Upbit response; Upbit does not allow the involvement of external agencies to assist or intermediate trading support, and all procedures are conducted directly by Upbit employees. Therefore, if a specific company or individual demands intermediary fees while claiming to guarantee trading support from Upbit, please be advised that this is the act of illegal brokers unrelated to Upbit, and we ask for your special caution to prevent any damage from such actions. https://upbit.com/service_center/notice?id=4971
