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?
The OS you use doesn't really matter, what matters is what VPN server you use and to an extent what client you use. I've used AirVPN for about 3 maybe 4 years now with no issues and they allow port forwarding. qBitTorrent is a well regarded client and provides a setting to bind to a particular network interface (IE the virtual NIC provided by your VPN), this is much more reliable than a VPN client's killswitch feature.
