A Chinese woman who led one of the largest Ponzi schemes in crypto history now faces up to 14 years in a UK prison after authorities uncovered a staggering $6 billion in stolen Bitcoin.
Key Takeaways
- Zhimin Qian, also known as Yadi Zhang, pleaded guilty to possessing and laundering criminal property in the UK.
- UK authorities seized over 61,000 Bitcoins, valued at more than $6 billion, marking Britain’s largest crypto-related seizure.
- The Ponzi scheme, which ran between 2014 and 2017, defrauded more than 128,000 victims, primarily in China.
- Qian attempted to launder the stolen funds in the UK through luxury real estate purchases, including a $30 million mansion.
What Happened?
Zhimin Qian orchestrated a fraudulent investment scheme in China that promised high returns but turned out to be a classic Ponzi setup. She later converted the stolen funds into Bitcoin and fled to the UK using false identification documents. Her capture led to one of the biggest cryptocurrency busts in British history.

Ponzi Scheme, Bitcoin, and a Lavish UK Lifestyle
Between 2014 and 2017, Qian lured tens of thousands of investors in China, particularly targeting middle-aged savers and retirees, with the promise of unusually high investment returns. Disguising herself under the name Yadi Zhang, she was often referred to as the “goddess of wealth”, promoting the scam through public events while falsely claiming ties to government agencies.
Once Chinese authorities began investigating, Qian escaped to the UK in 2018 using fake documents. There, she converted her victims’ money into Bitcoin and attempted to clean the funds by purchasing high-end properties, including a £23 million London mansion.
UK police tracked Qian through surveillance operations and financial records. A breakthrough came when authorities followed her Malaysian accomplice, Seng Hok Ling, which led to Qian’s arrest in April 2024. During coordinated raids, police recovered cash, gold, and crypto assets worth £11 million, in addition to the massive Bitcoin haul.
Record-Breaking Crypto Seizure
The British authorities’ seizure of more than 61,000 Bitcoins, now valued at over $6 billion, became a central pillar of the case. It is regarded as the largest cryptocurrency seizure ever made in the UK, and one of the most valuable globally.
Qian pleaded guilty on September 29 at Southwark Crown Court to charges of acquiring and possessing criminal property. Her sentencing will occur over a two-day hearing, where she could face up to 14 years in prison under the UK’s Proceeds of Crime Act.
Her associate Jian Wen, already convicted in relation to the scheme, was previously sentenced to six years and eight months in jail. Seng Hok Ling has also pleaded guilty and is awaiting sentencing.
Devastated Victims Still Await Justice
More than 1,300 victims have come forward in civil proceedings, according to sources close to the case. Many lost life savings, pensions, or money meant for their children’s education. One Chinese couple, who attended a promotional event in 2016, lost hundreds of thousands of dollars and have since suffered irreparable damage to their family life, with their daughter cutting ties completely.
Lawyers involved say the case may be the largest ever involving an individual and not a corporation. A compensation plan is still being hashed out in London’s High Court to determine how victims might recover part of their lost investments.
CoinLaw’s Takeaway
In my experience covering crypto fraud, this case is a rare mix of scale, sophistication, and emotional devastation. What struck me most was not just the $6 billion figure, but how deeply personal the losses were for ordinary people who trusted someone promising financial security. I found it especially heartbreaking that retirees and families were misled by staged events and flashy promises. This should be a wake-up call for global authorities to tighten crypto oversight and for investors to be extra cautious with too-good-to-be-true offers. While justice is being served in court, the road to full restitution for victims will be long and uncertain.
