With the KYC criteria, it'd be hard to give a recommendation as most of the top crypto casinos that i've been playing at more or less have an optional KYC page together with their own specific KYC rules, and eventually, it'll be unavoidable for most high rollers but if I could recommend a few casinos that are less strict with their KYC rules it'd be bustabit and bustadice. The only downside about these gambling sites is the games, both of them only have one game but the rest checks out.

There is a contradiction between the title of the thread and this sentence. I take it you want non-kyc but you wrote it wrong in the title. Anyway, have a look at this thread. You have all the information you are looking for:

Information of Crypto Casinos License and KYC requirements

But do you know that you must prepare yourself for KYC with the amount you are mentioning is even the hardest thing to have without passing through KYC processes. Though there are some site that may consider you with little amount if withdrawing without going through such process but seeing that you have a very large volume deposit/withdrawal will such affect you to go through kyc.
Keep in mind as a gambler who gambles online must be ready to expose himself or herself to KYC it's unavoidable requirements from casino site.

Op have mentioned about his wagering that has made him no.1 in blackjack.fun and nowhere he mentioned about the single huge withdrawal requirement. Looking his wager, he's a whale gambler and his winnings seems to be high. However if his plans were for huge withdrawal then it is quite hard to find such platforms, if not most of the platforms provide support with limitations.

There are actually lots of different casino sites that will not ask or require you to submit KYC but if you're a high roller, they will still ask you to comply with their KYC before you withdraw your funds. I don't think complying with the KYC requirement will harm you. Your details and personal information are safe as well as you're using a highly reputable casino site.

Since most of casinos in this forum have mandatory KYC rules, there's only few casinos that free KYC e.g. Freebitco.in, Anonibet and BCH.games. Freebitco.in have a good reputation in this forum and the representative are very active, I recommend this casino. While Anonibet and BCH.games seems there's no activity anymore, so if you have faced a problem, you will be hard to contact them and their reputation isn't really that good.

It is possible to play without KYC, but it might get more complicated for you since most of the reputable casinos will ask you to provide your personal details and documents when you want to withdraw larger amounts. If you google KYC free casino, you will see a lot of results. However, since gambling has become so regulated in many parts of the world, it is not as easy as it once was to find a site that allows you to sign up without having to complete the KYC process. It used to be pretty common for some crypto sites to accept people from all over the world without having to go through that process, but those days are gone.

As Don Pedro Dinero already mentioned, there is a thread by Mahdirakib where you can find basic information about the KYC requirements of most of the casinos promoted here: Information of Crypto Casinos License and KYC requirements, but I would still confirm that information with customer support before depositing funds at any of the listed casinos.

I've read in the thread of Duelbits that the staff/representative himself said that there's no KYC there unless you haven't seen any unusual activity with your account.
But with the high rolls/bets that you'll do, it's likely that you'll be subject to KYC whenever you withdraw. You may try if you want and talk to the rep there since they're very approachable and there's nothing to worry about since most of those factors you've mentioned, have it.

Thanks for the typo notice and link, looking at it now

@Don Pedro Dinero, has provided a link to the best casinos here, there are casinos that require KYC and casinos that do not require KYC, you know every gambling site has different rules, in my opinion even though the casino does not require kyc, but if you make a withdrawal outside the rules above the specified limit, I think the casino will apply something to you in the withdrawal process.

Maybe, there are some casinos here that don't require kyc, but in deposit and withdrawal it's not up to 2000 BTC, normal, but I think with total withdrawals or deposits above 2000 BTC I don't think the casino will let you get away with it, surely one method will be applied to you, whether it's kyc or freezing and so on, to pass withdrawals.

For me it's better for you to use a normal casino site and bet according to their rules, even if it's not kyc.
