Yum also followed the electronic trail of the bitcoins that were moved from Silk Road servers to the laptop used by Ulbricht. He found that between September 2012 and August 2013, a total of 700,253 bitcoins were moved to the laptop, in about 3,700 separate transactions. The value of the bitcoins, at the times of their individual transactions, totalled about $13.4 million, he testified.
In addition to the bitcoins that came from Silk Road, the laptop also received 89,000 bitcoins from other sources, which the government did not identify.
Ulbricht was charged with narcotics conspiracy, engaging in a continuing criminal enterprise, conspiracy to commit computer hacking and money laundering. The narcotics and criminal enterprise charges carry maximum penalties of life in prison. Ulbricht has pled not guilty to all charges.
U.S. District Judge Katherine Forrest is overseeing the case.
