A Chinese national dubbed the “Cryptoqueen,” who fled to London after orchestrating a staggering $5.6 billion (£4.2 billion) fraud, has been jailed for 11 years and eight months. Qian Zhimin, 47, was sentenced at Southwark Crown Court on Tuesday after pleading guilty to money laundering. Her scheme, one of the largest of its kind, targeted over 128,000 Chinese pensioners, whose life savings she converted into a mountain of Bitcoin.
Her conviction brings to an end a seven-year international manhunt that began with a massive Ponzi scheme in China and ended with her arrest in a quiet English city. Her accomplice, Malaysian national Seng Hok Ling, 47, was also jailed for four years and 11 months for his role in the operation.
The ‘Blue Sky’ Deception
Between 2014 and 2017, Qian masterminded a fraud in China through her company, Lantian Gerui, also known as “Blue Sky.” The company presented itself as a high-tech venture in cryptocurrency mining and health products.
Its target audience was primarily older adults, attempting to exploit their loneliness while assuring returns of as much as 300%. To foster trust, the operation adhered to a classic Ponzi scheme, providing small daily “earnings” to early investors, convincing many that it was safe to deposit their entire life savings even to the point of borrowing to invest more. In reality, Qian was embezzling the funds.
A New Life as a London Heiress
As Chinese authorities began to investigate in 2017, Qian fled the country. She arrived in the UK in September 2017 using a fake St. Kitts and Nevis passport under the alias Yadi Zhang. She quickly established a life of luxury, posing as a wealthy heiress in the jewelry and antiques trade.
She leased an opulent six-bedroom home in Hampstead, north London, for more than £17,000 a month; she engaged an assistant named Jian Wen to facilitate the transformation of her enormous, illegal Bitcoin wealth into cash, real estate, and other luxuries.
Extravagance and a Serious Error
While in London, Qian’s diaries disclosed her fanciful dreams. She mapped out a plan to purchase a castle in Sweden, befriend a duke from Britain, and be a self-proclaimed “queen” of between Croatia and Serbia, a self-proclaimed micronsation named Liberland.
But her attempts to bring her wealth into the legitimate financial system were her undoing. Qian, with Wen’s help, tried to purchase several ultra-high-value London properties, including one for £12.5 million. The purchases were repeatedly blocked by anti-money laundering and “know your customer” checks when her assistant couldn’t explain the source of the funds.
The UK’s Largest Crypto Seizure
The failed property deals triggered a Metropolitan Police investigation. In October 2018, officers raided the Hampstead mansion. Qian had already fled, but police seized several devices containing the keys to 61,000 Bitcoins.
At the time, the haul was valuable, but its worth has since exploded.
It is currently worth around £5 billion ($6.6 billion), representing the biggest cryptocurrency seizure in UK history. Qian, however, was still on the run and stayed free for almost another six years.
The Last Arrest in York
In April 2024, she was finally found at a rental house in the city of York. Police were led to her after she began using a dormant crypto wallet with the help of her new accomplice, Seng Hok Ling. When arrested, she was found with more illicit crypto wallets, false passports, and four illegally employed staff who were under contract to keep her identity secret.
At her sentencing, Judge Sally-Ann Hales described the scale of the money laundering as “unprecedented” and told Qian her motive was “one of pure greed.” The fate of the seized £5 billion in Bitcoin is now subject to civil proceedings, with thousands of her victims in China hoping to recover a fraction of their stolen savings.
