What is the maximum supply of 1000SATS?

Could you please elaborate on the concept of "maximum supply" when referring to 1000SATS? I'm interested in understanding how this figure is determined and what implications it has for the overall cryptocurrency ecosystem. Also, could you explain how this maximum supply affects the value and trading of SATS, and whether there are any factors that could potentially alter this supply in the future? Additionally, it would be helpful to know if there are any similarities or differences between the supply mechanism of SATS and other cryptocurrencies. Thank you for your insights.
