Anyway - our 3 x S2's are generating around 0.07 btc per day on BTC Guild so after hosting/energy costs will never ROI
Total Waste of Money, will never do business with those guys again...
What about, for example, 1000 $ for 1 BTC? Or any greater exchange ratio? Bitcoin must to grow up...
if that is the case then you are better off buying BTC directly on coinbase (or some exchange site). that way instead of just breaking even or making a little if it goes to $1000 you have doubled your investment. check my sig for another cheap miner option
