The investigation found that the exchange shared Tether’s USDt order book data with BingX between September and November 2025, despite only having user consent to share data with Stellar.PIPC acknowledged that sharing certain information may be necessary to comply with anti-money-laundering requirements for crypto transfers. However, it said exchanges must still follow legal procedures governing overseas data transfers and obtain the required user consent.The fine adds to Bithumb’s growing regulatory challenges. The exchange was previously hit with a six-month business suspension by South Korea’s financial watchdog over alleged violations of the Financial Information Act, though a court later overturned the sanction. Police also raided Bithumb’s offices this month as part of an investigation into alleged nepotism involving lawmaker Kim Byung-gi.English translation of the PIPC’s announcement imposing a fine on Bithumb.

The exchange will then buy back shares held by MIXI and Ceres, leaving SBI with 100% indirect ownership. SBI expects the transaction to close around October, subject to regulatory clearance.The acquisition would expand SBI’s regulated crypto exchange footprint and customer base, giving it another potential distribution channel for the stablecoins, tokenized assets and onchain financial products.Bitbank’s daily trading volume has hovered below $50 million for most of the last four months, CoinGecko data showed. Volume is dominated by the BTC/JPY pair (39.5%), followed by XRP/JPY and ETH/JPY (both at 19.7%).SBI said combining Bitbank with SBI VC Trade would give the group about 1.1 trillion yen in assets under custody and roughly 2.92 million crypto accounts, based on figures from the end of April. The company said the combined business would rank first among Japanese crypto exchanges by assets under custody and among the largest by account numbers.Bitbank trading volume has hovered below $50 million for most of the last four months.
