If I were you, I wouldn't use Opera VPN. First of all, they are owned by Chinese group, I don't think you will be safe with their VPN too and I I don't think their IPs are as clean as others from top-notch VPN service providers.
According to some reviews, their VPN service is actually a proxy service, so it is just a VPN by name[1]. Their server locations are so random too, unreliable even if you buy the pro version. It also fails to bypass some services, using outdated encryption methods, etc. I failed to find the report on how clean their IPs are, but no one should use them for sensitive service especially if they ban VPNs to begin with. Even if a casino or a crypto platform allows VPN, we should not use this service imo.
I also support for this, the use of vpn should not be encouraged because it usually comes with an unexpected endings, if the platform does not go against it, then the user might have been log time deceived with the effectiveness of the use of that vpn, i can also see that not all of them are reliable, then i see no reason why i should make use of a vpn if there is nothing fishy from what am doing.
