Step 1: Why Bitcoin?
First off Bitcoin is decentralized, there is no overarching controller of the currency, the information about the transactions are held by everyone in the network. Next bitcoin transactions are recorded anonymously. This means that people can see that bitcoins are being traded, but the recorded transaction does not have a name attached. Lastly bitcoin is a worldwide currency and has a constant rate between countries. This allows people regardless of borders to trade funds easily.
If you think you could benefit from bitcoins or just want to geek out on the next cool thing, setting up bitcoin is an easy process.
