from where you get that from my post? i've used an online calculator, and any calculator right now is telling me that 1 s7 = $200 per month, and it was higher before much higher i know there is the diff but you need to begin from when the s7 was launched, with double the earning
That 200$ per month is... for how many months?
For what I see, it's only for the first few months.
You have your ROI, but then, difficulty (usually) increases and increases, and after very few months your income becomes nearly nothing.
You can't really say "200$ per month" in Bitcoin mining, because that changes FAST because of difficulty adjustments.
