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.
Dont buy gpus now. The antminer E3 is too much cheaper and will drive gpu down the drain.
In general, mining is just not worth it now. Too much risk for this kinda return.
I really feel like the E3 will get bricked like the cryptonight variety did. Nobody likes bitmain these days.
