First thing first, as long as you are gambling on a centralised casino, you should be ready to hand out your documents for verification any time you are asked to do so, and to see a cryptocurrency casino with centralised status that gives you total KYC free withdrawal on any amount is somewhat rear and hard to see, unless if you want to continue gambling below the casino trenchhoold because majority's of the centralised casinos have the benchmark of $5000+ as their benchmark for KYC demands on both withdrawals and deposits, you as a gambler can decide to operate with bellow that limits to keep your account free from being ask for KYC.
Unless you want to go on a decentralised casino who are totally KYC free, that way you can be rest assured that you won't be bordered with KYC at any point in time, but anything other than that will result into you relying on semi decentralised cryptocurrency casino, semi decentralised in the sense that, their are centralised casinos but not to hard about KYC and that way many players mistakes them for as none KYC casino, whereas in the rules and terms of service is included that when you deposits certain amount or  you win certain amount, you will be demanded to go through KYC.
