Yes, but let's dust off the MagikSmoke 8 ball and look at the next few months:

Great analysis and summary of GPU outlook overall. This should be stickied for all those still asking "will GPU mining still be profitable?"
I'd like to get your opinion though, does this mean to you that the best time to sell GPUs would be today? I'm asking because i'm curious if we can still ride out our GPUs for 1 or 2 more months before the shit hits the fan. I'm pretty happy with ROI and all the coins i already have for long-term holding.
I sold off my 1070's. Sold off my RX 480s. I reduced my 1080 Ti's but keeping some, and keeping my Vega's for now. I do think 1080 Ti's are not going to go to $0 any time soon but I do keep a watch on eBay. If you've gotten your purchase price back out of them, not as big an issue.
Never had an ASIC miner until this year, and boy has that been a turn off. I ordered one of the Senseless modded FPGAs. Happy to share with the group how that goes once I get it.
In the meantime, I've got to dig out a small manual I put together on how to setup a *small* solar system. I'll post it when I find it. It's not that difficult to do on a small scale. There are some good YouTube videos on how to make the connections, etc. The tools needed are cheap: Harbor Freight crimping tool, bulk connectors from ebay (China Post), inverters depending on what you want to do, or battery controllers. Main advice is this:
if you buy panels, get the largest wattage that are cheap. Don't waste your money on 100w panels. Start with a 200+w or 300w panel. There are some crazy sales on those every now and then. CargoLargo was dumping a bunch a few years ago, and that kind of opportunity is not uncommon. And remember that DC only travels a short distance before significant losses; AC travels much further -- so place your inverters on or close to the panels, do the long runs with AC.
For 2018, here is what I like: smaller honest pools like what Marvell2 has done. I'd like to see others in the group follow. Solar power where you can fit it in like Phil has been mentioning. And I do think FPGAs are going to be the next wave, but that's just my educated guess. YMMV. Oh, and screw Bitmain. I kept an open mind on them until I experienced up close and personal how they work. How can a billion $ + company have such completely crappy service? Wonders never cease.
Edit: Please no more of these "kudos" to Vorrick or for that matter Zooko. Tools, nothing more than tools...
we Try to get 200-230 watt panels at 20 cents a watt or less. We can do this at auctions of new old stock.

you need 7 of them to run an s9 for about 5 hours a day
http://sepbatteries.com/trina-310-watt-tsm-310pd14?gclid=CjwKCAjw9e3YBRBcEiwAzjCJutlBzUkSK_DiijhNqGCna7eU7Zg0Va-bNCJ6om25iqvOLIgyzJiqjhoCDhMQAvD_BwEthis one cost more hard to get under 100 it is about 3 by 6 5 of these would be a 15 by 6 foot row. and provide about 1500 watts 5 hours a day . cost of 500
the key is find deals have space for a row.
you need an inverter/converter plus some wires.
if you have a spot and get this setup for 1000 bucks you could see 7.5 kwatts a day for more then 10 years that is 7.5 x 365 x 10 = 27000 kwatts of prepaid power so to speak.
So is it worth it ? well it makes mining gear of any kind earn money since the power cost is up front.
if you get 27,000 kwatts for 1000 you paid under 4 cents a kwatt.
as this project goes on our goal will be well priced panels and well priced converter/inverter as a diy kit.
I have multiple photos of a doghouse to house the miners
https://bt.irlbtc.com/view/4415357.msg39741539#msg39741539that doghouse setup is well under 100 bucks. So since the row of solar is say 15 by 6 or maybe 18 by 5 the doghouse size is not much of an issue.
the panels I show above are too costly at those links.
the 230 watt is listed for 101 usd it needs to be 50 usd or less
the 310 watt is listed for 145 usd it needs to be 100 usd or less
you need a 1600 watt inverter/converter with good warranty.
buysolar has 7 230 watts panels wired I have the doghouse setup we are waiting on inverters. to fully test.
As a small system 1400 to 1800 watts would be max. to be practical.
no grid tie
no battery
and
4 hours north 6.0 kwatts
5 hours less north 7.5 kwatts
6 hours more south 9.0 kwatts.
We are sure about the enclosure
we are sure about the panels
eth wires etc all pretty sure.
inverter/converter is our unknown it needs to be good and not costly and water resistantproof
