I had no idea that crypto casinos could ask for these documents. They look like a bank asking you for proof of funds. I knew they are increasingly implementing KYC and AML but not to this extent. The downside is that they have your current funds at Stake locked. Are we talking about a lot of money?

I see that the article where you specify the documents you accept was written a week ago. I don't know if they started implementing it a week ago, but as you say, it doesn't include the activities you mention, and it doesn't include a very common activity in the forum: participating in signature campaigns.

I hope this doesn't go mainstream because a lot of people are going to be left with their funds locked, and also crypto casinos are going to lose a lot of business.

To bet on from now on, the solution is easy, go to one of the few remaining casinos that still don't ask for KYC or all these documents:
