A South Korean man has received a harsher sentence after appealing for a reduced penalty in a case involving cryptocurrency money laundering for a voice phishing ring. Initially sentenced to 2 years and 6 months in prison with a 4-year probation by a local court, the Suwon High Court revoked the probation and imposed a 4-year prison term. The court determined that the defendant played a "key role" in the operation, having identified himself as the "person in charge" and receiving daily operational reports from the group.
