Yes, there is a withdrawal fee per withdrawal transaction.


Any withdrawal transaction value of  $5 to $150, will incur a $2 withdrawal fee.


Any withdrawal transaction value of $150 upwards, will incur a $5 withdrawal fee.


If you have multiple NFTs in your account and you withdraw on the same day, your total amount of withdrawals will be calculated and you will pay one fee on the total amount of withdrawals, you will not be charged a fee on each and every NFT withdrawal.  


This will only be applied if the withdrawals of the multiple NFT/s are completed at the same time.
