What is the maximum supply of Basic Attention Token?

In the realm of cryptocurrencies and finance, the concept of maximum supply, often referred to as 'hard cap', plays a pivotal role in determining the scarcity and potential value of a digital asset. As a curious investor, I'm particularly intrigued by the Basic Attention Token (BAT) and its underlying economics. Could you elaborate on what the maximum supply of BAT is? Understanding this figure is crucial for gauging the token's long-term potential and assessing its ability to maintain scarcity as it circulates in the market. Your insight into this matter would be greatly appreciated.
