Foresight News reported that according to Wu Blockchain, multiple projects revealed that in order to list on the South Korean cryptocurrency exchanges Upbit and Bithumb, they paid high intermediary fees, which were approximately $10 million and $2 million respectively. These intermediaries are related to Upbit's shareholders and market makers.

Wu Blockchain further stated that some projects also said they provided intermediary fees ranging from 3% to 5% of the total token amount, and were ultimately successfully listed on Upbit. However, not all projects paid intermediary fees. Among the 7 projects contacted by Wu Blockchain, 3 of them stated that they did not pay any intermediary fees.
