Hey guys, I would just like to point out that many people who mine crypto currency rely on not having to pay for their own power. Let me point out the issue with that.

The fact that you are using someone else's power to mine can be wrong. It isn't much different from stealing money from your landlord . They have to pay the electric bill while you make money by using their electricity.

What I'm saying is that if mining crypto currency is built around stealing from people, then it shouldn't be used. Imagine if you were the owner of a couple buildings and each of your tenants was mining currency. Your bills would be substantially higher and they would be profiting off of you.
