February 26th. According to crypto journalist Eleanor Terrett, the Office of the Comptroller of the Currency (OCC) today released a proposed rule implementing the GENIUS Act and is seeking public input.

February 26th, there were rumors that Chinese regulators were reviewing Jane Street's trading behavior in the Chinese ETF market. However, a source close to Jane Street said, "I have no knowledge of these rumors, nor any reason to believe they are true, and these rumors should not be associated with Jane Street." This week, Jane Street, its co-founder, and two employees were accused of insider trading, fraud, and market manipulation, behaviors that were also blamed for accelerating the collapse of the $40 billion market value of the 2022 TerraUSD (UST) stablecoin and its sister token Luna.Founded in 1999, Jane Street is one of the world's largest proprietary quantitative trading firms, with a net trading income of over $20 billion in 2024 and a net profit of nearly $13 billion. Unlike hedge funds, Jane Street does not accept external client funds, so its disclosure obligations are much lower than those of traditional asset management institutions, a structure that has kept it shrouded in mystery for a long time.

February 26, the joint release of the "Top Player" - A Deep Analysis of the Global Cryptocurrency Asset Harvesting Operation Under U.S. Technological Hegemony by the China National Computer Virus Emergency Response Center and other departments showcased the process of the U.S. harvesting global cryptocurrency assets using technological hegemony. According to incomplete statistics, from 2022 to 2025, the U.S. has cumulatively seized global cryptocurrency assets worth over 30 billion U.S. dollars through various cases, with the asset seizure scale in just the Chen Zhi case alone reaching 15 billion U.S. dollars, accounting for 50%.The report shows that in October 2025, the U.S. Eastern District of New York Federal Prosecutor's Office announced criminal charges against Chen Zhi, the founder of the Cambodian Prince Group, on charges including telecommunications network fraud, money laundering, etc., while prominently announcing the seizure of about 127,000 Bitcoins controlled by him, valued at about 15 billion U.S. dollars based on the market price at the time, setting a record for the largest virtual asset seizure in the history of the U.S. Department of Justice.The case of Binance founder Changpeng Zhao is another typical example of the U.S. using judicial hegemony and technological monitoring means to force global virtual asset platforms to comply with its regulatory rules, achieving economic harvesting and rule output. From 2023 to 2025, the U.S. initiated a "civil + criminal" dual accountability against Changpeng Zhao, and eventually, based on a plea agreement, Binance platform paid a fine of 4.3 billion U.S. dollars."During the case investigation, the U.S. used comprehensive technological monitoring means to achieve full penetration and evidence collection of Binance's operational data, user data, and transaction data, demonstrating its technological advantage in the field of digital asset platform monitoring." Dou Zhenhua further explained that the U.S. penetrated Binance's internal servers through hacking techniques, obtained core operational data and executive communication records, confirming that Binance executives were well aware of U.S. regulatory rules but intentionally evaded compliance requirements.

February 26th, the market speculation around Jane Street has once again triggered a discussion on the Bitcoin spot ETF trading mechanism. Analysts pointed out that the creation and redemption of spot ETF shares can be facilitated by Authorized Participants (APs) under a regulatory exemptive order framework, without necessarily requiring immediate buying or selling of Bitcoin on the open market; in cases such as futures contango, APs may also hedge through futures and other derivative products, leading to a timing mismatch between ETF fund inflows and spot market buying pressure and short-term price action.Reports cited industry insiders stating that the above mechanism is a common and legitimate operation of ETFs, and does not directly imply misconduct by any single institution, but it also reflects that Bitcoin price discovery is increasingly influenced by institutional trading venues (such as the futures market).
