Bitcoin holds as Bithumb’s $40B error prompts FSS review

Key Takeaways:

• Internal system error credited huge BTC balances to customer accounts.
• Mis-credit sparked abnormal trading and acute price dislocations on Bithumb.
• Major South Korean probe targets internal controls, audit trails, promotional interfaces.

Bithumb’s accidental Bitcoin payment incident escalated after an internal system error credited large BTC balances to customer accounts. The mis-credit triggered abnormal trading activity and acute price dislocations on the venue.

The episode unfolded within hours, as users discovered unexpected balances and tried to trade or withdraw them. It reflected an internal ledger error rather than on-chain Bitcoin transfers, underscoring operational risk in exchange accounting.

As reported by AOL, the blunder briefly turned ordinary users into nine-figure Bitcoin holders. That scale amplified liquidity mismatches and forced unwinds in some accounts.

BitcoinEthereumNews.com reported that the mistake has already prompted a major market probe in South Korea. Regulatory scrutiny is focusing on internal controls, audit trails, and how promotional systems interface with live balances.

According to ChainCatcher, South Korea’s framework requires crypto exchanges to route deposits and withdrawals through real-name bank accounts issued by partner banks, making these contracts essential for fiat access. The outlet added that KB Kookmin Bank, Bithumb’s partner, is asking the exchange to strengthen internal audits ahead of renewal, while K Bank and Kakao Bank are closely monitoring counterparties before extending agreements. This more cautious stance reflects heightened reputational and operational risk assessments after the incident.

Banks’ renewal decisions are likely to weigh an exchange’s system design, segregation of promotional credits from tradable balances, and incident response. “Bithumb has since recovered 99.7% of the 620,000 Bitcoins mistakenly distributed, worth about $44 billion,” said Reuters. Recovery reduces immediate balance-sheet exposure but does not resolve control and governance gaps raised by the error. According to Yonhap, top financial authorities signaled tougher scrutiny, placing the Financial Supervisory Service (FSS) at the center of follow-up oversight and contract reviews.

At the time of this writing, Bitcoin (BTC) was around 66,908, with very high short-term volatility of about 12.19% and momentum readings near neutral. These figures are background context only and do not imply any view on future prices.
