Dammit, I want one. Has anyone run ROI through a calculator based on ~$.10kWH?
I can go do it, but if someone has it off the top of their head...
At $.10/Kwh, I don't think you break-even before the halving in 2016. Unless of course Bimtain delivers
YOUR S7 for say $1500, or maybe they limit deployment of the S7 (i.e. sales), or maybe Spondoolies delays deployment of the SP50 until well into 2016, or maybe BTC price goes up to $300 next week and stays there (or above).
Just keeping adding enough parts to an optimistic scenario, and I am sure you can make it work out!

Break even is for me right now 256 days out including power costs. Think that puts me right AT halving. But no one knows what the difficulty increase will be once these things saturate the market and the extra KnC and Bitfury facilities they are building come online. Ultimately through tax breaks, loss taking, and other accounting gimmicks (all legal) is the way I'm going to be lowing my ROI quite a bit. Then we got the final sale of the machine itself. I have 3 S5 units right now. I'd be happy to dump them for half my purchase price to 33% of purchase price (in 2016) as long as the other party pays shipping. Then get another S7.
