Financial traders have a new toy: Bitcoin, a digital currency variously dismissed as a Ponzi scheme or lauded as the greatest invention since the Internet.
Unlike conventional fiat money and other digital currencies, Bitcoin runs through a peer-to-peer network, independent of central control. Bitcoins are currently worth $4.88 each on online currency exchanges, where they can be bought and sold for about 15 world currencies.
Any where there is money to be made ... the banks are already there
