This will be happen when you come on the right time. Now, we can withdraw peercoin only. And the previous day, I'm late. Can't withdraw all coins. Although available coins listed to be withdraw, still found "insufficient balance". When you come 24 hours after refilled, you will find "insufficient balance" message. Unfortunately, I always late. Not sure I can withdraw all balance when I come at the right time because my balance more than the limit, even with exchange feature usage.
