Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

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/whatever anonymously, 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? or maybe you guys can recommend me some foss mining apps which are safe that i could check out?

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 so ones that dont require a degree are appreciated.

edit: i don't specifically care about bitcoin. i just don't know jack about crypto and assumed that was what the usenet service providers would accept. if there's something else they'd take that is still anonymous, that's fine with me as long as you guys can help my dumb noob ass understand what to do.
