Im very paranoid about getting into piracy and im not sure if i should or it or not but there are so many things i want that i cant afford.
is there a secure linux os that i can use without a vpn? im pretty use to windows 10 but i was told linux mint is good for this kind of stuff, is that true?
No need to be that paranoid. If you want to be basically bulletproof, pay for a cheap seedbox hosted in a friendly country (ultraseedbox is a good choice), and do your torrenting there. Then use any free or cheap SFTP program to transfer it to your computer.
Plex or Jellyfin are good ways to view the content either directly from your seedbox or off of your local computer, and I know that Plex has encrypted connection options. Jellyfin probably does too.
