[Alpha Biz= Paul Lee] Seoul, South Korea — September 3, 2025 —
Bithumb, one of South Korea’s leading cryptocurrency exchanges, experienced a trading service outage of over 100 minutes beginning late on September 2. Users reported being unable to execute trades as early as 11:30 p.m., roughly 15 minutes before the company officially announced a system check.



The unexpected suspension left investors frustrated, particularly as global markets awaited key U.S. economic data releases this week. Online communities quickly filled with complaints such as, “My order didn’t go through right after I placed it,” and “I can’t sleep without knowing the price.”



Bithumb issued a notice at 11:45 p.m. citing “temporary order processing delays” and completed system checks by 1:09 a.m. on September 3. The exchange also cautioned that pending orders might be canceled if post-maintenance price discrepancies occurred compared with global exchanges.



Criticism mounted over the exchange’s delayed communication. Users noted that while transactions froze around 11:30 p.m., the official notice was not posted until 15 minutes later. This led many customers to troubleshoot their own devices before realizing it was a platform-wide issue.



Bithumb previously suffered a similar outage in November 2017, when a sudden spike in traffic caused by sharp cryptocurrency price swings forced a 90-minute trading suspension.
