What is the fee rate for Bitget?

Could you please clarify the fee structure for transactions on Bitget? Specifically, I'm interested in knowing what the fee rate is for various types of trades, such as spot trading, futures trading, and perpetual swaps. Is there a flat fee or does it vary depending on factors like trading volume or the specific cryptocurrency being traded? Also, are there any additional fees to consider, such as withdrawal fees or deposit fees? It would be helpful to have a comprehensive understanding of the costs associated with using Bitget's platform.
