VPN won't help you much trust me, if the security agencies of your nation wanna find you; VPNs can't do much.
I sincerely think that running a dedicated tor node for the purpose will be better than spending money on VPNs.
Why not possible to hide my Ip address? So many premium VPN company still provided such opportunity to keep anonymous, there are no problem to use crypto even also you are not belong in any crypto friendly country, if government did not monitoring that. You can use TOR browser here your browsing history will be encrypted.
