The U.S. Marshals Service held 22 cryptocurrencies valued at about $919 million last December, according to spokeswoman Shaunteh Kelly. In February the U.S. made its largest financial seizure ever: about $3.6 billion in Bitcoin stolen during a 2016 hack of the Bitfinex currency exchange. And cryptocurrencies made up almost all—93%—of the assets confiscated by the Internal Revenue Service’s Criminal Investigation Division in the fiscal year that ended Sept. 30.
