If you have a GPU and you’re just playing pixel worlds and doing general things like watching YouTube, I suggest that you begin mining Ethereum.
I have a RTX 2070 which I’m mining Ethereum with, and I get profits of 5$ (6, due to it heating my room as well)$ per day. I’ve also turned off my radiator as to only use my GPU for heat.
Why use my radiator for heat, when my PC can do the same thing while making me pocket change?!
