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?
I have 5 complete rigs with 6 cards on each (AMD rigs 570 & 580 4gb and 8gb) and a "test rig" that has 2 GTX 1070s on it right now. Total cards is 32. I have 1 card being RMA currently (XFX 570 4gb) and when its replaced ill be back at 33 cards.
I have unlimited electricity for a flat fee at my house ($230+tax).
