In a dramatic escalation of its regulatory battle, South Korean cryptocurrency exchange giant Bithumb has filed an administrative lawsuit against the nation's Financial Intelligence Unit (FIU), challenging severe sanctions that include a six-month partial business suspension and a 36.8 billion won fine (approximately $27.5 million). The lawsuit, filed with the Seoul Administrative Court on March 23 through the prestigious law firm Bae, Kim & Lee, represents one of the most significant confrontations between a crypto platform and financial regulators in South Korea's history.
Simultaneously, Bithumb is moving forward with plans to reappoint its CEO, Lee Jae-won, for another two-year term despite the ongoing regulatory turmoil. The proposal will be presented at the company's March 31 shareholders' meeting, and if approved, Lee—whose current term expires this month—will continue leading the country's second-largest crypto exchange.
The regulatory penalties stem from alleged violations of the Act on Reporting and Using Specified Financial Transaction Information, legislation designed to combat money laundering and ensure financial transparency. The FIU, operating under the Financial Services Commission (FSC), imposed the sanctions after identifying deficiencies in Bithumb's compliance systems. The penalties also included a formal reprimand warning for CEO Lee Jae-won and a suspension for the firm's reporting officer.
Bithumb has strategically requested a stay of execution from the court, which if granted, would pause the scheduled suspension set to begin on March 27 until the court reaches a final verdict. This move highlights the exchange's urgent need to maintain business continuity during what could be a protracted legal process.
The regulatory challenges come amid additional operational controversies. Authorities are reviewing Bithumb's order book sharing arrangement with an overseas platform flagged as an unregistered operator. Furthermore, a probe by the Financial Supervisory Service into a high-profile system glitch on February 6—where users were mistakenly credited with Bitcoin amounts far exceeding the exchange's actual holdings—is nearing completion, raising the possibility of further sanctions.
Despite these mounting challenges, Bithumb appears to be prioritizing leadership continuity over restructuring, signaling an effort to maintain stability as the exchange navigates regulatory uncertainty and works to renew its virtual asset service provider license. The outcome of this legal battle will have profound implications for market operations, investor protection, and the future of digital asset governance in one of the world's most active crypto economies.
