Bitcoin News Today: Chinese Retirees Scammed by £4.6B Crypto Ponzi Scheme, Architect Sentenced to 11 Years in UK Landmark Case

The UK has sentenced Qian Zhimin, a Chinese national, to 11 years and eight months in prison for orchestrating a vast Ponzi scheme that defrauded over 128,000 investors in China and laundering the proceeds into Bitcoin worth billions of dollars. The case, which involved the seizure of 61,000 BTC-currently valued at approximately $5–6 billion-marks the largest cryptocurrency seizure in UK history and one of the most complex economic crime investigations ever conducted by British authorities according to reports.

Qian, also known as Yadi Zhang, was convicted of money laundering and possessing illegally obtained cryptocurrency after pleading guilty in September 2025. Judge Sally-Ann Hales at Southwark Crown Court condemned her as the "architect of this offending from its inception to its conclusion," emphasizing her "pure greed" as the driving force behind the fraud according to court records.

Between 2014 and 2017, Qian's company, Lantian Gerui, lured investors with promises of high returns from cryptocurrency mining and health tech ventures. Prosecutors allege the scheme defrauded victims of roughly £4.6 billion ($6.3 billion), with a significant portion siphoned into Bitcoin according to prosecutors.

The investigation, led by the Metropolitan Police's Economic and Cybercrime Command, uncovered Qian's lavish lifestyle as she fled China in 2017 and evaded authorities for years. She rented a £17,000-per-month mansion in London's Hampstead and attempted to purchase luxury properties, triggering scrutiny from regulators. Police seized devices containing 61,000 BTC during a 2020 raid on her home, and Qian was arrested in April 2024 alongside her accomplice, Senghok Ling, a Malaysian national. Ling was sentenced to four years and 11 months for aiding in the laundering of cryptocurrency according to court documents.

The scale of the fraud and its global implications have drawn widespread attention. Will Lyne, head of the Met's cybercrime unit, called it "the largest money laundering case in UK history by value" according to officials. Chinese victims, many of whom were retirees, invested life savings under the guise of patriotic initiatives, only to lose everything when payments ceased. One investor described how the scheme exploited trust in figures like Mao Zedong's son-in-law, who was falsely portrayed as a supporter according to victim testimony.

Qian's arrest and sentencing have sparked hope among victims, though recovering funds remains complex. The UK government will likely handle unclaimed proceeds, raising questions about compensation for investors. Legal experts note that proving individual claims will be challenging, particularly for those who funneled money through local promoters. Meanwhile, Qian's grandiose plans-detailed in seized documents-reveal ambitions to establish an international bank, acquire a Swedish castle, and even become "queen" of Liberland, a micronation in Europe according to seized documents.

The case underscores the growing challenges of tracking illicit cryptocurrency activity. Authorities praised the collaboration between UK and Chinese law enforcement, though Qian's use of false identities and international travel highlighted gaps in cross-border oversight. As Bitcoin's value has surged since the fraud's inception, the seized assets now represent a windfall for regulators, though victims continue to grapple with the aftermath of a scheme that preyed on trust and technological optimism according to financial analysts.
