But if you have free electricity, you can use any power, and that will be a profit for you because you don't have to pay the electricity, maybe you need to give attention for the maintenance of the hardware.
Who has free electricity? Certainly no large mining farm. I remember having read articles about how students
abused their university's electricity to mine crypto currencies, but they have been penalized for that.
Free electricity is scarce and if it isn't you generating it, you are subject to fair use policies which nowadays have prohibited mining and whatnot. Mining is a tough industry to be in, and I'm glad I always sticked to buying Bitcoin directly.
Throughout all the years, simply buying Bitcoin has always outperformed the returns that mining Bitcoin has generated. The same applies to investments in start-ups in return for a % stake.
Venezuela has somewhat free electricity from people there I have talked too on other channels.
The problem with this is the electricity company can cut off the power whenever they like and they have frequent brown and black outs almost every other night. So this can be rather concerning when your mining because you never know when the power will come back on so you will need to be there to switch back on the systems so to continue mining.
Even if people try to buy solar panel for free electricity this will cost a lot and even so over night the mining is stopped if can't store enough electricity, and also if electricity is not cheap not can get a profit over a month. Maybe in future will change if price will be high.
I have also wanted to find out more about solar power running a mining farm. But they would be limited unless you have a really expensive one to produce enough electricity to run even one asic 24 hours a day 7 days a week at full throttle.
The government subsidize these when purchased but only to an extent also reimbursing you every month or year. So if you wanted a higher power one you would need to pay it completely out of your pocket I would imagine.
