Zhimin Qian (alias Yadi Zhang), a Chinese businesswoman, faces up to 14 years in prison as the UK seized more than 61,000 Bitcoins—worth over $6 billion—in what authorities call the largest cryptocurrency seizure in history.

Police monitored Ling, leading to Qian’s arrest in April 2024; authorities also seized £11 million in cash, gold, and cryptocurrencies during the investigation.

Public events promoted by Qian attracted non-sophisticated investors with claims of government support, leading to substantial financial and personal losses for victims and their families.

Investors were drawn in at public events with promises of government backing, and many non-experts suffered large losses after promised returns ceased in 2017, with civil proceedings in the London High Court seeking compensation.

Legal experts describe the case as exceptionally large in scale, noting that many unsophisticated investors were misled about government involvement or legitimacy.

Bitcoin’s value surged from about $3,600 at the end of 2018 to roughly $100,000 at the time of reporting, highlighting the asset’s scale and potential impact on victims and markets.

The period saw Bitcoin’s price move dramatically, rising from around $3,600 in late 2018 to about $100,000 during the coverage.

Two accomplices are linked to the case: Seng Hok Ling, a Malaysian national who admitted money laundering and awaits sentencing, and Jian Wen, jailed for six years and eight months last year for involvement, with Bitcoin wallets valued at over $2 billion.

Co-defendants include Seng Hok Ling, who admitted money laundering and faces sentencing, and Jian Wen, sentenced to six years and eight months for involvement with Bitcoin wallets valued over $2 billion.

Seng Hok Ling is a Malaysian accomplice who admitted money laundering and awaits sentencing; Jian Wen was convicted last year and imprisoned for more than six years for ties to Bitcoin wallets worth over $2 billion.

Legal commentators say the case could rank as one of the largest criminal cases by value involving an individual rather than a corporation, underscoring its severity.

The narrative emphasizes the human toll, with families and individuals—such as a Chinese couple in their 40s—suffering substantial losses and personal disruption.

Qian coordinated a Ponzi-style scheme in China from 2014 to 2017 that defrauded more than 128,000 victims, with illegally obtained funds converted to Bitcoin and laundered in the UK via property purchases, including a £23 million London mansion.

Qian fled China in 2018 using false documents and later sought to launder proceeds in the UK; she pleaded guilty to acquiring and possessing criminal property and awaits sentencing after a two-day London hearing.

From 2014 to 2017, Qian defrauded more than 128,000 victims in a Ponzi-like scheme, then escaped to the UK in 2018 and attempted to launder proceeds.

Civil proceedings in London have drawn around 1,300 alleged victims, with compensation schemes still being debated in the High Court.

Victims described serious personal losses, including impacts on retirement savings and family stability following a 2016 presentation promoting the scheme.

Experts characterize the case as potentially the largest of its kind by value involving an individual, with victims enduring substantial personal and financial harm and some families experiencing strain or separation.

Authorities had previously seized more than 61,000 Bitcoins, valued at over $6 billion, in what police called the largest cryptocurrency seizure ever, aiding the case against Qian and her network.
