According to Yonhap News Agency, South Korean prosecutors have launched their first investigation into former lawmaker Kim Nam-kook for possible illegal cryptocurrency transactions during his tenure as a lawmaker. Previously, it was reported that former lawmaker Kim Nanguo held virtual currencies worth up to 6 billion won (about 4.48 million US dollars) such as Wemix coin, Mabrex, Bora, etc., which aroused public suspicion about the source of his investment funds and the use of funds. He is also suspected of using undisclosed information obtained from the game industry to conduct improper transactions and make profits by buying coins at low prices.
