China has accused the United States of hacking and seizing about $15 billion worth of Bitcoin linked to alleged scam kingpin Chen Zhi, claiming the funds were stolen without legal transparency. Chinese officials say blockchain movements suggest state-level hacking and question how U.S. authorities accessed private keys. Washington has not directly responded to the hacking claim, though U.S. prosecutors describe the Bitcoin as part of a record seizure tied to global fraud and money-laundering operations allegedly run by Chen.
