I see them popping out more recently, they have open source code, no registration, no kyc and they are accepting cryptocurrency payments.
Mullvad is probably a better service, but it's always good to have some alternative opentions available.
Thank you very much for sharing that VPN, it looks very interesting and it is the first time for me to hear about them but it seems that they are an old VPN service provider because I found topics about them since 2014 (haven't dig much). Seems, they haven't changed their UI since the first day but their FAQ section and overall structure of information is very different from others. From quick view, it looks like this is a privacy focused VPN but they accept BitPay for crypto payments, c'mon.
I would stick with IVPN or Mullvad. I don't want any room for headache. By the way, from quick research, many people complain their service but I'll try to find more info about them in the upcoming days.
