There are various ways you could use your computer for mining type activities but if you're not interested in the technology then I would say don't bother because unless you know what you're doing you would only mine a little and you wouldn't be able to keep track of whether it was making or losing you money.

I have quite a few mining rigs and they all make me at least $200 a month of profit, that has been up as high as $800 but I don't "need" them to do anything except mine what I point them at and because I love this technology and crypto I enjoy the process as well as the results.
