As long as using a VPN is not a problem for Duelbits, I don't think it's a problem either, but you really have to ask their service support if you can use a VPN and provide reasonable reasons why you use a VPN. Indeed, some people always want to appear anonymous, so they don't want to reveal their original IP. whereas in my opinion it looks like a child, but as long as it makes him comfortable there is no problem with me.
It's also important to confirm that Duelbits doesn't ban VPN use if that's not a problem I think using a paid VPN is the solution because it guarantees more security than using a free VPN because I've used it and it sucks having to share with other people and it's hard to access the site in the end That.
Duelbits still allows VPN use and as long as your country is not from a country blocked by Duelbits, it seems safe. But using a paid VPN is better because you don't fight over IP with other users. And people who still use a VPN may feel safer when they can use a VPN to browse the internet where we know that there are lots of crimes that can cause us to lose a lot of things including data.
But we also have to be prepared if Duelbits asks us to do KYC one day. Maybe they just want to make sure that we are only gambling and not related to any illegal activity.
KYC has nothing to do with using a VPN in my opinion, and KYC is required only when there is something suspicious about a player's activity, but indeed you should use a VPN only to unblock an Internet Service Provider, not to unblock because you live in an area where playing is prohibited at Duelbits casino, and if there are players who persist with this, don't get angry when their account is finally blocked because when doing KYC they are caught from a prohibited area, because the casino will stick to its rules when a country is included in the prohibited list, so forever it is off limits unless there is a change in the rules, and the rules applied by the casino will refer to the license where the casino is registered.
