The Bitcoin

When the question, "Are bitcoins the currency of the future?" was asked, I was a little confused. What are these bitcoins? What's wrong with dollars bills? Bitcoins are basically a computerized form of currency. However, at the moment, the seem inconvient and pointless, because people are using the current form of currency much more frequently than bitcoins. They also seem to be unsafe at the time, because they are all computerized, and so a computer crash could cause many issues in the economy. For the time being, as well as the next several years, i believe that bitcoins will not be the currency commonly used. However, in the far future, with Improvents in technology and changes with how people shop, they may be more commonly used.
