Could you please clarify what the brokerage fee structure is for transactions made on Binance? I'm particularly interested in understanding if there are any fixed fees, percentage-based fees, or any other charges that may apply to my trades. Additionally, are there any discounts or promotions available for high-volume traders or users with a certain status on the platform? Understanding the fee structure is crucial for me to make informed decisions about my investments and trading activities on Binance.
