Crypto fraudster sentenced in UK after record $6B Bitcoin seizure

Policy & Regulation·November 13, 2025, 5:35 AM

As cryptocurrencies increasingly position themselves as a recognized asset class and potential hedge against fiat inflation, illicit activity tied to digital tokens is becoming more visible. A recent high-profile case in the UK has brought this issue into sharp focus, centering on a fraud scheme originating in China.

 

According to BBC News, the case involves Qian Zhimin, a woman who raised funds from more than 100,000 investors in China by claiming to operate a crypto mining company that also develops health products. Instead, she laundered the proceeds and fled the country. On Nov. 11, Qian was sentenced to 11 years and eight months in prison by a UK court.

$6B fraud and lavish lifestyle

​Qian entered Britain on a forged passport in September 2017 and proceeded to live an extravagant lifestyle, renting a mansion in Hampstead for over £17,000 ($22,700) per month. She was arrested in northern England in April 2024, and it was found that she held roughly 61,000 Bitcoin, valued at roughly £5 billion ($6.6 billion), having converted portions of her holdings to cover her substantial living expenses.

 

​The sheer scale of her wealth was revealed after police searched her rented residence, discovering the Bitcoin reserves on hard drives and laptops. It marks the largest crypto seizure ever recorded in the UK. During the raid, officers also found four other individuals at the property illegally employed to handle household tasks such as shopping, cleaning, and security.

 

​Since Qian’s arrival in the UK, the value of her Bitcoin holdings has appreciated more than 20-fold. With the fraudster now sentenced, victims are seeing a glimmer of hope for restitution. A civil case scheduled for early next year will determine the fate of the seized assets. However, while many defrauded Chinese investors are reportedly preparing to file claims, establishing a clear paper trail may prove difficult. Many victims routed funds through local intermediaries rather than transferring them directly to Qian’s firm.

 

​U.S. Bitcoin forfeiture and Beijing’s allegations

While the UK courts grapple with the aftermath of Qian’s fraud, a separate crypto controversy is brewing between the U.S. and China, highlighting Beijing's continued vigilance over the sector despite its 2021 ban on trading and mining. According to Cointelegraph, the state-supported National Computer Virus Emergency Response Center (CVERC) has alleged that American authorities are connected to the disappearance of roughly 127,000 Bitcoin, valued at around $14.5 billion, from the LuBian mining pool.

 

​These allegations surfaced after the U.S. filed a civil forfeiture claim in October against Chen Zhi, the Cambodia-based founder of the Prince Group, who is believed to have owned the assets prior to the breach. At the time of the filing, the U.S. Treasury Department noted that the funds were already under its control.

 

​CVERC contends that Washington hasn't explained how it accessed the assets. Citing data from analytics firm Arkham, the Chinese agency suggested the funds had been under U.S. control for over a year. They argued that the prolonged inactivity of the Bitcoin before the formal seizure is inconsistent with the typical behavior of hackers seeking quick profit, implying state-level involvement.

 

Economic chess between Washington and Beijing

This matter of Bitcoin control adds a new layer of complexity to U.S.–China relations, even as a trade truce between the two countries took effect on Nov. 10. In a report by CNBC, Washington cut tariffs on China’s fentanyl-linked imports to 10% and extended a reciprocal rate reduction under that agreement. In exchange, Beijing is said to have eased certain restrictions on rare earth exports. Analysts at Morgan Stanley suggest that China is maintaining its export-control regime, implemented in April, to retain strategic leverage. They caution that recurring negotiations and strategic divergence will remain defining features of the evolving bilateral relationship.

Almost 60K Korean Crypto-Holding Households Owe $389M in Unpaid Social Insurance Premiums

Almost 60K Korean Crypto-Holding Households Owe $389M in Unpaid Social Insurance PremiumsThe National Health Insurance Service (NHIS) in South Korea is intensifying its efforts to collect overdue premiums. Many high-income individuals who can afford to pay premiums for social insurance, including health insurance, have been neglecting their dues.Photo by Hush Naidoo Jade Photography on UnsplashVirtual assets for seizureAccording to the documents submitted on October 18 by the NHIS to lawmaker Jung Choun-sook, a member of the National Assembly’s Health and Welfare Committee, the NHIS is actively identifying a range of assets, including copyrights and virtual assets, that can be seized from these individuals. The NHIS aims to recover overdue premiums through stringent measures such as confiscation and government auctions. This move is designed to deter high-income earners from neglecting their obligations, ensuring fairness for those who consistently pay their premiums.Almost 60,000 crypto-holding householdsThis year, the NHIS discovered that 59,513 households, despite owning virtual assets, had outstanding social insurance premiums amounting to KRW 525 billion ($389 million). The NHIS has initiated collection efforts. In 2021, the insurance agency identified 5,336 households with virtual assets that had unpaid social insurance premiums totaling KRW 62.2 billion. Of this, the NHIS successfully collected KRW 6.92 billion, representing 11.13% of the total arrears.On this matter, lawmaker Jung highlighted that the government should strive to bolster the NHIS’s financial health. She underscored the importance of identifying concealed income sources or assets, like cryptocurrency holdings, of premium defaulters to ensure the collection of their overdue premiums.

Japan to implement crypto insider trading restrictions

According to a report published on March 31 by Nikkei, a Tokyo-based financial news outlet, the Japanese authorities are gearing up to categorize digital assets as financial products, while in the process broadening the scope of insider trading restrictions. While the publication didn’t cite a particular source, it reported that the Japanese Financial Services Agency (FSA) is expected to file a draft amendment related to the existing Financial Instruments and Exchange Act in 2026.Photo by M.S. Meeuwesen on UnsplashFrom payment to investment productCurrently, Japan’s Payment Services Act categorizes crypto assets as a means of settlement. That categorization looks at these assets from the perspective of a payment tool rather than considering them as investment products. The move is understood to be part of a broader effort to copper-fasten crypto sector oversight. Earlier this month, the Japanese cabinet approved a proposal that seeks to amend the Payment Services Act.  At the time, it had been suggested that the amendment would look to exclude crypto assets from being classified as securities, while also bringing about a reduction in the capital gains tax rate as it is applied to digital assets. It’s likely that crypto assets will find themselves in a distinct category, apart from securities like stocks and bonds. Crypto adoptionActivity related to crypto assets has been growing in Japan. 7.34 million active accounts were found to be responsible for crypto transactions in Japan in January. That amounts to a tripling in such crypto transaction activity over the course of five years. Japan enjoyed greater adoption at a very early stage in the global development of crypto. However, following the Mt. Gox crypto exchange collapse in 2014, which at the time accounted for the loss of 7% of Bitcoin’s supply, regulators responded by clamping down on the sector.  That situation led to greater investor protection for Japanese investors but it presented as a difficulty for Japan-based exchanges to compete globally with other exchange businesses overseas. A conservative stance taken by the FSA has also held back crypto exchange-traded fund (ETF) approval and adoption. Bitcoin ETFs were approved in the United States over a year ago. Earlier this month, Astar Network founder Sota Watanabe outlined that the current ruling party in Japan plans to remove crypto assets from a securities classification, alongside other changes which could potentially lead to the approval of crypto ETFs. The Liberal Democratic Party has also put forward crypto tax reforms that, if implemented, would see a 20% tax rate brought into effect where capital gains on digital assets are concerned.The finer detail with regard to the nature of insider trading restrictions as they will be applied to crypto assets has yet to be revealed. Nikkei speculated that such restrictions would likely be similar to those applied to conventional financial products. Last week, the Asia Web3 Alliance Japan, a crypto advocacy group, put forward a proposal to the U.S. Securities and Exchange Commission (SEC) that, if implemented, would see collaboration between the U.S. regulator and Japan’s FSA, its central bank and the Ministry of Economy, Trade and Industry. The objective of the proposal is to bring about cross-border regulatory clarity related to the further development of the Web3 ecosystem in both Japan and the U.S.

Short-Term Crypto Investment Prevails Among Hong Kong’s Retail Investors

Short-Term Crypto Investment Prevails Among Hong Kong’s Retail InvestorsHong Kong’s retail investor interest in virtual assets has experienced a significant surge in recent years, albeit a recent survey suggests that most retail investors take a short-term investment view relative to crypto assets.Photo by Robert Bye on UnsplashIFEC studyThis newfound enthusiasm for virtual assets emerges from a recent study published by the Investor and Financial Education Council (IFEC), a subsidiary of the Securities and Futures Commission (SFC), Hong Kong’s securities regulator. The survey found that 6% of retail investors in the city had entered the virtual asset market in 2023, as compared to merely 1% in 2019.Conducted from June to July of this year, the study encompassed 1,000 individuals aged between 18 and 69. The survey uncovered a trend toward crypto investing among retail investors who’ve been enticed by the allure of the emerging asset class. Intriguingly, every single one of the digital asset retail investors in the study held cryptocurrencies in their portfolios. Non-fungible tokens (NFTs) and stablecoins, while still relatively niche, were also present in the portfolios of 6% and 2% of investors, respectively.11% to invest in crypto within 12 monthsAnticipating a further uptick in interest, the IFEC report posits that 11% of those surveyed have intentions to invest in virtual assets or related products within the next 12 months. This indicates that the allure of virtual assets continues to exert its magnetic pull on investors in Hong Kong.Despite the growing interest, a noteworthy finding in the survey is that 75% of retail virtual asset investors admitted to their primary motivation being the pursuit of short-term gains. Simultaneously, 74% of these investors perceived virtual assets as a prevalent investment trend, and 73% cited the fear of missing out on popular investment opportunities as a driving factor. These statistics underscore the need for enhanced investor education within the sphere of virtual assets.Lack of regulatory awarenessAnother interesting aspect of the data which emerged from the survey was the finding that only 47% of all surveyed investors are aware of Hong Kong’s recently introduced virtual asset trading regulations, which came into effect on June 1.An additional facet of this investor behavior study was illuminated by research conducted by the Department of Applied Social Science at Hong Kong Polytechnic University (PolyU). This research, based on data from a separate IFEC report that surveyed 501 people from November to December of last year, revealed that many retail investors in virtual assets exhibited overconfidence in their judgment.These investors were also found to have a proclivity to overemphasize past information, lean heavily on readily available and easily recalled information, and overestimate personal intuition.With that in mind, Eric Chui, Head of PolyU’s Applied Social Science unit, advised virtual asset investors to adopt a more deliberate and rational approach. Chui emphasized the importance of building financial literacy and collecting high-quality market information to make informed investment decisions, while steering clear of irrational investment behavior and biases.
