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
I do not think the net profit is $170 for the rig.
1400 sol give you roughlty 0.21 btc months, minus electricity is around $170
btc price is very high now almost 1k
