what if someone want to buy one of your rig? how much would you sell it?

assuming your rig are 6 x 470 and mining zcash they are doing , $170 a month net profit right?

so around 10 months roi

right now paying to you more than 10% plus the electricity cost would kill the point of hosting

because at every 10% added it's like paying 3-4 cent more for electricity
