how'd you compute? reason i ask is did a simple online one put in a conservative 70-100 day roi (btc basis, not fiat), hopefully comes in just in time terraminers kill gh mining. thnx!
Looks good however it seems that even at this price you will never ROI let alone profit. Assuming a 28% increase in difficulty every block even after a year and a half you will not earn your money back since 1 GH/s will be nothing in a year.
