According to the Jinan Daily, in 2023, police in Dezhou, Shandong discovered an underground money transfer network utilizing virtual currency for fund transfers while investigating a telecommunications fraud case. Through meticulous tracking of fund flows and analysis of account circulation patterns, economic investigation officer Li Weiwei identified a new money laundering model combining "traditional underground money transfer + virtual currency." Police ultimately identified 12 major criminal suspects, over 100 fund accounts, and 6 virtual currency wallet addresses, froze assets involved in the case, and successfully solved Dezhou's first underground money transfer case involving virtual currency.
