ArsTechnica just posted a story about Dave Carlson who says he's 'slightly below' his target of 7-10 percent of the world's mining power! He's running more than 1.4 million BitFury mining chips out of Washington state. The company has less than 10 people and Carlson owns about 5,000 bitcoins. He didn't even get his first rigs up and running until July 2013. Quite an accomplishment!
