Bithumb Exchange Faces $44B ’Ghost Bitcoin’ Crisis as FSS Mandates User Repayment
South Korea's Financial Supervisory Service (FSS) has intervened in the Bithumb exchange's catastrophic administrative error, where 620,000 BTC (~$44 billion) were mistakenly distributed to users instead of the intended 2,000 KRW (~$1.40) promotional rewards. Governor Lee Chan-jin clarified that recipients face legal obligations to return the funds under unjust enrichment laws, though users who confirmed transactions with Bithumb may avoid penalties.
The incident—triggered by a typographical error during a promotional event—has exposed systemic vulnerabilities in crypto exchange ledger systems. Market observers note the irony of such a flaw occurring in South Korea, home to the world's most stringent crypto compliance frameworks.
Bithumb's attempted recovery of 13 billion KRW (~$9.5 million) in misallocated BTC remains ongoing, with the exchange likely facing existential regulatory scrutiny. The FSS has signaled this case will inform its 2026 policy agenda for digital asset oversight.
