If your electricity price is over $0.2, you will not be profitable when the difficulty double from current level.
who knows ? If the price goes up ? Even Eth mining is becoming less profitable, yet the best coin to mine now... Am I wrong ?
theres an x11 coin thats a bit more profitable i think (not by much, its about $1.25-$1.50/R9,270x/day)
That is quite good for the R9 270x as the card's price is cheaper than the 280x or the 380x. It will ROI.
if you focus on ROI, you can mine Eth only. With a 7950, in 2 months, one can mine 20 Eth. If ETH price is $10, $200 from a card in 2 months.
