Actually, that's the best way to ask if a user is unsure about any terms involving the use of a VPN.
Admit it, there are users that even reading the Terms and Service seriously and focusing, can't find the section referring to the use of VPN. Because they were unable to see that, they will assume that using VPN isn't part of the team.
At least by asking the support directly, a user can get a direct response. Optional but just for reference in case of the account is being sh*t because of the use VPN, take a screenshot of the chat where the support responds that it's fine to use VPN.
When I read the topic, we should not confuse the OP. See what he asked:
Crypto gambling keeps growing faster than Fiat gambling, it's good to see that the masses now favours crypto for gambling than using Fiat but the only issue I have with crypto is the security, data breach and co so I want to know if hiding my IP on a crypto gambling website is secure? I am going with a premium sub of express VPN. If you think otherwise please tell me.
Know that VIP can be secure and not secure, free VPN are not secure and you should use a paid VPN which are better, or use the free version of a paid VPN, like Proton VPN.
If you connect to a website with VPN, it adds nothing to your security, but a way to provide anonymity. Follow what harizen said that you should ask the customer care before using VPN if it is not stated on the gambling site ToS.
