If BitCoin becomes really big we will need BitCoin satellites around the world to secure the network.
The technology of sending up satellites are getting cheaper and easier over time so I think this project is possible within a few years.
Looks like some people are working on projects like this already

The scheme was outlined at the Chaos Communication Congress in Berlin.
The project's organisers said the Hackerspace Global Grid will also involve developing a grid of ground stations to track and communicate with the satellites.
Longer term they hope to help put an amateur astronaut on the moon.
