you can buy ipvanish vpn from any darknet market like hansa or alphabay, it costs 3$ lifetime, 256bit rsa encryption, suports protocols: openvpn (for normal use), l2tp, pp2p (for torrents), as they say they have 0 logs policy which means they dont keep any longs of any kind but it has limited connection speed, other choice is purevpn, but it is more expensive
You're not going to get anywhere with a free VPN; there's always a catch behind it. If you want a VPN that will do you right, you'll need to pay for the service. - It's as simple as that. Personally, I've been using IPVanish for a while now, and I can say it gets the job done.
