Can people take advantage of this if we setup a Mining Pool or something like that?
A lot depends on how much power you can provide.
Also how good is your internet connection?
Also where are you?
USA a state is enough info.
Not USA what is your country?
4 cent power is good.
So pretend you have 3x 30 amp circuits of 240 volts.
that is 90 amps .
an s-9 is a modern miner it uses about 5.5 amps at 240 volts.
so 4 miners is 22 amps a 30 amp circuit that is good since 24 amps is max to be used on a 30 amp circuit.
you could do 12 miners safely 15 miners not so safe.
so the 1 miner cost for a month at 4 cent is 40 usd for you you want some profit so 60 usd would mean you make 20 bucks a month on each one.
that rate of 60 for an s-9 is very competitive with other hosters.
Not sure you want to charge that low so 65 is 25 a month for each miner in your pocket. I do not count anything but power.
no net costs no other costs.
Plus people do not know who you are and will not want to send gear to you.
Lastly these miners are really loud and really hot. So dealing with heat and noise will matter if you run 15 or more.
