shit... over 100% increase? and for at least 6 months?
Probably not but it won't help. Looking at those estimates just as a ballpark view you see that most of gross revenue will come in the next 2 months and difficulty is almost certainly going to quadruple by the end of the year. The growth MAY (or may not) slow down after that but by then you are looking at 0.01 BTC per month so even lets say it slows down to only 50% growth per month so you make a couple more months at 0.01 BTC and then a couple more at 0.005 BTC and then a couple more at 0.0025 BTC. In the long run it doesn't change the gross revenue much.
I would point out that $18 per GH is just insanely overpriced. It is like saying is a Prius a bad deal at $2,800,00 ea? Won't I show a profit from the reduced gas consumption?
Miners paying <$5 per GH are unsure if they will show a profit (and they may or may not there are a lot of unknowns). $18/GH is just taking your money and lighting it on fire hoping it will produce a profit.
