I wouldn’t advertize anything, but some criterias to filter by: crypto payments available (that’s a good scrutiny even if you don’t pay with it), server location and legal address not in the vault 7 if that matters. The VPN installation itself is pretty easy, you can find guides on the internet or ask AI. I believe, on the official OpenVPN pages there might be a simple guide as well. You just need to use terminal and that’s all.

I use self-hosted on a cloud bought by crypto, but it’s primarily because my relatives living in a country with almost all VPN solutions and protocols blocked, so you always need to figure everything out yourself and try something new.
