You won't see a change to your BTC balance until payouts happen, once a day at GMT 04:00:00. Normally you'd have an "Estimated Un-Exchanged" and "Estimated Exchagned" value that grows and adjusts throughout the day, those are currently disabled, and being worked on. If you don't have a balance *after* payout time, its something to be concerned about, and let support know.
