What is max total supply?

Could you elaborate on the concept of "max total supply" in the context of cryptocurrencies? Is it the maximum number of coins or tokens that can ever be created within a given cryptocurrency's ecosystem? Does it remain static or can it be altered? Understanding this metric is crucial for investors to assess the scarcity and potential value of a cryptocurrency. How does it factor into the overall supply and demand dynamics? Additionally, is it set by the protocol's founders or is there a mechanism for adjustment over time? Clarifying these points would provide valuable insights for those interested in navigating the crypto markets.
