Hosting could be an option but it has a lot of hidden costs and issues.
For me if I could have a nice generator with free fuel I think I would mine before I host.
Or cut a deal with one guy looking to dump his miners.
Lets say he gets a good 50kwatt generator. And one guy brings him 30 s9is.
The deal they do is 50-50 on the coins mined.
His cost is the 50kwatt generator. He gets the coins from 15 machines.
The s9i guy gets free power for 30 machines and keeps coins from 15 machines.
This could work for op.
The gear will always earn money.
My concern is the risk involved. There is effectively no way to test the health of a natural gas well. The pressure and line size can only give you a rough idea. What if I commit to hosting a bunch of miners and a month or two later the well stops producing? What if a generator fails and leads to downtime? What if a weather or other event causes peoples equipment to get destroyed or stolen? There is a lot of liability and risk involved that I do not feel comfortable with offloading to others, with nothing short of hiring a lawyer to draft a contract.
