Chen Zhi, a Cambodian businessman accused of running a transnational scam network, was extradited to China in January. However, his lawyer has filed a motion in a New York federal court to overturn the US government's seizure of approximately 127,271 bitcoins. The lawyer argues that the charges are "clearly erroneous" and questions the connection between the bitcoins and any fraudulent or money laundering activities. Previously, the US Department of Justice accused Chen of operating a global scam and gambling network, leading to the freezing of his substantial assets.
