South Korea's Financial Information Analysis Unit (FIU) is investigating Bithumb's compliance with order book sharing regulations involving the Australian Stellar exchange. The probe, reported by Yonhap News Agency, focuses on whether Bithumb meets the necessary licensing, registration, and anti-money laundering requirements. Despite Bithumb's consultations with regulators, authorities have expressed concerns over the adequacy of its compliance procedures. The FIU has indicated it will take action if any breaches of the Specific Financial Information Act are identified.
