According to Yonhap News Agency, South Korea has dismantled multiple fraud gangs that disguise themselves as investment experts and lure victims into investing in cryptocurrency with high returns as bait. It is reported that these groups operated in a residential office complex in Incheon from June 2023 to April 2025, stealing a total of 730 million Korean won (approximately 522000 US dollars). These fraudulent activities are carried out by a tightly structured team, including a mastermind, team leaders responsible for training and communication, and telephone customer service representatives who contact the victims. They operate fraud communities through phone calls and social media to obtain funds.
