Moreover it's a headache if you use VPN (your country is restricted) then you won huge, how can you possibly withdraw the money?

If your country is ban on casino with Curacao license then there's a high chance that you will be ban on most of the crypto casino.
I think those restricted country only chance to play on online casino is from unlicensed casino or decentralized casino that doesn't have license at all. This kind of limitations is the reason why this people living on restricted country still risking to play on the casino using VPN to bypass it.
