Taiwanese police recently arrested two executives of what has been described as one of the region’s largest cryptocurrency exchanges, ACE Exchange. The arrests followed an investigation which concluded that the duo had helped trick 100 individuals into buying “worthless virtual currencies.” According to a Liberty Times Net report, Lin Nan, one of the executives, used the promise of quick riches to lure unsuspecting people into investing. Lin Nan’s alleged accomplice, Pan Nan, reportedly listed the fake virtual currencies on ACE to boost their credibility. The duo was able to perpetrate the scam for three years before law enforcement agencies caught up.
