Odaily Planet Daily News: The police department in Hanoi, 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 about 100 businesses and 400 individuals. It is reported that the Hanoi police have arrested individuals associated with Million Smiles Company, which orchestrated an illegal and fraudulent cryptocurrency investment scheme targeting Vietnamese citizens, promoting its internal cryptocurrency QFS (Quantum Financial System). In addition to promising unrealistic returns, the company also falsely claimed that owning QFS would allow individuals and businesses to access the financial ecosystem and enjoy benefits such as unsecured or interest-free financing.
