Casino sites have already made kyc very easy. Sites without kyc can gamble using a fixed amount. so I don't think there is any need to use vpn either. there is a fear of account blocking if you use vpn so it is better to use sites without using vpn. Since gambling is not officially legal in my country it is very difficult to access casino sites in my country but I can use the reputable casino sites on this forum without vpn. Some sites do not work with sim ip but through isp connection is running smoothly
In some casinos, the KYC process is simple & easy, but some casinos are pretty complicated when it comes to KYC verification, they ask a lot of info. Many crypto casinos don't have mandatory KYC, but they will ask for that if they suspect that a player is breaking some casino rules... regardless of whether the player is using a VPN or not.
I have used a VPN in many casinos but never had a problem with that, I used it only to play some slot providers that are restricted for my location. And only in casinos that stated here on the forum that using VPN on their site is ok as long as we don't break casino rules... double accounts, claim different bonuses more than once, etc. I still play in those casinos, and they still didn't ask for KYC.
To the funny aspect of this, some of the available VPN are not free, users will have to subscribe for them and pay, yet i don't know why many have developed love for the use of this same VPN not minding what it may cost them, we have to understand the the gambling systems as well have developed technologies that helps i the identification of the use of VPN, we shouldn't bother ourself much on that for use.
Free VPN is not working great most of the time, it's very slow and sometimes it won't connect. There are also some other potential risks when using a free VPN, so if you wish for a quality connection it's better to pay for that. I guess it's the same thing as with many other things in life.
