How to File a Complaint Against a Crypto Casino?

If you are reading this article, it means that something has gone wrong with a certain casino. Of course, the first reaction you might have once you are in a dispute with the casino is panic or anger. However, to make things easier for you, we have listed the exact steps that you’d need to do, and that is to collect proof before you decide to contact anyone.

This means that you would need to collect some documentation and that can involve blockchain transactions records, screenshots, even chats with customer support and game history from the moment the issue has happened. It’s obvious that this might sound like a lot but this is the exact step that will help you later on. 

What’s important to understand is that everything needs to be neat and very very organised from the start; you wouldn’t like to keep things messy. In order not to lose track later on you need to add dates to filenames, for instance 2026-02-17_BTC_Deposit.png. If you just add a random screenshot name it will just lead to confusion.

Keeping timestamps and original metadata is helpful too. Some people even create hashes of their files or timestamp evidence on-chain. You do not have to go that far, but keeping original files untouched is a very good habit.

1. Submitting Evidence

Once you have collected everything it’s essential for you to send it exactly how the casino regulator asks and this can usually mean either PNG or PDF format attachments. Using the requested formats also improves the security and credibility of your submission. You can either email them or send a compliant form. If you have too many files as proof, you can also send them everything through a secure cloud link. You would also need to ensure that your files are opening correctly as well as they are labeled very clearly. And yeah this sounds very obvious but oftentimes this very first step can get messy.

If you send physical copies, use tracked or certified mail. It creates proof that your complaint was actually received, which can be of paramount importance later.

2. Writing the Complaint

Well this part feels a bit overwhelming but to be honest, it's quite simple. What you need to do is just present the facts and you do not need any advanced legal language. You should include your account details and explain what has happened. 

Then of course attach all your evidence as mentioned before and clearly state what you want the outcome to be. We are aware that emotion can take over, but being and sounding polite while writing these emails will work much better for you.

Short Email Template Example

Subject: Complaint: Withdrawal Unpaid – Account [YourID]

Dear Support Team,

I made a withdrawal of 0.5 BTC from my account (ID: [YourID]) on 5 Mar 2026. The funds have not arrived in my wallet. I have attached the blockchain transaction and screenshots of my casino balance.

Please process my withdrawal or explain the delay within 5 business days.

Thank you,
[Your Name]

Detailed Email Template Example

Subject: URGENT: Account Frozen After Win – [YourID]

Dear Complaints Department,

My account [YourID] at [CasinoName] was locked after a legitimate win. On 10 Feb 2026 I won 1.2 BTC and requested a withdrawal of 1.0 BTC.

The account was frozen and documents were requested. I submitted my ID but the account remains locked and no funds have been paid.

Attached evidence: screenshots, blockchain records, chat logs, and ID confirmation.

I request the account to be unlocked and funds released by [date]. If unresolved, I will escalate the complaint to the regulator.

Sincerely,
[Your Name]

Short Chat Message Example

3. Timelines & Escalation

Waiting is actually the most frustrating part from all of the steps. But the reality is that casinos can usually take 1 to 4 weeks in order to respond. However, if nothing happens just send them a polite reminder and follow up.

If the issue still persists some players go even further and try payment disputes, and even police reports or small claims court. This is the last resource, however it’s important to know that not every case reaches this stage. What you need to do anyways is to keep a timeline of the emails and the follow ups, this might be helpful in the future.

5. Image & Storage Tips

This sounds more than obvious, but your screenshots should be readable, because if you submit blurry images, then an issue might occur. If your screenshots are text heavy use a PNG format and store backups of your screenshots securely.

But if you have many files it would be helpful to merge those files into 1 PDF and make things easier for reviewers. Small details like this actually help your complaint move faster.

6. Complaint Routes by Jurisdiction

Below, you can find a table showing the main authorities you can contact and what each of them can realistically do when a dispute with a crypto casino appears. This should help you quickly understand where to turn depending on the casino’s licence or lack of one.

Conclusion

Filing a complaint against a crypto casino isn’t exactly a fun activity. It involves lots of emails, waiting, follow-ups, and then more waiting. At times, this can even start to look like nothing is happening, and surprisingly, that part is even normal. And if there’s one thing that really sways the favor in your end, it’s the preparation.

The way you collect and organize all the evidence makes all the difference. Be that clear file names, clear screenshots, calm and factual communication, and no emotional messages towards the support agent. It sounds boring, but it helps a lot.

And honestly, you probably wouldn’t expect things to escalate that far, but in case they ever do, you can always check our guide about suing a crypto casino to understand what the next steps could look like.

Regulators don't ignore well-prepared complaints, and that's a fact. All dispute services depend on the evidence that you provide them with, and when everything is neatly done, you can get their attention almost immediately.

Our page takes the guesswork out of what to do next, and that alone helps more than you’d think.
