Antminer E3 output 180mhs with electricity draw of 800watts, it won't matter even if it's patched, that 800watts will drain 99% of your profits and you will be mining at great loss unless you have free electricity and I believe there is no such thing as free electricity
Not everyone pays high power rates
I have 3 here running and they run 197-210mh each @ 768-779 watts each depending on the power rate you pay they are profitable.
If you don't mind can you tell me which country you are from and how much you paying for electricity at kwh ? I'm just curious because 768 is too high I believe, also ETC algorithm is already patched to support 4gb or 3gb VRAM miners
