I still think it is worth it. depends on your strategy though.
I checked my pool address just now and I am expecting 1.9 ETH a month (went up by .09) and I pay $230 for unlimited electricity for my house. I know this number can fluctuate based off of difficulty.
I am not worried about the price per ETH at this moment because I am still making close to $800/month at todays prices. I am mostly mining for the coins at this point though. I am looking for a big jump on prices throughout the year and will sell at that time.
What kind of setup do you have to make 1.9 ETH / month?
Probably around 25-30 GPUs depending on the cheapest GPUs you can get. You would need 3 motherboards to run them. Then these would probably run at an estimated electric power consumption of around 4000-5000 watts. These are very rough estimates. I wouldn't get into buying GPUs for mining at this time tho. Too much is uncertain.
Right this second, you need appx. 800 Mhash/sec to earn 1.9 ETH per month - that would be 26 Nvidia 1070 models or 28-30 AMD RX 470/480/570/580 models.
Power consumption presuming WELL OPTIMIZED rigs would be around 3000 watts on the Nvidia side and 3500-4000 watts on the AMD side.
The AMD option would be lower up-front cost at current card pricing.
My power bill for 4 KW continuous power draw 24 hours a day 30 days a month would be a bit under $160 ALL fees and taxes included, and I could drop it to about $110 if I lived one county over.
In my case, the actual numbers are a bit lower for ETH income, a bit higher on power use per rig (the R290 rig eats a LOT more power than a 1070 or Polaris rig would but since the cards are long paid for and ARE still profitable), but the majority of my income right now is from ZEC not ETH.
I DID just drop my electric bill by almost a third, when I shut down my A2 Scrypt farm 'cause it wasn't even breaking even any more *BEFORE* factoring in cooling costs (though evap cooling is CHEAP, and a lot of my cooling is forced-airflow).
