Bithumb Fined for Unauthorized Sharing of User Data Overseas

BlockBeats News, June 25th, the South Korean regulatory agency has ordered the cryptocurrency exchange Bithumb to pay a fine of 210 million Korean won (approximately $13,600) for sharing user personal information with overseas platforms without user consent.

According to the announcement released by the Personal Information Protection Commission (PIPC) of South Korea on Thursday, the user information leakage occurred between September and November 2025. At that time, Bithumb transferred user information to overseas platforms when sharing its USDT market order book data.

PIPC also pointed out that when assisting users in transferring assets to 13 overseas exchanges, Bithumb failed to obtain complete and sufficient user consent when sharing personal information such as user names, wallet addresses, and dates of birth. In addition to imposing a fine for the above two violations, PIPC has also instructed Bithumb to rectify its related processes and management system for transferring user information overseas.
