What is the total supply of Binance?

Could you please clarify the total supply of Binance, specifically referring to the Binance Coin (BNB)? Understanding the maximum amount of BNB tokens that will ever be in circulation is crucial for investors to assess the potential scarcity and value of the cryptocurrency. I'm interested in knowing if there's a predetermined cap on the total supply, and if so, what that figure is. Additionally, if the supply is not fixed and subject to change, I'd like to know the current status and any future plans regarding its adjustment. Thank you for your clarification.
