An Ethereum address dormant for 11 years was hit by a hacker's "poisoning attack" just three minutes after it came back online.

According to Barron's, Robbie Mitchnick, head of BlackRock's digital assets business, stated that since regulators approved in-kind crypto asset subscriptions and redemptions last year, the firm has recorded around $3.6 billion in in-kind conversions of directly held Bitcoin into shares of its spot Bitcoin ETF IBIT. As BlackRock does not handle all transactions itself and may not track every conversion, the actual volume could be larger. BlackRock also offers in-kind conversions for the iShares Ethereum Trust ETF and iShares Staked Ethereum Trust ETF, but their related volumes are far smaller than IBIT's. Mitchnick noted that demand for these conversions continues to rise, currently at the highest level of interest the firm has observed, and it does not fluctuate with Bitcoin's price. He added that the primary motivation is security and peace of mind: outsourcing custody to institutional cold storage models is more appealing to holders, and holding shares of a large fund manager's ETF is generally considered less risky than keeping assets on crypto trading platforms or always-on hot wallets. He pointed out that the recent Binance hack has once again highlighted the risks of trading platforms, though large Bitcoin holders have long understood these risks. The minimum threshold for in-kind conversions has dropped from an initial ~$30 million to around $1 million to $2 million, set by intermediaries facilitating the trades: Galaxy Digital, Talos, and Virtu. Mitchnick expressed hope that the threshold could be reduced to a single ETF share, but the cost structure will not fall to zero in the short term.

Beating AI Express (Dongcha) – Renowned developer and T3 Code founder Theo has discovered that while Anthropic’s newly launched Fable 5.2 is more capable, the equivalent API usage available to subscribers is far lower. Theo has long tracked actual request data for Claude Code. According to his estimates, for the same $200 monthly Claude Ultra subscription, using Opus 5.5 yields around $15,000 in equivalent monthly API usage, while switching to Fable 5.2 only delivers about $3,000 — a difference of nearly fivefold. Anthropic also stipulates that Ultra users can allocate a maximum of 50% of their total weekly quota to Fable. Even if the full quota is not exhausted, once the Fable limit is hit, users must either switch to another model or pay extra to continue using it. Theo further estimates based on real-world workload: using Opus 5.5 exclusively for a week allows roughly 1,200 interaction rounds and 230 task sessions. If users first use up their Fable quota before switching to Opus, total interaction rounds drop to around 900, though the number of completed task sessions may be slightly higher, as Fable can sometimes finish tasks in a single turn without repeated back-and-forth communication. Fable 5.2’s API unit price is 20% lower than its predecessor, at $8 per million input tokens and $40 per million output tokens — yet it remains twice as expensive as Opus 5.5. Anthropic has explicitly warned that Fable consumes subscription quotas faster than other Claude models. Currently, Anthropic is providing eligible subscribers with 1 to 3 Fable quota reset opportunities, with the number tied to subscription duration. Each reset refunds the Fable quota consumed that week, letting users resume usage without waiting until the next week.
