According to Foresight News, a man in his twenties has been sentenced to one year in prison in South Korea for committing cryptocurrency investment fraud. The individual was found guilty of promising investors a 10% monthly return and the ability to withdraw their principal at any time, under the pretense of investing in virtual currencies. However, he was unable to fulfill these promises due to significant personal debt. Additionally, he failed to perform his duties as a social service worker without a valid reason, contributing to his sentencing.
