Bitcoin Forum

i registered at an online casino and my deposit was not arrived(in casiono) and i contact to their support and they said you need to wait for 10 business days for your refund.

10days are completed and i still didn't received my refund, and they told that "if you don't receive your refund in 10 days then you can contact us with your bank statement"

my question is, is it safe to share bank account statement for verification purposes?  the site is reputable, but in bank statement all my information are available. is it safe to share?

Good question!

If you want us to understand the situation then you need to share some details. Please tell us the name of the online casino. Please go through their FAQ and post it here where they said about withdrawal. We will also need to know the currency you have used for your withdrawal.

In the end this topic is not related to Bitcoin. Please post such topics on the Gambling discussion board (https://bitcointalk.org/index.php?board=228.0). The reason is simple as you never wrote Bout Bitcoin and you are asking questions related to gambling. ;)

First, this is not the best fit here under the Bitcoin discussion; your deposit was not done using Bitcoin.
Another thing is: did you read the T&C of the platform regarding privacy before you started using the casino and made your deposit?

Being safe or not being safe all depends on you. If you think the money you deposited there is not worth your privacy, then you can forget about it and don't send your account statement. But if you really need your money back, you don't have any other option but to give it a try and provide them with the required documents. What you can only do is, before you upload the document, cover up parts that you think will reveal your personal information and compromise your privacy.

Edit: I was typing when @elevates comment popped up.
Just move your thread to gambling discussion and list the name of the casino; maybe they have a representative here on this forum, and other members with casino platform experience will suggest remedies for your case.

The casino don't need all the information so you can probably hide the important parts like account name or number and even balance. Since you are disputing that you haven't receive the refund then it's only natural to show proof that it didn't arrive. There's no better way to do that than your bank statement.

Choose a better way next time. If you're worried about revealing personal data then you could choose sending from a non-custodial crypto wallet and using it for your withdrawals and refunds.

I want to understand clearly, what do you mean by your deposit has not arrived. Do you mean you funded your casino account wallet? Or Withdrawal from your casino account directly to your bank account?


Another question is if you are concerned about your personal details being out, did you do KYC verification where you were required to submit your passport and proof of residence? If yes, I want to believe that your information is already out there. On the other hand, if you are concerned about the security of the site, is the money something you can forgo? If yes, then forgo it. If not, send in the bank statement but blur out personal information you wouldn't want to be revealed.

Bank statement won't expose your private keys but keep in mind filtering the information you will be sending. Also, it is for me fishy in a way that I haven't experienced gambling sites asking for my bank statement rather than transaction history
 But if you think that the site is reputable enough, then it could be worthy of compliance. Bank statement only includes previous transactions as well as balance but if there is other way to get your refund then that would be better ofcourse.
Problem is if such information is required by the gambling site. If that's the case then the player has no other choice but to comply in order to process the refund. However, following transactions would be somehow worrisome so I guess moving to other platform would be a better idea.

I guess this casino is just giving him a hard time and buying time, not sure what a casino needs bank statements for while we use crypto. If this is true, it is a paradox, only the government has the right to ask himto make bank statements.

Totally agree with you on this point, personally, providing a bank statement is also not difficult, it is no problem but exposing your transactions, the harm is small.

You already have said yourself that the website you are talking about for verification is reputable. Now by reputable, I think you mean that the website is famous and it is sponsoring some famous football teams around the world. Your data sharing is in your hand and your call. No one here can force you to share it. If you want to get KYCed, you share it.

can you share the casino that you playing? because it's my first time hearing about this problem usually a casino only asks if they suspect the user of fraud or cheating the casino.
you just want to refund your deposit then they ask for your bank statement?

well, since you are reporting that you have a problem at a casino it is only fair that you say in which casino you are having this problem, this is extremely important information because it can help more other people to use their bank account money to place in the casino, other people will be able to use other deposit options like using cryptocurrencies. this is the first point you should do: say the name of the casino where you are facing this problem

now the second point is about your question, firstly 10 days is a long time, usually the maximum I have seen on other sites since years that I deposit it using the credit or debit card it can take up to 5 to 7 working days (Saturday and Sundays do not count) and the same happens when and even when withdrawing money from abroad (website) to the bank (debit or credit card) it takes 5 - 7 working days, with Saturday and Sunday not counting as working days, so this is the first time i hear about 10 days

third party on the bank statement there is no information that compromises your bank account, no bank in the world will put your password for your bank account on the bank statement, there is no such thing, the information that will appear on your bank statement for the last 30 days if you ask for 30 days, then only all your transactions that you made in the last 30 days will appear, your full name, your bank account number, your residence address will appear, you cannot hide anything that is on the bank statement when you deliver in the casino, you cannot edit the photo.

Before you send the bank statement, check if you have a password on your statement, I'll tell you again that the bank statement doesn't have anything that could make anyone other than you have access to your account, but in any case, check before sending them

So are you depositing at the casino with crypto or fiat? Usually when depositing with crypto it won't be a problem as long as you actually send it to the casino wallet that is provided.
But if your deposit doesn't arrive, even waiting 10 days for a return so the casino asks for a bank statement to match the transaction, maybe I just assume it's the fiat you deposited.

Depending on you, some even do KYC more than that by asking for proof of savings more than 6 months in advance, to be honest, I've never experienced this kind of thing.
If you think the casino's reputation is good then it's legal for you, if it's a concern then it's better to avoid giving up the lost money.

If you want to verify your bank at the online casino that you mentioned, in my opinion it is safe, not an obstacle for you to do, indeed on the bank receipt that you sent and verified to the casino there is your name and account number, but it's not fully displayed by the bank receipt, example: 3583xxxxxxxx that's what is visible, except for the sender's and recipient's names, the bank knows exactly which ones to keep secret and publish.

To get your money back from the casino you are referring to, just verify it, if they require it, if indeed it is a condition that must be sent.

I used to experience something like you at a fiat online casino, I also did bank verification, to get my money back, for now it's safe, it happened in 2020.

I think it's safe if you play at a big casino, after all you play at a trusted casino and maybe you've completed KYC there so why worry about that, cover any parts that shouldn't be published as long as it's not a screenshot but an image in the form of a file original and all you have to do is prove it to the casino so that you get your funds.

I thought why use a bank account if in the end you know there will be a problem like this, even though crypto is much faster to use in deposit transactions at casinos and even more anonymous than using a bank account, but hopefully this problem can be solved and make it an experience for you in order to use crypto to play in the casino in the future.  ;)

It shouldn't take up to 10 business days but maybe each casino has its own policy so if a user complains like you, they should wait. But if it's been 10 days or more, and you haven't received your refund, you can contact the casino again to see or ask if the process has been completed or not.

If you register at a trusted casino, you can rest easy on handing out bank account statements for verification purposes. After all, the casino will protect its members' data from hacking or other bad things. Or maybe you share other documents besides the bank statements for verification purposes. To find out, you need to ask the casino.

What transaction method you're using?

I think we all-know, if you using #cryptocurrency for the transaction there no need to wait such a long time. Unless the problem are about "KYC" but if the transaction using bank transfer.

I guess depends on the bank can casino policy you're using, since we all know "Bank Statement" is contain your transaction bank history. I think is safe enough to be share.

In such cases you Need to follow their rules and their terms of subscription. There are no other ways for It. You cant go with a lawyer or a gambling associate Just because it could be just a waste of time.

I have sent my bank account statement in some cases as additional way for identification but... Of course only trusted/reputable/well know platform must receive such details.

Please provide more information about the casino, including the FAQ and any other relevant details. It's important to note that just because you trust a casino, it doesn't necessarily mean that it has a good reputation. Therefore, it's crucial to conduct thorough research and ensure that there haven't been any incidents or issues with the casino in the past that may have affected gamblers, that's really important to look at.

I have several questions, but I will wait for you to provide more information about the gambling site. In my experience, if it's a crypto-related gambling casino, withdrawing money shouldn't be an issue. However, if you used your bank account there might be some delay and you may be required to provide some of your personal documents.

I agree with you. It's a simple procedure which doesn't expose sensitive informations such as passwords. Probably they will see his name, account number, banking agency and bank name, within his history of transactions to prove the refund didn't arrive there.

The most important thing here is what casino he is talking about. If it's a reputable platform I would send all the requested data, but if it's a sketchy site I would think twice, because we never know what thieves can do with the informations we provide to them...

I personally think there's no real harm if you send your account statement for verification purpose.
The important info it contains are not sufficient for anyone to break in to your bank account.
Besides that, many other companies ask for bank account statement for verification purposes.
So we can't be denying them all because of security reasons.

I haven’t seen any online casino that will take so long before you receive your deposit, why don’t you ask why your deposit wasn’t successful and they have to refund your money back to you, also you should ask why they need your bank statement before they can make refund, refunding money shouldn’t have anything to do with your bank statement.

You said the site is a reputable site, but no site should be trusted when it comes to sharing of personal information’s, we have seen different reputable websites that have been hacked in the past and am sure more will be hacked in the future, we have seen different sites that their staffs have ended up disclosing customer’s information to hackers, so don’t trust your information with any site no matter how reputable you think it is.

They need your bank statement so that they can confirm if you deposited funds. And I don't think it will end there because they might end up contacting your bank to confirm transactions. This is one of the problems of bank transactions. Sometimes it could last up to one month to confirm problematic transactions.
It is not safe to share such sensitive documents. It could be used for evil activities. But what did the Term Of Service stipulate? If the TOS states that customers can be required to produce bank statements in issues like this, you have no option even if it invades your privacy. But if such a provision is not in the tos, you can decide not to submit the bank statement. But you have to be ready for legal action if they fail to confirm the deposit. For now, you have limited options. If you want your money back, do what they require and close the bank account.

I think it is safe to send those long as it is a reputable gamnling site you’re dealing with. Otherwise I wouldn’t really advise sending bank statements over a complete stranger. What you could do at the very least, ifi this is something that really needs to be done and something that just couldn’t wait is for you to cover any sensitive info, just leaving out the last four number to help the gambling site compare and contrast bank statements with what they have on their end. I used to have this kind of problem in the past and I asked this particular gambling site’s customer service if I could cover up the majority of my account number, leaving only thr last 4 digits so rhey can identify it was mine and they obliged.

You just have to ask basically.

Usually a business will ask for a bank statement if they need to verify your identity and the transaction you have made. It's not a big deal. But please ensure that the casino is a legal one. Since it is not a crypto casino, they must be registered and a legal entity. If not, I think it's better to contact your bank. But since 10 days have passed, the chance of getting a refund is pretty slim.

Usually businesses ask to wait for 3 days because that's the usual time for settlement. Don't know but is 10 days a normal time in your country to get bank settlement?

It is probably safe to share that information but nevertheless it is still frustrating. If you somehow manage to get your money back don't ever go near that casino again. Find another casino that don't ask private information. There are plenty of casinos out there that don't ask KYC at all. Especially those that don't have any gambling licenses are the absolute best because they don't really care where your money comes from and they won't create any fuss as long as you don't cheat.

In that case, what is the important part? Sure he can redact his address and all that, but how far can he go with this? For instance he should redact the names of people he transacts with. Let's say he has an employer, why should a casino know who sends his paychecks every month? Let's say he sends money to his family, why should the casino know the names of his relatives?
To be "safe" he should redact everything apart from his name, account number and transaction values.

You have to first know that you are not the first person that have faced this kind of situation or challenge when trying to fund their casino accounts so they can gamble, and the Casino you are playing has handled this kind of situation before. Since you have already made mention that it is a reputable casino but have refused to share their name, it is either you choose to trust them and go ahead with sending them your bank statement which I am sure that they only need to verify the statement from that day to see if the money left and not your every transaction, or decide to let the money go since you do not trust them enough.

They did asked for it? That's kind of a proof about your finances and I think that they'll relate it to your spending/deposit habits onto their own platform.

It's just gonna give them the idea on how much you've got in your bank and if you truly can gamble with that deposit you've made on them. As you've said, they're reputable so it's your trust issue whether to provide it or not.

Sometimes verifications like this are really taking long if they're not convinced with the docs that you've provided them or they need further investigation to release your funds.

Verifications can be a downright nightmare for users. Yet it is almost always mentioned in the terms and conditions, but who is going to go through it all these days? Nobody does. And if a gambling site still wants to verify via KYC, this should be handled quickly, and should certainly not take 10 days. Many casinos also use this argument to delay the payout in the hope that the gambler will continue to gamble and go wrong and lose everything in the casino. You have to be strong and at that moment no longer make any bets at all. Only then can you properly test the discretion of a casino.

If you are confident in the casino you are talking about, have not linked the address from which you deposited the casino with your other cryptocurrency addresses and are not worried about your personal information (bank statement) being processed by third parties, then you can safely send the documents.

Don't know why they'd need a bank statement. Are you sending bitcoin from or to a bank?

In a situation where a client sends cryptocurrency to a casino and withdraws only cryptocurrency back to a wallet, there's no need to ask for a bank statement. Furthermore, a person using crypto may not even have a bank account. In many countries people are unbanked. They receive cash from their employer and use it to pay their bills and buy food, but they can have a phone with a crypto wallet that can be used to gamble.

I'd tell the casino that I demand my money back and will provide the normal KYC documents like a selfie with an ID, but will not give them any bank statements because I don't own a bank account. Do that and see what they come up with :D

It's part of their TOS that they are going to need this, passport, bank statement, and all important that will confirm your identity, you sign up for this when you joined the casino and you mention that the casino is reputable I don't want to guess the name of the casino, but since you're the one playing here and you have this concern you can decide for yourself if you will go through the process everything depends on how you trust the casino and its reputation in the gambling community.

You did not post your TXTID of your deposit so we can check if your deposit really arrive, there is network congestion right now if it's not yet confirmed, ten days is good for it to get confirmed

The bank statement is obviously for the purpose of proof that you send the said amount.  Obviously they wanted to check if your bank were debited of the said amount.  If you think you can compromise your bank account data for the amount deposited and that you trust the casino then comply.  I believe you cannot blur important details here since they will know your bank account number either way.


I do not think that @OP is sending a cryptocurrency fund.  It is obvious that it is a bank transfer.

The OP should have read the terms of the casino before sending his money.
If the site is reputable and is well-known in the community, then, comply what they are asking.
Maybe, he deposited via bank transfer, hence, asking the banking statement.
If not, doubt their motive. He can drop the name of the site and maybe people from here can assist.
Is the deposit amount large enough why it was flag down, and taking too long to resolve this matter?
Hope the OP can give us more details to shed the light what is really goin on with his case.

^ Bank statements are very sensitive information and they should not be shared but there is tip and tricks that your account will not expose.
I know it is hard because I have done this before and I have no choice because I need money but when an exchange asks me for a bank statement before I will withdraw my balance, redact unnecessary information, yes that is it. If possible, redact any unnecessary information from your bank statements, such as your account number or other identifying information that is not required for verification purposes. The last one is to monitor your bank accounts regularly for any unauthorized activity and report any suspicious activity to your bank immediately.

Am just kind of surprised seeing a casino site asking for bank statements, if the OP have gone against their rules and regulations, they should have just frozen the account and ask for your kyc maybe your drivers license, or your national identity card, but am suprise they are asking for your bank statement because I don't think they are having any business with the transaction going on in your account. It's kind of suspicious and annoying, but if you really need your money back, then you don't have choice than to send it to them, or if you think the amount worth revealing your personal information, then you can do that.

Yes, it is absolutely safe to share your bank's statement of account with a third party, whether the third party be a gambling casino or an exchange, or what ever, is up to you, but the main purpose of statement of account, is that it be used for verification in times of issues like you experienced.

And point of correction., your bank's statement of account does contain your name, address, Email and maybe your phone number, but it sure does not contain all your details like you said, atleast, I am sure that you scammers can't hack into your account through your statement of account, they will need much more information about your account, and such information is not available in the statement of account.

If the casino is having difficulties verifying that you have deposited the specified amount, they may ask you for bank account transaction details so they can check. You can omit the sections of the form that ask for personal information like your address and phone number if you are unsure about providing it. Simply include the information necessary to support your deposit transaction.
Your bank information wouldn't be in danger as long as you were playing in a respectable and reliable casino, in my opinion. If there are deposit delays, some casinos genuinely ask for bank information, but I don't see anything wrong with that as banks are hard to get through screenshots.

Well  I don't know how your country's  bank and government must have designed  your country's bank statement  but I don't think the local one i know will really have any complications  except  for just verifications sake and possibly  most times, it's used to prove ones address.
And the only time I have issues or the o my set of persons I think should complain  of this are those that are too privacy conscious else, you agouodbt be scared of submitting  your bank statements  if you trust the  casino.

If you are required to give your info anyway, how would this be any different? I mean how would you even do KYC without sharing all necessary information? Bank statement or utility bill are quite common thing to share with scanned passport when you do kyc, and if it's a trusted place, i would say go for it. Nothing is 100% safe but you need to do kyc eventually anyway so just be glad that it's with a place that you trust.

It is crypto based casino? because if it is then the deposit should arrived unless you paid a fee that is small because of the current mempool clogging. If not then if it's fiat, still though how will it take this long?

Of course who will be comfortable sending their bank statement? I myself wouldn't do that. So for me it is not safe to share your bank account statement.

I try to search for casiono, but can't find anything though. Are you sure that is the name of the gambling site?

Bank statements are supposedly not for sharing, but if that's the requirement required for some important matters, it now depends on you if you want to share it. Referring specifically to an online casino, this is the first time I heard that a bank statement is the "only" required requirement for a refund procedure. There should be other requirements, not just bank statements.

And regardless of the purpose, bank statements should not be considered a requirement in the very first place.

What online casino is that? I don't see any reason why you shouldn't disclose the name to the public.

To answer your question, it depends on how far you trust that site and your eagerness to get the refund, as you said, they are reputable.

Why would anyone need to have your bank statement to prove that you haven't received anything for a refund? Wouldn't that show on their end and they are the ones that need to provide something since they're the one that needs to make it straight with you? It doesn't make sense for you to provide them with any proof of you not receiving something on your bank account. I'd say be wary of sending anything related to your finances on this casino. It's very intrusive of them to require you of this information to confirm something that they could have done on their end, honestly.

When you say reputable then you can trust them, but a bank statement is something that is very personal in fact you need a court order if anyone wants to have a peek at your bank statement, you may want to ask them for other options that can prove your identity like a passport, and if it's a Cryptocurrency transaction we can all see the transaction and its very visible on the block explorer unless you deposit with fiat,
You have to clarify this.

I assume you were making a fiat deposit through a bank to your casino account. And them asking you to provide a bank statement means you proved that you indeed made a deposit. I don't know. It should have sufficed for them to ask you to provide the receipt of that deposit.

If the deposit that you made was in crypto, I don't think they're just asking for proof of that deposit. It's possible they suspect you of something. How huge was your deposit? Maybe it has something to do with the amount.

From the casino's perspective as well is that they may be suspecting OP of doing something illegal which is why they are asking for KYC and bank statements. This must be a Bitcoin casino with a fiat option.

Of course, this may be safe since he said the casino is reputable. No matter how safe it may sound, it is also revealing his data to them which could also be leaked somewhere.

Are you talking about a cryptocurrency casino?

If it's a cryptocurrency casino I wouldn't be happy to send them my bank statemente even if they have KYC requirements in their ToS. For a reputable fiat casino, well, actually I deposit by debit card, so it doesn't make much difference. They also have to follow AML and verification procedures, so I wouldn't have a problem.

If you're making deposit through bank and the casino ask your bank statement to verify if you're genuine make a deposit toward them, why you're worried? it's different if you're making deposit through cryptocurrency and they ask your bank statement because both of them are different, but since it's a centralized exchange, all you can do is fulfill their request.

I don't see anything harm, don't need to worry if you're not don't care with KYC.

Why do they need the whole banking statement? I mean correct me if I'm wrong but you can actually use the transaction ID number or transaction tracking number to trace your deposit so they can see if it was deposited to the correct account. The casino could always verify that with the bank to check on the transaction legitimacy.
If they insists for your bank statement, you can still go ahead and provide it to them just cover all the sensitive information included in the statement. Just for you to be safe.

first of all there are a few questions I want to ask but the most important thing is the reason your deposit didn't arrive is because you didn't comply with the policies and conditions (KYC) or have done it according to the rules but the deposit still doesn't enter your casino wallet?
from your statement, you mentioned that the casino site is trusted, so is it trusted for you or is it already on this forum and has a lot of good reputation? I don't really want to know what site it is, but it would be better for you to mention the initials of the site so that someone here who has experience on the site shares stories about whether it is safe or not to provide bank transfers to gambling parties.

to be honest, while using trusted sites in this forum, I have never experienced problems such as including bank documents, etc.

Could you give more information about it? You've mentioned that the casino told you to go to your bank and ask for a bank statement, right? You should ask why on this and ask them what is the status of your withdrawal. Make them say that they already sent it to your bank, which means that is the time you'll go to the bank, but if they just said it with no reason at all, you should insist that they check where your money is and the status of it. For me, sending a bank statement is okay as long as there is a valid reason, but make sure to hide that personal information just to be safe and only show the transactions that happened in your account.

It's not easy like you said, it's true the casino can request a bank to check the transaction legitimacy, but most of crypto casinos aren't regulated with a good license, Curacao license is just a garbage license in order to convince gambler.

If the @OP said the casino is legit, I don't know why he can think it's not safe to give his KYC to them.

If it is a fiat casino, bank statement of account can be requested for to prove that you are the owner of an account and to proof if you are not lying that you did not receive fund. The site OP will be talking about would be a fiat casino. If it is a crypto casino, only what is needed is to check on the blockchain if he is telling the truth or not.

What that matters most is to never deal with fake gambling sites. If the gambling site is not fake, and if it is reputed, there is nothing bad in that.

I have sent a bank statement in the past when I tried to claim my winnings, but I must say, it's not safe to do so because it contains personal information and records of your finances. There is a risk involved in sending such documents. However, if you genuinely trust the gambling site and are desperate to receive your money, you may feel compelled to provide the requested information.

What you deposited a large enough amount that the casino asks to wait 10 business days before asking for verification?

In the case that you are experiencing, this is the first time I have heard of a casino asking for verification with a bank transfer report because usually verification is in the form of personal identification data.
In my opinion, if the casino you use is trusted and has a good reputation, it would be better to provide your bank transfer report so that the problem is resolved immediately and the money you deposited can be returned if the amount is large.
But to be honest, it's a bit odd because the casino actually asks for your bank statements.

If you are to consider your privacy it may not be necessary but yet you won't get your money recovered, but since the casino is a KYC casino enabled, they already have some aspects of your information with them, which i believe they are requesting for bank statement because they wanted to be sure that you make the deposit and only your name, email address and possibly your mobile number and contact address were all made available on the account statement you may want to present to them, which i also believe that those informations can't give them access for an entry into your account to defraud you except they have your password and other secret informations regarding the account, only your privacy that is at stake as i can see the whole scenario here and you may end up been refunded.

Identity fraud is quite big business at the moment and casino's face all sorts of dirty tactics where people abuse special offers with multiple accounts. It ruins it for everyone else so those fraudsters are the ones to blame and forced them to get stricter with verification. If you're comfortable handing over an identity document to a gambling company then you should be equally comfortable with sharing bank statements, because they will be (or should) be treated with the same level of security.

Op I have a question for you, have you completed your KYC on the casino o you're talking about? If yes then there's no issue for you because form what you're trying to say in Op you're trying not to expose your privacy but since you've already given them your personal information during the period of you completing KYC you might as well give them the bank statements for them to verify whatever it is that they want to verify.

If the money is not something that's worth risking your privacy for then you can just it go but if you're sure that nothing will happen then you send it to them.

Based on your post this was a fiat-based deposit because you are talking about a bank statement and they want to be sure that you did not receive funds they ask for your bank statement so they can follow up and make sure that you will receive your funds.
It all goes out now on how you trust the casino to show them your bank account since you mentioned that they are reputable, this is one of the benefits of using Cryptocurrency to deposit in casinos, the transaction will not take ten days to complete, and you have proof about your transaction because its visible on explorer.
I wonder why pick a fiat to deposit and do they not offer Cryptocurrency as one of the options to deposit?

Was your deposit in crypto? If not, then this topic does not really belong on a Bitcoin forum.

Whether a casino is reputable or not should not be a subjective thing. You should tell us the name of the casino.

I have not heard of any casino asking for a bank account statement for verification purposes and that seems a bit strange, to be honest.

If you give a bad actor enough information, they could easily identity theft you and take out loans in your name, and do much much more damage than you would have thought possible. You should be really careful with personal information and giving away pictures of government documents, such as ID, Passports, and so on...

Where is the casino in question registered? Did you read the terms and conditions of the casino?

We must be careful when giving out personal information. Crypto casinos require less such statements because crypto is decentralized. You should be careful, they usually ask for information like this for scams. I have never heard of such a casino before. It is not safe to share bank account statements for verification purposes. In recent times, many cases of fraud in online transactions are coming to the fore. Bank and credit card statements typically contain your name, address and account details that can be used by identity thieves to commit fraud.

Unless they also said you can hide your personal information. Was that on their statement too? Was it your first deposit on this casino, if not then you probably have deposited a huge amount that they require you to do it. Just questionable you'll be refunded yet they're asking for more verifications, I wonder what that is.

What's important depends on what the OP thinks. The casino is only concerned whether he received the money or not so what matters to them most is to match the amount and the date they sent it. Some banks only shows the last few numbers on the account so OP doesn't need to hide that. He'll probably have to show his name as well in case he already did a KYC. The description for each transaction can be hidden as well so the casino won't know where OP spends his money or where it's coming from.

It is possible that he was dealing with a fiat casino so the casino asked for a bank statement, but what is strange in my opinion is the duration of time given by the casino to resolve the problems faced by their players, the total required for players to wait until the problem is resolved by the casino is 20 days, waiting as long as it's not fun, and Op said that he was dealing with a fairly trusted casino and I'm not quite sure about that, because the duration and how the casino resolves each issue faced by its players will be one indicator of whether they can be said to be trusted.
I think Op has to be careful when he is going to give his data to the casino, everything that is quite confidential should be made invisible first, and indeed playing at a crypto casino will be better even though there is a possibility that you have to do KYC but it doesn't reach our financial data have.

Perhaps the casino means a statement made by the bank that the bank has not received any deposits or transfers from the casino so that the casino can double-check all transactions. But it's true, @OP needs to explain in more detail.

If the casino means personal data from his bank account, he should ask again if he can verify using other data such as his national ID or something else. But I am curious about the casino. Is it a fiat casino or a crypto casino? Because if it is a crypto casino, I have never come across such a case.

What website is this? And yes sharing  your bank statement is sill safe it will only show your transactions, bank account number and your name. Maybe they need to clarify if the person who has a complain and the person who will receive the money is the same. No problem with that, also if the website is well known no need to worry they know what they are doing.

Do not trust any organization. No matter how respectable you believe a casino to be, never email them your bank statement for proof.  You run the danger of having your private data stolen and exploited for illicit activity or to conduct crimes. There are several ways to verify this, therefore insist on it. Avoid running that risk.

You have probably made the deposit using your bank account and a debit or credit card and they only want to see if you have actually sent the deposit or not and I don't see anything wrong in that. They have nothing to do with your personal information and stuff, you should simply hide sensitive details and send them the details of the transaction.

It should be a matter of concern if they ask you for your personal information or bank account details, etc. Even if they inquire about your bank account number, it shouldn't be an issue since they can't do anything else apart from verifying the payment.

I don't see why it could be such a big problem for him to share his bank statement which barely give any information to them apart from the transaction history of his account which is probably what they are looking for to verify the payment. I mean, if a casino is reputable, he can share that information considering we share our identification with them when asked for KYC.

If can be an issue if the casino is new and not reputable, in that case, OP can simply ask them for another way for them to verify his identity of whatever they are trying to verify, they can also ask him about the transaction ID which might also verify the payment.

@cafter, first of all I am not aware of any legitimate casinos asked for verification for the deposit and the statement you provided 10 days required for the funds to arrive into a casino account then its a red flag just don't bother trying anything further and just expose their name so atleast anyone after you will not fall into their scam.

Asking for bank statement just at the first glance itself not seems to be right, so if they are scammers they wanted to pluck more information about you so they can keep targetting you until they drain all the money from you.

It is obviously a FIAT casino. To be honest this just another reason to move onto Bitcoin gambling. Rather to continue with FIAT casinos, they can be more annoying sometimes.
If I had to guess what it is going on I would say that OP is being subjected to a random check according to the anti money laundry policies of the casino.

It would be also possible that the casino would like to have a statement on the volume of OP and for how much time he has been a client of the bank, that would make sure he is using money he has earn in an honest way to gamble.

Yes, I also think it's a bit strange if the OP doesn't want to show that even though he has chosen to use a bank account to make a deposit and of course he already understands the risks, namely when a problem like this occurs he shouldn't feel doubtful about the casino asking for proof, even though he could. hide sensitive things not to share.

Half-half trust makes the OP not really serious in showing evidence, I'm sure the casino also feels suspicious too and doesn't trust the OP so here needs honesty from both of them, I think why are there still people who still use bank accounts to deposit at gambling whereas crypto makes things easier.  :D

Yes, OP was active again today, unfortunately, he did not come back to this topic to clarify the situation, and it's unclear why he hasn't yet provided the necessary proof to the casino. It's possible that there is a miscommunication or misunderstanding, or perhaps the player is hesitant to share the information for personal reasons. However, as mentioned earlier, requesting proof of deposit is a common practice, especially for larger transactions, and it's typically nothing to be concerned about.

In my case, I am always willing to share it if I know that they are trusted. Some legit platforms are also asking the same thing and I think once they know those details, they cannot still access our accounts if they try to, because some sensitive details are still in our possession like pin codes and passwords but if they will also ask for it, you know that it was a red flag already and we must ignore those request automatically.

Other casinos have other ways to verify their customers but what can we do if some of them only ask a bank account? Maybe we can ignore it as well and transfer to another casino which are less strict if we are not comfortable with their requests.

I also thought that its a Cryptocurrency but since OP talked about bank statements I'm sure we are talking about fiat coming from bank transfer because if it's a Cryptocurrency the transaction should be visible in the block explorer for all to see, this is the issue if OP did not publish all the complete details or information about the issue we are all left guessing and the funny thing is he is not updating this thread.
I guess he prefers to wait the 10 days period before taking action since he cannot do anything because this is what the casino asks, but its better to always use Cryptocurrency so casinos will not ask for information like this, never deposit using a bank transfer to avoid issues like this.

^This is not new when someone posts and never get back the thread that they created probably the issue has been solved on his own.
You are definitely right, why do people still want to choose their bank account linked to any gambling casino platform It is very risky being questioned. Crypto is good to use if your concern is to maintain anonymity and security, not the bank.
However, we hope OP will come back and enlighten our confusion.

From OPs description of the issue, it sure has to do with fiat, even if the casino accepts crypto, it could be one of this fiat crypto casino, op should have mentioned the name of the casino so that we can verify this..

But then, from my personal experience, it is not out of place or a scam attempt on op for the casino to ask for a statement of account from ops Bank, as long as the transaction in question involves fiat and since op claim he sent money to the casino, and as long as the casino haven't received the deposit, it is a normal process to request a statement of account from op, to verify that indeed op sent money as claimed, and also be sure that money has not returned back to ops account.

Then...
Honestly, I don't think it's your obligation to send you a proof of checking account.
In my country, in such a situation, it is the bank who needs to prove that they sent you the refund, they just need to inform the bank transfer code, so you go to the bank with that code and find out if it is valid and why it did not appear on the your account.
If there is something wrong, seek justice because if the site is reputable then they have a reputation to uphold and will try to resolve the impasse in the best possible way.

Anyway... I don't know what the website is, but I believe it could just be a "technical problem", anyway, I wouldn't send my bank statement with personal information, and also because they could easily claim that this statement has been adulterated.

You don't need to send a personal information to them maybe you can send only the proof that you deposited to that casino. You need to hide all your personal information as this day's many are getting scam because they send personal information. Please be careful about what you are doing.

The problem is that since the OP posted the thread he hasn't come back here to give clarifications. I also asked him about it in my previous post in the thread, but he hasn't clarified anything. For me there is an essential difference between a cryptocurrency casino and a fiat casino, and he could clarify that instead of having us here speculating.

I would be very careful when sharing a lot of private information with the bank. You never know how secure the casino is with keeping personal data and who can get access all these documents. First of all I would research on the internet if there have been similar issues with the casino by other users. If it's a legit casino and there are no red flags then I would double check with my bank that the issue wasn't on your end. Make sure that the bank really processed your transfer and not that there was a typo in details. In case everything is correct than it might just be lost on the casinos side and with some more information from you they should locate your funds again. Maybe you have an option to get a bank statement from the last few weeks with very limited amount of personal information on it. Otherwise I would recommend you blackout all the other transaction and all unnecessary information, only keep your name and the transfer to the casino on it.

The one who's has the biggest power is the casino, not the gambler.

If the casino ask you to give your bank statement, but you said you can't and only able to send proof of deposit, they will not listen your opinion because their decision are final. If you can't send it, then the casino don't have any problem, they can confiscate your funds and they're profit from it.

Safe? It depends on the casino that you use. Also a bank statement doesn’t contain important information that will hacked your bank account. If your meaning of safe is about your bank money, the answer is yes. The only danger here is if the casino is shady since your identity is exposed including your statement of account.


Are you aware that the information available on your bank statement is the standard details too that need on KYC? You literally just undergo KYC by sending bank statement. Also you don’t have any choice on this matter since you already made the deposit.

I think if you aren’t comfortable sending bank statement to the casino then simply  report it to your bank as refund since you didn’t get what you transferred. The casino will surely allows it since the funds didn’t arrived on your gambling account. But quicker way is to give the casino what they are asking because unlike crypto, bank transfer doesn’t have blockchain to verify all transactions. It’s a must.

You trigger the "Money laundering" matrix, when you do a deposit and then ask them to "refund" you money. I cannot see why they cannot simply look at the transaction and credit you with the amount, if it is legit?

You say it is a reputable site.... so I reckon the deposit amount was a lot of money, because the larger sites does not ask for that kind of verification for small deposits.  ???

Do you have an option other than what the casino is requesting, If you have none then you have no option but to comply or just forget about the money but I'm sure you're not going to do that, you just have to trust the casino's reputation with your information, some casinos based on their terms will ask for bank statement I don't think you are aware of it, if they don't have it on their terms you can try for other options but your chances is not good.
We all know casinos when they ask for a document it's the documents that they want nothing else.

See if you want to get your funds and they are asking for it you will have to do it but find out is the casino reputable so that no risk is there before sharing bank statements as it will also expose your bank and personal details.But if they have send funds out they might also be having information in the database so they should be clear on it.But at last it depends on you but for me it's not so much good decision.

I agree, if the casino that the OP is mentioning is legit and highly respected here in forum then I think he can send his back statement but again some details must not be seen for his privacy, if they are asking for it he has the right to complain for data privacy and also his bank account number maybe is enough if they are asking he should not give the cvv and other bank details.

That's complicated.

If they happen to ask you for your bank statement for the purpose of KYC then that's quite a heavy verification that you need to do. It's up to you, are you totally fine providing your bank statement to that reputable casino that you've said?

They may now have an idea on which bank account you are with and they can contact them anytime in the future if something goes wrong. Are your funds being hostage on that casino? You have to choose.

I agree with your statement- if the casino is reputable enough and it also has a consistent advertisement in this forum, then you are relative safe in sharing your personal information (including your bank statements) to them.

OP you mentioned about 10 banking days but you replied that it has been "10 days" since. Be reminded that 10 banking days usually mean about two (2) weeks since it excludes Saturdays and Sundays on the count.

If it has been two (2) weeks or 10 banking days and you still haven't received your deposits, then I suggest that you comply with their order or you can message/ask their representative in this forum (if they have) for general inquiries and status of your concern.

Speaking of your bank statement, which is comprised of all the transactions you have done for the month, if you go to the bank to get your statement, you can ask your bank officer to just print out the statement for the transactions you have done starting from the day you deposited at that casino to the current day, then they will need to stamp it. If you see the place where you made the transfer to your casino, you can ask them to stamp it there until the current day. You can then blank any area that contains any of your sensitive information and snap the rest of it, then send it to them, but apart from other sensitive information, I think your name should be on the account statement. Perhaps if the name on your bank statement does not match the name of your casino account, they might not attend to your issues. You said it's a reputable casino, but you need to provide the name so users here can determine the level of reputability of the casino.

It's not that simple. A casino should find a common ground with the client. It's not like they can demand a single thing and if that's not provided take your funds.

For instance, if they demand a proof of residence in the form of utility bill and you cannot give them that because you don't pay the bills in that building, it doesn't give them the right to take your money.
It's possible that a client of a crypto casino doesn't have a bank account.

You should really be at least having the time on mentioning on which site you are preferring or talking into? So that people would really be that aware that dealing up with this platform is indeed shady.

Which reputable site or company would be asking out some bank statement after you had made out some deposit?  What the heck with that 10 days of waiting? Havent they able to elaborate
on what violation you had done on why they had blocked out your deposit or didnt arrive or reflect into your account? As a player/depositor then you should really have the rights
to ask about on whats going in.

Not really just on sitting back still and waiting just because you have been told to do so. Sending out bank account statement for this matter is completely nuts.
I do believe on ID's or other documents but not this one. Would you mind on telling on how much you had deposited?

You can provide bank transaction reports, but don't provide all of your identifying information. Identity as identification for the bank register, date of birth, or parents' names may not be given. But if transaction records and bank accounts are not an obstacle when we share them with other companies.

Bank statements don't include any information that might breach your account or any related thing closed to that. If you are comfortable showing your bank transaction history to that site, it's up to you. Some centralized exchanges and stock market platforms are also asking for banking statements at some point.

But honestly, this is the first time that a gambling site requires a bank statement. I do accept and comply with sharing my bank statement for other services but for a gambling platform, I'm not comfortable with that. Since you think that the site is reputable, then it's up to you to decide on your own.

If you want to push for your refund, there's no other way but only submitting your bank statement, right?

KYC usually contains personal identification data, not bank account mutations.
Providing a bank account mutation report is quite a risky thing because it is the same as providing financial data that is owned.
Yes it is the OP's decision whether he will give it or not to be able to get back the amount that was deposited.

If I think it looks like OP is playing in a fiat casino because if using a crypto casino it's impossible the requirements regarding bank transfers are in a crypto casino we definitely deposit a sum of money with a crypto token value and send it through the exchange platform or crypto wallet that we have.

What if the personal information is cleared out first and then it is sent to the support team of that casino for verification? I don't see anything bad in that because I've also worked in support and I know it is not possible to verify payments without having enough information, so I wouldn't blame them for asking something like this.

Only in one condition I would never want to share such a thing, and that is if the platform isn't experienced or old enough to handle such stuff with care and the information you send might either be lost or misused.

Maybe his account is being tagged as a possible fraud, and the sites needs to do some investigation but I think why it took so long for the refund where in the first place the site should tell him what’s the problem in the first place. KYC should be the first one and supporting documents is next, wondering what site is this and how much money we are talking about here. OP you have to share some details here so we can give help and advises as well.

I would like to examine the situation from two perspectives. Firstly, how does he verify the bank? And secondly, does the casino have a physical location where you can go if things go wrong? Most new businesses with an online presence usually have a forum or a group where you can discuss issues related to the business, get information, and make inquiries.

It's like I smell something bad in the casino you put money into. Actually the 10 days is too long, they even beat the bank which only took 3 days if I'm not mistaken.

      If 10 days have passed and they haven't made a solution to the issue you reported to them, it seems that it is very suspicious. Why would they ask you for a bank statement when you can't even use your money to play casino games on their platform. I would understand better if you asked for kyc, so be careful no matter what, maybe later they will give you a link that you don't know is phishing.

This happens, because we go through their terms and conditions and agree for it while signing up. As said the casinos say the gamblers were the king, but the reality is against it. The casinos were the kings, because they've got control over the funds and for withdrawal and other needs we need to provide supported documents if requested. This is commonly found almost with every gambling platform when there arises a doubt on the fund deposited.

I think the OP only indicated a potential AML violation, for example the op deposited and withdrew large amounts of money consecutively. That makes sense if the casino asks for a bank statement if big money is involved, even more so for a reputable casino.
This type of verification is clearly insecure from the customer's perspective, but casinos also don't want to risk legal penalties (at least it's a last resort). Some of the suggestions above are certainly good by submitting copies of (legal) documents that only include information relevant to casino verification purposes.

The way I understand it, he played at online casino, failed to provide documents required for KYC and now the casino demands additional documents (bank statement).
In a normal situation, an online crypto casino will not want your bank statement, as you aren't withdrawing to a bank, nor playing in the casino using a fiat currency. It will only be asked when other means of verifying identity fail.

As long as we are on a legitimate and reputable gambling site, I don't believe it would be a huge deal to request an additional document to satisfy the requirement. This is typical, especially if the initial step of the KYC process was unsuccessful. I agree that the casino wouldn't do anything with our bank statements; they would simply use them as evidence in support of our claims for deposits.
Additionally, if we don't want to have the funds frozen, we have little choice than to comply with their requests. It is still a component of the KYC procedure that the majority of casinos have been applying, and based on what I have heard from players who have submitted their personal bank statements, nothing negative has ever occurred to them.

Yeah, we all know about that. That those are the things being asked in KYC but on this case, it's being asked to OP.

Only him can continue or not if he wishes to do so. It can also be a measure to know OP about money laundering matters because this seems to be gathering information about his finances that goes through his bank account.

I wonder how he responded to this.

Objectively speaking, 10 business days was a lot. they are asking business statement probably because they want to ensure if the transaction is completed with correct information.
If they are the one who mistakenly send it to wrong account, they must ensure the refund and compensation for your time. If it's your fault sending the information, well you cannot do anything about it.
Yes, bank statement which includes address and contact were mostly used as verification but your information would be at risk. Make sure that the website is truly reputable and can be trusted.

To make the decision of sending your bank statement or not to this casino that has requested it, just consider how long they have been operating. If it is a new casino requesting additional information like this about you, it can mean something is suspicious and fishy. But since it is a reputable casino, it means they are definitely old and have been operating for a number of years. I will feel more safer sending extra details of myself to a casino that has been operating for a longer time than a new casino.

In this case, it looks like he made a mistake, so the casino asked him to send us additional documents in his bank statements. We can assume that he used a bank account to withdraw his money, so the casino found a record in his account and asked him to verify it using the bank account. Or am I wrong about this?

And usually, online crypto casinos ask for our ID to verify the account, and that's enough. But perhaps, the casino can check his account through his bank statement records so that the verification process can go smoothly and he can withdraw the money.

I don't think the OP said they requested for any mean of identitification and it failed, all what he said is that he is requesting for refund and they are requesting for bank statement, I don't really know why they needed OP bank statement, have been thinking about it for long time now but i can't still point out the main reason why they need bank statement. If the OP have been gambling with fiat currency, then they might request for it if they think the account have involved in illegal activities, but if the OP is gambling with bitcoin, then I see no reason why they should request for bank statement.

if indeed the gambling site that you use has a good reputation then it doesn't matter if you share your bank statement with them but do you make withdrawals with fiat, not cryptocurrency?

In the past, when I was still using a fiat based gambling site, when I made a withdrawal, I sent my bank statement to them as proof that the withdrawal had not been received. but all want to come back to you, if you are not willing to do that then just refuse

Absolutely! In the realm of digital gambling, the path of honor and prestige is our guiding star. Casinos requesting extra paperwork? Not a challenge as imposing as a hidden fortress! Quite ordinary, especially when the initial KYC dance missed a step.

Fear not, casinos don't desire to pry into our financial chronicles. They merely require them as verification for our deposits. Akin to offering a masterfully sculpted puzzle fragment, merging flawlessly with the grand design.

To eschew unanticipated quandaries, we'd be wise to oblige. It's as if traversing a bridge towards an oasis of unhindered riches. A vital facet of the KYC ritual, and from fellow gamblers' chronicles, it's nothing short of serene navigation. Let us welcome the rite and maintain the exhilaration!

If you have tried to deposit a large amount and lost the funds and if it hurts you financially then you can take necessary steps and you can provide only the document of that transaction without giving your entire bank statement details there.  I think your risk will be reduced in this case. But if this amount is small and if you don't think that site is reputable, then skip it as it is not completely safe to share bank statement with anyone.

I think if website is reputable and have good comments around web its not that unsafe to give your bank statement. Do you anything special to worry? I mean my bank statement would only include my shopping in markets and steam purchases. lol. Nothing that much important. I see you are worried with id replication or use of your personal details to do shady things. But I think reputable websites have great customer service so no risk involved here.

No one can guarantee that the casino platform will keep your data safe and not misuse it. You know how the casino platform works and you shouldn't trust it completely. But in my opinion, he should be able to get his money back by attaching proof of his transfer and matching the data to their databases. If they find it, they can make a transfer to his account, actually it's very simple, because I used to work in the customer service department. But if this gambling platform doesn't want to make a refund and asks further questions with his sensitive data, I think he has no choice and has to include it, even though it's actually not important.

Did you use a bank account to send money to the casino?
I've used a bank statement only once in my life-to verify my Paypal account years ago(which was locked). I don't think that any sensitive data can be revealed in a bank statement. It's just your name, address and number of transactions in the past months.
However, I would be cautious about sending bank statements to online casino, which aren't legit enough.
Probably the casino is trying to verify that you have sent your own money and you are not carding.
Or maybe the casino is just using BS excuses to not pay back your money. Do you mind revealing the name of the casino?

Deposit not arriving is a big red flag as a first starting point because in most well known casinos most of the coins require just one confirmation and also most of the altcoins have very fast confirmations time while for Bitcoin you may wait a while,nevertheless not arriving means that there is something wrong on the casino side.Sending bank statement to such casino for me poses enough security risks so it is better to not do so,I would stop playing in such not well known casinos and check the Gambling section to see the ANN threads of the most reputable casinos,I am sure you won't have such problems there.

it seems this is not a problem of delayed deposits but more precisely the deposit has entered but has not been added to the gambling account. even though if you deposit using bitcoin with just 1 confirmation it can be added to the gambling account value or if you use other altcoins only a few confirmations which don't take too long.
so if the casino asks for an account transfer there are several questions, how much was deposited and whether the casino has a good reputation.

if it's only a small amount I would prefer not to send an account mutation for a small but risky amount of money. but if the amount is large and the casino is reputable, it returns to the individual gambler.

Casinos these days barely have any physical existence, and the reason for that is that they are not always so big that they should have a head office, a place where their employees work or they have all the setup, etc. Most of the platforms are just started by individuals or small groups without any physical existence.

You can barely see a casino that has a physical office or workplace where you can reach out in case things go wrong. That is the reason why it is always recommended to only use casinos that are reputable and trusted.

You will hardly see a casino with a physical office or workplace where you can reach if something goes wrong. That is why it is always advised only to use reputable and trusted casinos.

Most online casinos do not have physical casinos, so it will be difficult to find one that operates. We can only use the contacts on the website, and maybe we can call the telephone number on the site. Their employees may also be freelance employees who don't live in the same place the casino is located, making it even more difficult to find out. So if an unclear casino asks you to verify whatever the documents are, you need to suspect it. You must ask why you even asked for a bank statement as verification, if possible.

I also think 10 business days is incredibly long. It would mean like two weeks when you add weekends. Insane. Whenever I experience my deposit not going through in 1 business day I get anxious. I can't imagine waiting for straight 14 days. I also think there may be mistake from user side by deposit going through. Sometimes fiat money deposits can differ a lot. Sometimes crypto deposit may stuck if you don't know what you were doing etc. User should be aware.

The longest I have waited for pending transaction is 5 business days at most. Personally, I have never tried playing on an online platform while asking me to provide my bank statement, and for me, it seems like those things are already prying on your personal information since he had deposited using crypto and it doesn't make sense if he was asked to provide personal bank information which is already non-related to KYC. If it happens that I will encounter this kind of platform I will never go back and play on it, since it is already beyond the platform's guidelines to pry for their personal finances, and it's not as if he is greatly in debt with that platform for them to have the rights to ask about his financial information.

A bank statement is a reliable document to verify the identity of a user, and yes, you can provide a bank statement as long as the transactions on that statement are not significant enough to put your personal security at risk. Banks are obligated to keep our records confidential due to bank secrecy laws, so sharing it with a casino may pose some risks. However, as long as the transactions are not substantial enough to jeopardize your personal safety, it can be considered acceptable.

Yeah I think people aren't comfortable because they worried if something bad will happen due to their big holdings in banks. However from this case we can learn to create a new bank account on other banks, don't hold a lot money, use this bank account for gambling or other risky activities, so you will not worried in case the casino or centralized site ask your bank statements.

But still, the bank can suspect our new account, especially if we often transact by sending money to the casino site and will ask us to verify it. Maybe the bank will ask us to check whether we are responsible gamblers and really have good control of gambling.

And those who use a bank account for transactions should be careful with all the possibilities that can occur. And if they want to send a bank statement document, they must make sure the casino is really trusted in maintaining the confidentiality of the data of its members.

I would absolutely NOT ever give my bank statement out to an online casino, that is absolutely asinine. You’re write up here is a bit confusing as well. I’m assuming you sent money via your bank? This is where bitcoin has become such a big thing for online casinos. I understand there’s still often know your customer rules and verification mandates, but never ever would I do so by using a bank statement.

I want to know if this only happens to OP? Because cases like this seems rare. Usually, when it comes to KYC an ID is already enough and some selfies or I don't know, maybe the OP have done some violations or maybe the amount involved is too huge? That is why his KYC is a bit different than the rest of us. He is doubting if he will share his bank details because he is here asking for a second opinion if he will do it or not.

Casino to have contact on our banks seems a good idea because if in case we became addicted, they can order that bank to stop our withdrawals if the purpose is for gambling but not all casino will do this because it can lessen their income.

Without knowing which online gambling site the OP is referring to, it is extremely difficult to reach a conclusion. In the past, I have registered in 4-5 online casinos and only one of them asked for KYC (I chose not to undergo the process). Anyway, if the site is asking for banking documents, then they should specify that in their T&C at the time of registering to the site. I haven't heard of any of these sites asking for documents other than IDs and residential proof, but it might have happened. BTW, I am getting curious. OP hasn't posted here after the initial post. Does anyone know what happened? Has this issue been resolved?

I agree with this. You are entitled to your privacy. If they want to verify your account and wants to make sure you are really the owner of it, they can ask for KYC using identification cards, utility bills (for residential proof), and facial recognition to verify if you are really the one signing up for the account. However, sending a bank statement for verification is a little bit too much. This is a common protocol though if you want to open a bank account and to receive a debit/credit card, but it is unusual for a casino to ask since they don't need to see what's in your bank statement in the first place.

But oh well, if ever you find it sketchy, just don't push through with it. It's still better to be safe than sorry afterwards.
