According to my minergain account with a single S9, based on the prices that the block was found, I made $114 which currently is worth $97 since I am HODL.  My power is .124 per kw, so just under $140 to power it for the month.  So yes, a bit of a loss.  The crazy part is that I just bought and installed 2 more S9's for way less then my first S9 since there are so many coupons going around from bm and they delivered it in a little over a week.  I have bought btc straight out and had more of a loss on that so far.  So it really is whether you believe in the long term opportunity of BTC and whether you can pay for your power and HODL.
