Hey Craig
I have a smaller rig and currently it costs me $150 a month in power. I pay like $.20 kWh
My costs are so high im going to send my rig to a friend who has a company in Nevada. He is going to host my rig at his place for less power and a small fee.
I have a combination of my rig + Steem + lending and Genesis and hashflare ( I wanted to diversify cloud mining). I have a hashflare referral code if you like :)
I'll be honest I like your idea of putting in some Hashpower . It could also be calculated based of previous difficulty rises.
Lower your costs and diversify risks!
Cheers!
