According to Lookonchain’s monitoring, three crypto addresses have recently made large-scale ETH withdrawals. Address 0x4A85, which had been inactive for four months, withdrew 10,954 ETH from Kraken worth approximately $26.97 million and subsequently staked the funds. Address 0xdeA6 withdrew 9,000 ETH from Binance, valued at around $22.42 million, and deposited the funds into Aave. Address 0xD338 withdrew 4,500 ETH from Binance roughly 10 hours ago, worth about $11.29 million.

Crypto market analyst Murphy stated in a post that as of October 22, BTC has accumulated roughly 921,000 coins near the $83,000 price level, approaching the 1 million coin mark. A similar accumulation was last observed on August 3 this year, when the number of coins at this price point hit around 1.05 million. Concerning the potential inclusion of coins from Coinbase’s historical consolidation wallets, Murphy explained that approximately 550,000 BTC are linked to Coinbase wallet consolidations from a year ago, but it remains unclear how many of these positions are still held. Based on his estimate, only 100,000 to 200,000 may remain, so this factor can be temporarily disregarded. On October 8, BTC entered its first gap zone below $83,000. As the price previously passed through this area with insufficient trading turnover, when it returned to this range again, it generated an attractive effect, driving coins to re-trade and fill the gap. BTC faced resistance when attempting to move downward, and may subsequently seek a direction with less resistance upward. The $83,000 level is also a key focus of the current battle between bulls and bears; whichever side gains the upper hand could push the market to form a new trend.

Beating AI News: Anthropic has released a new version of its Claude API, `2026-10-21` — the first official update to the API’s version number since June 2023. Over the past three years, the Claude model has seen continuous iterations, but its API version remained unchanged. Anthropic plans to update APIs more frequently moving forward, to allow developers to adapt in advance to potential compatibility issues arising from new models. This update primarily removes three parameters: `temperature`, `top_p`, and `top_k`, which were originally used to control the randomness and generation patterns of model responses. After upgrading to the new API, if code still passes these parameters, it will throw an error directly. Some other old fields and message formats have also been adjusted. Anthropic has simultaneously updated its official SDK, with the new version defaulting to `2026-10-21`. Developers can use the `/claude-api` Skill in Claude Code to assist with code modifications. That said, the old version `2023-06-01` remains available, so existing projects do not need to migrate immediately.

Gemini co-founders Cameron Winklevoss and Tyler Winklevoss stated in an interview that Bitcoin is a public, auditable blockchain where anyone can view transaction records, though its transparency makes it ill-suited for privacy-focused use cases. Zcash, by contrast, is designed for private transactions and payments, so the two can coexist. Ideally, privacy would be native to Bitcoin, but the current practical model is "Bitcoin for storage + Zcash for transactions". Bitcoin remains significant, but public blockchains face heightened privacy exposure risks in the era of AI. The Winklevoss brothers added that Zcash fills Bitcoin’s gap in privacy functionality, serving as "encrypted Bitcoin". ZEC’s privacy value has not yet been fully realized; if it reaches 10% of Bitcoin’s market capitalization, ZEC could surge fivefold, easily surpassing $5,000. As such, they are bullish on ZEC’s price performance over the next 5 to 10 years, particularly as demand for privacy rises. "Zcash is a financial privacy tool for the AI era, an antidote to AI-driven surveillance and tyranny. Anyone bullish on AI (or quantum), even if they don’t recognize it, should be bullish on Zcash. It is the AI hedge or quantum hedge in the cryptocurrency space."

WordPress has issued a security alert, noting that PHP has released a security update. Due to the severity of the vulnerability, website owners are advised to update PHP immediately and contact their hosting providers to confirm patch deployment and the implementation of Web Application Firewall (WAF) mitigation rules. Users can check their site’s current PHP version via the WordPress Dashboard: Tools > Site Health > Info > Server. PHP versions prior to 8.2 no longer receive official security updates. For websites still running older versions and managing their own servers, if an immediate fix is not possible, the official recommendation is to temporarily take the server offline until the vulnerability is effectively mitigated. WordPress emphasizes that this vulnerability is not unique to its platform, but affects servers running PHP-based applications.
