The issue is somewhat delicate, normally this in the terms and conditions of every site prohibits the use of VPN, due to international regulations the licenses are the ones that are governed to follow and opt for the prohibition of some countries, although the issue is merely political It tarnishes what has to do with Crypto and gambling, but there are cases that when writing to the platforms that are regular players, that can be subjected to KYC processes, could enter as special cases and allow to play and have fun, of course it is a possibility that exists .
^ Probably because my assumption is every idea that could be a gate of fraudster were not tolerated on the gambling site especially if a gambling site was running a license under the country that very strick on implementing KYC and VPN is a tool that can be used by any fraudster that can be hidden even in the country that prohibits in all kinds of gambling. Nevertheless, it is good if we avoid using any VPN service in a gambling business or a business that includes a financial system. VPN was most likely use in the dark web or black market, not on gambling or even trading.
