Bithumb's recent mishap involving an erroneous Bitcoin distribution has led partner banks to reassess their contractual relationships. The incident, described as a "unit error," resulted in BTC being mistakenly sent to event winners. In response, Coinone's partner KakaoBank and Upbit's partner K-Bank are scrutinizing the renewal of their real-name account contracts. Additionally, KB Kookmin Bank, another Bithumb partner, has demanded enhanced internal controls before considering contract renewal next month, citing concerns over reputational risks.
