When you guys are mining with your laptop isn't this really bad for your health of your laptop. And when you are doing what kind of software are you using.
Software: I am using Windows 10 but I heard that Linux sometimes has better results because their kernel is very different.
And why would you use your laptop? Build your own mining PC. That's a solid investment because: The worst case is that you can't mine any coins anymore but then you will still have your hardware. In that case you don't have a total loss. ROI happens very fast and let's face it: It is highly unlikely that you can't mine coins anymore or that the power costs are higher than the money you get for your coins.
