According to CoinMeta, as reported by chosun and biz, South Korea's two major cryptocurrency exchanges, Upbit and Bithumb, have listed the same crypto assets on the same day for 35 trading days this year, raising doubts about the independence of coin listing reviews on both platforms. For example, on November 10th, Upbit listed Hyperliquid at 14:00 Beijing time, while Bithumb opened its Korean won market for trading at 15:30, with only a 90-minute interval between the two. The report suggests that such frequent synchronization of coin listings may be related to preventing user and liquidity loss, maintaining market share, and generating transaction fee revenue. Industry insiders are calling for South Korea's financial regulatory authorities to strengthen supervision over the exchange's compliance with coin listing reviews and self-regulatory obligations.
