is it free power 0 cost to mine the sticks? if you pay power for those sticks to run.
lets say you use 6-8 watts for the sticks.
6 watts of power is 144watts a day
8 watts of power is 196watts a day
so between 4 and 6 kwatts a month at 10 cents your cost is 40 to 60 cents
if you spend 15 cents a kwatts your cost is 60 to 90 cents .
if diff was frozen those sticks earn 83 cents a month before power costs.
So they will stop turning a profit very soon.
If your power is totally free mine them.
I just checked. I only pay 6 cents/Kw so it's not costing me much to run these. I tried Peercoin. Still not as good as Battlecoin and pretty much the same problem as Bitcoin. It would just take too long to reach the payout threshold. So I guess I already found the coin for low hash-rate SHA256... Battlecoin.
