I thought that it should not bother me. But it turned out that my device is participating in mining, and I did not even suspect it. Be more careful.
How can this be possible, also how did you know it was mining?
If you see unusual usage of your GPU/video card/HDD it means that something is running that you never noticed.
And it's possible that its mining through any of those and the cause of it is you probably clicked and downloaded a malware that contains a mining software.
