The US government is auctioning off some of the Bitcoins it seized from the illegal Silk Road operations. This isn’t the first time the US government is selling off its shiny Bitcoins in an auction. The first batch of Bitcoins that the US government sold at auction was around 30 000 Bitcoins. That auction, which was held in June, lured in 45 bids. A great number seeing how you needed a lot of cash to get in on the bidding.
