With the massive growth in mining difficulty (10,455,720,138 at the time of writing, and rising fast), a 1 or 2 GH/s USB stick simply can’t compete with a dedicated ASIC mining rig running in the TH/s range.If they’re profitable at all after the retail price and the cost of electricity, it’s usually a matter of pennies per day.While this can be a fun, low-cost way for hobbyists to play around with bitcoin mining, the era of commercially produced USB miners appears to be drawing to a close.If HexFury has its way, however, low-cost USB miners might just be making a comeback.raspberry pi bitcoin minerPowered by six current-generation BitFury ASIC chips, the HexFury runs at a respectable 11 GH/s.raspberry pi bitcoin minerTechCrunch’s John Biggs got his hands on one, and reported that it consistently hit about 12 GH/s.“It looks like an overgrown thumb drive with exposed innards, which should give owners of inquisitive cats pause.”The HexFury is theoretically hashing fast enough to generate about 0.018 BTC per month at current difficulty.bitcoin json api list

That’s about $10 at current prices, meaning you’d need a little over a year and a half (at stable difficulty) to break even on the $200 miner.While that’s a hard sell to an experienced bitcoin miner, it might be just the thing for a hobbyist.As Biggs noted:Home mining, at this point, is more about the experience of mining than any real money making.… As these things catch up with higher-powered units, it’s only a matter of time before we can all make a few BTC a month with something the size of a stick of gum.bitcoin news hard forkThe US Marshals Service is in charge of auctioning off almost 30,000 bitcoins that the federal government seized from Silk Road servers last year, and it had planned to do so in an anonymous auction this month.armory bitcoin unlimitedBut that anonymity was compromised on Wednesday when the US Marshals Service accidentally revealed the names of several potential bidders by sending around an auction FAQ to a group of e-mail addresses that it placed in the CC field rather than in the BCC field.bitcoin wallet two factor

As CoinDesk first reported, Lynzey Donahue, a US Marshals spokeswoman, said that “The message was not intended for any particular group of people, but for anyone who had e-mailed a question to the general mailbox to ask about the auction.Only recipient e-mail addresses were disclosed.” Donahue added that “The USMS apologizes for this mistake which was in no way intentional.” Although not everyone on the list is a potential bidder in the upcoming auction, TechCrunch shows the subject of the e-mail as “Bitcoin Auction Frequently Asked Questions,” so it's safe to assume that at least some of the names on the list are likely interested in placing a bid.bitcoin paper wallet passwordThe tens of thousands of bitcoins up for auction are currently worth around $18 million.bitcoin farming speedThe US Marshals hopes to auction off the bitcoins in several blocks.bitcoin old man rapper
