Many posters have already made some great suggestions, but I would like to add by saying that your questions are very vague. You didn't specify if you are comfortable submitting your KYC at different stages or not?
It is no longer possible to talk about reliable casinos with a good reputation in the market without the casino imposing KYC identity verification procedures. This means that any user must be prepared to submit to these procedures at any time, especially when it comes to making successive withdrawals or withdrawing a large amount of winnings.
The same applies even to new casinos that usually do not impose these procedures in the period following the launch stage and may not mention this in the terms of use that the user agrees to when registering. It is certain that they will impose these procedures later after they modify the terms of use. This has become known and repeated.
Users who take into account the principle of privacy have limited options with a small number of decentralized casinos available that do not have all the features that we find in centralized casinos.
On this basis, the most important condition that the user must ensure is that the casino has a valid activity license because this is more guarantee of rights in the event of any problem.
