We don't add any additional withdrawal fees as some exchanges do. .
What exchanges charge a withdrawal fee that aren't just passing the transaction fee onto the customer?
Not to nitpick, but don't your exchanges charge a 0.01 BTC withdrawal fee but not put a 0.01 BTC transaction fee on the transactions. Here is one example of a withdrawal I made and it only has the standard 0.0005 fee:
