Depending on location if you have a decent amount of property you could build a solar farm, this is the only way to even try and future proof your location. You buy property, put solar power on it and host, use the hosting money to help build up against the invested amount while also using half to buy your own miners.
So you take container oil cooled filled with miners x funds you have or want to spend
Add this
And a bit of this
Wouldn't it be more profitable to mine then?
If we speculate anyway why not underground for location , Sahara , dunno how much it cost m² but can't be a lot , enough sunshine and temperature variation to generate electricity , at first glance the only big problem would be a stable internet connection.
Anyone has free satellite ?
