But yeah, I guess that the reason is the free electricity.
Good luck and happy mining!
There is no such thing as free electricity. Either the cost are diverted to someone else, or the electricity is plain stolen. Either way not really a "happy story" for the one paying the electricity... eventually...
Example: even if mom/dad is paying the electric bill, they (all, incl. OP) would be better off just giving OP the money being spent on that electricity...
If he's stealing the power, then it's bad.
If he's living with his parents and uses the power they pay for, then it's bad.
But what if his dad built a small water / wind "mill" in the backyard and that produces the power?
Why do you assume people guilty just like that?
I still hope for a good and fair story.
