how to get bitcoin anonymously (or where to find out)? - Divisions by zero

i’m wanting to get on usenet but remain compeltely anon (vpn, anon purchase, etc). i know this ins’t stricly a piracy question and is maybe more of a crypto question but figure there ain’t nobody who knows privacy and anoniminitry like you guys do. so if i want to some amounts of bitcoin anon , how tf do i get it? liek not large amount, just small shit like to buy subs for a few for usenet indexes and whatnot?i know the bitcoin atm’s and banks do know your customer stuff (basically they id you first) and are not anon. have hear d that you can mine it anon but not sure if apps track hw specs and whatnot that could be used to id you. is there another ways that dont require you to have sepcial sms accounts or burner phones pr whaetver first? i’m on linux ifg it matters for good mining aps. i can write some bash scripts but im not a super hacker or anthing.
