Here is an interesting report on the rise of digital currencies. Bitcoin, a decentralised, virtual currency, is gaining increasing interest from investors and entrepreneurs. The currency is not controlled by a government or a central bank and is traded on the internet.In this short news video, the FT's Maija Palmer reports from a Bitcoin conference on where the currency is heading including the use as a person to person medium of exchange.
