Investment seminars targeting middle-aged and elderly individuals are reportedly being held near Seoul's Seolleung Station, promoting an unlisted cryptocurrency. Promoters claim that investing in a certain crypto settlement business will yield dividends in 'A Coin,' which they assert will be listed on a major exchange by July, with prices expected to rise by at least 100 times, potentially up to 120 times. However, investigations reveal that 'A Coin' is not listed on major crypto data platforms. Last year, illegal activities involving virtual assets in South Korea resulted in losses amounting to $32.4 million, affecting over 40,000 victims. Investment fraud and pyramid schemes were the most prevalent types of cases reported.
