South Korea's Financial Supervisory Service (FSS) has initiated a formal investigation into cryptocurrency exchange Bithumb following an embarrassing glitch that resulted in the accidental distribution of bitcoin worth millions to hundreds of users. Sources familiar with the matter revealed that the incident occurred late last week when a software error during a routine maintenance window triggered unintended payouts, dispersing approximately 50 BTC—valued at over $3 million at current prices—to verified account holders.
The mishap unfolded amid Bithumb's efforts to upgrade its wallet infrastructure, a move intended to enhance transaction speeds and security. Instead, the update inadvertently activated a payout mechanism linked to a promotional event from months prior, leading to bitcoin credits appearing in users' balances without corresponding deposits or authorizations. Affected customers, numbering around 450, quickly noticed the windfall and began withdrawing funds, prompting Bithumb to issue an urgent reversal notice and freeze related transactions within hours.
Bithumb promptly acknowledged the error in a public statement on its platform and social channels, apologizing to users and assuring that no customer funds were at risk from the company's own reserves. The exchange recovered most of the distributed bitcoin through voluntary returns and account freezes, though sources indicate a small fraction—estimated at 2-3 BTC—remains unrecovered, complicating the resolution. Bithumb has offered compensatory incentives to compliant users while vowing to reimburse any permanent losses from its insurance pool.
The FSS probe, which began Monday, focuses on Bithumb's operational safeguards, compliance with anti-money laundering protocols, and the potential for systemic risks in the rapidly evolving crypto sector. Regulators are particularly scrutinizing whether the glitch exposed vulnerabilities that could be exploited by bad actors, echoing past scandals like the 2019 Coincheck hack in Japan. Interviews with exchange executives and system audits are underway, with preliminary findings expected within weeks.
This episode underscores the tightening regulatory gaze on South Korea's dominant crypto exchanges, which handle billions in daily volume under stringent local laws mandating real-name verification and capital reserves. Industry analysts warn that lapses like Bithumb's could accelerate calls for even stricter oversight, potentially dampening innovation while bolstering consumer protections. As the investigation unfolds, Bithumb's reputation hangs in the balance, with trading volumes already dipping 15% in the aftermath.
