Bitcoins are decentralized, purely digital virtual coins exchanged directly between two parties online with no middle man. Unlike modern fiat money, bitcoin, which has often been called “cash for the Internet,” is not controlled or backed by any bank or central government authority, like the Federal Reserve, for example.
Bitcoins are pieces of computer code — mathematical algorithms, actually — that represent monetary units. There are currently approximately 11 million Bitcoins in existence. In all, only about 21 million bitcoin will ever be generated through the year 2140. Unlike credit card transactions, bitcoin transactions, which take place internationally every day, are irreversible; they can only be refunded by the person receiving the funds.
