According to Forbes, the scale of the theft in the Coldcard hardware wallet vulnerability incident has risen to approximately $130 million, involving about 2,000 BTC and over 5,200 addresses, reigniting the industry's debate over who should hold private keys. Data from Bitcoin Magazine shows that in the days following the incident, the net inflow into U.S. spot Bitcoin ETFs was $626 million, with some opinions suggesting that the vulnerability may drive more funds towards ETFs.Reports indicate that supporters of self-custody remain undeterred. Casa co-founder Jameson Lopp stated that confidence in self-custody should not be lost due to recent events, as custodial institutions also rely on random number generators. Bitcoin core early developer Peter Todd noted that the historical record of self-custody is far better than that of third parties. Another viewpoint argues that both reflexive choices have flaws. Onramp co-founder Michael Tanguma stated that if the only answer is Coinbase or ETFs, it poses a serious problem, as centralizing what should be decentralized assets undermines their foundation, advocating for a multi-institutional custody solution where keys are held by multiple regulated entities.

According to MBN, South Korea's People Power Party member Jeong Seong-guk plans to propose a bill to postpone the implementation date for taxing virtual asset income by three years, from January 1, 2027, to January 1, 2030. The member pointed out that by delaying the implementation date until a comprehensive review of related systems, including the taxation of virtual assets, is completed, a safeguard can be established to enhance taxpayer expectations and prevent system chaos.According to current regulations, starting from January 1 of next year, income generated from the transfer or lending of virtual assets will be classified as "other income" and will be subject to income tax. Therefore, the portion of annual profits exceeding 2.5 million won will be taxed at a rate of 22%, which includes 20% for other income tax and 2% for local income tax. Amid recent stock market turmoil and soaring real estate prices triggering public attacks on the government and ruling party, the People Power Party seems to be trying to gain public support by actively proposing legislation aimed at protecting the interests of virtual asset market investors. The People Power Party has consistently opposed the government, advocating for the abolition of this tax.

According to a report by Wall Street Journal, the AI fund Situational Awareness, which was previously disclosed to have suffered significant losses due to a sharp correction in AI-related stocks, is seeking new capital injection. However, the fund's experience of blowing up has not become a stain in Silicon Valley; instead, it has reinforced the "hero persona" of founder Leopold Aschenbrenner. Many Silicon Valley investors see it as an opportunity to "buy the dip" and continue to support this former OpenAI researcher turned investor. The fund has now informed investors that it will not accept new capital for the time being, but the enthusiasm from the outside has not waned. Senior venture capitalist Elad Gil even publicly announced his first application to invest in Aschenbrenner's fund.In addition, Morgan Stanley, which previously refused to provide prime brokerage services to Situational Awareness, has changed its stance and plans to include the fund as a prime brokerage client in the coming weeks.

We have not misappropriated assets, nor have we engaged in early withdrawals or evacuations; we have considered the involvement of courts and third-party auditing agencies to provide a transparent report."

According to Bloomberg, former OpenAI researcher Leopold Aschenbrenner's AI fund Situational Awareness has splurged $400 million this week to support a private company, which is the semiconductor manufacturing startup Source Foundry. It is reported that VC giant Sequoia Capital has also provided support for this startup. So far, representatives from Situational Awareness and Source Foundry have not responded to requests for comments, while Sequoia Capital has declined to confirm the hedge fund's investment situation.It is reported that Source Foundry is dedicated to developing a semiconductor manufacturing process that is simpler, cheaper, and faster than existing methods, aiming to bridge the widening gap between the demand for AI computing power and the capacity expansion of chip manufacturing. Analysts believe that Leopold Aschenbrenner's large-scale investment reflects the ongoing strong demand in the market for new chip manufacturing technologies, as AI developers' demand for computing power is increasing day by day. However, this investment also reveals that Situational Awareness has formed a highly concentrated risk exposure before facing significant financial pressure due to severe fluctuations in its publicly held technology positions.

The cryptocurrency hardware wallet manufacturer Coldcard has released an update on its customer data retention policy. Due to legal compliance requirements arising from the security incident disclosed on July 30, the company has temporarily suspended its original automatic customer data deletion mechanism.Previously, Coldcard's standard practice was to automatically clear customer records after 120 days, retaining only the user's email address and country information, while allowing customers to request early deletion of data at any time after product delivery. Coldcard stated that due to the security incident involving ongoing and potential legal proceedings, the company is obligated to retain records that may be relevant to litigation. Therefore, customer data that was originally scheduled for deletion will be temporarily retained until the law permits the resumption of normal processes.However, users can still request Coldcard to handle their personal information according to the original data retention policy. If users wish for their data not to be included in this legal retention scope, they can contact official customer service to make a request. Coldcard emphasizes that the retained data will be strictly protected, accessible only to authorized personnel, and will not be used for any purposes other than fulfilling legal obligations. The company will restore the previous automatic data deletion mechanism once legally permissible.

According to GoPlus monitoring, a user on the Base chain lost 500,000 USDC due to a phishing attack. When the attacker exchanged the stolen funds for WETH, the script did not set slippage protection, routing to a Uniswap V4 WETH/USDC pool with almost no liquidity, resulting in only 67.9 ETH (worth $129,000) being exchanged for 500,000 USDC, of which $370,000 was earned by an MEV bot.The MEV bot only paid 0.03 USDC to front-run the transaction but incurred 3.5 ETH in gas fees for this. Subsequently, the victim sent an on-chain message to the attacker and the MEV address, stating that they had identified the attacker and were willing to pay a 10% bounty for a refund.

According to Bloomberg, to advance the landmark cryptocurrency legislation "Clarity Act," bipartisan senators have proposed an ethical provision to Trump that may include a clause allowing the president to defer capital gains tax on his cryptocurrency assets. The proposal requires the president to divest from cryptocurrency-related businesses, and the relevant terms are still being negotiated between the White House and lawmakers. In June 2025, Trump reported that his family's cryptocurrency business generated over $1.4 billion in revenue, indicating that most of his income has come from digital assets benefiting from his own policies. Democratic senators have made strong ethical provisions a condition for supporting the bill, which aims to clarify the regulatory authority over the cryptocurrency industry.

According to TechCrunch, OpenAI is fighting back against Apple's lawsuit regarding the leak of trade secrets, stating that Apple itself has vulnerabilities in its information security management and employee departure processes, and cannot prove that the relevant information is protected trade secrets.Apple previously accused OpenAI of obtaining hardware-related secrets through former employees who left Apple and requested the court to expedite the evidence investigation. In the latest legal documents submitted, OpenAI stated that Apple allows employees to use personal iCloud accounts to handle work materials and did not promptly revoke access after employees left. OpenAI claimed that Apple did not specify the exact trade secrets that were allegedly stolen, but only referred generally to information such as product development processes, supply chains, and testing.OpenAI believes that Apple's lawsuit is more about restricting its development in the AI hardware field and denies that the company needs or uses Apple's trade secrets. The focus of the dispute between the two parties centers on employee mobility, intellectual property protection, and competition in the AI hardware sector.
