Also one of the concern of free VPN is the potential to share IP with other casino players that violates terms. You might get connected and freeze your account even though you are not with them. Premium VPN is a must.
This should be most important for players who use free VPNs, maybe they are not cheating but the IP is the same as other players who are cheating so that it affects our accounts, unfortunately players often don't realize this, and because they are reluctant to spend money on premium VPNs they end up with things that are detrimental to him, so if you really like to gamble VPN should be included in the equipment for gambling.
