I’m curious as to what HN’s VPNs of choice are. I personally use IVPN and Mullvad.
AirVPN You can use openvpn or wireguard as clients (or their own), and while i was writing this I just saw they accept payments with different crypto (bitcoin, ethereum, litecoin, bitcoin cash, dash, doge, monero)
The other big point in AirVPN's favor is configurable port forwarding. Makes it much easier to quickly expose something to the internet on any network.
