A list of potential buyers for almost 30,000 bitcoins confiscated from the now-defunct Silk Road black marketplace has been leaked via email by the US Marshals Service (USMS), the US government agency confirmed.

In a statement to CoinDesk, Lynzey Donahue, a US Marshals spokeswoman, indicated that the emailer had intended to send all the recipients an attached informational document and to blind copy all those it intended to contact. The US Marshals service is the federal agency that has been charged with carrying out the auction of the bitcoins, originally seized by the FBI.
