Yabby Casino - Player's withdrawal request is denied due to unconfirmed deposit.

I have been a customer for several years at Yabby Casino and have never had an issue before today. Last night I made a bitcoin deposit of $39 and didn’t use any bonuses. At Yabby, as soon as you send funds from your BTC wallet your casino account gets credited. Sounds great, and that’s what happened. After about two hours of playing, I ran my balance up to a little of $1k and submitted a withdrawal request like I’ve done many times in the past. I got an email this morning that said it was denied because the deposit wasn’t confirmed. I went into my wallet and increased the transaction fee and then the deposit fully confirmed about an hour later. I then requested another withdrawal only to be denied again, but this time the reason was I won money on an unconfirmed deposit. This is unacceptable to me and they won’t do anything about it.

Dear Hcolwick,

Thank you very much for submitting this complaint. I'm sorry to hear about the problem you're experiencing. Please allow me to ask you a few questions to clarify your situation.

Am I correct in understanding that your most recent withdrawal request was declined only after your deposit was confirmed as successful?

Have you contacted the casino customer support regarding the issue with your withdrawal?

Could you please send me a screenshot of your deposit history and your withdrawal history from your casino profile?

I hope we will be able to help you resolve this issue as soon as possible. Thank you in advance for your reply.

Best regards

Dear Hcolwick,

We are extending the timer by 7 days. Please, be aware that in case you fail to respond in the given time frame or don’t require any further assistance, we will reject the complaint.

Yes, I made a normal crypto deposit like I always do, and once I sent the funds from my BTC wallet my casino account was credited with the deposit. So I start playing and I win $1k fairly quickly and request a withdrawal. They declined my withdrawal initially and the reason was that was deposit wasn’t confirmed yet. I go and look in my BTC wallet and see that it’s still pending so I increase the transaction fee and the transaction is fully confirmed about an hour later. After it was successfully confirmed I requested another withdrawal, and this time it got declined because they

said I used "illegal funds" because the deposit wasn’t confirmed. Not sure how that can be the case when they gave me the instant credit to play with. I also wasn’t playing on any bonus so it’s pretty clear cut and very frustrating. They are just looking for a loophole not to pay me.

Any update on the casino stealing my money?

Thank you very much, Hcolwick, for providing all the necessary information. I will now transfer your complaint to my colleague Michal (michal.k@casino.guru) who will be at your assistance. I wish you the best of luck and hope to see your problem being resolved to your satisfaction in the near future.

Hello Hcolwick,

I'm Michal, and I have taken over your complaint. I have reviewed this case, and I understand your perspective. Please forward me a statement from your crypto wallet where the disputed deposit is clearly visible and confirmed in the blockchain before you acquire your winnings at michal.k@casino.guru

I will contact the casino to shed more light on this matter.

We would like to invite Yabby Casino to join the conversation.

Dear Yabby Casino,

I would appreciate your assistance in clarifying the issue. Why was the player's deposit reflected in their casino account when, as you later stated, the deposit was not processed successfully on the blockchain? How should the player know that this occurred?

I sent an email with the documentation you requested

Dear Michal and Hcolwick,

Thank you for reaching out. We appreciate the opportunity to clarify this matter.

At Yabby Casino, crypto deposits are processed instantly once they appear on the blockchain, even before receiving network confirmations. This allows players to start playing without delays. However, because transactions can be seen before they are confirmed, there is a potential risk of exploitation, where a player could attempt to reverse or invalidate their deposit before it gets confirmed.

In this case, our system detected that the deposit made by Hcolwick was a double-spend transaction. This means that the original transaction, which was credited to the player's account, was later replaced by another transaction using the same inputs, making the initial deposit invalid. As a result, any winnings generated from this deposit had to be removed.

@Hcolwick, you mentioned that you only increased the transaction fee. However, if this was done through a standard Replace-by-Fee (RBF) method, the transaction would have retained the same transaction hash ID. In this case, the confirmed transaction had a different hash ID, indicating that a new transaction was broadcast instead, which is a clear sign of a double-spend attempt.

Additionally, we noticed that you later made a separate deposit to the same address, which was processed correctly under a new transaction hash. That deposit was credited to your account only after the winnings from the invalid deposit were removed, and you were able to successfully withdraw the funds from that valid deposit. This further confirms that the initial deposit was not valid and did not remain on the blockchain.

@Michal, to validate all of this, we have sent proof of the double-spend attempt to you via email, including the relevant blockchain transaction details. We encourage you to review this information.

We understand that players may not always be aware of how blockchain transactions work, but we must ensure that only valid deposits are used for gameplay. Our Casino operates under the principle that players must use legal funds, and a deposit that is later invalidated on the blockchain does not meet this requirement.

If further clarification is needed, we are happy to review any additional transaction details provided by the player.

Best Regards,

James Peterson

Literally the only thing I did in my bitcoin wallet was go into the pending transaction and click on the button to increase the transaction fee then it confirmed an hour later. It was not a separate transaction and there is nothing I could have done differently. There was nothing nefarious done here as you can tell from my transaction history for multiple years.

If you look at the withdrawal history, the first time this $1000 withdrawal got denied the reason was the deposit was unconfirmed, which I completely understand. Which is why I then went to increase the transaction fee. It wasn’t until after that that the new reason was it was declined for "double spend"

Thank you for your email with the evidence, James / Yabby Casino.

Dear Hcolwick,

After thoroughly reviewing all the information and evidence related to your case, I regret to inform you that I cannot take it further.

It has been verified on the blockchain that there are indeed two transactions, each with distinct transaction hashes, as noted by the casino team. Unfortunately, the evidence indicates that this situation falls under a double-spend case, as explained by the casino team above. I understand this may not be the outcome you were hoping for, but after careful consideration, we must uphold the casino’s decision in this case.

While I highly recommend that the casino enhance its system to ensure multiple confirmations on the blockchain for transactions before the funds are credited to a player's account. This would help prevent similar issues in the future; however, the casino team has acted in accordance with the terms you accepted when you created your account.

You are certainly entitled to disagree with this conclusion and can reach out to the casino licensing authority if you feel justified in your position, but we are unable to offer any additional assistance regarding this issue. Sorry, we were not able to help you with this one, but feel free to reach out to us again should you encounter any other issues with this or another casino. We will try our best to assist.

Best regards,

Michal
