Exclusive or not, it is still going to be bad idea to use VPN. I think somewhere I have read they do allow it but it has to be white listed IP and most importantly the country should be fine with gambling sites. Otherwise the player is doomed for sure.
Exclusive mean a dedicated IP bought for himself for privacy reason and you are right that casinos allows usage of VPN but it often used to abuse the bonuses so if someone wants to use VPN then they need to do it right way.
And if the country where the player reside restricts gambling then which itself a no situation so using VPN for that is like a bypass and will be considered as a violation.
I honestly don't see any advantage for people to use VPN in casinos, I say this for the following reason, let's suppose that Duelbits.com accepts citizens from all European countries, so a person who was born in France and lives in France starts using the casino Duelbits.com and uses a VPN with an IP address from Italy, this person thinks that this is having greater probability but some time later the casino asks this person to do kyc and that person does kyc, he hands over all the documents from France and passes on kyc, so you have a verified account but continue using a VPN with an Italian address. see that the casino already knows that he is a French citizen, he has already done KYC at the casino, so what would be the point of him continuing to use a VPN with an IP from a country he doesn't live there?
By this I mean that with the advancement of KYC measures, it has become useless to continue using VPN even when only casinos allow people to use VPN, even when people enter an IP from a country that does not belong to the list of restricted countries. Unfortunately, the time for anonymity, the time for privacy, has already ended. With terrorist attacks, with many cases of money laundering involving terrorists and countries that suffered sanctions due to their involvement in genocides, governments have become more serious in combating money laundering, mixers are an example of how governments are acting tough. a few days ago we had news that the ceo of binance stepped down from the direction of binance due to accusations made by the US government against him, all because kyc was involved
