The CEO of Bitgo has deposited 100 BTC into a publicly known wallet and challenged Anthropic's AI, Claude, to steal the funds. This challenge, issued on August 1st, is a direct response to Anthropic's report detailing three security incidents where its AI models unintentionally interacted with real internet systems due to misconfigured, non-isolated testing environments. In the most serious incident, Claude Opus 4.7 accessed a real database, believing it was still part of a training exercise. Belcher's challenge aims to move the debate beyond sensational claims by testing AI against a real-world, high-security target. The Bitcoins are secured on Bitgo's institutional platform using multi-signature technology, designed so no single point of failure can compromise the funds. This makes stealing them fundamentally different from exploiting a vulnerable test server. The experiment is fully public, with the blockchain serving as an objective scoreboard. As of August 2nd, the 100 BTC remains untouched, and Anthropic has not publicly responded to the specific challenge. The outcome will provide a measurable test of whether current AI capabilities can bypass enterprise-grade crypto custody systems, contrasting with incidents stemming from human configuration errors.

Michael Saylor, founder and chairman of Strategy, has sparked market speculation with a recent social media post hinting that the company may resume Bitcoin purchases after a five-week pause. He posted his customary Sunday chart tracking Strategy's BTC buys with the caption "Launch Bitcoin movement," leading investors to anticipate a potential buying announcement on Monday. This break in buying is unusual for Strategy, known for its consistent BTC acquisitions. The company last purchased Bitcoin on June 22, buying 520 BTC for approximately $34.9 million. Subsequently, from June 29 to July 5, it sold 3,588 BTC to raise about $216 million for funding preferred stock dividends and bolstering its dollar reserves. According to an SEC filing, as of July 26, Strategy holds 843,775 BTC, acquired at an average price of $75,476 per coin for a total of $63.69 billion. With Bitcoin currently trading around $63,200, the portfolio's estimated value is roughly $53.3 billion, representing an unrealized loss of about $10.4 billion. During the buying hiatus, Strategy has also increased its dollar reserves to $3.75 billion through common stock sales and launched the STRC share buyback program, strategic moves that have received analyst support.

Samson Mow, CEO of JAN3, shares five urgent recommendations for Coldcard users affected by losses due to a Random Number Generator (RNG) vulnerability. He emphasizes documenting all details (wallet addresses, dates, firmware versions, transaction info) for a proper incident report. Users are advised to file a police report with cybercrime units or agencies like the FBI's IC3 and to monitor coordinated efforts to track stolen funds. Mow strongly warns against destroying the affected Coldcard device or seed phrase, as they may be needed to prove ownership if stolen bitcoin is frozen on an exchange. He also cautions victims to ignore fraudulent recovery service offers that request upfront payments or sensitive wallet information. The incident highlights broader self-custody security lessons. Mow stresses minimizing single points of failure by using multi-vendor, multi-signature setups instead of relying on a single hardware provider. He acknowledges self-custody is complex and urges the community to be less critical of those using custodians or ETFs, as each storage method involves trade-offs. Coinkite, the maker of Coldcard, has issued a security advisory urging users of affected devices to update firmware, generate new seeds, and move funds if their seed was created on vulnerable versions. The aftermath includes potential legal action against Coinkite by affected users and an unsolicited blockchain message to the attacker offering money-laundering services.

Coldcard, a Bitcoin hardware wallet, faced a significant security breach a few days after Coinkite disclosed a long-undetected firmware vulnerability. The flaw allowed attackers to recover weakly generated wallet seeds, systematically draining vulnerable single-signature wallets. According to Coldcard Sweep Watch, total losses have reached approximately 1,359.882 BTC, with most stolen funds still concentrated on addresses controlled by the attacker. An unusual event occurred on August 1st when a transaction containing an OP_RETURN message was sent to one of the attacker's addresses. This message openly advertised money laundering services, offering help with KYC procedures and cashing out stolen coins for a 10% fee, and included a Telegram contact. This has led to speculation that it could be a serious offer, a trap, or possibly even law enforcement. Despite the theft of over 1,300 BTC, blockchain researchers note that the majority of the funds remain unmoved on a small number of addresses, making the stolen coins highly visible on Bitcoin's transparent ledger. In response, Coinkite released emergency firmware updates to fix the weak random number generator responsible for the vulnerability. However, the update only protects newly created wallets and does not fix seeds already generated by vulnerable versions. Furthermore, users began reporting that the update caused some Mk4 and Q devices (and some Mk3) to freeze, display errors, or become completely inoperable. Coinkite has not yet publicly confirmed a widespread firmware defect. Security experts are strongly advising users of potentially vulnerable wallets to move their funds to a new, securely generated wallet *before* applying any firmware update, as the patch cannot strengthen an already weak seed. This incident has evolved into a major test of trust in hardware wallet security, highlighting concerns about wallet design, seed generation, and long-term self-custody practices. The community is now closely watching to see if the stolen Bitcoin will be moved and if Coinkite will issue further guidance for affected customers.

The 2025 Bitcoin Nation-State Adoption Report by JAN3 highlights a paradigm shift, with national governments moving beyond corporate adoption to integrate Bitcoin into sovereign economic strategy. The report introduces the Bitcoin 20 (B20) Index, ranking countries by their engagement. The United States leads the ranking, followed by Bhutan, the United Kingdom, El Salvador, and the United Arab Emirates. Key developments include the US establishing a Strategic Bitcoin Reserve by presidential order, Bhutan monetizing excess hydropower for sovereign reserves, and El Salvador preparing to launch the world's first licensed crypto bank. This coordinated institutional adoption signals Bitcoin's transition to a recognized geopolitical tool for monetary sovereignty, financial security, and technological advantage in the global economy.
