Usually web3 casino offering this no KYC feature, But for other out of that thing maybe in future they require this especially when there's something to look at on their users account. Also when they had been hit up by certain regulations just like what other big casino experience.
Like a centralized exchange can launch their DEX, Web3 wallet but if they began as a centralized exchange, with known founders, co-founders, their team are known by governments and they are already under radars of governments for any law enforcement in future. KYC and AML will be required by governments even with DEX, Web3 products from the centralized team.
But guess they don't bother this for now since they are new and maybe the only thing we could expect that maybe in future this KYC requirements will be ask to their players.
They will not do this if there is no order from governments.
It's certainly that if governments send that order to the team, they will obey it shortly because it will keep their team are safe from legal threats, and it will also help their business operation continuation.
