It is not really recommended to mine using laptop, you won't earn enough to cover your electricity and the possibility of you ruin your laptop is big, so instead of earning money you will lost your money and your laptop will be broken
I will use a solar panel for that purpose and my laptop do not require much electricity.
I heard it for the first time that with mine my laptop will be ruined? Can I know how will it destroy my laptop? I do not think that mining is that much dangerous.
