According to the Jinan Daily, in 2023, Dezhou police in Shandong Province, China discovered an underground money laundering network utilizing virtual currency for fund transfers while investigating a telecommunications fraud case. Through meticulous tracking of fund flows and analysis of account transfer patterns, female economic detective Li Weiwei identified a new money laundering model combining "traditional underground money houses + virtual currency." Police ultimately identified 12 primary 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 house case involving virtual currency.
