BTC Price Chart

South Korean regulators are intensifying scrutiny of cryptocurrency exchanges following a massive error at Bithumb, where approximately $40-$44 billion worth of Bitcoin was mistakenly distributed to users during a promotional event. While Bithumb has recovered the majority of the funds, roughly $8.6 - $9.5 million remains unsettled, sparking a formal investigation by the Financial Supervisory Service (FSS). The error, stemming from a unit conversion mistake and internal control failures, involved crediting users with 'phantom' or 'ghost' Bitcoin. The FSS is focusing on 'gating' practices, infrastructure vulnerabilities, and discrepancies between held crypto and user balances. This incident is expected to lead to stricter regulations under the Digital Asset Basic Act, including enhanced oversight standards, potential caps on ownership stakes, and the deployment of AI surveillance systems to detect market manipulation. Lawmakers are criticizing Bithumb’s internal controls, and the event complicates the exchange’s IPO plans, potentially benefiting competitor Upbit. The investigation highlights broader concerns about the reliability of centralized exchanges and the security of virtual assets within South Korea’s financial system.
