South Korea Slaps Coinone with $3.5M Fine for AML Failures

Regulatory Crackdown Hits Coinone

South Korean financial authorities have issued a $3.5 million fine against Coinone, one of the nation's largest cryptocurrency exchanges. The penalty follows an investigation into the firm's anti-money laundering (AML) protocols, which regulators found failed to meet established legal standards. Beyond the financial penalty, the exchange faces service suspensions as the government intensifies its crypto market analysis and oversight of digital asset service providers.

Regulators identified gaps in customer verification processes and transaction monitoring. These deficiencies allowed users to operate without proper identification, violating the strict guidelines enforced by the Financial Intelligence Unit (FIU). The exchange, which remains a competitor to leaders like Upbit and Bithumb, must now overhaul its compliance infrastructure to satisfy the state's requirements.

Failure of Compliance Controls

The probe into Coinone’s operations revealed specific areas of concern that led to the multi-million dollar fine. Investigators pointed to the following systemic failures:

• Inadequate Customer Due Diligence: The exchange failed to verify the identities of several users who opened accounts on the platform.
• Missing Transaction Monitoring: Suspicious activity reports were not filed in accordance with the law, creating blind spots for regulators.
• Operational Oversight: Internal controls were deemed insufficient to prevent prohibited financial activities.

This enforcement action aligns with a broader trend in the region. Regulators are increasingly scrutinizing how platforms handle Bitcoin (BTC) and Ethereum (ETH) to prevent money laundering and illicit capital flight.
