Bithumb Error Spurs Korea Crackdown After $44B Credit – Feb 2026

A Bithumb bitcoin error briefly credited users with roughly 620,000 BTC during a promotional “Random Box” event on Feb. 6, 2026, triggering an exchange-only price dislocation and an emergency regulatory response in South Korea. Authorities said the incident exposed structural weaknesses in exchange ledger systems and sent inspectors to probe why basic safeguards failed.

Context

Bithumb is one of South Korea’s biggest crypto exchanges and a major venue for BTC-KRW trading, so operational errors can ripple through local liquidity fast. The incident landed as Seoul pushes “phase two” crypto rules that target market integrity, exchange governance, and stronger internal controls.

Regulators framed the problem as more than a bad promo payout. They argued that if virtual assets are to be treated like legitimate financial assets, exchanges must prove their electronic systems cannot generate tradable “phantom” balances through simple operational mistakes.

Details

Reporting said the error occurred during a “Random Box” promotion when the reward unit was entered incorrectly, resulting in bitcoin-denominated credits instead of small won-denominated rewards. Multiple outlets reported that roughly 620,000 BTC was wrongly credited across 695 users, while 249 users actually opened the reward boxes.

Bithumb identified the error in about 20 minutes and froze the affected accounts within about 35 minutes, according to reports. The exchange later said it recovered 99.7% of the assets, implying about 0.3% was sold before recovery.

FSS Governor Lee Chan-jin tied the episode directly to systemic operational risk: “If problems in virtual asset information systems such as phantom coins are not blocked, structural risks can arise at any time.” – Lee Chan-jin, Governor, Financial Supervisory Service (FSS), Feb. 9, 2026.

Impact

The most visible market effect was local and short-lived: BTC on Bithumb briefly dropped about 17% to 81.1 million KRW (about $55,400) even as global prices stayed above $66,000, according to reporting that compared Bithumb’s prints with broader markets. The gap suggested venue-specific selling pressure rather than a global repricing of bitcoin.

Regulators focused on what the price move implied about controls. If an internal ledger can display massive balances that do not reflect verified holdings, it can enable trades and withdrawals that overwhelm risk checks and customer protection processes.

The case also added friction to Seoul’s broader push to connect crypto with traditional finance, including ongoing discussions around spot Bitcoin ETFs.

Next Steps

The Financial Supervisory Service dispatched an inspection team to Bithumb and said it would escalate to deeper on-site examination if it finds legal violations, according to regulator statements carried by local press. Investigators are examining why a transaction of that magnitude did not require multiple layers of approval and what safeguards failed inside the exchange’s virtual-asset electronic systems.

Lee also addressed the legal obligations tied to mistaken credits: “If [the bitcoin] was sold and converted to cash, those users incur an obligation to return it in kind.” – Lee Chan-jin, Governor, Financial Supervisory Service (FSS), Feb. 9, 2026.

On the company side, Bithumb set up a 100 billion KRW customer protection fund and announced compensation steps aimed at restoring trust after the incident, according to reports. Regulators, meanwhile, signaled tougher operational standards as part of the second-stage virtual-asset rule package now moving through the policy pipeline.
