Huobi HTX Chief Analyst Cloud stated that Bitcoin quickly rebounded after hitting the bottom under the dual pressure of interest rate hikes and the obstruction of the Clear Act, with a weekly increase of about 16%, rising to $87,307 during trading on September 21 (Huobi HTX spot price), reaching a new high since January. This round of increase is driven by three forces: the net inflow of about $1 billion into the U.S. spot Bitcoin ETF on September 21, the largest single day of the year; short positions being liquidated for about $650 million within 24 hours; and falling oil prices leading to a cooling of inflation expectations. Compared to last week's rebound, which was mainly driven by passive replenishment, this week saw a relay of spot buying.Whether the trend can continue depends on two points: whether ETF inflows can shift from a single-day pulse to a continuous trend, and whether leverage can be maintained at a non-overheated level. Currently, the funding rate is about 0.01%, in a neutral range, but the open interest of Bitcoin contracts has risen above $61 billion. If the capital weakens, high leverage will amplify the pullback. Market sentiment has entered an extreme greed zone, which historically has often been a precursor signal for short-term trend reversals. Technically, $87,500 is the resistance above, while the first support zone is between $84,000 and $85,000. The trend has conditions for continuation, but the highest risk of short-term volatility also occurs during the hottest phase of sentiment.Note: The content of this article is not investment advice and does not constitute any offer, solicitation, or recommendation of investment products.

According to statistics from Gaogong Robotics, in August of this year, there were a total of 168 winning projects disclosed in domestic bidding related to embodied intelligent robots, with a total amount of approximately 550 million yuan. Among them, products from Yushu Technology appeared in 55 procurement orders and 89 bids, accounting for about one-third, and ranked first in the number of winning bids with 136 medium/full-size humanoid and quadruped robots.In terms of amount, there were only 7 orders at the ten million yuan level, accounting for about 4%. The largest single order was for the "Shanxi Taichu Embodied Intelligent Innovation R&D Center Integrated Technology Operation Service Provider Project," amounting to 122 million yuan, used for the construction of a data collection and training center. In the overall orders, the amount for the data collection training center accounted for about 60%, while the projects flowing into scientific research and education accounted for nearly 80%. Projects directed towards real scenarios such as power inspection, industrial inspection, cultural tourism commercial use, and firefighting accounted for less than 10%.

Coinbase Chief Cryptographer Yehuda Lindell stated on the MARA Foundation TV program that the exchange is designing a custody system capable of adapting to any post-quantum signature scheme that Bitcoin may adopt in the future. It is currently unclear which post-quantum signature scheme Bitcoin will use in practical applications. Lindell believes it is unlikely that a single signature scheme will be universally adopted, so preparations must be made for different outcomes across various blockchains.Coinbase is custodian for approximately $250 billion in assets for institutions such as BlackRock. Traditional Multi-Party Computation (MPC) relies on key sharding, but many post-quantum signature schemes may be "not friendly to MPC"; for example, hash-based signatures lack the arithmetic structure required for traditional cryptographic key splitting. Although cryptographers like Dan Boneh are researching relevant solutions, this research is still in a highly experimental phase, and it remains uncertain whether a viable MPC-like solution for hash signatures can be developed.To this end, Coinbase is exploring a backup architecture centered around programmable Hardware Security Modules (HSM), where private keys will be encrypted with post-quantum cryptography and assembled only within physically secure HSMs. Lindell stated that while the completion timeline is uncertain, once finished, "I will be able to say, I can support any scheme," without worrying about a blockchain adopting a signature scheme that it cannot support.

White hat actors transferred 40.71 bitcoins related to the Coldcard vulnerability into a single transaction, valued at approximately 3.31 million dollars. This transaction aggregated funds from 11 addresses and included OP_RETURN information pointing to the Crypto Recovery Trust.Alex Thorn, head of Galaxy Research, revealed that a larger aggregation transferred a total of 52.37 bitcoins, involving multiple clusters of attacker addresses, accounting for about 2.8% of the funds involved in the vulnerability. A firmware flaw in Coldcard devices from March 2021 led to insufficient randomness in the mnemonic phrases, with the peak amount of funds involved being approximately 130 million dollars.

According to CoinDesk, Taylor Lindman, the Chief Legal Counsel of the U.S. Securities and Exchange Commission (SEC) Crypto Working Group, stated at the CoinDesk Policy & Regulation event held in Washington that the SEC is advancing rules for the custody of crypto assets. The relevant proposal has been submitted to the Office of Management and Budget (OMB) for review, covering investment companies and broker-dealers. She indicated that the rule aims to inform the market about how to hold non-securities crypto assets within broker-dealers without special registration and clarifies that investment advisors can store client assets in institutions such as state-chartered trusts.Once the proposal passes the review by the Office of Management and Budget, the SEC will formally present it and seek feedback from the industry and the public. Lindman also mentioned that the SEC will issue an employee statement in December 2025 as a transitional arrangement, guiding broker-dealers on handling crypto custody matters before the rules are implemented, and will allow investment advisors to store client assets in state-chartered trusts as qualified crypto custodians starting in September 2025.Lindman described the SEC's recent work as "laying the groundwork," including previously proposed rules allowing crypto issuance and exemptions for tokenized securities. She stated that the SEC is working to ensure that existing securities intermediaries and market participants can confidently use blockchain to hold and trade crypto assets. Previously, the SEC's attempts at custody rules under Gary Gensler in 2023 were abandoned, and a leadership supportive of crypto was appointed after the Trump administration took office.

In episode 166 of the BidClub podcast, chip designer Bubble boi stated that high-bandwidth flash is technically attractive but lacks decisive data center use cases. The information he provided indicated that the main customers he heard about are Chinese clients who find it difficult to obtain or produce high-end HBM.Bubble boi mentioned that HBF and high-end AI flash have a latency of about 5 microseconds, lower bandwidth than HBM, a lower cost per bit, but the total cost may be comparable. He believes the clearest customers are entities unable to obtain HBM, which aligns with the Chinese demand he heard from two to three people, as they cannot adequately manufacture accelerators or are willing to accept non-leading specification products.

According to Bloomberg on September 22, China's gold imports are at a record level this year, driven by falling international gold prices and a strengthening yuan. Customs data shows that the procurement volume has exceeded 1,000 tons as of August, surpassing the total for the entire year of 2025, with relevant customs data traceable back to 2017.Goldman Futures analyst Wu Zijie stated that strong investment demand has kept domestic gold prices at a slight premium relative to international benchmarks, thereby attracting imports.

On September 22, the Australian Treasury released the latest edition of the Intergenerational Report, which outlines a 40-year economic outlook and lists artificial intelligence as one of the five major transformations that will profoundly impact the economy in the future, but the report does not mention cryptocurrencies. The report states that AI systems have become "significantly" more autonomous, powerful, and widely applied, with some benchmark performances surpassing human levels. The other four transformations are geopolitical conflicts, an aging population, the transition to clean energy, and Australia's industrial shift towards the service sector.John O'Loghlen, National Director of Coinbase Australia, commented in an email that the report clearly indicates that Australia's prosperity over the next 40 years will largely depend on the ability to adopt new technologies and enhance productivity, but while the report focuses on artificial intelligence, it completely overlooks the financial infrastructure required for these agents. Previous Intergenerational Reports also did not address digital assets. Despite these omissions, the Reserve Bank of Australia has increased its focus on tokenized finance and upgrading financial infrastructure earlier this year, with the Digital Finance Cooperative Research Centre estimating that digital financial innovation could bring an economic benefit of AUD 24 billion (approximately USD 17.1 billion) annually.The Treasury also released a separate report on September 3 titled Financial Innovation Strategy, which discusses the connection between AI and financial infrastructure, stating that agent systems may increase automation and machine-to-machine trading, thereby creating greater demand for real-time, interoperable, and programmable payment systems.

According to The Information, citing informed sources, DeepSeek CEO Liang Wenfeng listed training large models with domestic chips such as those from Huawei as one of the company's biggest bets at the latest closed-door investor meeting, stating that this must succeed. DeepSeek expects to receive a new batch of Huawei chips for training as early as the fourth quarter of this year, although the specific models and quantities have not been disclosed.Liang Wenfeng believes that Huawei chips are expected to catch up with Nvidia in just a few years and hopes that DeepSeek will adapt to hardware beyond Nvidia in advance. DeepSeek is still using Nvidia chips to train models. In May of this year, Liang Wenfeng estimated that training the top-tier large models would require about 50,000 Nvidia GB300 chips, while switching to Huawei Ascend 950 would require about 200,000 chips, with the biggest issue at that time being insufficient supply from Huawei.

On September 18, the Office of the Comptroller of the Currency (OCC) granted preliminary conditional approval for the establishment of Catena Trust Bank, N.A. (under construction), a financial institution aimed at AI agents.Once full approval is obtained, the bank will provide custodial digital asset custody, investment management, and trust services under OCC supervision.

The U.S. Department of Justice announced that Iris Rabaya Au, a 37-year-old woman from Irvine, Orange County, California, was sentenced to 18 months in federal prison for failing to report over $2.6 million in illegal income to the Internal Revenue Service (IRS). She was also ordered to pay $1.484 million in restitution and had multiple luxury cars, high-performance vehicles, designer handbags, and three "Godfather" sculptures confiscated. Au is the ex-girlfriend of cryptocurrency scammer Adam Iza.Prosecutors stated that between 2020 and 2024, Iza fraudulently obtained Meta advertising accounts and credit lines, selling account access and earning millions of dollars in unreported income. At Iza's direction, Au set up shell companies and opened bank accounts, using the related funds to pay approximately $1 million to Los Angeles County Sheriff's Department (LASD) officers and to purchase or lease luxury homes, cars, jewelry, and clothing. They also spent nearly $10 million on entertainment and purchased about $16 million in cryptocurrency for Iza. Between 2020 and 2023, Au transferred over $2.6 million into her personal bank accounts but did not accurately report it on her federal tax returns. She pleaded guilty to one count of false tax return in March 2025. Iza pleaded guilty in January 2025 to charges including conspiracy to infringe rights, wire fraud, and tax evasion, with a sentencing hearing scheduled for October 5. He was also sentenced to 15 years in federal prison for his involvement in an attempted Bitcoin robbery and kidnapping case in Connecticut in August 2024.

Bitcoin News posted on the X platform stating that Spaces has launched "Trust Anchor," allowing applications to directly verify human-readable identities based on Bitcoin without relying on centralized servers.Users can obtain a single Trust ID and scan or paste it into Spaces-compatible applications to verify identity identifiers like alice@bitcoin based on the locally verified Spaces protocol status. The Trust ID is generated from the Bitcoin block header chain and the accumulated status of Spaces; the Veritas application on macOS can generate this ID without the need to run a full Bitcoin node, and users can also connect their own nodes or generate the same Trust ID through the Spaces client.This solution aims to use Bitcoin as the foundation for a decentralized certificate authority, enabling applications to authenticate identities without trusting company servers.

According to the monitoring by the head of Galaxy Research, the Coldcard white hat funds will come from the merger of 52.37 BTC from Wave 2, Footprints AA, AU, and AX into a new address, which recorded the OP_RETURN message "claim:cryptorecoverytrust dot com" in block number 967,948.These white hat funds account for 2.8% of the Coldcard vulnerability attack funds.

The Deputy Governor of the Central Bank of Russia, Vladimir Chistyukhin, stated that the country's cryptocurrency industry may have the necessary conditions to operate legally by the end of the year, with relevant regulations progressing as planned. According to the International News Agency, Chistyukhin mentioned that significant and large-scale secondary regulatory rules are currently being formulated, and the "fine-tuning" of internal rules is expected to be completed by the end of 2026.This year, Russia has continued to advance cryptocurrency legislation. President Putin signed a law in August that establishes a regulatory framework for digital currencies and digital rights, but the use of Bitcoin for payments remains prohibited. The central bank has approved the public to trade Bitcoin on the country's cryptocurrency exchanges, and non-qualified investors can purchase Bitcoin and other assets worth 300,000 rubles (approximately $3,582) through a single intermediary, while qualified investors face no restrictions.Russia's largest bank, Sberbank, plans to launch Bitcoin and cryptocurrency wallets and digital asset custody services in December. The bank expects that the trading volume of its new cryptocurrency business could reach 40 trillion rubles (approximately $4.7 billion) in its first year. Since 2022, Russia has prohibited the use of digital assets as a means of payment or legal tender, but lawmakers have made exceptions for international payments, likely aimed at circumventing Western sanctions. After the Russia-Ukraine conflict in 2022, the U.S. and Europe excluded Russia from the SWIFT system, and the Russian Finance Minister stated that the country's enterprises have been using Bitcoin to bypass related restrictions.
