Seoul police have dismantled a family crime syndicate involved in laundering money through an unregistered virtual asset exchange. The group, consisting of 19 members mostly related by family ties, operated in Seoul's Myeongdong district. They converted large sums of cash obtained from telecom fraud into Tether (USDT) and transferred it overseas. The estimated amount involved in the scheme reaches several hundred billion Korean won. During the investigation, authorities seized approximately 6 billion won in criminal assets, including 4.05 billion won in cash, 1.5 billion won in silver beads, and 500 million won in gold bars. The operation highlights ongoing efforts to combat illegal financial activities involving cryptocurrencies in South Korea.
