The feds have seized its largest stash ever of Bitcoin, originating from the notorious Silk Road underground marketplace. The site was known for the place to go to broker illegal drugs, murder-for-hire, child pornography and malware such as password stealers, keyloggers and remote access tools. In 2013 the FBI shuttered it, arresting founder Ross William Ulbricht (a.k.a. Dread Pirate Roberts) in a range of crimes including computer hacking, and was sentenced to a double life sentence plus 40 years.
