What is KuCoin transaction fee?

I'm curious about the specifics of KuCoin's transaction fees. Could you please elaborate on what they entail and how they compare to other cryptocurrency exchanges? Do the fees vary depending on the type of transaction, such as trading, depositing, or withdrawing? Is there a flat rate or is it a percentage-based fee? Additionally, are there any incentives or discounts available for frequent traders or users with high trading volumes? Understanding the cost structure is crucial for me to decide if KuCoin is the right platform for my cryptocurrency trading needs.
