Bithumb's $44 Billion Bitcoin Blunder — February 2026 Incident Report

What Happened: $44 Billion in 'Ghost Bitcoin'

At 7:00 PM on February 6, 2026, South Korea's second-largest crypto exchange Bithumb accidentally distributed approximately 620,000 BTC — worth roughly $44 billion — to users in what is now being called the 'Ghost Coin' incident. Bithumb was running a promotional 'Random Box Event' intended to reward participants with KRW 2,000–50,000 (about $1.40–$35) in cash. However, when processing the batch payout, an employee mistakenly entered the payment unit as BTC instead of KRW.

As a result, around 240 out of 695 participants received a minimum of 2,000 BTC each (worth approximately $1.4 billion). The total amount disbursed was 13–14 times the BTC Bithumb actually held (175 company-owned + 42,619 customer-held) and roughly 3% of Bitcoin's total circulating supply.

Timeline of Events

• Feb 6, 19:00 — Unit input error during batch payout of Random Box event rewards

• Feb 6, 19:00–19:30 — Some recipients begin selling the erroneously received BTC; 1,788 BTC sold in total

• Feb 6, 19:30–19:45 — Bitcoin price on Bithumb crashes ~15%, from KRW 95M to KRW 81.1M (approx. $55,000)

• Feb 6, after 19:45 — 64 forced liquidations triggered on Bithumb's lending service

• Feb 6, evening — Bithumb issues public apology and begins clawback

• Feb 7 — Bithumb announces compensation plan; financial regulators dispatch emergency inspection team

• Feb 8 — Financial Services Commission convenes emergency meeting with Bithumb executives

• Feb 9 — Compensation payouts begin; FSS Governor calls it a "catastrophic situation"; 7-day zero-fee period starts

• Feb 10 — FSS upgrades on-site inspection to formal examination; report submitted to National Assembly

Parallels to Samsung Securities' 2018 Ghost Share Scandal

The incident draws direct structural parallels to the 2018 Samsung Securities ghost share scandal, earning it the 'Ghost Coin' label.

• Samsung Securities (2018): KRW 1,000 dividend mistyped as 1,000 shares → ~KRW 112 trillion in phantom stock → 16 employees sold shares → 8 convicted

• Bithumb (2026): KRW 2,000 reward mistyped as 2,000 BTC → ~KRW 60.5 trillion in phantom BTC → some users sold (1,788 BTC)

The core issue is identical: assets that did not exist were created in the system and were tradeable, exposing a fundamental failure in real-time asset reconciliation and internal controls.

Market Impact and Collateral Damage

• Bitcoin price crash: ~15% drop on Bithumb (to approx. $55,000 globally)

• 64 forced liquidations: Cascading margin calls on Bithumb's lending platform

• Secondary victims: Regular users unrelated to the event suffered losses from the flash crash

• Exchange credibility: The incident spotlighted structural vulnerabilities of centralized exchanges

Recovery and Compensation

Of the 620,000 BTC erroneously distributed, 618,212 BTC (99.7%) has been recovered. Of the 1,788 BTC that was sold, 93% has been recovered in KRW and crypto. Bithumb's compensation plan includes:

• KRW 20,000 for all users logged in during the incident

• Full price-difference refund + 10% bonus for users who sold at depressed prices between 19:30–19:45

• Full compensation for all forced-liquidation victims

• Zero trading fees for 7 days starting February 9

Regulatory Response and Legal Issues

The Financial Supervisory Service (FSS) has upgraded its on-site inspection to a formal examination and is conducting a full review of Bithumb's internal controls. FSS Governor Lee Chan-jin called the incident "catastrophic" and outlined priorities for Phase 2 digital asset legislation:

• Major shareholder stake limits (15–20% cap under review)

• Financial-institution-grade internal control requirements

• Mandatory periodic external reserve audits

• Strict liability provisions for exchange system failures

Legally, criminal prosecution of users who sold the phantom BTC is considered unlikely based on a 2021 Supreme Court precedent. However, the FSS Governor stated that "unjust enrichment claims are clearly applicable," making civil recovery lawsuits highly probable.

Key Takeaways

The Bithumb incident goes beyond a simple 'fat finger' error — it exposed the structural risk inherent in centralized crypto exchanges. Eight years after Samsung Securities' ghost share scandal, an identical type of failure occurred in the crypto space, confirming that the industry's internal controls lag far behind traditional finance. This event is expected to accelerate regulatory oversight of crypto exchanges to levels comparable to established financial institutions.
