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.?
The point of mining is to earn money really. That is the reason most people do it. However, it is not very profitable at all when it is done in small configurations, however, huge mining farms earn a huge amount of money daily. I was watching a documentary about one just the other day and the electricity bill was 1 million dollars per month. Not kidding. Something dark on your computer? I don't think so. First of all, no one really uses their computers to mine Bitcoin, they use these things called ASICs, which are specially made just for Bitcoin mining, and mine Bitcoin at a much more powerful rate. The only dark thing that I can see, related to Bitcoin mining, is the fact that you are basically pushing your graphics card to the limit, and if you are using a laptop it is even worse. You run the risk of your hardware dying, or at least severely shortening it's lifespan.
Mining will help you to gain bitcoin for free. However, it took to wait to gain that bitcoin. Some people do mining because they want to gain bitcoin without any hassle. As of now there is lot of people do mining and it is very effective. I think many people were happy because they get free bitcoin in mining sites.
