Bitcoin is a revolution that took the world by storm, people talk about it in every day of their life. The knowledge behind this revolution is a top notch. Kudos to the brain behind it.
The way it is structured is second to none. The technology and the technical know how is another thing that baffles me. Selling the coin to someone you have not met and the person paying money to someone he too has not met in trust is another dimension of trust. In all Bitcoin is built on trust though ,there are those that will want to cheat.
