Control and Simplicity

Bitcoin is a simple and complete way that allows you to send and receive money without going through a bank or any other organization.
Security

The Bitcoin network is secured in a decentralized way by hundreds of miners. Its
source code is freely available, its functioning is therefore transparent.
Lower fees

Unlike existing alternatives (Paypal, Blue Cards, Bank transfers ..) Bitcoin network usage costs are low.
2017 update: Bitcoin fees are now fairly high and solutions are being developed to address this issue.Limited supply

Unlike the Dollar or Euro, the total number of Bitcoin in circulation is limited. This therefore prevents anyone from reduce the value of your currency by creating more (Inflation).
