Jian Wen (transliteration) used to be an ordinary employee working in a British restaurant, but her life changed drastically after becoming an assistant to a wealthy Chinese-American. Jian Wen was convicted by a British court of participating in money laundering, and 61,000 Bitcoins worth approximately £3.4 billion were seized during the investigation. These funds are alleged to have come from the fraud group that defrauded nearly 130,000 Chinese investors between 2014 and 2017. For the 61,000 Bitcoins seized, the British Crown Prosecution Service has initiated civil recovery proceedings in the High Court. If no one else is entitled to the assets, half of the confiscated funds go to the British police and the other half to the Home Office.

This case involves the seizure, freezing, seizure and disposal of virtual currencies and faces many difficulties. Problems such as difficulty in determining ownership, lack of value assessment standards, lagging technical means, and difficulties in international coordination make case processing more complicated. It is now necessary and urgent for all parties to improve the relevant laws and regulations involving the "inspection, freezing and seizure" of virtual currencies as soon as possible, form a consensus on supervision and law enforcement, strengthen international cooperation, and adopt convergent measures to combat crimes such as the use of virtual assets for money laundering. .
