When it comes to crypto casinos that are VPN-friendly, I've had a positive experience with a couple that didn’t fuss much about VPN usage and had fairly quick withdrawal times. However, you'll want to double-check their policies on KYC because they can vary significantly, even day-to-day based on regulatory changes. For the no KYC preference, there are a few, but always be cautious and do your due diligence to ensure they are legitimate.
Well, if the casino representative did not clearly write that a VPN is allowed I would not use it. I haven't seen it officially stated on any site, it's probably not legal, but many crypto casinos allow it, but again I say you have to have a confirmation about it. If it is not from the forum but from support, I would take a picture and archive it somewhere just in case, it can help if there are any problems.
I used to use VPN to play in some casinos and I never had any problems, but again I didn't win anything big. So who knows, we should be careful anyway and have some proof that casino allow it.
On some casino there are representative would just say that use this at your own risk that's why we cannot get a clear answer since even them are so questionable regarding on the usage of VPN in their casino. That's why I find them unreliable since they provably will not help us if we encounter an issue like certain suspicious activity due to IP changes happened when we use a VPN. So I guess much better not to use this and stick on your real IP so that we can assure our safety in terms of funds confiscation and the casino will not have any reason to flagged us.
I also use VPN on some casino before but when I certain read that there are some people got an issue with this I immediately stop and there's no really big changes since I can still gamble nicely without worrying anything on certain possible issues that those devs would accused to us.
