A cryptocurrency exchange CEO, identified as Mr. Lee, has been sentenced to four years in prison for attempting to leak military secrets to North Korea in exchange for Bitcoin. This marks his second conviction on these charges. Mr. Lee was indicted for violating the National Security Law after receiving approximately 700 million KRW (Korean Won) worth of virtual currency from an individual believed to be a North Korean operative. He then attempted to contact an active-duty officer to obtain and leak sensitive military information. According to Newsis, Division 4-1 of the Seoul High Court upheld the original sentence of four years. This case highlights the increasing concerns surrounding the use of cryptocurrency for illicit activities and the potential for national security breaches. The incident underscores the need for stricter regulations and vigilance within the cryptocurrency industry to prevent future incidents of this nature. ```
