Manhattan federal prosecutors boasted Friday that they have seized $48 million from convicted Silk Road mastermind Ross Ulbricht.

Ulbricht, serving a life sentence for his role in running the illegal online drug marketplace, gave up his right to the money recently when he “withdrew his claim,” the feds said, citing an order from Judge Katherine Forrest.

Ulbricht had initially contested the feds’ right to the loot, which they scored after finding 144,336 bitcoins on his laptop computer.
