Sirgoo Lee was instrumental in shaping Upbit, the cryptocurrency exchange that captured over 80% of South Korea's onshore trading volume and significantly influenced global crypto prices in 2025. His impact stemmed from a management style at parent company Dunamu that favored open communication and decentralized responsibility, contrasting with typical Korean corporate hierarchy. Under his leadership, Upbit prioritized user safety by implementing systems to recover misdirected deposits (over 94%), establishing an Investor Protection Center, and expanding security certifications, distinguishing it as the safest venue for risk-embracing South Korean retail traders. Even after his 2025 exit as CEO, Upbit continues to dominate the hyperactive retail market he defined.
