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.
