I am saying its more than like free here. 2.5$ is not an amount which you can compare. And Its not illegal. I was referring to the companies where they always pays the bills but you can use the electricity as much as you want. There is nothing illegal.

You can choose two different things
1. Follow govt. rules and pay a constant money and put your miner in an unknown place.
2. Put your miner in a company workplace where there is electricity is reproducible.

I am not saying anything unethical here.
