A Costly Mistake Shakes South Korea’s Crypto Market
South Korea’s cryptocurrency industry was rocked after Bithumb accidentally distributed bitcoin worth more than $40 billion to hundreds of customers, triggering panic inside the exchange and renewed scrutiny from regulators. What was intended as a small promotional reward spiraled into one of the largest operational blunders ever recorded in digital asset markets.
The error occurred during a routine customer promotion in early February, when Bithumb planned to distribute modest rewards of 2,000 won—roughly $1.40—to selected users. Instead, an internal processing mistake caused the system to credit recipients with 2,000 bitcoins each, briefly turning ordinary account holders into multi-millionaires.
How the Bitcoin Glitch Unfolded
According to Bithumb, the incident was not the result of hacking or a cybersecurity breach, but rather a human input error compounded by insufficient internal safeguards. Roughly 695 customers were affected, with 249 opening their promotional “reward boxes” before the exchange detected the anomaly.
Within minutes, trading activity surged as some recipients sold or transferred the mistakenly issued assets. Bithumb halted withdrawals and trading for affected accounts within 35 minutes, managing to reverse or freeze approximately 99.7% of the distributed bitcoin. However, a small portion—estimated at around $9 million—was already irretrievable, having been withdrawn or converted into other cryptocurrencies.
The event caused temporary price distortions on Bithumb’s platform, highlighting how internal accounting errors can ripple across exchange order books even without external interference.
Regulatory Fallout and Legal Uncertainty
South Korea’s Financial Supervisory Service moved quickly to assess the incident, calling emergency meetings to determine whether further investigation was warranted. Officials emphasized that while no hacking occurred, the scale of the mistake exposed structural weaknesses in exchange oversight and transaction verification systems.
Legal experts remain divided on whether customers who sold the mistakenly credited bitcoin could face criminal liability. A 2021 South Korean Supreme Court ruling determined that cryptocurrencies do not always qualify as “property” under criminal law, complicating potential prosecutions. Civil courts, however, may still compel recipients to return the value of assets received in error.
Bithumb has reportedly begun one-on-one negotiations with customers who cashed out during the brief window, seeking voluntary repayment in order to avoid prolonged legal disputes and reputational damage.

Impact on Customer Trust and Market Confidence
The incident comes at a sensitive time for South Korea’s crypto industry, which has worked for years to restore credibility after previous exchange collapses and regulatory crackdowns. While Bithumb emphasized that customer funds were never at risk, the episode raised uncomfortable questions about operational resilience at major trading venues.
Trust is especially critical in crypto markets, where users rely on centralized exchanges to maintain accurate internal ledgers despite handling decentralized assets like Bitcoin. Even brief lapses can undermine confidence, particularly among retail traders who already view exchanges as opaque intermediaries.
To mitigate damage, Bithumb announced compensation measures including fee waivers and goodwill payments to users active during the incident. The company also pledged to overhaul its internal controls and deploy AI-driven anomaly detection systems to flag abnormal transactions in real time.
Broader Implications for Crypto Regulation
Beyond Bithumb, the episode has reignited debate in Seoul over whether existing safeguards are sufficient for exchanges handling trillions of won in daily volume. Regulators are increasingly focused not only on cybersecurity threats, but also on internal governance, employee access controls, and system redundancies.
Lawmakers have signaled that the incident may accelerate proposals requiring stricter separation between promotional systems and live asset ledgers, as well as mandatory multi-layer approval for any transaction exceeding preset thresholds.
Globally, the case adds to a growing list of costly operational failures across traditional finance and digital assets alike, underscoring how automation without adequate checks can amplify human error at scale.
A Defining Test for Bithumb’s Future
For Bithumb, South Korea’s second-largest crypto exchange, the coming months will be critical. While the company avoided catastrophic losses, the reputational impact could linger as competitors emphasize reliability and regulatory alignment.
Whether the exchange emerges stronger or weakened will depend on how convincingly it can demonstrate that this incident was truly an isolated failure—and not a symptom of deeper systemic fragility in crypto infrastructure.
