what do you mean if you transfer out more than 3500 usd? You mean they ask for verification? When you say 3500 usd... u mean doing that in a single amount? If so, couldn't you just do 2k each if you want to go over that?
It's a limit of $3500. As in that's the maximum you can transfer out until you need to upload identification it's actually against the law for them to allow you to continue to use their service without identification for fraud reasons. They allow you to transfer a certain amount because it's not considered a business at that point.
