Know before you buy or hold : In the U.S.A, different states have adopted varying approaches to Bitcoins. Recently a U.S Magistrate in the state of New York ruled that Bitcoins are not money, while a contradictory stance was taken by a judge in Manhattan, who ruled that bitcoins are acceptable means of payment. The Internal Revenue Service in the United States, defines bitcoin as property rather than currency for tax purposes. The U.S. Treasury, by contrast, classifies bitcoin as a decentralised virtual currency.
