Now mention those decentralized casino since @OP wouldn't know what's the sites that actually a decentralized casino. In decentralized world, you don't need to trust since you can verify if they're completely decentralized and wouldn't ask you to submit KYC.

I think blackjack.fun asked him to provide KYC, that's why he search another casino that's completely free KYC and can gamble huge amount money.

Take note 777coin is still offline, not sure if they're suffering a technical issue because it's already around 3 weeks while the site promise to give update for the next 24 hours on August 13.

Well, even it there is a casino that is no requesting KYC it is complying with all legal aspects required for that kind of sites?
In caso of an issues... how to handle it? If they are not complying...
What to do if the possibility (or rather the obligation) of having to have KYC is introduced retroactively?
There is a topic on a problem that a user had in the board scam accusations that involved an exchange (I avoid linking and posting in favor of one or the other party) but in any case this is a fact/possibility that must be kept into account and which can create problems in the future. Maybe NOW they are not requesting it but you don't know what they can decide (or force) in the future...

Actually most of the players need of KYC Free casino,it was not strict to the high rollers.I think you confiscated high rollers,because of their betting amount is high as compared to the normal traders.If you confiscated on that basis,it may be the real one.Blackjack is the trusted one and we don’t have any doubts in it.You had said,it had 2000 Btc.I had not aware about it,it’s look like you say huge about them.May be your statement will be the true one.Because it’s based on the gambling,So the gamblers with huge money.They will bet 1 Bitcoin as the bet amount of the one game.You no need to worry about the holding money in it.Better you should look the loyal of the website like Blackjack.With my experience,if the website without kyc.Surely it will had less amount of withdrawal limits.I had not discussed the pro of the Blackjack,you need to investigate to get good knowledge about any website.

We must be willing to complete the KYC procedure because all casinos have added it in their regulations, although the KYC procedure is not yet mandatory unless you have a trace of suspicion and high withdrawals, but as long as there is no suspicious activity and withdrawals are below the withdrawal limit then you don't have to worry about completing KYC.

Sorry, you missed the point of this topic. I recommend reading the original post if you haven't already. Even the title mentions the term "high roller" so it's almost certain that he won't be gambling with small amounts. We can assume that the same applies to his deposits and withdrawals.

I do not think there are casinos like that anymore, you could avoid going through KYC if you were a small gambler at most casinos, but if you are a high roller then I am sorry to say to you that you will have to eventually have to endure that process, this is probably not the answer you were looking for but things have changed since some time ago, as governments are more interested in this market and especially in people like you which wager a lot of money.

Well the sad part of gambling is that mostly nowadays is asking for KYC, wherein it's really too hard to find legitimate platforms that has no such thing, however if you found one it's very skeptical as well especially if you used to gamble a huge amount of money because there's a lot of scammers out there.

True true. I'm sure anyone with a large amount to withdraw will need privacy but I'm also fascinated by his will to wage 2000BTC when you can just do it with a small amount after all casino limits the maximum also.

I was under the impression that casinos with no license will not ask KYC but yep, there is no escape for people who has a huge amount of BTC to just make transaction easily.

And that's the simple reason why he won't find one.
It's a lot of money and will definitely be in question how he was able to reach that kind of amount or just simply how he accumulated it.
I would be careful if I have that money.
Tax evasion is the first problem.
Now you are looking for ways to gamble it away which means more questions.
2 BTC should be enough to start in a reputable casino KYC or not. You don't want to be putting your BTC in danger by depositing it with an unknown gambling site.
