South Korea's second-largest cryptocurrency exchange, Bithumb, has found itself in a catastrophic predicament after accidentally awarding 620,000 bitcoins to qualifying customers during a promotional event. The mistake, which occurred last week, was attributed to an employee entering prize amounts in bitcoin rather than Korean won, resulting in approximately $42 billion in erroneous credits being sent to the recipients.
The error has left Bithumb scrambling to recover over $9 million of the cryptocurrency, with around 13 billion won ($40 billion) still unrecovered after some customers sold or withdrew their funds before the issue was detected. The exchange has since corrected most of the mistaken credits but acknowledges that about 86 customers took advantage of the situation and sold approximately 1,788 bitcoins in just 35 minutes.
The incident has raised concerns over "structural problems" in how cryptocurrency exchanges operate internal ledger systems, according to Lee Chan-jin, governor of South Korea's Financial Supervisory Service. Bitcoin prices have since risen, putting any customers required to return cryptocurrency at risk of losses.
Separately, legal experts are divided on whether recipients who sold their bitcoin could face criminal prosecution under Korean law, which does not currently recognize cryptocurrency as a form of property. Bithumb has taken a cautious approach, engaging in "one-on-one persuasion" talks with roughly 80 customers who cashed out and seeking to avoid civil lawsuits.
The exchange's response to the incident includes a redesign of its asset payment process and enhancement of internal control systems. In an apology, Bithumb acknowledged that the error was not due to external hacking or security breaches but emphasized that it is committed to preventing such incidents in the future. The Financial Supervisory Service has escalated its investigation, while South Korea's parliament has scheduled an emergency hearing on February 11 to question both the exchange and financial authorities.
