Bithumb Origins Traced to Gaming Marketplace Roots in Korea Crypto History

Bithumb’s origins are often harder to trace than those of other early South Korean crypto exchanges, largely because key early figures kept a low public profile and left relatively few records. A new installment of TokenPost’s ongoing “Korean Cryptocurrency Pioneers” series argues that to understand how Bithumb took shape, readers need to step back before the exchange era—toward the formative experiences of Lee Jung-hoon and the online gaming item marketplace that helped build the mindset and operating DNA later associated with Bithumb.

The series, produced by TokenPost in collaboration with Professor Kim Hyung-joong, documents the behind-the-scenes history of Korea’s crypto industry through weekly episodes published on Tuesdays. While the project spans multiple companies and personalities, this episode focuses on a recurring theme in Korea’s early digital economy: how high-frequency online commerce, platform fees, and trust problems in peer-to-peer transactions became an informal training ground for entrepreneurs who would later enter cryptocurrency.

According to the report, Bithumb’s early leadership differed from peers such as Korbit, Coinplug, and Coinone, whose founders tended to be more visible and publicly active during the industry’s formative years. Bithumb’s early CEO Kim Dae-sik and then-vice president Lee Jung-a are described as central to the exchange’s initial launch, but not as figures who sought media attention. Kim later stepped back from management following a 2017 server outage crisis, a moment that remains one of the more widely remembered incidents in Bithumb’s early operational history.

To explain the exchange’s quieter beginnings, TokenPost traces the story to Lee Jung-hoon’s early life as an avid gamer—an obsession that reportedly became so consuming that he was expelled from the mechanical engineering department at Jeonbuk National University. The episode describes Lee as someone who effectively “lived” at PC cafés during the peak era of Korean online games, playing titles such as Lineage, StarCraft, and Fortress.

The narrative pinpoints a turning point in late 2001, when Lee—looking for money to buy a Christmas gift for his girlfriend—sold a game item he had accumulated. The item reportedly fetched about 500,000 won (roughly a few hundred U.S. dollars at the time), and the experience reframed virtual goods from entertainment to monetizable assets. In the series’ telling, it was an early realization that digital scarcity and player demand could translate into real cashflow—an insight that would later feel familiar to anyone watching cryptocurrencies turn online communities into markets.

But the report emphasizes that the more Lee traded, the more frustrated he became with the economics of the platform model. Each transaction incurred fees of roughly 5%, a cut that increasingly felt like an unnecessary leak of value. That irritation, TokenPost suggests, pushed Lee toward a founder’s impulse: if the ‘toll’ is too high, build the road yourself.

Lee’s response was to pursue a new marketplace intended to compete with ItemBay, an early online platform founded in 2001 that facilitated the trading of game items. The result was ItemMania, framed in the episode as a direct attempt to redesign how digital asset transactions could be conducted and monetized. While the excerpted installment stops short of detailing the full path from gaming commerce to crypto infrastructure, it positions ItemMania as a crucial proving ground—where operational thinking around ‘platform fees’, user behavior, and the mechanics of trust began to take shape.

The episode’s broader implication is that Korea’s crypto industry did not emerge in isolation. It grew out of earlier online markets that normalized the buying and selling of intangible goods, long before tokens became mainstream. In that context, Bithumb’s later rise can be read not only as a product of the 2017 bull market, but also as an extension of Korea’s long-running experimentation with digital trade—where the lessons of game-item markets helped seed the next wave of financial platforms.
