South Korea Fines Bithumb 210M Won For Unauthorized Overseas Data Transfers

South Korea’s Personal Information Protection Commission has reportedly fined crypto exchange Bithumb 210 million won, or roughly $136,000, over violations tied to overseas user-data transfers. The repaired source batch cites Korea Herald reporting for the enforcement details and classifies the article as secondary-supported.

According to the batch, the case involved Bithumb sharing member numbers and USDT order details with BingX under consent intended for Stellar-related activity. It also says the exchange transmitted user names and wallet addresses to 13 foreign exchanges during asset transfers without obtaining separate approvals.

Because the exact PIPC notice URL was not included, the article should attribute the enforcement details to Korea Herald reporting and avoid presenting the article as a direct translation of an official notice.

The case matters because crypto exchanges handle unusually sensitive data. User identity, wallet addresses, order details and transfer records can reveal financial behaviour in ways that ordinary account data may not. When that information crosses borders, consent and disclosure rules become especially important.

Other South Korean exchanges will likely review their own data-transfer consent processes after the case. Any platform sharing order, wallet or identity data with foreign partners may need clearer disclosures and stronger recordkeeping.

The corrective order may matter more than the fine itself if it leads to broader operational changes at Bithumb. Privacy enforcement can force exchanges to update internal systems, not just pay penalties.

For Bitcoinist readers, the story is another sign that crypto regulation is widening beyond trading rules into the full operational stack of exchange businesses.

This article treats the figures and claims as source-attributed because the repaired batch classifies the candidate as secondary-supported. That means market-data, on-chain, media, or dynamically served reporting sources are used for part of the story, rather than a single static corporate or regulatory filing.
