币界网报道:Coinbase revealed it assisted the U.S. Secret Service in seizing $225 million in stolen crypto linked to a 2023 human trafficking and "pig butchering" romance scam. The exchange traced illicit funds on-chain and identified victims for restitution. The seizure, involving frozen USDT from self-custodial wallets, marks the largest in Secret Service history. Tether, which blocked $225 million in December 2023, stated it has now frozen $2.7 billion tied to criminal activity. The Department of Justice acknowledged Tether's cooperation, while Coinbase detailed its multi-day transaction analysis to aid investigators. Victims may file claims through the FBI's Internet Crime Complaint Center.
