$5.57 a month for the miner's power.
$2.87 a month for the pc power, not including wear and tear for letting it run around the clock.
$1.20 for eBay 10% fee.
$.50 for PayPal's fee
It cost me over $10.14 a month the run this thing. So I ain't really making much of any thing. And you don't have to worry about restarting the miner every 24 hours when it goes down.
