On the evening of October 6, HTX DAO Ambassador Molly stated at the HTX DAO "Night of the Future" event held in Singapore that HTX DAO is continuously investing in three directions: ecological mechanisms, community building, and on-chain ecology. By continuously optimizing the token economic mechanism, expanding ecological application scenarios, and advancing relevant ecological initiatives according to established mechanisms, a solid foundation for long-term ecological development is being laid.Regarding community building, Molly revealed that HTX DAO plans to promote the construction of regional community nodes in the fourth quarter, supporting community members to organize activities, participate in exchanges, and co-build community culture. Currently, the number of active volunteers participating in community building has approached 200, and there are plans to further expand community participation in the future. In terms of on-chain ecology, HTX DAO is attracting developers from global universities to participate through hackathons and other means, with several projects currently in further incubation or advancement stages, exploring integration with $HTX ecological application scenarios.Molly emphasized that ecological construction requires long-term investment. HTX DAO will continue to improve infrastructure, cultivate active communities, and promote the implementation of ecological applications. She also stated that as one of the participants in the HTX DAO ecosystem, Huobi HTX is also continuously optimizing user experience, including optimizing withdrawal fees, collecting user feedback, and improving the App usage experience, to better respond to user needs and market changes.

On-chain data analysis platform Glassnode stated that the largest liquidation cluster for Bitcoin is located around $90,000. If the price reaches this level, leveraged shorts will be forced to close their positions.Glassnode noted that when looking back over the past two months, smaller liquidation clusters can be seen around $83,000 and $75,000. Regardless of which side the price touches, it could accelerate the next round of market fluctuations.

According to Glassnode data, long-term holders of BTC have remained in profit throughout this cycle. This has never happened in previous bear markets since at least 2015.In each previous bear market, the long-term holder MVRV (LTH-MVRV) indicator would drop below 1 at the bottom of the cycle, causing this group to fall into a loss. However, this time, the indicator bottomed out above 1 and is currently rising again.

According to monitoring by Bitcoin News, Core Lightning stated that attackers are targeting nodes still running version 26.06.7 and earlier. The patch released on September 22, version 26.06.8, fixed a channel closure issue that could jeopardize funds, as well as vulnerabilities that could lead to crashes and memory exhaustion.The project has not disclosed the names of the vulnerabilities used by the attackers, nor has it reported any theft of funds. Node operators who have not yet upgraded are becoming the targets of the attacks.

The privacy coin project Zcash officially stated that Zcash now has two independent full node implementations, both executing the same rules, namely Zebra and Zakura.Zcash also raised the question: Does the second client truly change the decentralization of the network, or is computing power still the only key factor? Zebra is the Rust full node implementation supported by the Zcash Foundation, while Zakura is another independent full node client.

According to monitoring by Glassnode, investors who previously bought at high prices in the Bitcoin market are currently selling off. Data shows that there are two groups currently in a loss state: one group consists of investors who bought at a price of $97,000 one to two years ago, and the other group consists of investors who bought at a price of $89,000 six to twelve months ago.Analysis indicates that investors who entered during the price increase in 2025 are currently selling the most Bitcoin daily, while those who bottomed out during the market decline show a strong willingness to hold and are not selling off in large quantities.

According to official news, TRON has officially released the GreatVoyage-v4.8.2.3 (Anaxagoras) version.The new version focuses on improving the smart contract storage access mechanism, enhancing the performance of BN128 pairing operations, and optimizing the parsing process of JSON data generated by nodes, further enhancing node operational efficiency and stability.This version is a mandatory upgrade, and TRON reminds node operators to complete the update as soon as possible to avoid affecting block synchronization. After the upgrade is completed, relevant nodes can promptly report their deployment status so that the community can continuously track the overall network upgrade progress.For specific version changes, GPG signature verification, and deployment methods, please refer to the official version release notes and upgrade deployment documentation.

The Core Lightning team, which develops the open-source Bitcoin Lightning Network node software, has issued an urgent alert stating that reports indicate attackers are targeting nodes that have not installed patches, urging operators still running old versions to upgrade immediately. The team stated: "Emergency security update: If you are using version 26.06.7 or earlier, please upgrade to the latest release as soon as possible."Prior to this, Core Lightning began investigating a potential issue that could affect its experimental features and, in turn, impact user funds on September 16, and approximately six days later, version 26.06.8 was released. This update not only fixed several defects but also provided patches for security vulnerabilities reported responsibly by multiple parties, thanking the Bitcoin Red Team and 12 other individuals and organizations in the release notes, while also acknowledging anonymous reporters.According to the changelog, this round of fixes covers a bug that could cause sender nodes to crash, requests that could exhaust REST interface memory, and a vulnerability that could result in user funds facing confiscation losses when closing payment channels. To provide operators with ample upgrade windows and prevent attackers from taking advantage of reverse engineering and exploitation, this version intentionally obscured some testing content. Additionally, in August of this year, the project initiated a collaborative fixing process after reviewing a large number of AI-generated general vulnerability disclosure reports, and two days later released version 26.06.7 to close confirmed vulnerabilities.

On-chain data analysis platform Glassnode stated that the sell wall above Bitcoin has disappeared. The buy orders absorbed the sell wall at the $85,000 level yesterday, which had been tested multiple times over the past week but failed to break through.Glassnode indicated that the remaining sell orders also seem to have been removed. With the reduction in sell-side liquidity above, the price may rise more quickly.
