South Korea tightens cryptocurrency withdrawal restrictions following Bithumb's system failure

A wake-up call about systemic weaknesses

On February 6, 2026, during a regular promotional event, Bithumb staff mistakenly entered the reward unit as “ Bitcoin ” instead of South Korean won. This resulted in a massive virtual balance appearing in user accounts on the internal ledger.

Within minutes, some recipients attempted to sell or withdraw funds, causing a sharp drop in Bitcoin's price on the platform (Bitcoin fell to a low of around $55,000 on Bithumb ). Bithumb acted quickly: they restricted trading and withdrawals for affected accounts within 15-35 minutes, recovered 99.7% of the faulty BTC, and covered the remaining shortfall with company funds (including compensation for those who panic-sold).

No cyberattacks or security breaches occurred, but the event highlighted inadequate real-time monitoring and high-risk manual processes. Bithumb is now facing a six-month partial suspension of operations (March-September 2026) and a substantial fine for separate violations of anti-money laundering and customer verification.

The FSC's subsequent inspection of major exchanges (including its partnership with the DAXA Digital Asset Exchange Alliance) revealed that while all platforms generally held sufficient assets, reconciliation processes varied considerably and manual transaction safeguards were often inadequate.

The shift to continuous monitoring

The new regulations fundamentally change how exchanges operate. Instead of periodic checks, platforms must now implement a continuous reconciliation system, verifying customer balances against actual holdings in as little as five minutes.

This is not just a technical upgrade. It represents a shift in management philosophy from detecting problems after they occur to preventing them in real time. In fact, exchanges are being pushed toward standards closer to those of traditional financial institutions, where reconciliation and risk monitoring are ongoing processes rather than batch operations.

Withdrawal control as a risk mitigation tool.

Along with asset verification, authorities are also tightening withdrawal procedures. South Korea has mandated a 24- to 72-hour delay for cryptocurrency withdrawals after deposits to prevent fraud and facilitate quick withdrawals.

The new legal framework builds on that by ensuring that any withdrawal request is backed by a verified balance in near real-time. This helps mitigate risk:

• Payment error

• Internal system deviations

• Exploiting accounting loopholes quickly

The focus is shifting from external threats, such as cyberattacks, to internal operational risks—a type of risk that the Bithumb incident has shown cannot be ignored.

Higher cost, higher trust

The immediate consequence could be higher operating costs for exchanges, as real-time monitoring systems require more advanced infrastructure and tighter internal controls.

But in return, confidence is boosted. For a market inherently affected by volatility and occasional operational failures, this move can improve investor confidence, attract institutional participation, and reduce the likelihood of serious missteps.

Our review

South Korea's response to the Bithumb incident exemplifies a proactive, technology-driven management philosophy: viewing operational errors as systemic risks and addressing vulnerabilities before they escalate. The 5-minute reconciliation rule, combined with stricter withdrawal safeguards, could serve as a model for other countries seeking to balance innovation and consumer protection.
