Yes but what's the point of an incredible deal on a piece of equipment that only makes money if you have 1 cent electricity?
Rich
By Monday even a free S5 will only be worth turning on if your electricity cost is under 10.5 cents kWh.
A free S7 is only worth turning on if electricity is under 18 cents per kWh.
So even if the miner is already paid for there is little point keeping an S5 if it cannot cover the electrical cost. So expect to see cheap S5s.
(Note - based on 1 Terrahash generating 5.44 cents USD per hour.)
On paper you are right. The prices of those miners should go down.
But make sure to check out the market place please will sell their miners for prices which will never give you ROi.
