South Korean cryptocurrency exchange Bithumb mistakenly displayed a warning telling some customers that foreign members could not use its services on November 10, 2026, before confirming that the message resulted from a website update rather than an actual change to account access.
The exchange acknowledged the problem in a notice published at 17:54 Korea Standard Time (08:54 UTC), saying an incorrect message had temporarly appeared for some users visiting its website. Bithumb said the problem had been corrected and customers could use its services normally.
The company also explicitly denied any connection to external hacking attempts, addressing concerns that the unexpected warning might indicate a security incident.
Bithumb confirms incorrect warning during website update
The message displayed to affected customers stated that foreign members were unable to use the exchange, according to screenshots reported by Korean media. For users seeing it on a screen, that looked rather final.
Bithumb explained that the warning appeared during a service update and did not reflect customers’ actual ability to access the platform. Its announcement described the incident as an incorrect display of information rather than an intentional restriction on trading accounts.
The exchange confirmed that corrective measures had been completed by the time its notice was published. It did not disclose when the incorrect message first appeared, how many customers encountered it or the specific technical fault that caused the error.
Nor did Bithumb provide transaction data establishing whether any customers abandoned attempted logins or trading activity after encountering the warning. Its official account maintains that the underlying services were unaffected.
The words were there, but the restriction apparently wasn’t.
The scope of the occurence also remains unclear. Bithumb’s statement specifically referenced its website, without identifying particular account categories, geographic locations or application versions affected by the incorrect display.
South Korea’s account rules add context to the warning
The reference to foreign customers was particularly sensitive because South Korea has historically maintained strict identity-verification requirements for cryptocurrency exchange accounts.
In January 2018, the country’s Financial Services Commission introduced a real-name bank account policy for cryptocurrency trading. The measures required customers to use verified banking accounts linked to exchanges and, when introduced, prevented foreign nationals from opening new linked accounts for cryptocurrency deposits.
That historical regulatory framework helps explain why a message concerning foreign customers might resemble a genuine eligibility restriction. It does not establish that Bithumb introduced any new restriction on November 10 or that the original 2018 conditions describe every aspect of its current customer eligibility policies.
Bithumb’s correction made no announcement of revised identification requirements, account-eligibility rules or new restrictions affecting foreign customers. The exchange identified the warning itself as the problem.
Separate Bithumb restrictions were announced the same day
The website error occurred on a day when Bithumb had already announced a genuine restriction involving certain overseas cryptocurrency businesses.
Earlier on November 10, at 10:05 KST, the exchange prohibited deposits and withdrawals involving six Canadian money services businesses following U.S. sanctions connected to alleged Iran-related financial activity.
The restrictions involving six Canadian businesses covered specified overseas counterparties, including Darvish Exchange and Million Exchange. They did not amount to a general ban on foreign customers or a suspension of all international cryptocurrency transfers.
That was a seperate operational measure, and one Bithumb explicitly announced as a transaction restriction.
The exchange had also recently imposed a narrower cryptocurrency-transfer suspension following an interruption on the Injective blockchain. On November 9, Bithumb joined other Korean exchanges in suspending INJ deposits and withdrawals after the network stopped producing blocks during a reported upgrade-related test.
Those incidents involved identifiable restrictions on particular transfers. The November 10 website warning, by contrast, contained a statement about customer eligibility that Bithumb said was incorrect.
Bithumb has previously made asset-specific decisions after security-related developments, including its handling of BONK following a $20 million DAO attack. That earlier case involved trading-support and deposit decisions, rather than evidence of unauthorized access to Bithumb’s own systems.
There is no established technical connection between those earlier measures and the latest website display error.
For traders, the unresolved detail is the actual lenght of time the incorrect warning remained visibile and the number of users who encountered it. Bithumb has released neither figure, and its public explanation does not identify the software change responsible for the message.
The exchange has confirmed that the warning was corrected and denied any hacking connection. Its announcement closes the immediate access-message problem, but the technical explanation remains rather thin, and that is where the public account ends.
