Crypto gambling keeps growing faster than Fiat gambling, it's good to see that the masses now favours crypto for gambling than using Fiat...
I seriously doubt that. Fiat casinos have been around for decades and have a huge head start for crypto casinos to overtake them just like that. Crypto gambling is becoming more and more popular, but there are millions of gamblers who play different games and sports without ever touching cryptocurrencies.
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.
It doesn't matter what VPN provider you use. If VPN usage is banned on the platform you play on, the type of VPN doesn't matter. It's just a matter of time before they find out or suspect that you are using multiple accounts if some other players connect to the same servers when gambling at the same casino.
If I were you, I would speak with the customer support and ask if VPN usage is allowed. More importantly, read the TOS agreement, and see what they say about it there. The TOS is superior to the information provided by the support. If they don't mind that players use VPNs, make sure you are only connecting to servers in territories that are allowed on the casinos. Most casinos don't allow US-based players from playing, so don't connect to a US server, for example.
