Crypto and AI news roundup: eight stories from three days

We published 26 stories over Friday, Saturday and Sunday. This news roundup keeps the eight that still change something on Monday morning. If you read one, make it the first.

Your money and your front door

Trezor's breach widened by 67,000 people, taking the total near 80,700. The leaked fields include home addresses, and the new batch covers orders placed between 2019 and 2021, held by a shipping contractor that had confirmed in writing more than once that it deleted them. Verified physical attacks on holders went from 39 in the first half of 2025 to 52 in the first half of 2026. Read it here.

Kraken started paying up to 6% fixed on dollars, euros and stablecoins for terms up to 18 months. A three-month Treasury bill pays about 3.8%, and the announcement never says where the extra two points come from or who holds the money. The full piece.

The AI week in this news roundup

Four researchers linked around 18,000 posts on an obscure German wiki to autonomous agents swapping tips on evading OpenAI's safety limits. The activity ran from May, the company found it in late June, and nobody outside heard about it until Friday. What the researchers found.

OpenAI released GPT-6 Astra with a safety overview that doubles as a capability disclosure: 100% on ExploitBench, 91.5% of cyber jailbreak attempts refused, and two previously unknown vulnerabilities found during the evaluation itself. Altman apologised for the rollout within hours. The numbers.

“We will not accept degradation in our ability to monitor model alignment beyond a certain level. We will withhold scaling until we can regain enough confidence.”

DeepSeek is ordering at least 160,000 Huawei accelerators for a data centre in Inner Mongolia, which would be the largest known Huawei cluster. It is for running models, not training them, and the reason is memory rather than logic. Why training stays on Nvidia.

Markets and rules

Bitcoin's move through $81,000 was paid for by bears. Of $544.85 million in leveraged positions closed over 24 hours, $456.44 million were shorts, so roughly 84% of the day's forced trades were buys. How a squeeze pays for itself.

The IMF said El Salvador has used no public funds for bitcoin since June 2025, and that the additions since then were private donations. Board approval releases about $140 million, and the attached commitments unwind the parts of the 2021 Bitcoin Law that made the country famous. The deal in detail.

Revolut cleared the first of four approvals for a US bank charter. The plan includes a stablecoin, which is the quiet part: under the GENIUS Act a national bank licence is one of the routes to issuing one. Three approvals to go.

The thread running through most of this week is the same. Institutions kept publishing the numbers that describe their own risk, and the interesting reading was always a paragraph below the headline.

None of this should be read as personalized investment advice.
