According to a report by Reuters, influenced by multiple factors such as the tense Sino-U.S. relations, China's push for domestic software alternatives, and U.S. export controls, Microsoft has closed at least 15 branches and joint ventures in China over the past five years, executing a strategic contraction. In 2023, the company internally considered exiting the Chinese market, as some executives believed that "the geopolitical risks outweighed the limited economic returns," but ultimately did not proceed with the exit. Microsoft disclosed in 2024 that its business in China accounted for only about 1.5% of its global revenue.The report states that Microsoft's final decision to remain in China was primarily due to the establishment of a profitable path—providing Azure cloud and AI services to Chinese companies like ByteDance and Shein, helping them operate compliantly in overseas markets. Additionally, the company believes that retaining its business in China remains strategically significant for acquiring engineering talent. However, analysts question the sustainability of this AI business model: the service relies on third-party models like OpenAI, and Chinese companies are increasingly adopting domestic alternatives like Kimi, which offer comparable performance at lower costs.Microsoft's research and development presence in China is also contracting. Its predecessor, Microsoft Research Asia, has successively established new labs in Vancouver, Singapore, and Tokyo. In 2024, the company offered job opportunities to 1,000 top engineers to relocate to the U.S. and three other countries, but only about one-third accepted, with most senior engineers moving to domestic universities and tech companies. A Microsoft spokesperson responded that the company will continue to commit to the Chinese market but did not comment on specific decision details. ByteDance and Shein did not respond to related inquiries.

According to Lookonchain, the whale address "TLBL" has once again experienced a significant asset security incident, with total losses exceeding $50 million.Previously, this address lost approximately $24 million due to a phishing attack two years ago; in the latest incident, it is suspected that over $26 million in assets from three wallets were completely transferred out due to a private key leak. This incident has once again raised market concerns about the security management risks of high-net-worth on-chain addresses.

HashKey has become the authorized distributor of the Anchorpoint Hong Kong Dollar stablecoin HKDAP, launched beta testing, and completed the first minting and redemption transaction.

According to Cointelegraph, Mauro Eldritch, the founder of cybersecurity company BCA LTD, and Heiner García, a network threat intelligence analyst at Telefónica Tech, jointly established a fake cryptocurrency startup "Ballena Azul," successfully luring suspected North Korean IT workers to work in a controlled virtual desktop environment for up to five weeks while monitoring their behavior throughout.Investigations show that the external servers used by the workers are linked to North Korean cyber operations that previously distributed malware such as InvisibleFerret, BeaverTail, and OtterCookie; the workers also heavily relied on ChatGPT for programming assistance and Google Gemini to forge identity documents. Researchers pointed out that North Korean IT workers obtained remote jobs by faking U.S. identities, with their earnings ultimately flowing into Pyongyang's weapons of mass destruction programs. According to the U.S. Treasury Department, such programs are expected to generate nearly $800 million for North Korea in 2024.

Crypto journalist Eleanor Terrett posted on the X platform that although the U.S. Senate has postponed the key procedural vote on the CLARITY Act until September, regulators are preparing to advance their own cryptocurrency issuance rules framework. The Senate previously failed to complete the procedural vote on the CLARITY Act, and the related agenda has been postponed until September. Senate Majority Leader John Thune has submitted a procedural motion, and a new voting window is expected around mid-September.Meanwhile, the U.S. Securities and Exchange Commission (SEC) is preparing a new rule proposal for cryptocurrency asset issuance activities. Market participants believe that even if the legislative process for the CLARITY Act is delayed, regulators may still push for digital asset market structure reform through administrative rules.Analysts point out that in the coming months, the U.S. crypto regulatory path may see a "dual-track advancement": on one hand, Congress continues to push market structure legislation like the CLARITY Act; on the other hand, the SEC may establish a regulatory framework for token issuance, trading platforms, and digital asset service providers through rulemaking.

Economists say that the mixed July employment report released last week has heightened the importance of inflation data. LPL Financial Chief Economist Jeffrey Roach pointed out that the path of the Federal Reserve's interest rate hikes will depend on how long inflation remains elevated.Vanguard analyst Hicklin believes that the July employment report and the expected improvement in inflation will strengthen the Federal Reserve's reasons to hold steady before the end of the year. Recent data releases have bolstered market confidence that the Federal Reserve will keep interest rates unchanged this year.

Web3 security company CertiK released the report "Intel3D: PSAV and Brazil's New Security Standards." The article points out that as the deadline for authorization applications set by the Central Bank of Brazil (October 30 of this year) approaches, local virtual asset service providers (PSAV) are facing a round of concentrated compliance adjustments, and compliance and security certifications issued by independent third parties are transitioning from industry best practices to important requirements for market access.According to the report, CertiK is currently conducting independent external audits based on the Central Bank of Brazil's Normative Instruction No. 701. As one of the markets with the highest adoption of crypto assets globally, the impact of this regulatory transformation in Brazil may far exceed the local market. The report shows that Brazil currently ranks fifth in the world for actual crypto asset adoption rates. From June 2024 to June 2025, the on-chain asset value received by Brazil reached $318.8 billion, accounting for nearly one-third of on-chain activity in South America during the same period. Stablecoins have become an important infrastructure in the local digital asset market, accounting for about 80% of the trading volume in crypto asset transactions reported to the Federal Revenue of Brazil.

Bitcoin News posted on the X platform that Bitcoin developers have launched a new visualization tool to explain how entropy works and how to generate randomness for Bitcoin private keys.The tool covers true random number generators (TRNG), pseudo-random number generators (PRNG), rolling dice, and flipping coins.

A wallet security incident involving approximately $130 million in Bitcoin losses is reigniting discussions in the crypto industry about asset custody models: should Bitcoin holders rely on personal self-custody or turn to institutional custody? Hardware wallet manufacturer Coldcard had a vulnerability in its firmware in 2021 that led to some mnemonic phrases generated by the device being predictably risky. This vulnerability was discovered years later, and approximately 5,200 addresses and about 2,000 BTC have been stolen, with losses amounting to around $130 million.After the incident, some investors began to turn to Wall Street custody products. Data shows that the U.S. spot Bitcoin ETF saw a net inflow of about $626 million within days of the incident. Bloomberg ETF analyst Eric Balchunas stated that such security incidents could further drive funds into ETFs. However, the Bitcoin core community still insists on the self-custody concept. Casa co-founder Jameson Lopp stated that recent events should not undermine users' confidence in self-custody and pointed out that third-party custody also carries risks. Bitcoin Core early developer Peter Todd also believes that self-custody has a better long-term safety record than centralized institutions.Onramp co-founder Michael Tanguma believes that both options have flaws. He stated that concentrating a large amount of assets in a single institution creates a "honey pot," while hardware wallets face risks related to supply chains, firmware, and random number generation. Tanguma proposed a "multi-institution custody" solution, where multiple regulated institutions hold keys through a multi-signature mechanism, requiring multiple institutions to jointly sign any transaction to reduce single points of failure. However, this model has also sparked controversy. Critics argue that while multi-institution custody enhances security, it also introduces permissioned management, conflicting with the decentralized ideals originally pursued by Bitcoin. As Bitcoin gradually enters the fields of pensions, trusts, and institutional asset allocation, the industry is seeking new custody solutions suitable for long-term wealth management. The Coldcard vulnerability incident once again highlights that achieving a balance between security, decentralization, and usability remains a core challenge facing the Bitcoin ecosystem.

Christopher Smith, founder of the blockchain startup Quantus, stated that the first quantum attack may manifest as a series of unexplained thefts of cryptocurrency wallets, rather than directly stealing the approximately $63 billion worth of dormant Bitcoin expected from Satoshi Nakamoto. He pointed out that sufficiently powerful quantum computers could derive private keys from public keys exposed on the blockchain, allowing attackers to transfer funds without needing to breach wallets, devices, or internal systems of exchanges.In theft incidents at highly secure institutions, the only forensic evidence may be the absence of intrusion traces. Smith indicated that the initial targets of quantum attacks could be military systems and national secrets; in the blockchain space, the minting keys of stablecoin issuer Tether may be of greater value. Attackers could mint tokens out of thin air through managed wallets and sell them off before the issuer responds. Google has accelerated its post-quantum migration timeline to 2029; Smith believes the probability of quantum computers breaking modern cryptography around 2028 is "50-50." Relevant blockchains have begun migrating to post-quantum signatures.

Renowned trader Killa expressed his technical analysis on Bitcoin, stating that if Bitcoin falls below the current weekly high (65,300 USD), it will retrace to test the monthly opening price of around 62,700 USD. However, if it can strongly break through and stay above the resistance level of 65,300 USD, it may further rise to around 66,900 USD.Overall, the judgment is that the market has been in a consolidation range for the past two months, with no obvious breakout signals. Killa, as a quantitative trader focused on BTC, predicted the peak of this bull market in May 2025 and has over 200,000 followers on platform X. In mid-April, he shorted Bitcoin at 74,688 USD and switched to long during the market-wide decline on June 5.

Wall Street Journal reporter Nick Timiraos stated that for the Federal Reserve, the July employment report will be a difficult data set to interpret. New evidence that the labor market has not re-accelerated may weaken the urgency for a rate hike next month, but this still depends on better inflation data.The decline in the unemployment rate will continue to keep the market focused on inflation data. Whether price pressures are rising or falling will determine if more officials conclude that they cannot maintain their inflation target forecasts with interest rates unchanged. A moderate inflation report will strengthen the rationale for keeping rates unchanged (as two consecutive months of moderate data begin to show a trend rather than noise). Conversely, strong data would call the forecasts into question again and give officials opposing a rate hike the opportunity to seek a fourth vote in favor.

Vangrid announced the completion of a $9 million seed round financing, with participation from HashKey, Borderless, Crypto.com Capital, Animoca Brands, Gate Labs, and Mapleblock Capital.The main business of the project is to collect spatial data, where users collect geographic location data through smartphones and receive rewards.

According to Fortune magazine, Michael Saylor, Executive Chairman of Bitcoin treasury company Strategy, stated that artificial intelligence is changing the way wealth is created, and businesses and individuals should not try to compete with machines but should leverage AI to amplify their own capabilities. In an interview, Saylor mentioned that he used ChatGPT to help Strategy design a preferred stock financing plan based on Bitcoin, ultimately enabling the company to raise about $15 billion through an IPO and related financing. He stated, "AI helped me create $15 billion."Saylor believes that the core advantage of the AI era is not to repeatedly execute tasks that machines can accomplish, but to ask better questions and use AI to explore new opportunities that were previously unattainable. "Don't try to work harder than robots." In recent years, Saylor has pushed Strategy to allocate Bitcoin on a large scale, transforming the company from a traditional software enterprise into a publicly traded company with Bitcoin as its core asset. Although this strategy comes with higher risks, Saylor stated that significant innovations often require enduring volatility and continuously adjusting direction. He noted that the successful entrepreneurs of the future will be those who can combine AI with human creativity, rather than individuals trying to replace AI in completing tasks.

According to Slow Fog monitoring, MistEye detected a large-scale npm supply chain attack affecting the Keyv/Cacheable ecosystem. The attackers published over 2,000 malicious package versions, including keyv@6.0. Keyv is a widely used key-value storage abstraction library that supports backends such as Redis, SQLite, PostgreSQL, and MongoDB, with approximately 127 million downloads per week, leading to significant downstream supply chain exposure.The attack method is highly similar to the previous Shai-Hulud npm worm activity, indicating a highly automated and scalable supply chain attack. Potential attack behaviors include credential theft, environment variable leakage, CI/CD key leakage, remote payload delivery, and lateral propagation through compromised development environments. Security teams should immediately identify and remove affected package versions, upgrade to verified secure versions, review dependency lock files and build logs, monitor suspicious external connections, rotate leaked credentials, and rebuild environments upon confirmation of the impact.
