Most casinos are VPN friendly but when it comes to KYC Most of them often make that VPN connection as an excuse to freeze funds of the players.
Sorry, but this is not correct. There are a few casinos that are VPN-friendly and that state clearly in their ToS that they allow the use of VPNs.
Regardless of whether the casino is VPN-friendly or not, the most important thing here is why you are using a VPN.
Most casinos won’t care about it if they know you didn’t do anything against their ToS, but they (including VPN-friendly casinos) will ban your account and confiscate your balance if they suspect you are using a VPN to bypass any of their restrictions or to try to cheat them.
