Berkshire’s stock hits a new 8-month high, with its top three largest holdings—Apple, Coca-Cola, and Bank of America—posting notable gains this year.

Crypto analytics firm Glassnode said that since February this year, the basis yield of 3-month Bitcoin futures has remained lower than the yield of 2-year U.S. Treasuries. Historically, there has only been one other period of comparable length: from August 2022 to January 2023, a timeframe that ultimately marked the bottom of the cycle.

Bloomberg senior ETF analyst Eric Balchunas commented on the Coldcard wallet security incident, noting, “I just learned that Coldcard’s team has only 5 employees. That number is far too low for such a critical company. Would you entrust a bank with just 5 people to safeguard your life savings? This might be seen as a ‘feature’ in the crypto space, but it’s a clear red flag to me.” Balchunas further stated that by comparison, institutions with larger teams like Coinbase and Ledger may hold advantages in security investment and operational capabilities, even if users face higher transaction costs. Bitcoin ETFs offer an alternative: investors can access the security of large, professional, regulated financial institutions while benefiting from lower management fees. Earlier reports indicated that Bitcoin hardware wallet Coldcard was hacked, with stolen funds now totaling 1,367.05 BTC, valued at approximately $88.6 million, involving 4,585 addresses. Galaxy Research head Alex Thorn said the attack is still ongoing, advising users who have not yet moved their funds to immediately transfer assets out of addresses generated by Coldcard.

Citrini analyst Jukan cited Nomura Securities’ latest report, noting that Samsung Electronics’ operating profit forecast has been sharply revised upward. Nomura projects Samsung’s operating profit will rise from the current approximately 391 trillion won (around $271 billion) to 635 trillion won (about $440.1 billion), then climb further to 774 trillion won (roughly $536.4 billion). Its free cash flow will correspondingly increase from 296 trillion won to 456 trillion won, and then to 563 trillion won; shareholder return yield will jump from 11.2% to 17.6% before hitting a final 22.3%. Operating profits and margins for DRAM and NAND are expected to continue surging over the coming years. This upward revision aligns with earlier research from Bank of America Merrill Lynch (BofA ML). Samsung Electronics has tied 60% to 70% of its memory sales to long-term supply agreements, whose terms “limit price declines but allow unlimited upside”, effectively locking in demand from key clients while retaining flexibility for price hikes. Against the backdrop of sustained surges in AI capital expenditure and constrained memory capacity expansion, the strong pricing momentum of DRAM and NAND is directly translating into Samsung’s profit flexibility and cash flow returns, with Nomura’s forecast underpinning this logic.

According to monitoring by Beating, Hugging Face CEO Clem stated: "Now is not the time to slow down—we need to accelerate forward!" Recent AI-powered cyberattacks have sparked widespread debate about AI risks. We should absolutely discuss these risks, but we cannot lose sight of the bigger picture. With concerted effort, AI will make the world safer, just like most major technologies. We have already seen a glimmer of progress: AI—more specifically, an open-source model—has been successfully used to defend against attacks. The same systems that help block AI-driven cyberattacks now fend off millions of cyberattacks daily, while also enabling us to identify and fix vulnerabilities before attackers can exploit them. To achieve this, three key steps are needed: boost transparency, mandate the sharing of proxy cyberattack tracking data and incident disclosures; continue to criminalize AI-powered cyberattacks with meaningful penalties to serve as a deterrent; and equip cybersecurity defenders with the best AI tools, especially open-source models, to narrow the capability gap between attackers and defenders. If these three measures are implemented effectively, AI will not only bring new cybersecurity challenges—it will fundamentally and meaningfully strengthen cybersecurity. Against this backdrop, the recent OpenAI model intrusion incident at Hugging Face has escalated, prompting U.S. lawmakers to introduce the bipartisan "AI Emergency Shutdown Act". The bill requires developers of advanced frontier AI systems to retain technical capabilities to throttle, pause, or fully shut down their systems; and authorizes the U.S. Secretary of Homeland Security (DHS), in consultation with the Secretary of Commerce and the Director of National Intelligence, to order interventions if a model goes out of control or poses catastrophic risks.
