I'm curious about the intricacies of the Trac coin economy. Could you elaborate on the total supply of Trac coins? Is it a finite number, or does it have the potential to increase over time? Understanding the total supply is crucial in assessing the long-term viability and potential of the coin, as well as its impact on market dynamics. So, I'd appreciate a concise yet comprehensive answer that sheds light on this crucial aspect of the Trac coin ecosystem.
