Would yall reccomend using your main pc for mining when its not in use?

It absolutely will affect your PC in the long-term, particularly your graphics card. Think of mining is overclocking your GPU - not something you want to do for hours on end.

Unless you're wanting to just dip your toes into the world of cryptocurrency mining, I would highly advise you do not use your everyday computer to mine cryptocurrency. Crypto mining is not profitable unless you don't pay for electricity or if you have well over $1,000 to spend on components upfront to build a powerful mining rig.
