At $0.02 per KW, you are profiting on average $320.00 per month for each S7
You have to recoup your initial "investment" (purchase price of hardware + psu) before you see any profit. Even with 2 cent power (which is rare in and of itself) you won't see profit for over a year. That's why I mention ROI even at low power rates. New hardware purchased at retail price just doesn't make any sense right now.
Most people however can buy the new stuff, mine for 6 months, sell and then they are already at 50%+ Profits. I still don't see how you won't see profits for a year.
At a monthly profit of $320 that's 5.5months until ROI. Even at higher average Diff, it will be 7-8 months at the worst.
Also let's not forget Bitcoin prices. Right now they are low. When (and I mean WHEN) they head back up. profitability inreases by a ton.
Gotta pay to play.
