So whats the point of the mining, I'm wondering if there is something dark your computer is used for while doing the mining, because otherwise, what is the benefit of your machine running all day long.?
YES! You are perfectly correct. There is no point to confirm transactions for the blockchain. There is no benefit for people running their computers all day for non-miners to send and receive bitcoins. And you are also correct there is something dark about bitcoin, it can eat your dogs so be careful.
