NVIDIA today announced at SIGGRAPH 2026 that AI PC and AI workstation products equipped with RTX Spark chips are expected to launch as early as this fall. Developed jointly by NVIDIA and MediaTek (2454), the platform symbolizes that AI agents have officially extended from the cloud to edge devices. Whether on the brand side from companies such as ASUS and MSI or among other supply-chain vendors for cooling, high-speed connectivity, and power supply, many are expected to benefit.
RTX Spark AI PC to debut this fall—AI agents land on edge devices
Commercial Times reported that the next-generation AI systems based on RTX Spark will hit the market starting this fall, with ASUS (ASUS) and MSI named as the first brands to roll out products, followed by Acer (Acer) and GIGABYTE. This is not just a new product launch—it also signifies NVIDIA’s formal move to bring the computing architecture and environment for AI agents from data centers to edge devices such as AI PCs and AI workstations.

Grantham recently sharply criticized the SpaceX narrative and the premise of Bitcoin’s value.
Famed value-investing guru Jeremy Grantham warned four weeks ago, when he appeared on (Diary Of A CEO), that the market is in the biggest AI investment bubble in history. He also harshly criticized Elon Musk’s SpaceX Mars colonization plan as “nonsense,” while predicting that Bitcoin’s ultimate value will inevitably fall to zero.
The AI bubble could burst within a few years
In an appearance on (Diary Of A CEO), Grantham said that AI is a once-in-a-century major invention, whose importance is comparable to the internet.
However, the biggest bubbles in history are often accompanied by major technological breakthroughs. When capital flows in irrationally, it has already pushed the United States into the largest investment bubble in history.

BitMart announcement to stop operations; registrations and deposits will be halted starting July 26
Crypto exchange BitMart issued a “orderly shutdown” announcement on July 26, indicating that after evaluating the company’s operating conditions, the market environment, and future development directions, it has decided to gradually stop operating its trading platform. After the announcement was published, starting 09:30 on July 26, 2026 (UTC+8), the platform will progressively stop accepting new user registrations, and will also cease all digital asset and fiat deposit services. It reminds users that assets transferred after stopping deposits may not be credited automatically.

According to the latest report released by the U.S. National Crypto Currency Association (NCA), the U.S. cryptocurrency industry is expected to generate more than $55 billion in value in 2026, contributing to the country’s gross domestic product (GDP). Of this amount, approximately $31 billion will flow to workers in the form of wages.
This analytical report, carried out by the Pragmatic Policy Group (PPG) under a contract with the NCA and funded accordingly, states that although the U.S. cryptocurrency industry employs only 34,000 people directly, factoring in economic spillover effects such as the supply chain and employee consumption could support approximately 232,000 jobs in total.

The Department of Justice files five civil forfeiture actions to trace the money flows of transnational cryptocurrency scams
The U.S. Department of Justice announced that its Federal Prosecutor’s Office for the District of Washington has filed five civil forfeiture lawsuits targeting more than $25 million in cryptocurrency. The funds are alleged to be connected to transnational investment scams, romance scams, and “sextortion” follow-up scams. The cases are being investigated by the Washington Field Office of the U.S. Secret Service. The funds’ flow spans hundreds of cryptocurrency wallet addresses, and the victims are primarily located in the United States and Canada.
This operation is part of the "Scam Center Strike Force" initiative to combat scam centers. The initiative was established in November 2025. Its goals are to track down transnational scam groups, freeze illegal cryptocurrency assets, and assist victims in recovering their funds.

The Israeli AI director confirmed that it is currently lobbying TSMC, Samsung Electronics, and Intel to build advanced wafer fabs of 2 nanometers or below on-site, and plans to build a 100,000-GPU data center within five years. It aims to maintain its technological leadership in the Middle East in the AI race dominated by the US and China.
Name-checking TSMC, Samsung, and Intel! Israel pushes for a 2-nanometer advanced process
According to a report by Bloomberg, the director of Israel’s National AI Directorate said that it is actively lobbying TSMC, Samsung Electronics, and Intel to establish a semiconductor manufacturing cluster in Israel to produce the most advanced chips of 2 nanometers or below. The director said bluntly, “If we can’t get any of the companies’ advanced wafer fabs, I will consider it a major failure.” So far, spokespeople for the three fabs have not responded to this.

Strategy co-founder Michael Saylor has recently launched a fierce rebuttal of the Bitcoin community’s “blockchain cleanup crew” proposal. He warned that this upgrade plan, intended to curb the flooding of “junk data” on the Bitcoin blockchain, could change the most core operating principles of Bitcoin and even weaken its decentralization and neutrality.
The controversial proposal is named “Bitcoin Improvement Proposal BIP-110,” which argues for temporarily restricting the writing of arbitrary non-transaction data, so that Bitcoin can return to its pure monetary function. In response, Michael Saylor recently posted a lengthy piece on X titled (110 Reasons Why BIP-110 Is a Bad Idea), criticizing the proposal point by point. He said:

Hyperliquid is one of the most closely watched platforms in the on-chain derivatives market today. However, co-founder Jeff Yan said that he doesn’t usually spend much time watching data such as trading volume, market share, or liquidity.
In his view, if a trading platform only makes small optimizations to existing metrics, it may improve data in the short term, but it will be hard to build genuinely breakthrough products. Compared with day-to-day changes in trading volume, he cares more about functions that do not yet exist in the market—and whether Hyperliquid can continue to create “0 to 1” product progress.
Jeff Yan also discussed the market results of Hyperliquid’s newly proposed HIP-4. He believes that the next step for result markets is not necessarily only political, sports, or event prediction; more importantly, the key application could be on-chain options. By designing contracts that are fully collateralized with losses capped, it can help address the long-standing issues of liquidity and capital efficiency that on-chain options face.

Taishin Securities had another major screw-up four times this year; the Financial Supervisory Commission fined it NT$3.6 million.
The Financial Supervisory Commission has recently issued a decision notice, fining Taishin Securities NT$3.6 million. This sets a record for the largest fine in the history of securities brokers.
According to the decision notice, prior to the merger with Yuanta Securities on April 6 of this year, Taishin Securities did not properly conduct information system planning and testing, resulting in multiple major cybersecurity incidents after the merger. It also failed to fully implement internal control systems, in violation of Article 2, Paragraph 2 of the securities firm management regulations.
Looking back at the history of incidents after Taishin Securities’ merger, on April 7, 14, 20, and May 21 there were electronic trading system malfunctions that triggered widespread public complaints; at the time, the Financial Supervisory Commission and the Taiwan Stock Exchange both intervened to handle the matter.

With the Senate schedule running out of time, the likelihood of completing a vote by August has declined
The U.S. crypto market structure bill, the “Clarity Act,” was originally viewed by the industry as the most critical regulatory breakthrough for 2026. However, in his latest remarks, Senate Majority Leader John Thune has made it clear that the odds of passing the bill before Congress’s summer recess have dropped significantly. Industry and congressional negotiation representatives previously set August 7 as an important deadline—if they could complete a vote before senators leave Washington, the bill still had a relatively high chance of finishing the legislative process this year. Now, that window is narrowing rapidly.

Ahead of Coinbase’s earnings report next week, the largest crypto exchange in the U.S. (U.S. stock ticker COIN), the research firm Benchmark made the first move. Citing a recent cooldown in crypto trading, it lowered its earnings forecast for Coinbase’s second quarter, while still maintaining a “Buy” rating and a $270 target price. The analysts believe that, compared with the weakness in a single quarter’s earnings, the potential upside from the U.S. Digital Assets Clarity Act becoming law is the real catalyst that could trigger a surge in the stock price.

Brazil’s first “on-chain livestock mortgage loan” emerges
At a farm in Engenho Velho, Enge-nhe Nuvei Luu, Paraná, Brazil (Fazenda Engenho Velho), recently 10 dairy cows worth 120,000 reais (about 600,000 TWD) were used as collateral to successfully secure a loan of 100,000 reais. This is also the first financing case in the history of the Brazilian stock exchange (B3) that was formally registered using “tokenized live livestock” as collateral.
The process of turning dairy cows into tokens and trading them is as follows: the farm owner issues Brazilian agricultural receivables bonds certificates (CPR-F) to the credit company BMP, then BMP transfers the receivables to the Target FIDC fund, and registration is completed on the B3 stock exchange.

A coalition of nine institutions formed, investing $15 million over three years
A further step in the institutionalization of Bitcoin. This time, the focus shifts from ETFs, treasury management, and trading platforms to underlying security defenses. BlackRock, Coinbase, Strategy, Anchorage Digital, ARK Invest, Block, Blockstream, Fidelity Digital Assets, and Galaxy—nine institutions—jointly formed the Bitcoin Security Consortium. They pledged to invest a total of $15 million over the next three years to support Bitcoin security research and open-source development.

Traditional asset management giant Franklin Templeton, which manages nearly $1.8 trillion in assets, believes that agentic AI will become a “killer application” driving the mass adoption of blockchain. In an official article published on July 22 by Sandy Kaul, the company’s head of digital assets and innovation, he argues: “Blockchain will play a key role in unlocking the consumer-transaction potential of agentic AI, and the growth of agentic AI is likely to become the ‘killer’ application that drives blockchain adoption.”

South Korean stocks plunge rapidly during the trading session, triggering a trading halt for the tenth consecutive day.
Affected by multiple negative factors and deleveraging, the South Korean stock market triggered the circuit breaker mechanism again today (7/24). This is the 10th consecutive trading day the circuit breaker has been activated in Korea. Taiwan’s stock market has also not been spared: during the session it plunged by more than 1,200 points, falling directly below both the quarterly moving average line and the 44,000-point level.
South Korean stocks opened lower and moved down today, with both the KOSPI and KOSDAQ indices triggering the “sell-side circuit breaker mechanism.” By midday, the KOSPI had plunged more than 5% to around 6,700 points, and the KOSDAQ was also down nearly 5%.
This is the 21st time this year that the South Korean stock market has activated a sell-side circuit breaker. If you add the buy-side circuit breakers, the total for the year reaches 41 times.

Goldman publicly supports the bill; Solomon says the market needs clear rules
Goldman Sachs CEO David Solomon recently publicly stated his support for advancing the (CLARITY bill), causing a clear split in major Wall Street banks’ positions on crypto regulation.
Solomon said that while the bill still has many details to be discussed, its key value lies in establishing a more stable regulatory framework so the digital asset market can develop under clearer rules. He also emphasized that the U.S. needs to first build market structure before it can drive innovative processes.
The focus of the (CLARITY bill) is to clarify the division of responsibilities between the SEC and the CFTC in the digital asset market. The draft would define which assets may be considered digital commodities, which should still fall under the securities law framework, and give the CFTC broader authority to regulate spot digital commodity markets. For large financial institutions like Goldman to expand tokenized assets, crypto custody, institutional trading, or on-chain financial services, they also need to clearly understand regulatory authority and responsibility, capital requirements, and customer protection standards.

Bitcoin falls below $65,000, risk assets come under pressure at the same time
Bitcoin ($BTC) briefly slipped below the $65,000 level yesterday. During the session, it even dipped to around $64,800, with a nearly 2% decline over the past 24 hours. This pullback came after a brief attempt to challenge $67,000 earlier in the week, suggesting that the buying pressure was unable to sustain the breakout momentum. Major crypto assets such as Ethereum ($ETH), $SOL, and $XRP weakened in sync, and the market returned to a risk-off sentiment regime.

U.S. stocks also saw notable selling pressure the same day: the Nasdaq fell by about 2.2%, the S&P 500 dropped by about 1.2%, and the Dow Jones Industrial Average plunged by more than 500 points. In recent years, Bitcoin has been viewed by some investors as an inflation hedge and a safe-haven asset, but short-term trading is still heavily influenced by risk appetite, U.S. dollar liquidity, and interest-rate expectations. When tariffs, oil prices, and geopolitical tensions all intensify at the same time, the crypto market quickly shows signs of leverage unwinding and the risk of long-position liquidations.

AMD’s first Helios AI rack officially enters full-scale mass production
Semiconductor giant Advanced Micro Devices (AMD) officially announced at its annual Advancing AI conference that its first Helios rack-level AI solution has entered full-scale mass production. “Suma” CEO Lisa Su personally took the stage to introduce the new system’s performance and customer roadmap. Meanwhile, among the partnership ecosystem list shown on the event’s backplate, several Taiwanese supply-chain companies appeared, immediately becoming the focus of investors’ attention.

Global stablecoin issuer Circle continues to accelerate its expansion in Asia. Circle announced that it has signed memorandums of understanding (MOUs) separately with Korean tech giant Kakao Group and Toss, one of South Korea’s largest fintech platforms, further promoting the rollout of USDC in the Korean payments market.
Teaming up with Kakao Group to explore USDC and the global payments network
According to news released by Circle, the company has reached a cooperation with Kakao Group. The two sides will jointly explore payment infrastructure and digital asset technology based on blockchain.
Kakao Group owns major financial services such as Kakao Pay and Kakao Bank, and also operates an ecosystem spanning social, payments, e-commerce, and content. It is regarded as one of South Korea’s most influential digital platforms. If the cooperation is further implemented in the future, it could enable USDC to reach a wider range of Korean consumers and business payment scenarios.

According to a CoinDesk report, multiple attacks targeting cryptocurrency protocols occurred in succession within hours on July 23. The attacks involved four protocols in the Bitcoin and Ethereum ecosystems, with total losses exceeding $35 million. Security firms BlockAid and PeckShield, along with on-chain analytics firm Lookonchain, tracked the related fund flows; the biggest loss was from the derivatives protocol AFX Trade on Arbitrum.
AFX Trade bridge private key leak, $24 million drained
AFX Trade built on Arbitrum was the hardest hit in this wave of attacks. According to security firm BlockAid, the attackers obtained the private key for the protocol’s cross-chain bridge, allowing them to transfer out approximately $24 million in assets. Once the private key lands in the attackers’ hands, it effectively gives them the keys to the vault, making it nearly impossible for users’ funds to be stopped in real time.
