How much does BNB charge?

I'm quite curious about the fees associated with Binance Coin, or BNB. Could you please elaborate on the cost structure of this cryptocurrency? I've heard rumors that using BNB for transactions on the Binance platform can result in discounted fees, but I'd like to know the specifics. Are there any hidden costs or variable fees that I should be aware of? Also, how does BNB's fee structure compare to other major cryptocurrencies? Your insights would be greatly appreciated.
