Bitcoin’s Gains May Fuel Central Bank Concerns: Chart of the Day

An increase in the value of bitcoin, the world’s largest online currency, may fuel concerns that virtual money could undermine the role of central banks.

The CHART OF THE DAY shows that bitcoin has more than doubled in the past 12 months, strengthening to $16.37 from $5.88, according to data from Mt. Gox, the world’s largest bitcoin exchange. The money, issued by a decentralized network of computers, has recovered after falling to $2.14 in November 2011 from a high of $29.58 five months earlier.
