Some 120,000 BTC was stolen in the 2016 hack, then worth around $60 million and representing nearly one-sixth of the total trading volume at the time. At today’s prices, the total amount of bitcoin stolen is valued at $4.5 billion, but the DOJ only seized about 94,000 BTC valued at $3.6 billion. The DOJ release alleges the two conspired to launder these proceeds and heavily implies, but does not claim, they were the original hacker(s).
