Hi,
I'm new on bitcoin, but I want to do something.
Right now I know that mining is not profitable and everyone here advice to buy BTC.
I want to dig some btc just for fun. My PC is strong enough (2x HD6990 in crossfire) but I don't want be kill by my electricity bills.
I want to buy some hardware and I was thinking about BitFury USB (=~ 2.5GHs and 2.5W) so it will not kill me
Is it good idea? And where in EU I could get it cheep?
