What to mine [Newbie]

Hi guys and girls! I am just wondering what is worth mining in 2021 when you have free electricity. I mean something small and portable to stash in a room with free power and let i run. Is there anything that could give 5$ per day for example or something similar? Thanks!

Depends on your hardware. Check: https://whattomine.com/

yeah, i got nothing. Even my PC is a standard pc, nothing special about it. A purchase is necessary (would prefer something below 1000$)
