I don't think you understood the question. I have a farm with 79 Terrahashs of Bitmain and Avalon equipment. I wanted to
know if anyone, off the top of their head, has done the calculations for the ROI on ONLY the S4 based on rumored price
and the crap performance of the coins value over the last month (and of course taking into consideration the difficulty swings).
There are too many conflicting stories out there from people that don't have a clue about much else than sitting at home with
their three S1's just "burn'n up" the pool they're in and thinking they have all the answers. (I haven't even met people with
more than I have with all the answers!)
