Why Bitcoin Prices are at a Five-Month High

The currency's value has risen despite a spate of negative headlines. Earlier this month the feds arrested the alleged mastermind of the Bitcoin-based narcotics marketplace Silk Road. In July, federal regulators shuttered an alleged Bitcoin Ponzi scheme. And the leading Bitcoin-based exchange, the Japan-based Mt. Gox, has had a series of problems, including a U.S. government crackdown and an acrimonious legal dispute with a former business partner.
