According to ChainCatcher, according to Yonhap News Agency, South Korean prosecutors have conducted the first investigation into former congressman Kim Nam-guk (transliteration), which is aimed at possible illegal cryptocurrency transactions during Kim's tenure as a congressman.

Previously, it was reported that former congressman Kim Nam-guk held virtual currencies such as Wemix coin, Mabrex, and Bora worth up to 6 billion won (about 4.48 million US dollars), which aroused public suspicion about the source and use of his investment funds. He was also suspected of using undisclosed information obtained from the gaming industry to conduct improper transactions and make profits by purchasing coins at low prices.
