Me too am thinking of just giving up with the KYC.
I have no issue with that as I have done it with other bookies but what they request is simply unreal

That is not true. They do not ask you to provide all those documents. These are just examples they suggested that you can attach as evidence for "source of funds". Of course, you won't need to submit all of that. That would be silly.

Let's talk about this after hitting a huge balance, they will definitely ask for documents in order to verify the account then let you withdraw your winnings.
Check some related gambling boards and tons of accusations there, many users got emails to verify accounts due to timezone difference on browser vs IP location.
You are missing the point. Please read again what nakisama wrote
here and what I replied. Don't just write nonsense like he does.
"Source of funds" is a pretty standard requirement in KYC verification (that doesn't mean I agree with it) and what they listed are acceptable documents for source of funds. This does not mean that ALL these documents are needed.
I think you didn't quite understand what @salama meant.
He meant that at the moment these documents are not required, but they can be when someone manages to win a large amount. He even gave an example that some casinos require documents to prove that you were really in the time zone according to your IP login time.
