On October 22, a16z announced the removal of "Crypto" from the name of its flagship blockchain fund, renaming it to a16z Frontier, and long-time general partner Ali Yahya is stepping down. The announcement stated that this move does not signify a withdrawal from investing in the cryptocurrency space, but rather aims to further broaden the investment scope.The fund has previously raised nearly $10 billion, including $4.5 billion in 2022 and $2.2 billion for Fund 5 this year, making it one of the largest institutional players in the industry. When raising Fund 5 this year, a16z stated that the industry is shifting from a price cycle to a usage cycle, focusing on the infrastructure of stablecoins, on-chain finance, prediction markets, and asset tokenization, rather than merely chasing market trends.Chris Dixon, founder and managing partner of a16z crypto, will remain in his position. Investments related to crypto assets and blockchain remain one of the core directions, but the overall label and strategic focus have been adjusted to cover a broader range of frontier technology fields.

According to Bloomberg, Amazon's threat intelligence team discovered that hackers attempted to exploit related vulnerabilities days before the public disclosure of two security vulnerabilities in PHP. After the vulnerabilities were disclosed on Wednesday, hacker activities further expanded. Amazon stated that the related vulnerabilities are being widely exploited but did not disclose specific victim information.Cybersecurity company Palo Alto Networks found that there are over 22.6 million exposed instances worldwide with related vulnerabilities. Wiz researchers estimate that the vulnerabilities could affect about 70% of the internet and have existed for over a decade, while Matt Hull, Vice President of Cyber Intelligence and Response at NCC Group, warned that some vulnerable systems may have already been compromised or even implanted with backdoors.

Cryptocurrency market analyst Murphy stated that BTC has accumulated approximately 921,000 chips around the $83,000 mark, approaching the milestone of 1 million. The last time a similar scale was observed was on August 3 of this year, when the chips at that price level reached about 1.05 million.Regarding the historical Coinbase wallet chips that may be included, Murphy indicated that about 550,000 BTC are related to the Coinbase wallet consolidation from a year ago, but it is currently unclear how many positions remain. According to his estimates, there may only be 100,000 to 200,000 left, so this factor can be temporarily ignored. BTC has entered the first chip gap area below $83,000. Since the price did not fully exchange hands when passing through this area previously, the price returning to this range creates an attraction effect, prompting chips to be re-exchanged and fill the gap.BTC faced resistance when attempting to move downward and may look for a direction with less resistance again. The $83,000 mark is also an important focus in the current long-short battle; any party gaining an advantage could drive the market to form a new trend.

Galaxy Research Research Director Alex Thorn stated that since the second half of October, Bitcoin returns have been primarily driven by the Asian trading session, while the European trading session has dragged down overall performance.The chart he shared shows that as of October 20, calculated from October 1, the cumulative return of Bitcoin during the Asian trading session was 3.9%, 1.1% during the U.S. trading session, and -5.5% during the European trading session; the return for buying and holding all day during the same period was -0.7%.

According to Cointelegraph, Bitwise Research Director Ryan Rasmussen stated that in the third quarter of 2026, the overall purchasing of Bitcoin by treasury companies slowed down, with a net increase of 1,666 BTC for the Strategy that quarter, down from 83,901 BTC in the second quarter; other listed companies had a net increase of 5,617 BTC, down from 45,725 BTC in the previous quarter. He expects corporate purchases to accelerate again as early as this year.Bitfinex Derivatives Director Jag Kooner mentioned that if the stock prices of treasury companies rise above the value of their holdings, it may restart stock purchases, but "the likelihood of returning to last year's indiscriminate financing wave is low," and funds will prioritize mature companies with scale, liquidity, and a proven track record.

The analysis agency Sentora stated that approximately $1.63 billion in Ethereum lending platforms were liquidated in the past year, with 89% completed through atomic paths. Atomic liquidation relies on DEX liquidity. The thin liquidity pools and the existence of whitelist transfer restrictions on RWA collateral will drive more liquidations towards off-chain market makers, RFQ, and solver paths.Atomic paths refer to the completion of collateral liquidation and debt repayment within the same on-chain transaction. Common methods include flash loans, self-funding advances, or direct contract calls. In contrast, RWA is often difficult to clear instantly on DEX, and liquidations will increasingly be handled by compliant off-chain market makers through price inquiries and solvers taking over collateral before completing the liquidation.

Glassnode and Coinbase Institutional jointly released the Q4 2026 "Charting Crypto" report. The report suggests that Bitcoin has transitioned from a bottoming phase to an initial recovery in Q3, with an overall positive outlook for Q4, although caution is still advised in the short term.The report shows that the net unrealized profit and loss indicator (NUPL) for Bitcoin has returned to the "optimistic/anxious" range, still below the threshold of the "belief/denial" phase. The supply of Bitcoin that has not moved for over a year continues to increase, with long-term holders largely maintaining their positions during the rebound, and the return of new participants has driven a recent rise in active supply. As of the end of September, there is a dense cost area for Bitcoin above the price, which includes the resistance area that previously limited the rise in September, while multiple layers of support are distributed below.

On October 15, the semiconductor research organization SemiAnalysis published an article stating that the lithography equipment manufacturer ASML has not officially announced related products, but patents, news reports, and the company's roadmap all indicate that it is developing hybrid bonding equipment. The author of the article judges that ASML may first launch more challenging chip-to-wafer hybrid bonding tools and view it as an extension of vertical integration.Patents show that the system operates on a track, with each chip placed in an independent carrier, sequentially completing inspection, cleaning, plasma activation, morphology inspection, leveling, coarse alignment, position adjustment, and fine alignment before entering the bonding station; the final placement is completed by the carrier and suction cup. The track's repeat accuracy is about 10 microns, far from the approximately 50 nanometers required for bonding. ASML submitted 27 bonding patent families from December 2022 to November 2024, most of which are aimed at chip-to-wafer. The Elec reported in March that ASML has begun hybrid bonding machine architecture design with Prodrive Technologies and VDL ETG.The article states that wafer-to-wafer hybrid bonding has been used for image sensors and 3D NAND; chip-to-wafer is currently only used for mass production of logic chips, including AMD's hybrid bonding V-Cache shipped since 2022 and TSMC's SoIC. The current spacing of SoIC is about 6 microns, with a target of reaching approximately 4.5 microns by 2029. Besi is currently the only supplier with chip-to-wafer mass production tools, with related logic business mainly concentrated in TSMC and Intel.

In September, the U.S. CPI rose 3.7% year-on-year and 0.6% month-on-month, while the core CPI increased 2.6% year-on-year and 0.3% month-on-month, all exceeding market expectations. Following the data release, market bets on a 25 basis point rate hike by the Federal Reserve in October rose to about 40%, up from around 20% the previous day.The Federal Reserve just raised rates by 25 basis points last month, marking its first rate hike of 2023. The next rate decision will be announced on October 28, just 6 days before the U.S. midterm elections on November 3. Inflation continues to remain above the Federal Reserve's 2% target, and economic activity remains resilient, providing grounds for further rate hikes.Economists from institutions such as Jefferies and Nationwide believe that there is data support for rate hikes in both October and December. Some analysts also expect that the Federal Reserve may consider the timing of the elections and potential economic vulnerabilities, choosing to delay until December. Historical data shows that the Federal Reserve rarely raises rates in October or November before midterm elections, and the market will be paying attention to Federal Reserve Chairman Kevin Walsh's remarks before entering the pre-meeting blackout period.

According to "Du Jia," Tencent is conducting a small-scale test of its personal investment analysis assistant "Rena Lan Cai," which has a PC version and a WeChat mini-program, supporting connection to WeChat. This product is positioned as an AI assistant for individual investors, helping users obtain and understand market and company information, and is currently in a small-scale testing phase.The web version breaks down the investment research workflow into visual modules, with core features including market quick reads, individual stock tracking, and AI Q&A. The market quick read summarizes global market dynamics, continuously updated in the morning, noon, closing, and evening, and associates market information with the user's watchlist; the left sidebar allows users to customize stocks of interest and displays real-time market data, while the right side features an intelligent Q&A panel linked to the day's quick read content, supporting follow-up questions about industry rankings, cash flow in financial reports, and more. In addition to the PC version, Rena Lan Cai is also launched as a WeChat mini-program, with basic functionality aligned across both platforms and conversation records shared. The product also appears in the WeChat chat list as a WeChat ClawBot intelligent entity, allowing users to directly access investment research capabilities in the chat window.The report states that Alibaba is also internally testing its AI investment research product Qovest, and Baidu's previously released Kuku AI is also focusing on investment research, as major companies collectively enter the personal investor AI investment research space. Rena Lan Cai essentially serves as an investment research assistance tool, not providing investment advice and avoiding direct trading compliance red lines.

Cryptocurrency market analyst Axel Adler Jr. stated that on-chain data shows the average cost basis for Bitcoin long-term holders (LTH) is $48,600, with the current price approximately 72% higher than their cost. This group has remained profitable since January 2023, with the last close to the cost line occurring in March 2023.The average cost basis for LTH peaked at $49,500 on July 30 and has since decreased by 1.7%. Since August 1, there have been 60 negative weekly changes out of 74 days, with the largest single-week decline being 0.34% on August 25, and the current reading is -0.06%. The analyst pointed out that this decline is still moderate, and if it continues to drop, it would indicate an acceleration of selling, while a return to positive values would mean that long-term holders are starting to accumulate again.

AI Proem author Grace Shao stated on October 9 that China has long accumulated a large amount of data, but has yet to see large independent AI data companies similar to Surge AI, Scale AI, and Mercor in the United States. She wrote that the relevant background includes the formation of cutting-edge models and upstream data markets in the United States, while Chinese tech giants have long kept data within closed ecosystems, and the data of enterprises and traditional industries is scattered, with state-owned enterprises unwilling to easily hand over data to external suppliers.The article cites data from the National Bureau of Statistics, stating that by 2025, China will generate 52.26 ZB of data, with only 22.13% of the stored data classified as structured data. An interview with Lin Zhenya, CTO of Benyuan Zhishu, by Data Monkey mentions that there are about 2,000 to 3,000 labeling companies in China, with the top three accounting for about 20% to 30% of the market, while he estimates that the top three in the United States account for about 70% to 80%. The author notes that this is an industry estimate, not an independently calculated market share.The Information reported in September 2025 that Beijing-based company UniPat completed financing with a pre-investment valuation of $1 billion, while competitor Humanlaya's post-financing valuation is close to $1 billion. Both companies received investment from HSG and are reportedly serving Alibaba, ByteDance, The Dark Side of the Moon, and DeepSeek. A Hong Kong Stock Exchange announcement from Qian Baidu shows that the company will acquire approximately 90.91% equity in Benyuan Zhishu for 300 million yuan in June 2026. Haitan Ruisheng's 2025 annual report shows a year-on-year revenue increase of 59% to 377 million yuan.

Cryptocurrency market analyst Darkfost stated that despite Ethereum recently falling from $2775 to around $2500, a decline of nearly 10%, the nominal value of Binance's ETH futures open interest decreased by about $600 million during the same period. However, when measured by the number of ETH, the open interest size has still rebounded to the level at the end of September, approximately 2.46 million ETH.Between October 8 and 9, the market liquidated about $345 million in ETH long positions within 24 hours. However, Binance's share of open interest in ETH futures on major centralized trading platforms actually rose to nearly 49%, reaching a new high since 2023.Darkfost pointed out that this means that despite the pullback in ETH prices and some leveraged positions being liquidated, the amount of ETH that traders are putting into the Binance futures market has not significantly decreased, further increasing Binance's dominance in the ETH derivatives market.

According to CoinDesk, several blockchain analysis companies estimate that the assets stolen by attackers from hundreds of wallets associated with the authorized dealer CryptoBilis sold Ledger devices could be as high as $94.5 million. Ledger has not yet confirmed this total.Hardware wallet company Ledger discovered that unauthorized hardware was implanted in at least one affected device; stablecoin issuer Tether has frozen $10 million USDT related to the theft, and investigators are still tracking the flow of funds. Ledger advises CryptoBilis customers not to set up devices that have not yet been used; customers who are already using the related devices should transfer their assets to new devices and generate new recovery phrases.

Cryptocurrency analyst Darkfost stated that currently, above the price level of approximately $83,000, 53% of the invested capital is concentrated. This means that if Bitcoin is purchased at this level, the holding cost will be better than that of more than half of the investors.The range of $84,000 to $85,000 is the largest chip distribution cluster, and many investors react at this critical level, so this range is clearly the core resistance that Bitcoin must break through. Looking below, the range of $79,000 to $77,000 may become a support level. If the price cannot effectively break through $84,000-$85,000, the market may first retest this support area; however, once it stabilizes above the densely concentrated chip area, it means that the cost pressure for most holders has been digested, and the subsequent upward resistance will be significantly reduced.

Account @blockchainchick stated that Tether's USDT contract has included the destroyBlackFunds function since its deployment on Ethereum in 2017. This function first confirms that the address has been blacklisted, then reads its balance, sets the balance to zero, deducts the corresponding amount from the total supply, and records the event, with no function available to reverse it.The account mentioned that the relevant blacklist function names the target address as _evilUser, and only Tether's multi-signature owners can invoke it on Ethereum and Tron. It also stated that Tether can subsequently mint an equivalent amount of USDT to the selected address, keeping the net supply unchanged; the U.S. Department of Justice described this process in a March 2025 forfeiture case in Massachusetts, involving approximately $9,016,612 USDT. The account also claimed that USDC can restrict wallets but cannot destroy balances, and believes this mechanism has been operating on Tron and Ethereum with owners, while Bitcoin does not have this feature.

The Chief Information Security Officer of Slow Mist Security, 23pds, stated that if the modification of the Ledger device's PCB is indeed as described by former Mt. Gox CEO Mark Karpelès, the attacker would possess a considerable level of technical skill.23pds mentioned that the possible attack process involves the wallet generating a mnemonic phrase within a secure element and displaying it on the screen for the user to write down. A malicious module could obtain the displayed content through screen data lines such as SPI, record the complete mnemonic phrase, and then send the data to the attacker via LTE/eSIM. The secure element can prevent the private key from being directly read or exported, but it cannot stop external modules from accessing the information currently displayed on the screen. He noted that the above analysis is based on the premise that the PCB has indeed been modified in the described manner, and the relevant attack paths and hardware implantation still require independent verification.Mark Karpelès previously stated that a Ledger hardware wallet he received was suspected of being implanted with a spy module. The device came from Malaysia, the outer packaging was intact with shrink wrap, and the implant was hidden in the position where the screen originally had a cushion, containing LTE communication components, an antenna, eSIM, and a microcontroller connected to the Ledger SPI bus, capable of analyzing the characters displayed to the user and sending relevant data after the mnemonic phrase setup is completed.
