The U.S. Department of Justice (DOJ) said in a statement Tuesday that it had recovered billions of dollars worth of bitcoin stolen in a 2016 hack of Bitfinex, the cryptocurrency exchange affiliated with the world’s biggest stablecoin, Tether.

In the largest financial seizure ever, law enforcement has seized over $3.6 billion in bitcoin out of the total $4.5 billion drained in the hack as it arrested a couple in Manhattan Tuesday morning for an alleged conspiracy to launder the stolen coins. The two individuals are scheduled to appear in federal court in the afternoon.
