My brother told me about bit coins, basically it's a form of online currency so can be used to buy stuff with off the internet. But what intrigued me more was that you can "mine" these coins, technically for free after the hardware is bought (there is ways of doing it on a web page though). In short I was wondering whether anyone knew anything about them or wanted to find out more about them as well? I should also mention that many people go into mining pools to gain more coins quicker so that also could be a good idea?
