South Korean politician Kim Byung-ki has denied allegations of lobbying against cryptocurrency exchange Upbit while his son interned at rival exchange Bithumb. A former aide accused Kim of orchestrating attacks on Upbit's operator, Dunamu, during National Assembly sessions. Kim has been vocal about Upbit's market dominance and regulatory challenges but insists there is no link between his actions and his son's internship at Bithumb. Bithumb has stated that its hiring practices are transparent, amid growing scrutiny of exchange operations due to political and market pressures. Despite Kim's denials, both opposition members and some of his allies are calling for his resignation, highlighting the political tensions surrounding the issue.
