Bitcoin is a currency that is fundamentally changing the way people think about money. It is completely digital and not controlled by any government or business entity. Bitcoin issuance is scheduled, predictable, and finite, so there is no risk of a large increase in bitcoins reducing the value of yours. Addtionally, bitcoin transactions are verified by the largest computer network in the world to ensure your transactions occur quickly and accurately.
Advantages of bitcoin
Bitcoin was designed to address the failures of existing currency systems:
- Instant transfers – transactions can be viewed on the network instantly and occur 24 hours a day, 7 days a week. Compare this with bank transfers that can take 2-3 days and are constrained to business operating hours.
- Worldwide trade – transfers can occur from anywhere connected to the internet, and are not constrained by geographic or political boundaries.
- Low or zero fees – most bitcoin transactions can be done for no fees, or for just a few cents, regardless of transaction size.

- Sell – Like any other currency, people sell products and perform services in exchange for bitcoin. During the month of March 2013, sales of products for bitcoins surpassed $10 million USD in value.
