You can still mine bitcoin without power or hardware all you need is a pencil and paper

Yes, it’s real. The SHA256 algo. Bitcoin mining is simple and can be mined using a piece of paper and pencil. So throw away your hardware computer or actual miners, save power electricity bill. Get your pencil and paper out and start mining, solve simple math. Nah, it’s not going to get harder, but sad thing is it will take you couple thousand years to hit a block 🙂
