South Korea's Supreme Court has made a landmark decision: Bitcoin and other cryptocurrency assets held on exchange platforms are now explicitly subject to seizure under criminal law provisions. This ruling clarifies the legal status of exchange-held digital assets in the country, establishing that these holdings can be confiscated as part of criminal investigations or legal proceedings. The decision carries substantial implications for how crypto exchanges operate within South Korea's regulatory framework and affects users' understanding of asset protection and custody risk on centralized platforms.
