South Korea To Drop Massive Fines on Its Top Crypto Exchanges — Bithumb, Coinone, and Korbit First in Line

Key Takeaways

• South Korea’s financial watchdog is preparing a new round of sanctions on major crypto exchanges for KYC/AML violations.

• Bithumb, Coinone, Korbit, and GOPAX are expected to face penalties following months of on-site inspections.

• Regulators will issue sanctions in the order inspections were completed, with Dunamu (Upbit’s operator) already hit with heavy fines.

South Korea’s crypto industry is bracing for another wave of enforcement as the country’s financial watchdog prepares to sanction several major exchanges for anti-money-laundering failures.

According to local reports, the Financial Intelligence Unit (FIU) has completed a year-long series of on-site inspections across the country’s top crypto trading platforms.

Now, the regulator is moving into the penalty phase, one that industry observers say could mirror the heavy sanctions recently imposed on Upbit’s operator, Dunamu.

Bithumb, Coinone, Korbit First in Line

After finishing on-site inspections of Upbit, Bithumb, Coinone, Korbit, and GOPAX, the FIU is now conducting legal reviews and preparing its sanctions committee.

Officials are following a straightforward “first-in, first-out” rule: the earlier an exchange was inspected, the sooner its penalties will be finalized.

That puts Korbit, GOPAX, Bithumb, and Coinone next in line, likely in that order.

The inspections focused on compliance with South Korea’s Special Financial Transactions Act, particularly whether exchanges properly enforced Know-Your-Customer (KYC) verification and reported suspicious transactions.

An industry official interviewed by local media said that because the FIU reviewed each exchange under the same legal framework, the severity of sanctions “is unlikely to differ meaningfully” from those levied against Dunamu.

In February, the FIU issued a disciplinary warning to Dunamu’s CEO and suspended Upbit’s onboarding of new customers for three months.

It followed up with a fine of 35.2 billion KRW ($26 million) for KYC failures and reporting lapses.

A Country With One of the Toughest Crypto Rulebooks

South Korea’s crypto legislation is widely recognized as one of the strictest in the world.

Regulators have long maintained that fast-growing digital-asset markets require oversight on par with traditional finance—if not stricter.

That posture grew out of two major moments: the ICO boom of 2017, when retail speculation exploded, and the 2022 market contagion triggered by global exchange failures.

Both pushed lawmakers toward a more conservative, risk-averse stance.

In recent years, South Korea has tightened rules across the board:

• Mandatory KYC and AML reporting for every crypto operator

• Severe penalties for non-compliance, including fines up to five times the illicit gains and potential jail time

• Ongoing monitoring of exchanges through surprise inspections

• A gradual expansion of approved crypto investment products under tightly controlled conditions

The FIU’s latest enforcement sweep is part of a broader effort to clean up the domestic market before the country opens the door to more traditional financial products tied to digital assets.

What Happens Next?

With sanctions against Bithumb, Coinone, Korbit, and GOPAX still in progress, the FIU’s enforcement cycle is expected to continue into early 2026.

Industry analysts say the coming penalties could reshape the competitive landscape, especially if some platforms face temporary suspensions or lose parts of their operating licenses.

Others argue the crackdown could have the opposite effect, boosting institutional confidence by demonstrating that South Korea intends to keep its crypto sector tightly regulated.

Either way, the next round of sanctions will send a clear message: South Korea expects its exchanges to adhere to the same standards as its banks, and regulators are willing to take aggressive action when they fall short.
