Several cryptocurrency projects reported to WuBlockchain that they incurred substantial intermediary fees for listing their tokens on South Korea's largest exchanges, Upbit and Bithumb. The fees were reported to be approximately $10 million for Upbit and $2 million for Bithumb. In response to these allegations, Upbit issued a statement strongly denying the claims and characterized them as unfounded. The exchange invited anyone with evidence to report it. This controversy comes amid a broader discussion about listing practices in the cryptocurrency market, with some comparing Upbit's listing process to that of Binance. Additionally, KuCoin announced the listing of a new token, $BUBB, with trading set to begin on March 21, 2025, at 13:00 UTC.
