What is the fee for KuCoin?

Excuse me, could you please clarify what the fee structure is for KuCoin? I'm particularly interested in understanding whether there are any trading fees, deposit fees, withdrawal fees, or any other associated costs that I should be aware of when using this platform. It would be greatly appreciated if you could provide a comprehensive overview of the fees, including any discounts or promotions that may be available to users. Thank you in advance for your assistance.
