South Korea’s largest crypto exchange Upbit has listed Sophon (SOPH) as a trading-flagged asset and has suspended deposits. Upbit said that SOPH has several shortcomings in areas such as timely disclosure of major matters, transparency and reasonableness regarding changes to its circulating-supply plans, and related procedures for such changes, which may result in user losses. The review period is expected to run until the week of October 12 to 16; if the related issues are not adequately resolved, support for trading may ultimately be terminated.
