Virtual currency bitcoin is starting to get its act together. A startup funded with $106 million from the New York Stock Exchange as well as banks and venture capital firms, is set to launch the first licensed US bitcoin exchange. Coinbase reckons it'll add increased security to traders as well as monitor real-time pricing of the world's foremost cryptocurrency. If you've forgotten, unlike normal currencies, bitcoin is traded virtually and isn't backed by a central government: reasons why the currency often fluctuates severely. The collapse of Mt. Gox last year stung investors, both professional and otherwise, for a total sum of around half a billion dollars. As the WSJ notes, the value of a bitcoin is currently around $240: it was stood at $1,200 per 'coin.
