For everyone asking about the 30k minimum withdrawal. I've asked wetsuit what he thinks and I'll let you know when he gets back to me.

My personal opinion is that it is not a problem as we also accept deposits. So if you have made 5k from the free rolls you can deposit 25k and withdraw 30k.

As we're adding more coins which are likely to be more suitable than Bitcoin for micropayments, the issue will probably go away then anyway.
