........ if your waiting on your miner not paying the electric your waiting a long time. roughly speaking the 1.2 t uses 10% btc made daily on electricity and thats at this bismal price. if it was around the $5-600 mark again then it would be using only 3-4% btc made a day in electric. hard to guess but the machine will stop making elwctricity costs in about 5 Years if btc dif changes as it has. but by then the dif will hopefully have dropped due to ship jumpers and youll still make money.
