South Korea delivers first prison sentence under crypto user protection act
South Korea is tightening its grip on the cryptocurrency sector, with courts handing down the first prison sentence under an investor protection law enacted last year. The ruling comes just as financial authorities signal a comprehensive overhaul of digital asset governance, ranging from ownership caps to the tokenization of real-world assets.
The Seoul Southern District Court sentenced the head of a crypto management firm to three years in prison for manipulating virtual asset prices and amassing roughly 7 billion won in illegal profits, according to Yonhap News Agency. The court also imposed a fine of 500 million won ($340,000) and ordered the forfeiture of approximately 846 million won ($580,000).

First sentence under 2024 protection law
This marks the first conviction under the new investor protection law, which took effect in July 2024. It was also the first case fast-tracked directly from the Financial Supervisory Service (FSC) to prosecutors under the new legal framework.
The conviction coincides with a broader regulatory debate involving Financial Services Commission (FSC) Chairman Lee Eog-weon. According to MoneyToday, in testimony before the National Assembly’s National Policy Committee on Feb. 5, Lee outlined an agenda covering anti-money laundering (AML) enforcement, stablecoin regulation, and digital innovation. However, he cautioned lawmakers against enacting blunt, one-size-fits-all rules that could stifle competition.
Ownership cap rules trigger debate
Lee pushed back against a proposal to cap major shareholder stakes at 15%, pointing out that the exchange market is already a monopoly where smaller players hold less than 3% combined. He warned lawmakers that forcing firms with negligible market share to dilute ownership would effectively choke off investment. He argued that such restrictions would stifle innovation, advocating instead for a tiered regulatory approach that accounts for new entrants starting with no market share.
Lee also addressed a separate policy direction that would recognize bank-led consortia—in which banks hold more than 50% plus one share—as eligible stablecoin issuers. He said the approach was not intended to favor any particular corner of the financial industry.
On the enforcement side, the commission announced plans to strengthen its response to cross-border crime and money laundering involving digital assets, as reported by Digital Asset. A key measure under consideration is the expansion of the travel rule, which requires exchanges to share sender and recipient information for transactions. The rule currently applies to transfers of 1 million won ($680) or more, and regulators want to extend it to smaller transactions as well. The commission also pledged to support AI-driven transformation across the financial sector and to build a comprehensive regulatory framework for digital assets.
STOs near legalization
In a related development, South Korea has cleared a major legislative hurdle for the tokenization of real-world assets (RWAs). Amendments to the Capital Markets Act and the Electronic Securities Act passed the National Assembly last month, roughly three years after financial authorities first issued guidelines on security token offerings (STOs), according to another Digital Asset report. The legislation allows securities to be digitized on blockchain-based distributed ledgers and creates a new class of issuer account management institutions, enabling qualified companies to issue and manage security tokens directly. The bill now requires only Cabinet approval and official promulgation before it takes effect.
