Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH
At this point when I bought the S7 I did it mostly to lower my power costs over the SP20/S5, but I knew it probably would never ROI. Mining has pretty much been for "suckers" past the GPU days.
ROI depends on how you look at it. They are paid for out of the total farm BTC income. I haven't paid with fiat (~8k$) since April 2014. I've bought scads of miners, 2x TV's, 3x PC's, 5x UPS's, and more with the BTC earned and still have a sizeable BTC kitty left over even after ordering 2 more s7's a few days ago.
So, just how is mining after the GPU days now for "suckers"?
