Money is an invention that we made in order to be accepted as payment for goods and services that we have get. We created it 100.000 years ago, and since then we have never stopped evolving it. At the beginning they were small pieces of gold with some kind of inscription that made them different from the rest, nowadays most of the money we use is a piece of paper with some pictures and holograms on it. Money has evolved a lot, but the way we trade/exchange it almost remained the same. This is starting to change with the arrival of Internet, which will enable to by-pass one of the oldest institutions in the world: Banks. What started as a new way to share files and music with friends over the net is just about to become a new way of exchange one of the most important assets in our lives: Money.
