The US Department of Justice has seized a significant sum of bitcoin worth approximately $15 billion stolen from a Cambodian businessman, Chen Zhi, in 2020. The seizure follows a four-year period during which the stolen funds remained dormant in an inactive hacker wallet. This unusual inactivity suggests the involvement of a state-level hacking organization. In June 2024, the stolen bitcoins were moved to a new wallet and have remained untouched since then. On October 14, 2025, criminal charges were filed against Chen Zhi, and US authorities seized a further 127,000 of the original stolen bitcoin from him and his business, Prince Group. This seizure is likely linked to a hacking incident that saw nearly all assets of the LuBian mining pool, which was responsible for the initial theft, lose over 90% of its total value after the attack in 2020.
