Looks like you can just put it into a calc and see yourself
10 contracts at 0.0185 each is 0.185 btc
That gives 10gh
Pays 0.0008 btc each day to you
So thats 231 days to break even at current difficulty. Or $7.40 to earn $0.033 daily per contract I think it is
Thank you
I knew it would be an easy calc but didn't know where to look for the current difficulty, as I said I have no idea on mining but think I will be spending serious time learning as it really interests me.
