- •The UK government weighs restitution versus state reserves after $6.7B Bitcoin seizure.
- •International cooperation traced the fraud, securing assets across borders after pursuit.
- •The case shows how early crypto markets enabled scams before stricter regulations emerged globally.
In London, prosecutors have confirmed the largest Bitcoin seizure in British history after Zhimin Qian, also known as Zhang Yadi, admitted guilt in a massive fraud case. At Southwark Crown Court, Qian pleaded guilty to starting a $6.7 billion scam that defrauded more than 128,000 Chinese investors between 2014 and 2017. Authorities seized 61,000 Bitcoins, now worth over $6.7 billion, alongside $11 million in cash and gold.
How the Multi-Billion Dollar Fraud Started
Investigators revealed that Qian lured investors with promises of nearly 300% returns, presenting the operation as a legitimate Bitcoin investment platform. Victims, mostly aged 50 to 75, believed they were entering a risk‑free opportunity.
Many reinvested their savings after seeing simulated returns and fabricated daily dividends. Between 2014 and 2017, Qian converted investor deposits into Bitcoin, taking advantage of the asset’s rising value during that period.
When Chinese authorities began investigations, she fled using false documents and resettled in the United Kingdom in 2017. Her attempt to launder the funds through luxury real estate in London and Dubai raised financial system alerts, leading to a seven‑year probe by the Metropolitan Police.
The investigation, according to Detective Sergeant Isabella Grotto, required cooperation with many countries and the review of several documents. The scale of the case made it one of the most complex fraud probes in UK law‑enforcement history.
Seized Assets and Legal Challenges
Police confirmed that 61,000 Bitcoins linked to Qian have been secured, effectively doubling the UK’s digital asset reserves. The Crown Prosecution Service (CPS) emphasized that this recovery was the largest virtual‑asset seizure ever conducted in Britain. Additional confiscated assets included gold bars and cash deposits.
Deputy Chief Crown Prosecutor Robin Weyell stated that the case showed how crypto provides organized crime with avenues to disguise illegal gains. He added that the UK 2023 Economic Crime and Corporate Transparency Act was important in authorizing the seizure.
However, the challenge now changes to determining how the assets will be distributed. Victims in China are seeking restitution, while the UK government is considering whether surplus funds should be retained for national reserves. According to court filings, some Chinese investors have already received partial compensation under local government schemes, but the majority are uncompensated.

Benchmark for Crypto Asset Management
The decision surrounding the seized Bitcoin has wider implications beyond restitution. Selling the assets at auction could provide billions for public services, yet holding them could establish the UK as one of the world’s largest state holders of Bitcoin.
Legal experts have said that this case is a turning point in asset management, testing how governments use volatile digital holdings. Restitution for 128,000 investors will likely take years, as claims must be verified across international borders and diplomatic agreements with China.
Meanwhile, law enforcement agencies stress that the seizure is a progress in tracing digital assets across jurisdictions. Cross‑border cooperation between UK and Chinese authorities was key in recovering funds and building the case against Qian and her accomplice, Hok Seng Ling, whose sentencing is scheduled for November 10, 2025.
The scale of this fraud indicates how early crypto markets enabled large‑scale scams with limited oversight. Authorities argue that the growing use of compliance tools and stricter regulatory frameworks may reduce such risks in future cases.
Meanwhile, the seizure of 61,000 Bitcoins from Zhimin Qian demonstrates how law enforcement and crypto‑asset management now work on a global scale. The case shows how regulators handle volatility, cross‑border enforcement, and the complexity of restitution for more than 128,000 victims. With billions at stake, the UK’s approach may set a lasting example for digital‑asset seizures worldwide.
