If you're only win some amount like x5 or x10 from your deposit amount and the amount is less than <$1000 it's only tiny amount for the casinos. Of course there's no reason why they should scam you for tiny amount while they can scam more money than that. 1xbit is selective scammer, if you only deposit for $100-$500 and win big amount money e.g above 1 Bitcoin, and they let you withdraw... post it here.
This won't necessarily prove that they aren't scammers and are completely legit or anything. As you said, they selectively scam their customers.
They could process withdrawals ranging from hundreds to thousands of dollars successfully without any issues while scamming other gamblers simultaneously which is pretty smart if you think about it.
I can see that you really care about convincing everyone to your opinion. But the fact is that this is still just your theory that you have come up with and cannot be supported by any argument.
No, is not just a theory. That's literally what scam casinos do. Really all types of scammers do it. Being a successful scammer is a balancing act, keeping your reputation as clean as possible while also stealing as much money. If you steal too much too fast, your future profit takes a hit. It's clearly what 1xbit is doing. (No doubt they wouldn't be able to steal as much if it weren't for shills like you).
I've seen it over and over, and it makes sense: they process most withdraws and look for opportunities to scam larger amounts while pointing to all those withdraws you processed as proof you aren't a thief. Players that seem less credible or demonstrate a lack of communication skills make for better targets than someone that's articulate or is known to be active and vocal in the gambling community. I doubt they would ever scam one of their shills unless they were very desperate or it was a ton of money.
This theory may make sense if the amounts you are talking about were significant. Are you telling me that 1xbit only selects users who deposit below $1000? Such an accusation against such a large casino like 1xbit is pointless! These amounts do not cover even part of the costs of a signature campaign.. Come on!
