Our system makes bitcoin withdrawals automatically once per day, but only if your bitcoin address has been specified and your balance is greater than the configurable withdrawal threshold which is 0.002 BTC (200 000 satoshi) by default. The minimum withdrawal threshold is 0.001 BTC (100 000 satoshi).
If you see that our system has already made a withdrawal, but your wallet hasn't received the money then you need to wait. It may take a significant amount of time, hours or even days.
You can also opt in for FaucetSystem withdrawals, which are nearly instantaneous and don't require a withdrawal threshold.
