I got my Proof of source of wealth request right off the back of being accepted on the Source of wealth declaration. This was not with any pending withdrawal. My issue which I hope doesn't get flagged is that the bank statements I have sent them use a different account to the one I fund videoslots with. I guess a lot of people would be like this as many people want to keep their gambling transactions separate like me. I've shown them where the money is coming from, hope that's enough.
