Wu said that according to Newsis, Lee Bok-hyun, director of the Financial Supervisory Service of South Korea, said at the National Assembly Political Affairs Committee that the regulatory authorities are investigating the abnormal cryptocurrency transactions on the Bithumb exchange. The investigation focuses on the abnormal rise and fall of cryptocurrencies such as Avail in the Korean market, especially the phenomenon of inconsistency with other global markets. After Avail went online at 263 won on July 23, it soared to 3,500 won within 15 minutes, but fell to 296 won less than a day later, raising suspicions of price manipulation.
