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.
