I'm doing a test with setting up a cheap order at nicehash.
And mine at zpool.ca.
If everything goes correct, this would be a nice way to make some small profit.
(this could also be useful for some projects)
So i set up a order with a amount of 1,1575 BTC/PH/day
With a speed limit of 10 TH and invested 0.015 BTC.
(This gave me roughly 31 Hours of mining)
The pool at zpool.ca has at this moment an average profit of 0.0017 mBTC/GH/day
So if my calculation are right this will give me small profit of 0.0007 BTC
