LONDON (AP) — A Chinese woman who was found with 5 billion pounds ($6.6 billion) in Bitcoin after defrauding more than 128,000 people in China in a Ponzi scheme was sentenced by a U.K. court on Tuesday to over 11 years in prison.

Police said the investigation into Zhimin Qian, 47, led to officers recovering devices holding 61,000 Bitcoin in the largest cryptocurrency seizure in the U.K.

Qian, dubbed “cryptoqueen” by British media, was arrested in April 2024 after spending years evading the authorities and living an “extravagant” lifestyle in Europe, staying in luxury hotels across the continent and buying fine jewelry and watches, prosecutors said.

Police said she ran a pyramid scheme that lured more than 128,000 people to invest in her business between 2014 and 2017, including many who invested their life savings and pensions. Authorities said she stored the illegally obtained funds in Bitcoin assets.

When she attracted the attention of Chinese authorities, Qian fled to the U.K. under a fake identity. Once in London, police said she rented a “lavish” house for over 17,000 pounds ($23,000) per month.

Investigators found notes Qian had written documenting her aspirations — including her “intention to become the monarch of Liberland, a self-proclaimed country consisting of a strip of land between Croatia and Serbia.”

The businesswoman, who had pleaded guilty to money laundering offenses and transferring and possessing criminal property, was sentenced Tuesday to 11 years and eight months at Southwark Crown Court.

She was sentenced alongside her accomplice Seng Hok Ling, 47, a Malaysian national who was accused of helping Qian transfer and launder the cryptocurrency. Ling was jailed at the same court for four years and 11 months after he pleaded guilty to one count of transferring criminal property.
