WIthdrawals can be made at any time (with the exception of deposit bonuses, which may have certain restrictions). The minimum withdrawal amount is $20. The way that withdrawals are processed is that the amount you withdraw will first return to the original deposit source dating back in chronological order. Then, any additional amount will be returned via a physical check (up to 2 weeks). For example, you deposit $50 from a Visa card. With that $50 you enter a contest and win another $25. When you withdraw the full $75, $50 of it will go back to that same Visa while the other $25 will go back to either a PayPal account or as a physical check.
