Bitcoin hit a high of $1,073 on Tokyo- based exchange Mt. Gox, the best-known operator of a bitcoin digital marketplace, compared with just below $900 the previous day.
Bitcoin is not backed by physical assets and is not run by any person or group. Its value depends on people's confidence in the currency. It has been gaining acceptance by the general public and investment community but has yet to become an accepted form of payment on the websites of major retailers such as Amazon.com.
