You are running into the biggest issue with crypto and gambling. People use it for two reasons, one to get funds in and out quick. Two, they want to remain anonymous for multiple reasons.
Its not a easy thing or people would have taken the bull by the horns and ran with it.
I agree with the anonymous thing here, people on bitcoin world really need to keep their identity safe, that is why they playing here but to think that they will get some profit and runaway is not something that they will do because gambling is actually not a place to get some cash in general. It is use for people to have some fun, getting profit or not is just based on your luck
