What is the commission fee for KuCoin?

Excuse me, could you please clarify the commission fee structure for KuCoin? I'm interested in understanding the costs associated with trading on this platform, specifically the percentage or flat fee charged for each transaction. Is there a standard rate for all users, or does it vary based on factors such as trading volume, account type, or the specific cryptocurrency being traded? Additionally, are there any other fees I should be aware of, such as withdrawal or deposit fees? Thank you for your assistance in clarifying this matter.
