The Hanoi Police Department in Vietnam has prevented 300 potential victims from investing in a meticulously designed cryptocurrency scam that has defrauded approximately 10 billion Vietnamese dong (1.17 million USD) from around 100 businesses and 400 individuals. It is reported that the Hanoi police have arrested individuals associated with Million Smiles, a company that orchestrated an illegal and fraudulent cryptocurrency investment scheme targeting Vietnamese citizens, promoting its internal cryptocurrency QFS (Quantum Financial System), and using deceptive advertisements to link it with ancestral treasures and spiritual claims.
