Among major cryptocurrency exchanges in South Korea, Upbit ranked first in customer satisfaction during the first half of 2025 (January–June), followed by Bithumb and Coinone in second and third place, respectively.
According to market research firm Data&Research, the number of posts containing the keywords “customer” and “satisfaction” across 12 online channels (news, blogs, communities, SNS, etc.) amounted to approximately 29,241 for Upbit, 16,352 for Bithumb, and 2,671 for Coinone. Compared to the same period last year, the total volume increased by over 50%, attributed largely to rising investor confidence amid the recent surge in Bitcoin prices.
Upbit’s dominance was driven by factors such as its over 70% market share, broad range of listed tokens, responsive services, and user-friendly interface. Enhanced security features—including OTP systems and cold wallet storage—also played a major role in positive sentiment, especially after past security incidents.
Bithumb drew attention with news of its upcoming corporate spin-off scheduled for August 15 and IPO plans, as well as a Jeju flight promotion in partnership with KB Pay. A company spokesperson noted that “efforts to specialize business operations and prepare for IPO are helping to regain user trust.”
Coinone saw increased mentions following the expansion of its integration with KakaoBank, allowing users to view their crypto balances directly within the banking app. Many users praised this feature, citing greater convenience in asset management.
Meanwhile, Korbit (1,251 mentions) and GOPAX (417 mentions) trailed behind the top three but continue to carve out space with their respective strategies. Data&Research remarked, “The recent recovery in investor sentiment is driving overall satisfaction levels higher,” and added, “Further service innovations will likely increase visibility and engagement for each exchange.”
