• Police in the U.K. seized over 1.7 billion pounds ($2.2 billion) worth of bitcoin related to the alleged fraud in a 2018 operation.
  • Wen accused of laundering the proceeds of the fraud, converting the bitcoin into cash and purchasing property, jewelery and other luxury items.
  • Wen admitted to being control of a bitcoin wallet on behalf of her boss but claimed that she was unaware where the contents had come from.

As a researcher with a background in digital forensics and cybercrime investigation, I’m deeply troubled by the case of Jian Wen and the $6 billion bitcoin fraud she was involved in. The scale of this crime is mind-boggling, and it’s a stark reminder of how quickly cryptocurrencies can be used to facilitate illicit activities.


A British-Chinese woman stands convicted for her role in laundering $6 billion worth of bitcoin as part of a major fraud scheme in China. According to the Financial Times, she was sentenced to serve a six year and eight month prison term on Friday.

Jian Wen, aged 42, was convicted in March for her role in laundering money for her previous employer.

In a significant 2018 investigation in the U.K., law enforcement agencies confiscated approximately 1.7 billion British pounds (equivalent to around $2.2 billion) believed to be linked to fraudulent activities involving bitcoin. The accused, identified as Wen, allegedly laundered this digital currency on behalf of Yadi Zhang, whose true name is revealed as Zhimin Qian.

According to the Financial Times, Zhimian is accused of swindling approximately 130,000 Chinese investors out of roughly $5 billion through an investment fraud. However, her legal representative maintains that she is completely not guilty.

Wen wasn’t implicated in the fraud itself, but rather in laundering the ill-gotten gains, exchanging bitcoins for cash, and buying property, jewelry, and other high-end possessions.

She refused to acknowledge the accusations towards her. Her legal representative, Mark Harries, QC (Queen’s Counsel), asserted that she had unwittingly become involved in a deceptive situation instead.

Wen confessed to managing a Bitcoin wallet for her employer, yet she expressed ignorance about the origin of its funds.

“I am certain that you weren’t just guessing but had solid evidence that the money you were handling derived from criminal activities. This crime was intricately planned and executed with great care.”
