Bithumb has refuted claims that it collaborated with South Korean lawmaker Kim Byung-ki to undermine its competitor Upbit. Reports from KBS, South Korea's largest broadcaster, suggest that a Bithumb employee provided Kim's aides with materials critical of Upbit's operator, Dunamu, during a parliamentary audit. Allegations include that Kim attacked Upbit in parliament after securing an internship for his son at Bithumb. Bithumb maintains that its hiring practices are transparent and fair, denying any wrongdoing. The controversy has led to police investigations and calls for Kim's resignation from the Democratic Party. Kim, who has faced multiple accusations of corruption, denies all allegations, while his representatives label the reports as "groundless."
