I’ve noticed some scam accusation posts against certain casinos, and there seems to be a trend here.

Some casinos advertise themselves as KYC-free, but the moment you win big, that’s when they suddenly put all the requirements on you. And it’s not just basic KYC, they ask for heavy documents like passports, and some even request bank account details.

So I’m wondering, is this really a legal safeguard, or are they just using it as their own policy to forfeit players’ winnings?
This is actually a serious concern. Most of us might not have reached that level yet, but what if one day we do hit it big and end up facing the same situation?

definitely scammy and shitty behaviour if u ask me

even kyc casinos close ur accounts when u start winning constantly

The community can at least provide more elaborate answers if you can tell us what casinos you are referring to that "advertise" themselves as KYC-free but ask for documents once their user has won a big amount and tries to withdraw.

On another related reason, maybe there are footnotes under the term "KYC-free", especially when winning a big amount.

But anyway, is KYC still a concern for gamblers nowadays, where every industry is implementing KYC even for crypto-related services?

This is the reason why you must be selective in choosing casino to gamble with, most times these newly launched casinos are worth to be prevented regardless of what offers they tends to people it's another way to lure people into using their gambling site to gamble. I can't just used any casino to gamble apart from few selected and trustworthy casino that I knew after winning I wouldn't find it that difficult or hard to make withdrawal from the gambling site. Again, as a gambler we should also have it at the back of our minds that this casinos could ask for kyc at any given time and if they are kyc casino it would be ideal to pass kyc first before starting making deposits to gambling site to avoid stories that touches.

I've read a lot of casinos especially here that once you start winning it's either they will delay your withdrawals by forcing you to have KYC and after that they will reject it and probably just close your account without any notice and won't tell the reason as per their "Terms of Service" which sometimes I find ridiculous but we can't do anything about it since we agree to it once we signed. Honestly forcing KYC is common and since they will be releasing big amount of money they need to verify if the player is playing legally or in the jurisdiction where their gambling site can legally operate.

So in short, KYC is not scammy and purely legal since it's their compliance with AML policy but using this to delay the payment, or whatever reason like breaching the terms of the site, is a really scammy one.

This is usually the doing of shady casinos, so if you want to minimize the risk, go with highly reputable ones. There are casinos here in the forum that are very popular, maybe the most popular and they clearly announce that accounts need to undergo KYC first before playing.

That at least gives you some security that your winnings won’t be held hostage later on just to force you into KYC. I think it’s better to go with casinos like that. Not sure though if all others follow the same practice.

Most of the time, online casinos validly claim that they are "KYC free" initially but require kyc documents subsequently if you go beyond the threshold of their bets. In order to know absolutely if a gambling casino is indeed 100% KYC free, then you may refer to their ToS and read their guidelines, rules, and other regulations posted.

Is this unethical and deceiving behavior on their part? - ABSOLUTELY


Then I guess I have no other choice but to submit my documents and hope for the withdrawal of my money. In the event that they refuse to honor my withdrawals despite submitting all the required documents, then I have no other choice but to seek help from their CS. If this fails, then reporting them to forums and other platforms can get their attention.

Every licensed and regulated casino has the right to request for players KYC information any time they please. So, do not be deceived that a casino is KYC free when that casino is regulated. Some might have it on their terms and conditions stating that they have the right to request for the KYC when ever they want, it could be after you have made a deposit, after you have won a huge amount or after you have even gambled for a specific period of time. Some unregulated decentralized crypto casino will not ask for KYC unless it is licensed and regulated but if not licensed, I think they should ask for KYC.

It is why before you decide, you should search for more information about the casino. You will prevent that from happening to you because you know. But if that happens to you, that is your call whether you want to do KYC or let that money go to the casino, keep the money. I feel that is bad for gamblers because they don't know about those requirements and they should ask a representative or send an email related to that question. Maybe that happens in shady casinos where we can not get more information so we can skip the casino and search for others.

They often have a card to use in their TOS, maybe stating they have right to change their TOS at anytime or some might state when they can request KYC from customer, which some may even say at anytime but if the customer do not go through it carefully, they won't see this and miss out thinking the casino is fully non-kyc.

Someone looking for a non-kyc casino or platform should be ready to do more findings like reading customers review and the likes than usual in order not to be tied down by some annoying TOS.

First, they tell you you can play anonymously, but as soon as you manage to win more than 1,000, you magically can't withdraw it normally and must show identification. Furthermore, the payment method also changes; they decide how to send it to you.
So, you're forced to accept to receive your money, with the risk of receiving nothing at all and also risking your privacy, which is something to avoid like the plague.

It could be an excuse to delay the winners and to see if the scammy casino would find a valid grounds to not credit the winnings of their winner. Lots of scam casino did this from the past and even if we already provide those documents they ask still they didn't release the funds and turn down those valid request done by their gamblers.

But there are for compliance and verification. We can notice it after we submit our documents and they release the funds after we are cleared with those documents they required.

That's why picking reputable casino is the best thing to do, so that we can avoid this kind of troubles.

A casino site mentions everything in their ToS. If they have mentioned something like that in their ToS then of course they can do it so for that you have to read the TOS of that site carefully before gambling. KYC is now being gradually made mandatory by all casino platforms. To protect money laundering because many people try to mix their illegal money by putting it in the casino. So casino sites can have such a requirement that KYC will be mandatory for withdrawals above a certain amount of money. So it is very important to read the TOS to be clear about everything

In that case, I think we should already be aware that KYC can be implemented anytime. Some casinos advertise that they don’t require KYC, but if we check and see they’re licensed, we shouldn’t fully trust that claim. They can always use their Terms of Service in their favor.

If we don’t have the required documents ready, it might end up being one of the biggest regrets of our gambling life, winning big but losing it all because we weren’t prepared for KYC.

According to your details, it is an excuse to cheat. Since they have to pay a lot of money to a player. That is why they feel a bit contraction to take it in the mind.  It is then that various problems are pressured on him, even compulsory to complete the KYC. However, the casinos are licensed by the government. They could say all the verification or KYC at any time, it is very normal. However, at present, most batting sites and casinos cheat. Because everyone operates online illegally. And it does not take any action from the government and they can easily disappear. That's why we have to be careful all the time. So that no illegal casino is cheated. And I will always try to keep my identity secret.

It may not be a good thing to happen, but if we've been aware this is going to be asked upon registration, that will be legal. Many casinos, not just scammy ones, ask for KYC after winning big. But as long as we've been confident that they can be trusted, it is not a problem. But if we feel something fishy and a scamming attempt, to leave is the best decision. Therefore, we consider looking for the trusted sites even if they give no bonuses rather than those who have an attractive offer but compromise our personal information.

I don't know much about non-KYC casinos practicing this act, but I can definitely tell that some KYC betting companies do this a lot despite the customer's KYC from day one. I actually followed up with a case of recent, where the whole issue got heated, leading to so many users calling out the betting companies and the celebrities that promotes them as well. From a legal point of view, a non-KYC casino shouldn't ask for KYC especially when it was never stated anywhere including in their T&Cs. But, that's where the thing becomes tricky. They always find ways to add these things in the T&Cs, and we all know that most people don't even go through these things. It is a common thing for KYC casinos though.

So, I feel if a non-KYC casino ask for KYC when it wasn't stated in any of their policies, then it should be considered a shady activity.

It is! I think crypto casino should not have any KYC on their system.
what is the essence of having crypto when you will be ask for a KYC? Crypto is an anonymous currency online wch hide the identity of its holder with the crypto wallet.
then the casino will ask for the "know your customer" for the biig withdrawalss? thats not safe!

Maybe they want to protect their business and ensure that they won't get into AML stuff, which could somehow be their way into being regulated and legal. I believe this depends on your wins because they have a threshold for how much you can win or withdraw.

Don't believe their advertisement? Check their TOS and make a screenshot if they really offer no KYC. A reputable casino should be truthful about what they advertise and what's on their TOS. Casinos will eventually ask for KYC because they need to verify that you are abiding by their rules. You're not violating any of their terms.

If you're a diligent gambler, you should see this coming, and you are aware that asking gamblers to do KYC is imminent; no casino can last implementing a no-KYC feature, as they open their platforms for abuse and exploitation. This no-KYC promotion is just an advertising hype and deception.

This is common on crypto gambling sites and it is not when you win big but when you win. They make KYC compulsory but they will allow you to deposit without KYC but you will not be able to withdraw if you win until you get verified. This act is dubious in my opinion. Stake is not like that which is the reason I like the gambling site. You will be required to get verified before you will be able to deposit.

But if you mean the gambling site only do that when you win big, maybe it is part of their ToS.

Not new. They do this most of the time because they think they can get away with it. But they are mistaken. There are still a few who will fight against them and I think the government should be more strict with letting online casinos be licensed.

This is the only way to prevent scammy online casinos from getting in, and if they are forcing KYC just because someone won a big amount, I think it's a fishy strategy to run away from paying the winner.

That's the puzzle in the world of gambling that has not been solved at this time, I see a situation like that also happens to a famous casino and a good reputation and I see what makes it made The accusation is a beginner with a different account, whether it's a puzzle between gamblers or casino owners, back to each other.

Sometimes I see accusations of unreasonable victory claims, up to $ 500k - $ 1 million, how someone can win that big, isn't there a minimum limit and Maximum, so this is really confusing, which is clear if it is said to be "legal or fraud" both, but I don't know one of them, players or casino owners.

We have already discussed this here before multiple times and this behaviour from casino sites is not appropriate.
KYC details if required from a user should be asked before he deposits any money on the site.
If there is any cap on the winning amount which directs towards KYC then the user should know that beforehand.
It should be mentioned in their Terms and Conditions clearly.

The first thing any gambler should do before signing on a casino is to read the terms of service. Some casinos include in the ToS that withdrawal of certain amount would be subject to KYC. Some of them genuinely request it because they are mandated to comply with Anti-Money Laundering regulations and policies of regulators or licensors. 

The casinos have the right to ask for documents based on their rules. And bettors should be able to submit them. But some of them asked for strange documents which might be complicated to get because they don't want to pay the winner. Such casinos should be reported to the relevant agencies for retrieval of the wins and sanctions if possible.

There is nothing legal about any casino enforcing KYC on individuals after a big win, when at the beginning they stated they are KYC free. It is understandable if they made it clear that KYC is important and the gambler didn't pay attention to that.

Honestly, I dont want to believe that new casino go about reusing/copying FRD from old reputable casinos.

Basically it is pretty common practice and I cant judge a casino ask for KYC after big wins as scam, the main point should be after the KYC is verified, what the casino do?
If they process withdrawal after verified KYC without too many drama, I will not call the casino as scam but if the casino do something like too many excuses to delay or even to make players unable to withdraw the big win with unclear reason, I will call it scam.
So the point is not about when the casino ask KYC because most casino has written terms, usually it is written as "we reserve the right to ask KYC at anytime..." or something similar.

I remember a casino representative who stated that those who are winning big are a threat to the casino and they don’t usually want them to continue using their site because to them they are not good for their business, while those who are losing big money to them are their favorite customers.

To me, it’s a scammy move - if you didn’t request it when they won little amount then I don’t see any reason why you’d start requesting for it when they managed to hit a huge win. To me if you don’t want people to win huge amount from your casino then limit it so they don’t lose huge amount and also they don’t get to win big, it will be a win-win situation for both of you and not that scammy kyc move that they usually pull.

Any casino that does this needs to have their names reported on the forum for us to know and avoid before hand.

I know that there are casinos that even though they do not make it known explicitly that is, you can sign up initially make a deposit and play without needing KYC. Your first few withdrawals, they may not even ask for KYC but after some time they do. This one is not a scam because if you read their terms and conditions, they usually say that they can request for KYC to be done at any time. However, if there is no mention of this already, then they are scammy.

I believe its a little bit of both.

On one hand, the casino is not totally wrong in doing this.  They have a bunch of AML laws that are just insane that vary by jurisdiction.  When suddenly large amounts appear on their books it raises a red flag with regulators that the casino needs to prove where this money has come from, and where it will go.  Thats a legal obligation, and if they dont comply, they risk hefty fines and potentially losing their license.

But lets be blunt about the other side of this.  Theres definitely some shady operators out there that leverage this kind of practice as a predatory business practice.  They entice players in with the "no kyc" or "instant withdrawals" promises and get them to deposit and play.  Then, if a player hits a big win, the operator suddenly pulls out the KYC card, and then proceeds to make the verification as hard and dreadfully frustrating as possible, in hopes that youll either quit, or make a mistake that allows them to legally forfeit your winnings.  Its a scummy tactic and Id be willing to bet that it happens a lot more often than people want to believe.

This has been a serious case in some casinos that have been dragged around the social media, an even here in the forum, if a casino claims to be KYC free at no point is the request for KYC after win justified but then some casinos practically includes the fact in the terms of service or T&C then at any point which they claim not to feel safe with you gambling and requires your ID then it's not a scam attempt but if they don't then it's obvious a very good strategy to forfeit gamblers win when it's big and beyond regular wins.

Its not a trend at all, some can report for scam accusation in the right and wrong manners, this makes them all not to be  legit, except for few, while some sites that have been accused of scam don't even exist on this forum or been represented.


Most times, a reputable gambling casino will not demand from you the gambler what is not on their terms and conditions, but because many don't take their time to read all these, another reason to use a well reputable gambling platform that can be trusted on whatever thing they do without being biased.

It is not the best situation for any gambler, i cannot defend that, because if i won big and i am faced with unending kyc requests, i would be pissed. However, i don't think many of these casinos advertise themselves as no-kyc casinos, it is true that they don't ask for kyc when you register and when you deposit, but even if they don't, i know that a casino can request for my kyc at anytime.

What would be best though is if customers are made to pass kyc before depositing, so they know that if they win, they are surely keeping it.

It will well within their rights to ask for KYC verification at any time. But if a casino use this as a method to avoid paying the huge wins they will lose their reputation and go out of business so they don't have to do that unless they are suspicious about something.

Bank details or proof of deposit in general is asked as part of AML and this triggered when someone deposit an amount and try to complete the wagering requirement and try to withdraw the funds as quickly as possible so that leaves the casino with no other option than suspecting the user is trying to launder some money.

Mention one casino that you've observed to have practiced such a malicious stunt, then everyone here will take better precautionary measures to avoid falling a victim. I was thinking they wouldn't even mention that to you; like, they don't advertise themselves as a KYC-free casino, only to ask out of a blue... They just don't request for it all and that makes any gambler very comfortable, until a meal ticket shows up.

Although, it may look like they're always trying to forfeit people's winnings, but no... They also need a system that must have anyone trying to claim the winnings confirm that they're "You" before payouts can be made.

To be honest, this is a very serious problem for us as users, it feels very unfair but we are forced to do it to be free from fund retention, popular casinos are not immune to problems like this, casinos sometimes free us from low withdrawals for a long time, but when you win big suddenly a traffic jam comes, the common reasons for casinos are bonus abuse, multiple accounts and others they only claim unilaterally

There's legal protection, or the casino uses its own policies, as outlined in the ToS.

They claim to be KYC-free in the thread title, for example, but the ToS states they can request KYC at any time. This means that with every big win, you'll likely be asked for KYC and more advanced documentation, such as passports, videos, and bank statements.

It's not unusual for big wins to be more heavily scrutinized by casinos, and this is a concern.

If they changed the rule on the fly, then obviously it's a scam. I heard casinos inserted KYC on their TOS because someone win big in their casinos. It's a no-no specially if they advertise themselves as KYC-free.

But there are still casinos that are still KYC-free so that's where we should play. And there are casino that are mandated by the casino gaming commission to do mandatory KYC upon login, so that is a big risk that we will have to take.

Is it just winning, or when the gambler tries to withdraw the winnings? Because I've seen casinos that have rules on their ToS that a withdrawal of a certain amount will trigger a KYC process. Anyway, if a gambler were asked for KYC just because they won a big amount and haven't tried to withdraw yet, it is kind of suspicious. I mean, apart from them using an excuse of "investigating" something, I can't understand why they would suddenly want you to do KYC just after winning a big amount and haven't tried to withdraw yet.

Also, this is why reading the casino's ToS is extremely important, there are casinos that advertise themselves as "no-kyc" but then in their ToS they require the gambler to do KYC at some point and usually when withdrawing.

It is better to boycott such casinos that do that, it means that they can’t be trusted and when an accusation is raised against them, it is a sign for potential gamblers not to use their services because they’ll deny them a big win one day. If they claim to have noticed some kind of cheating during the games, there should be a way for them to investigate and let such gambler know but asking for their KYC information is already breach of agreement between the two parties.


This is exactly what I feel about them, this is their own way of making the player feel pressured and want to forfeit their win to them. You can’t come up with some criteria’s that was not agreed on earlier, that’s just a sign of unprofessionalism. Filtering out the casinos to patronize and not to patronize is very important even if they pose as a no KYC casino.

They are not using their own policies for these advanced KYC processes that they implement to their users. They won't just forfeit the winnings of these winners and that's why they're asked to.

The casinos are also followers of the regulations that are protecting them and so, they have to comply. I think most of the casinos nowadays are requiring KYC.

And those who wins a lot, as in huge winnings, they won't just be allowed to withdraw it without going through the verification.

What most users do, they'll comply to the KYC to get their money and after that, they leave and never comes back to that casino.

There are a lot of this cases, I won't name names, but if we look the one board, there have been piles of this case and it's hard to track whether it has been settled or not. One thing we might do first before registering is reading the fine print of their TOS as there might be rule that they will implement a KYC for big wins. So this is kind of a weapon now for casinos to used.

And then the dreaded thing, they will keep rejecting your submitted KYC and they will say that they suspect of a fraud and maybe cheating. So their is a big chance that you won't get your big winnings, and worst even your capital is going to be confiscated.

On a norm, any casino that makes KYC verification compulsory for it's users are supposed to perform the verification upon registration into the casino or during deposits because they can't place KYC on withdrawals and not also place on deposits. Some casinos will even make payouts on little wins without requesting for KYC but when the winning is huge that is when they will begin to use strict measures to look for problem where there is none. Even during KYC verification after winnings, some casinos still makes it difficult for their customer by pending the verification process which is wickedness. Any casino that is not licensed or regulated is suspicious and can scam their customers so it is better to avoid casinos that are not licensed.

It's a legal safeguard if they post it on their terms and don't mislead their players into thinking that they are not going to ask it, then they will ask it for verification after a big win.
We should not trust casinos with hidden agendas; they must be transparent about their postings and actions. If they are promoting their platform as a no-KYC, then they should hold it and don't just change their policy.

I think it is safer for gamblers to come to terms with the fact that they need to do KYC registration and verification before they're able to gamble generally. Because it has become a general trend for all casinos and for any casino not yet demanding KYC, you as a gambler should know at the back of your mind that it is just a matter of time before they change their policy on that and do what others are doing. If a casino says that they are KYC free and suddenly demands for you to go through KYC registration after a big win, to me that is a scammy attitude since that they know that many people gambling on a platform are people who are trying to avoid doing any form of KYC verification, hence their action is to try discourage you from getting your win since they know that the chances of you submitting your documents is almost the same as the chances of you abandoning the win because you are avoiding KYC.

If a casino puts that they are a KYC-free casino, then after a big win then they are quick to demand for KYC, they are scammers because why did they not tell initially that they would need kyc if you win big, but they would be quiet, and when you win they begin to look for means to disqualify you by requesting for kyc so that if you do not meet the requirements or criteria, they disqualify you and keep their money That is just the trick there so that they will say you are not qualified but they put that they are a kyc free casino, is that not scam?

Most times, they are quick to change their ToS because of a big win, so as to make the winners undergo a kyc before they can get their rewards and if you challenge their actions, they tell you that it is at their own discretion to chnage it at any time they want without informing the community as it is their sole right to do so at any time. What will you say about such actions, I guess you will call them a scam and yes that is what they are.

I have experienced this before in sport betting where i was asked to provide KYC after a big win, I would've loved to drop prove about what I'm actually talking about But i had this experience about 4 years back so I can't possibly remembered the platform but that's by the way. So after experiencing a Big win I was asked to provide my KYC details then i was scared because i have not make review about such platform meanwhile a friend of mine have been making use of that platform for long so i decided to reach him to confirm if he have experienced similar issue before he then said yes that he has experienced that before and he had no option than to provide them with those details but after that everything went successfully so I decided to do the same and it works but I was afraid because I thought after providing those details that they're going to run away with the money and also use my details to do whatever that pleases them ;D.

It is not a straight answer like you gave it because most casinos put it in their TOS that they have the right to demand for KYC at any time, so if after a big win they decide to ask for KYC to see the face of the winner, there is nothing wrong. It is not everything that the casinos do that is bad, the problem sometimes is that people fail to red their TOS before taking some actions. I know there are some casinos that would want to avoid paying out big wins, but reputable casinos have no problem with people winning.

I always check the disclaimer before believing that they're a kyc-free. I think it's all about marketing when they say that but, the real thing it's just for smaller amounts of wins. And once the casino notices that there's a bump to the amount you gamble and how much you're winning, that's where they're changing their rule because they've written it all along. That, they have all the rights to change the policies prior to abuse or anything in relation of verification and compliance to the government that they are part of its jurisdictions.

I don't think it's a scam as such, some casinos and exchange houses offer a basic service without KYC, then after a certain amount, KYC is mandatory, there might even be those that let you make the deposit in advance and ask you for KYC when you withdraw your winnings, this does not imply that it is illegal, although it is tedious, if it is a reputable casino you will get your money if you provide your information, many of the problems that arise here are due to the desperation of answers, and most of them are solved.

I'm not saying there can't be isolated cases, but that's how the world works, no system is free from failures.

If they are a KYC casinos, then yes, it is legal for them to ask for KYC anytime, even if it seems forcefully to you. They have every right to do so, it would be clearly written in their T&C. As for the non KYC casinos, no, they have no right to ask for any KYC, but I believe we have seen many casinos advertising themselves as NO KYC, yet they would ask for KYC at some point. They are clearly dishonest and somehow scammy to me, and which I would always avoid. IMO, there can only exist two kinds of casinos. One is KYC, one is Non KYC. There cannot exist anything in between, that would be contradictory!

Btw, can you be more specific about the casinos you were referring to? The ones that are forcing ?

Unfortunately, it's bad behavior, but most casinos that do this have included in their TOS that they reserve the right to request KYC at any time. This gives them a weapon in their favor that can be used against customers without the casino having a bad reputation. For example, the casino can confiscate people's money and say they are following their TOS because they detected suspicious activity.

So, even when the person passes KYC, they will simply block the person's account and accuse the person of having too many accounts because they know it's impossible for the person to prove their innocence because they don't have access to the casino's database to know if what the casino is saying is really true.

Those casinos that advertise themselves as KYC-free – if you check their terms and conditions, some of them actually do have a KYC policy, which they will state that they have the right to ask for KYC when they consider it necessary. It's just that some of those casinos don't know how to properly do adverts, while some purposely drop it just to deceive their customers, which is not supposed to be so.

Honestly, this matter is very complicated and has many answers, we cannot apply the same answer for every casino. For example, some casinos that were offering and promoting No KYC, later on they announced that they will change their policy, some other casinos did that without any announcement to not hurt their business and lose their customers.
Probably, they are just worried to make an announcement and lose their featured No KYC policy. However, that’s definitely a red flag to me, any casino that got forced for that or received updates from their license provider should announce that publicly.

In the other side, some shady and scammy casinos will pull that trick for higher stakes players, just to not deliver their money or pay them their winnings.

if a casino advertises itself as KYC free but suddenly it starts to demand KYC only after a big win, that is annoyingly misleading and it will give a scam vibez. Transparency is the key point here if they know they will likely ask for KYC for large withdrawals at some point!! then they should clearly state it from the beginning in their terms & conditions, not bring it on players when it benefits them. Changing rules after someone wins is just a tactic to avoid paying and unfortunately many shady casinos hide behind this statement a lot << we can change terms anytime>>. That is why it is always safer to stick with licensed and reputable platforms where the rules are consistent. because in gambling!! trust is everything and if a casino breaks that by being shadlike, then surely they have shown that they can’t be trusted.

I understand how disappointing it may feel when you think you're dealing with reputable casino platforms that displays no hidden terms and conditions for it users but realistically there's a side note which shows the casino isn't as transparent as claimed. This is just a scenario to tell you that the regulation might act less concerned about the Kyc but once you made a big win, boom, they begin digging out their hidden terms for you to go through the processes which you never expected such as the Kyc's. Even there in the conventional banking sectors you'll be allowed to do your small withdrawal transactions but once a huge amount of withdrawal has been detected, you'll be asked to do extra Kyc's with a more confidential documents required before you can successfully do your withdrawal.
This is why it's necessary to do proper research about the casinos to know if they've hidden terms before creating an account with them because, lot of them lacks transparency.

When casinos says, no KYC but are centralized casinos, what their mean is that, you dont need to go through kyc before your can deposits and play on the said casinos as long as you are using a minimal bankroll balance and winnings, but anything that make your activities to go beyond the minimum trench hold, it becomes demanding for them to ask for kyc from you in other to be able to process the big amount of transactions.

For me, i dont see anything wrong with that, since i will probably not have anything to hide i will definitely oht over my document to get verified and then get my winnings off the casino.

It’s legal since that’s the requirements of AML policy. What illegal is when casino keep rejecting a valid documents for the KYC just for the sake of not paying big wins.

There’s some cases that casino just ask ridiculous form of KYC just to discourage gambler to complete it.

But this KYC is stated on ToS so it’s completely legal.

If a casino advertises itself as KYC-free then all of a sudden implements KYC when a gambler won a huge amount of money, then I can say that the casino is not worth trusting.  They are doing a deceptive advertising just to get gamblers to play at their casino.

This can be considered a fraudulent activity where the platform advertises something but do the other thing.  I believe false advertising is illegal because it deceives its users.

Fraudulent advertising is not a legal safeguard but a way for the casino to forfeit players' winnings. If the casino advertises no KYC, they must adhere to what they have stated in their advertisement.

It's kind of misleading, there's half-truth in such advertising. The TOS usually states that KYC may be asked at any possible time, thus, it's not KYC-free, but they're quite lenient and it is not asked immediately when signing up, you'll get away with it for a few withdrawals without any issues. From a legal point of view, the terms and conditions is something that you agree, thus, you acknowledge the possibility of KYC, and they're perfectly covered. Is it unethical? Yes, but as long as they complete your withdrawal after submitting KYC, then I believe that's okay.

It is shady and scammy when the casino itself where one is gambling on is shady and scammy, if one sticks to casinos with a proven liquidity and spotless reputation then there should not be a problem at all.

Also, it is always advisable to complete KYC in advance if one is sure one is going to be an user of a casino in the long term, so if one happens to hit some jackpot, there will be no excuse for the house to release our money immediately so we can enjoy it as we please.

It’s actually completely normal. Using their site and making withdrawals is fine, but since they have verification levels, if your account doesn’t have KYC yet, of course there will be limitations on what you can do and how much you can withdraw. Asking for KYC isn’t a big deal nowadays, and you don’t have to worry as long as the site is legit, you’ll get your winnings once it’s completed, I don’t see any problem with that.

I would say it could be 1. to steal your money and 2. for legal reasons.

Even the KYC casinos often ask for hefty verification after winning, so this is not new, as it has some cheating undertones.

As for the legal reasons, though some casinos could advertise no-KYC but still fear the government and would want to obey the AML Acts when it comes to big money.

I've never been afraid to complete my KYC with any company. All I am concerned about is how to keep myself and my finances safe. And of course, the most registered and regulated casinos can still cheat you, it's all about integrity. So, let's hope and pray we do not be their victims. And let's try to choose wisely.

You’re correct, some gambler making it a big deal because many incidents in the post that user freeze his account after winning huge amount and ask to verify KYC.

Some of these users are genuinely winner while others are involved on shady activities such as match fixing and other exploits.

They mixed their issue on genuine winning that’s why it create a wrong impression on KYC.

I have a friend who was banned from a casino site after completing KYC. This happened not just once, if I'm not mistaken, four times at different casinos. He felt he hadn't done anything wrong he was gambling calmly and hadn't won large sums, but was simply trying to withdraw his money, meeting the minimum withdrawal requirements. However, after completing KYC, he was immediately banned.
My friend kept asking what he did wrong and emailed support, but still couldn't find the error. He now refuses to try new casino sites and only gambles on truly trusted ones.

They advertise themselves as KYC free casino, but we can check on their terms to prove whether it's real no KYC or just another temporary no KYC. If they're temporary no KYC casino, it's a misleading advertisement, but they're not scammy/shady for asking KYC because they have that rules in the first place.

I would be concerned with casino who really no KYC, but they ask KYC regardless what the reason is, this one is really shady.

Almost many top gambling casino make this way after the user big win make us have to verifying document ID if want withdrawal all winning fund, I remember well with STAKE.COM after huge winning at sport betting without few hours my account freeze until not available for accessing yet and they have classic problem about multiple account reason. If want getting back my account must verifying not only document ID but also have upload proof address until bank book.
Its not normal way of gambling casino account ask me have to upload proof address and unbelievable what for have uploading my bank book document, I leave my stake account and wont sharing all my document not matter have losses there are around 4k DOGE coins when place sport betting at football match I use Doge coin.

Lest share your ideas and mention clearly about casino gambling forcing KYC after big win.

Eventually all casinos will be following KYC, unless some sort of huge regulatory change happens from the governments to allow crypto usage.

Now since people join casinos and then have to be undergone KYC, it seems shady to the user. But from the company's point of view, they are all good because they are protecting their own business.

Being forced to undergo KYC for rewards, bonuses, nobody likes that, but then you have to move to another casino if you just want to continue playing.

I think it has to do with some countries regulation of anti-money-laundering and things like that.

Up to a certain threshold they can move money freely, but larger amounts require more checks and balances.

I think it's reasonable, considering that the amounts involved are quite large in general.

It's not a scam but of course It can be questioned....
Most of casinos have in place a forced KYC in any case for all players involved. Even if this is not really clear from their webpage, there is always some comments (even vague) in their ToS.
In the past, with a casino, I had the chance to analyze one of these scam accusation. I would say... not all are real complaints. Most of the times gamblers know very well that they are gambling without following rules or just making multiple accounts - value bets and so on.

Which is illegal anyhow, Casinos could write whatever they want in the ToS that doesn't mean a thing in court.
They could for example, add that in case of multiple winnings, they will only pay in cash at their home office, so if you win over 10k, you need to fly to Curacao, would that be legal just because they wrote it in their ToS?  ;D


If a casino can accept money from a stranger without KYC, then they can also pay that stranger the winnings without KYC. It is selective scamming, fishing for people who will not be able to provide such documents or who, for various reasons, have problems with their papers. For example, I had no utility bill in my name for a while, since while we were finishing the new house we stayed at my wife's previous apartment for three months. If they had demanded such a document during that time, I would have had nothing to offer.

It is true that you said with a statement about the KYC, after all, It is true that you said with a statement about the KYC, after all, the purpose of this KYC is for our own safety and comfort in terms of gambling precisely withdrawal. Although this is proposed by the casino when we are going to make a big withdrawal, we have to finish it, than the victory cannot be withdrawn so it is better to follow the direction of the casin, especially if the Casino has good reutation then don't hesitate to finish it.

If you are planning to deposit a lot into the casino and it's not strictly KYC free, you should at least make the effort to verify your ID (and maybe possibly your proof of residence) so that you don't experience delays and unexpected troubles when cashing out your winnings.

Makes sense no?

Applies whether you play at Stake, Rainbet, Rollbit, Duelbits, etc etc.

I’m just curious, are all casinos willing to process KYC verification even without a deposit first? I mean, just to make sure the account already passes KYC before we start playing. That way we can gamble without worrying later on.

Are there casinos that actually allow this?

I don’t think casinos do this just to block players from winning. From what I’ve seen, most online casinos have it written in their terms, even if it’s not clear, that they can ask for KYC anytime, even if they promote “no KYC.” If it’s a licensed casino, they also need to follow AML (anti-money laundering) rules, and that usually comes up when someone wins a big amount, especially on games from third-party providers.

The term “KYC-free” or "No KYC" can also mean different things. In many cases, it just means no KYC for deposits and smaller withdrawals. But once you cross a certain limit, they might ask for verification. So technically it’s still “KYC-free” for casual players, but not for big players.

It sound like they want to cheat, maybe hoping that you won't be able to pass the KYC verification since the reason why you first start gambling on the platform was because they don't asked for KYC verification from you.

On the other hand it's not so true, some times you are the one that failed to go through their terms and conditions, just because they don't ask for KYC details at first doesn't mean that they can't ask you later.

It's also a clear way for some bad casinos to cheat customers, as they will likely keep rejecting every KYC information you provide to them, and if you call them to justice they will claimed you fail to pass their requirements.

All you need to do is avoid bad online casinos with bad reputation.

I want to believe that issues related to KYC requirements should be somewhere in their TOS maybe they would not clearly specify exactly when they will ask for it, if nothing like that exists in their TOS then it can be considered as scam. You should not expect any casino to be very happy to pay out big wins, the reputable ones will payout as at when due to maintain their reputation but that is where scam casinos are different they will find ways to withhold the payment. We should have it in mind that if a casino doesn't ask you for KYC when you register with them it doesn't mean that they cannot require it in the future especially when you win big.

That’s correct - everything is transparent in the TOS. But the problem with us gamblers is that sometimes we don’t even read it before clicking agree. In the end, it’s us who’ll face trouble in situations where we win big and the casino suddenly decides to implement KYC.

That’s why we should always choose a casino with a good reputation. Even if everything is written clearly in the TOS, if the casino doesn’t have a good name, they might still deny your winnings or scam you. And if that happens, as the victim you’ll have a hard time going after them since lawsuits are too expensive, and most of us would just let it go because we have no choice.

You are right that those who gamble regularly on these casino sites may face such serious problems. I think those casinos should initially make KYC verification mandatory for every player so that later on after winning there is no unwanted situation. If they ask for important heavy things like passport and bank statement for KYC verification, it is really a serious matter. I think it would be right for us to abandon these casinos. I personally have not faced any such problem yet. If such a casino site asks me for any heavy documents related to this, then I will refrain from those casino sites.

Some casinos offers different tier level of KYC and their limits also will be based on it. For example at stake we can enter details and Upload an valid ID to get KYC level 2 verified but for further we may need proof of residence like utility bill or credit card statement or something and then video selfie proof.

If we chose a casino where there are KYC compliance then it doesn't make sense when the user complains while casino ask them for KYC.

Yes, many non-KYC crypto casinos will let you play without asking any questions however when you win big they will suddenly ask for your passport or bank records. Sometimes that is true for AML however sometimes it is just used to delay or not pay out your winnings. In fact licensed places are obligated to do KYC when there is a large or suspicious movement of money, these are well stated in FATF/UKGC's page, so reputable casino also clearly state that. But if you talk abusive casino they play with the dark side. actually it is safest to play only at licensed casinos, before depositing read the withdrawal T&C first,  try a small withdrawal then, and check the community complaint board before you bet big.

Even though it looks scammy or a wish not to pay, I would say that this is fair and legal. All the casinos warn that they might ask for a KYC anytime, so they dont violate anything. Also I think that they have to report big wins and display it in their balance or annual report. That is why they cant just write «transferred a big win to a no name», as well as from big wins taxes must be paid, that is why report if to authorities.

Lol, so they can't write transfer to person X in their expenditure, but they can freely write taken from X in the revenue column?
How could this be considered even remotely legal, taking money from strangers but KYCing them when they need to be paid?

You are either KYC-free or you request every document before allowing people to deposit, choose one!


Those rules don't apply to deposits? Or are AML rules only when you have to pay winnings?  ;D
I really want to hear one case of a non-KYC casino that prevented one guy from depositing because of suspicious behaviour, one example!

In reality, there is a legal validity to asking for KYC in a casino, so that a gambler cannot commit criminal acts. But if an institution approves KYC initially and later asks for bank account or other information after a big win, it may be illegal in some cases and may be legal in some cases. Especially if it is in a regulated casino, then there is no fear of doing it because there is a guarantee of getting that money, but in the case of any other platform, it may sometimes be a victim of scam. For this, the right decision must be taken according to the situation.

Thats what i dont really get, why would they even ask for bank info if a gambler wins big? like whats the connection? are they trying to check where the money comes from, or just using bank statement as extra doc to be sure the person who submitted the kyc is the same guy?

honestly it doesn't make much sense to me. can someone explain this?

I also dont get why they even need a bank statement. I’ve read some people doing this when they were required, but personally i dont remember any casino asking me for bank statement after a win was withheld. Must be that the casino is not really trustworthy, not one of the popular ones in the forum, so they just take advantage of gamblers who dont have much idea about the top crypto casinos.

To prevent that from happening to us, i guess the best option is just stick with the most reputable casinos.

KYC is part of protection; they ask if the gambler is the real owner of the account and to protect from hackers, but asking for bank details seems suspicious to me. How about if the gambler doesn't have a bank account?

Asking for bank details is too much just to withdraw your huge win unless they ask for the bank account where they can send these big winnings.

Bank details shouldn't be share to someone unless they use it to verify you are a legit person and to verify if the ID you submitted is exactly the same person who asking for withdrawal. Based on I heard some casino do this due to AML and GDPR. So I think if the Casino is legal then it's safe to submit a bank details only part with your name and address.
But for non license casino then that's risky.

Lots of crypto casinos really abuse the KYC requirements for their own benefits and it's a very sad situation that we have on the market, sadly there is also no one that will regulate things for us because no one cares about the power that casinos have and abuse. Btw at the same time, to be fair, crypto business has always been dependent on trust, so I would say that only gamble on casinos that have a very high trust reputation on this forum.
Btw there are sometimes cases when KYC requirement after a big win makes sense, especially when there is a fact of arbitrage betting or sold games or something like that but that's rare.

It’s unethical for a business that declares non-KYC on their ToS but later on ask for just because you win big since they don’t have the rights to do that.

Non-KYC means no license to operate so they are not allowed to ask customers documents because this is a requirements for AML as part of being regulated.

It’s scam for a no license casino to ask KYC.

But dont have to figure out or ask origin of funds, you deposit several millions and start gambling, compared to a situation when a guy deposit $10? They cant be a business who does not care where they receive big money from and send big money to? At least from experience working in a bank, you can send small amount to anyone, but you have to ask to provide documents if client created a large transaction. I think if you work with money, you need to have some documents for a big transaction and can not transfer it to a random.

That's actually true, I've noticed that, I have seen and heard many people complain about this same case scenario and it is a very bad behavior by this casinos and it shows that they have interior motive for doing that. This thread has just opened my eye concerning this issue, so we need to be careful on some casino to avoid our fund being trapped in it.

Definitely they are doing it for their betterment and to their favour and not a legal safeguard. And if we do hit a big win someday we will surely be affected by this situation and our fund may be trapped if we can't be able to summit all necessary private documents. If you ask me I will They are being scamy and people need to DYOR to know the best casino to gamble to avoid this type of scenario happening.

I don't think they able to know the money comes from because it's banks that know everything. I guess it might likely want to know if your financial are enough to made deposit in their casino, example if you deposit $10K and your bank account only record $5K maximum, for sure they will make another investigation where you can get a lot of money to gamble.

If a casino campaigns for KYC-free for their customers, then customers should also consider reading the terms and conditions thoroughly. The casino may include rules to request KYC only when there is suspicion about certain account activities. This is particularly evident when there are big wins or concerning betting, deposit, or withdrawal patterns.
Especially if the big wins are related to promotions that the casino is running. It may sound like the casino is trying to scam gamblers, but we do not know what schemes the gamblers are actually engaging in. There could be attempts to exploit bonus programs or abuse of several accounts.

I will call them dishonest casino for claiming that they're KYC free and ended up asking for KYC after a big win. This is because the casinos know that a lot of gamblers love their privacy and are looking for platforms that their identity wouldn't be revealed. For this reason, such casino come up with the No KYC trick to lure them into using their casino. You will be surprised that, some of these gamblers that are after their privacy will forfeit their big win in order not to disclose their identity. The casino will keep the money.

There is a new project promoting their brand here in the forum https://notokyc.com the casinos listed in the site are KYC casinos but the service said claims to support No KYC platforms which is not true. As a matter of fact, I prefer to gamble in a KYC casino that has good reputation instead of a No KYC casino who will later ask for KYC after a huge win.

Scammy advertisement imo but if it's written in their terms that they can ask for kyc anytime, what we can do? It's what we signed up for. Read the terms, not the advertisement.


If casino has mentioned, kyc can be asked anytime in their terms and upon completion of kyc they allow you to withdraw funds, it's fine.

Theres a high chance that this might not be a scam, it's even a way to maintain security. A casino might advertise themselves as casino free but I'm sure that there would be somethings included in the terms and conditions that a lot of people don't pay attention to. If you end up winning a large amount of money then it's going to be important for the casino to make sure that your account isn't being comprised

One thing I usually advise people is that before they go gambling into any gambling site it's always better to pass kyc especially if they have kyc level 1-4, at least they should be able to pass from level to 3 or even better pass the whole level 4 before going into gambling than going to make deposit before they start process their kyc. At this point they could found it very difficult to pass kyc since they have your funds in their possession, but whenever verification is passed it makes that difficult for them to find it any fault or penalized the gamblers.

Damn I faced this shitty harassment recently. Well I saw a pretty good welcome bonus on a casino recently and I thought let's give it a shot. I played on their casino, So I did have my balance on their web. For some reason it was detected an Ip change of  network and it was asking me to relogin . Which is pretty normal ig. When I was trying to logged in the login verification code I was not receiving. So I reached their support team through telegram . You can't belive, only showing the documantion of my property was left for them. Just a simple code issue they were asking too much from me. Even though I didn't send any kyc info to them. Idk why they did asked me those info.

It was completely jot professional and harassing to me. I tried after several hour and I received code. Withdraw my find and swear I won't ever use new casino for such welcome bonus.

Today it is normally. I think that it is a way to steal our money, but mostly you accepted the ToS and their there is something like "casino can KYC you anytime they decide".
And of course it is accident. After your big win.*sarcasm* I created in different casinos accounts(some times few accounts in one casino) and always i was KYCed after several win in a row of after big win.

Every casino does not have the same ways of operation, that's why some of them does not request for KYC immediately after registration. Also, a reputable casino is not supposed to keep your KYC pending for more than 24 hours as long as you have provided all the required information correctly. I have not seen any casino that internationally pen a customer's KYC for a long time after all information was submitted.

This kind of problem has happened frequently, but from what I know, if it happens at a reputable casino and the gambler isn't cheating, it's not a problem. On the other hand, most of the popular, reputable casinos on this forum require gamblers to complete KYC before placing a bet, or at least KYC level 1. So KYC issues are probably becoming a thing of the past.

Maybe if it happened to me at a reputable casino, I would. But if it happened at a new casino, I'd refuse to do it and forfeit my winnings.

I think the assurances that the casino does not ask for KYC are just one of the advertising moves. Big wins do not happen often, but in any casino, you can always face a request to pass KYC. Therefore, you should not be surprised; I would not rudely deal with the support, explaining to them my rights, since in any case, the choice of payment or refusal will be up to the casino. The casino is naturally not interested in a quick withdrawal of money, hoping to continue the game and thereby leaving the entire amount in their accounts. Therefore, they will ask for documents and dig into the history, hoping to catch on to an error that can be presented to the player. Is this legal? Of course not. Therefore, licensed casinos with a reputation are, one way or another, more reliable than all new casinos just starting their business.

That is normal. They don't want to let their money go to the gamblers. So they impose KYC on those winners and fill many requirements that feel difficult to fill. But that will not happen to reputable and trusted casinos because that means they can lose their members and be flagged as a scam casino. They should explain that in their T&C so people can read and understand the rules before they register. I don't know if that is a legal safeguard but if they don't write that in their T&C, that is abusing the rules and gamblers should not use those casinos.

Yea it also depends on what the court accept but is this not depending on the region where the casino is registered?

There are schemes which they may be able to pull off under some regions which will be favorable to them and in other regions not going to go pretty well in their favor. Some go for every means to earn not just profit finding loophole and other means to get customers money acting shady/scamming to them.

are they not supposed to be doing this BEFOREHAND? they can’t just spring this on a customer because the customers has to be informed before they even start playing otherwise they are withdrawing information from their customers which is probably something against legality

This identity verification process may be hectic, whereas there should be security to the system against illegal practises. The actual variation is in the manner in which the casino executes it either openly at the beginning or by concealing the rules. When a casino can be trusted, these rules are normally well outlined to limit the chances of misconception. On the other hand, when new conditions are introduced in situations where players attempt to draw winnings, then it implies unfair acts and cannot be disregarded. This vagueness can be termed as power abuse by the operator. Users will be more critical as they will only rely on the casinos that are constant and clear regarding their policies. It also reduces chances of loss and the gaming experience will not result in a feeling of being cheated or negatively affected as would occur with other games.

I can agree to this.

Another thing I can say is that it also depends on the terms of service of the casino platform. For sure, some users who are just signing up are not reading this. They fill out and sign up.
But for me, if this is on the terms of service of the casino platform, then for me, they have the right to ask for KYC or lock your account if you don't comply.

To be fair, some ToS can be ambiguous and hard to read. That being said, if notification is what we need, they can simply put a big info saying they can demand KYC at any given time. I'm sure most users will still accept that term simply because they wanted to win and get money, but they'll still get frustrated if the demand for their data or the process is just too long and complicated to the point where it feels like they don't want to honor their winning.

They may advertise as KYC-free but if you look into their terms and conditions, it is always the opposite. KYC-Free is just a marketing tactic.

As I understand it, casinos have to legally check who they give (large sums of) money. Otherwise they could get into big trouble with regulators when they are asked for a paper trail. It has to do with anti money-laundering and anti terrorist-funding. It would make sense for them to only do KYC for accounts that withdraw large amounts of profit rather than every account. Less work for them.

Why not just do KYC beforehand?

Some casinos would gladly accept offering non-KYC services. But they are forced to ask for identification because of government regulations. The government sees the casinos as a channel for money laundering and terrorist financing. Casinos also asked for KYC to avoid cheating and misuse of bonuses and other privileges. I doubt if there are any registered or licensed non-KYC casinos available in my location. Any gambler who wants to have a hassle-free gambling experience should just be ready for KYC.

Usually, loyal players will choose a site that's KYC-free and hassle-free. But I also think this is why, before actually playing, it's best to browse their menus if it's online and we can chat with them about deposit and withdrawal mechanisms.

The incident you described is also often heard when someone wins big and requires strict verification to be able to cash out their winnings from the site. If the requirements are met and complete, it might be possible. If even one item is missing from what they ask, don't expect the funds to land in your account. They want to keep coming in and don't want to lose. It's best to avoid playing there and choose another place that is more comfortable and transparent.

Many casino have tos of service about non KYC if your account dominance loss than win, regulation suddenly change if you got jackpot and huge amount of winning for withdrawing all. If keep continue to play without withdraw maybe not problem your account still non KYC but if want withdraw all winning fund from usually withdrawal instant will process manual until have upload document ID. Its risk if any casino restrict user from specific country will difficult for withdrawing their fund.
I agree your ideas who ever the gamble indeed the ToS gambling site allow for non KYC but must ready for verifying document ID, read detail all regulation of casino are your country restrict or not if some time asking for KYC.

That's why if you live in a jurisdiction with crappy law enforcement, it's a complete mistake to play on a shady platform that has stupid malicious ToS in the first place, forget the ToS, even your absolute rights will be thrown in the garbage bin, so at least stick with something that is at least registered in the said country. If that is not possible, try your luck with a casino that is licensed in countries where a license actually means something, like the UK.
Also, never forget:
Do you know your rights as a gambler? (https://bitcointalk.org/index.php?topic=5535631.msg65182302#msg65182302)

there was a topic before about this.


This particular casino rejected the user’s request to do an advance KYC before depositing $1k. The user was just trying to make sure he would pass KYC before playing with a decent amount, but the casino refused. So maybe some casinos will allow or even require KYC before gambling, but clearly there are also those that don’t.

It could be that the casino is acting shady, but it could also be doing it with good intentions. It all depends on the casino's reputation. I mean, a big reputable casino will maintain a good reputation, so when they ask for KYC, there's a good reason for it. However, new casinos might be suspicious, but among all of them, there are almost no non-KYC casinos. Players will find it difficult to find a casino that doesn't ask for KYC at all.

And I have experienced that with accusations of multiple accounts even though I didn't do that, in the end I chose to let go of the money because I didn't want to do KYC which requires showing my face.

You’re correct, some casino doesn’t allowed early KYC unless asked by them already since they just use it whenever a player already hit the deposit limit for non-KYC account or to verify for possible irregularities that involves other user.

There’s no changes if the KYC was done before or after if your account was committed an action that will trigger KYC and investigation.

However, there’s some scammy casino that use KYC to freeze withdrawal and avoid payment to users.

How can it be scammy ? It's legal 100% and most of casino do this as soon as someone hits a big win and it's perfectly normal to do so and also they can close your account so make sure everytime you join a casino , you read their terms&conditions.  8)

It can be scammy if you used a real shady casino with a very weak license and stuff...because a high trusted casino will never do this.

On average, casinos have players who win large amounts, especially new players, so casinos will usually implement KYC—this is normal as casinos already have rules in their terms and conditions, so they need to read them.

For me, it's not strange for casinos to force you to implement KYC after a big win, this is already common practice.

Just use casinos that already have a good reputation and are responsive to complaints.

But why they don`t KYC us when we lose?
I agree - it is in ToS and we have to agree with it if we want to play. But the same time today we have no choice - such clause is in the main part of ToSes. And i think that it is a kind of cheating. It would be more fair to KYC during the registration. They deposit money instantly and without any KYC, so i want to get my money instantly too. 

If a casino has to comply with any legal requirement, it will certainly ask you to go through KYC at some point. Serious casinos "want" to be regulated; this avoids problems for them; after all, they are businesses and want to remain profitable and in business. And we should consider that it's an extra layer of security for us customers; if there's an issue, we can demand our rights and have someone to turn to. A casino that doesn't require such verification, isn't regulated, could disappear from the internet at any moment, taking your money with it. So, I believe that if you don't owe anything, have nothing to hide, and your money is legal, don't worry about this detail. The trend is for all casinos and companies that provide financial services in some way to require KYC.

If they claim that KYC is free at first and then ask for KYC again later, then their behavior is definitely suspicious. Because they may be considering not to pay the money based on some issue. However, there is another aspect to this that usually when someone wins big, the casino company has to be accountable to the government for that win. As such, a casino company must want to make sure that they properly monitor the KYC of the person who won the big win before they send the winning reward.
