Russian police have arrested over 300 individuals involved in a large-scale cryptocurrency scam that defrauded thousands of victims. The operation targeted a criminal group running fake investment platforms promising high returns on digital assets. Authorities seized significant evidence, including cash, luxury vehicles, and computer equipment, during coordinated raids across multiple locations. The scheme, active for several years, is believed to have caused substantial financial losses, with initial estimates exceeding millions of dollars. Russian officials emphasized the increasing sophistication of crypto-related crimes and the importance of international cooperation in combating such frauds. Investigations are ongoing to identify additional accomplices.
