Duyun City, Guizhou Province, China explores the storage method of virtual currency involved in the case, freezes it and seizes it in a cold wallet for physical isolation According to BlockBeats, after China strictly banned virtual currency trading in 2021, the storage and disposal of virtual currencies involved in cases has become a thorny issue for public security in various regions. Recently, a reporter from China News Network accompanied the media interview team of the Ministry of Public Security's "Guarding Under the Sun" rule of law public security theme promotion activity to visit the property co management center in Duyun City, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province, to learn about the local public security's practice of preserving virtual currencies involved in the case. In the process of handling the case, the public security organ found that a suspect had changed the illegal gains involved in the case into virtual currency. During the seizure process, Duyun Public Security froze the virtual currency involved in the case, detained it in a cold wallet set up by the public security organs for physical isolation, and stored it in the Duyun City Joint Property Management Center, waiting for the court's judgment. The exploration of Duyun Public Security in Guizhou provides a "solution" for the preservation of virtual currencies involved in the case, and various regions are still searching for better solutions. It is reported that Duyun Public Security is closely monitoring the difficulties in the custody, transfer, and disposal of the involved property, actively exploring reforms in the management of the involved property, and promoting the construction of a cross departmental joint management center for the involved property. Since its completion and operation in November 2022, the center has received 24753 items involved in the case, more than 20.4955 million yuan in involved funds, and centralized custody of over 7000 case files.
