The Associated Press reports of a Bitcoin heist in Iceland where thieves stole some 600 computers used to "mine" bitcoin and other virtual currencies. "Some 11 people were arrested, including a security guard, in what Icelandic media have dubbed the 'Big Bitcoin Heist,'" reports the Associated Press. From the report: The powerful computers, which have not yet been found, are worth almost $2 million. But if the stolen equipment is used for its original purpose -- to create new bitcoins -- the thieves could turn a massive profit in an untraceable currency without ever selling the items. Three of four burglaries took place in December and a fourth took place in January, but authorities did not make the news public earlier in hopes of tracking down the thieves. Police tracking the stolen computers are monitoring electric consumption across the country in hopes the thieves will show their hand, according to an industry source who spoke on condition of anonymity because he is not allowed to speak to the media. Unusually high energy usage might reveal the whereabouts of the illegal bitcoin mine. Authorities this week called on local internet providers, electricians and storage space units to report any unusual requests for power.
