A California man, Ken Liem, is suing three Asian banks, claiming they failed to prevent a crypto scam that cost him nearly $1 million. The lawsuit, filed in a California district court, accuses Hong Kong's Fubon Bank Limited, Chong Hing Bank Limited, and Singapore's DBS Bank Limited of neglecting essential checks like Know Your Customer (KYC) and Anti-Money Laundering protocols. Liem's attorneys argue these oversights allowed fraudsters to open accounts and transfer his funds under false pretenses. The suit seeks $3 million in damages and highlights alleged violations of the US Bank Secrecy Act.
