Because of KYC verification which is now done by most crypto casino to know the people who gamble on their casino, I think anonymity is no longer a benefit of gambling with cryptocurrency in crypto casino.
Am i wrong to think that this information on the internet needs to be updated.
Usually, you are asked to provide KYC documents when you win a lot and try to withdraw. But there is a way to avoid KYC verification.
If you are a regular gambler, you'll definitely notice that you are in debt and you have never won more than what you have lost in casino. So, if you deposit 1 BTC, win another BTC and plan to withdraw 2 BTC, if you are an active gambler or just a gambler, more likely after some days or weeks, you'll come back and deposit another 1 BTC, then you'll more likely lose this 1 BTC and you probably deposit another 0.5BTC or 1 BTC. Finally, you are spending back what you have won. So, just leave the balance on your account, don't withdraw, just gamble from the balance that you have because that's all you can, you can't beat casino and come with winnings, otherwise casinos wouldn't exist. So, just leave the balance as it is, come back days or weeks later, gamble and repeat. This way, you'll avoid KYC verification while still be able to gamble anonymously.
If you care about winnings and think that you are not going to lose what you have won, then just simply don't gamble and do some other activities.
