South Korean Regulators Examine Bithumb's Bitcoin Error

Key Points:

Bithumb credited users with ~620,000 BTC mistakenly.
Regulators investigate potential market manipulation.
Financial loss of ~$9 million for Bithumb.

South Korean regulators have not made formal statements requiring the return of mistakenly issued Bithumb tokens. Investigations by the FSC and KFIU are ongoing, focusing on internal control failures and potential market manipulation during the Bithumb incident.

South Korean regulators are examining Bithumb’s erroneous Bitcoin credits during a promotional event from February 5-7, 2026, affecting cryptocurrency markets significantly.

Investigation Details

Bithumb staff mistakenly credited ~620,000 BTC during a deposit-trade promotion. This resulted in a temporary localized crash of BTC prices by 15-17%. Regulators are currently investigating the anomaly and potential manipulation. The Financial Services Commission (FSC) has suspended similar promotions and is looking into Bithumb’s internal controls.

The Korea Financial Intelligence Unit (KFIU) has initiated a probe on anti-money laundering practices. The immediate impact included a flash crash of BTC prices on Bithumb, falling 15-17% below global averages. Bithumb has reportedly reimbursed the affected users with Korean Won. Financial implications include Bithumb compensating for unrecovered BTC through its funds, with a loss estimated around ~$9 million. The error exposes risks of promotion-related trading and may influence future exchange regulations.

The “unjust enrichment” lawsuits Bithumb considers could set precedents for how credited errors are managed in crypto.

Regulatory Insights

Regulatory insights suggest that increased compliance checks could become standard, impacting exchange operations. Historical cases show that such issues require thorough investigations to determine lapses and address vulnerabilities. Exchanges may need to refine their systems to prevent similar occurrences.

South Korea’s rigorous emphasis on financial security and consistency in crypto operations may further tighten exchange oversight. The error’s financial burden could influence smaller firms’ strategic planning, emphasizing strict operational protocols.
