What is the max supply of icon ICX?

Could you please elaborate on the maximum supply of the ICON ICX token? As a cryptocurrency enthusiast and investor, I'm curious to understand the limitations, if any, on the total number of ICX tokens that can be issued. Understanding the supply cap is crucial for evaluating the potential long-term value and stability of the token. Is there a fixed maximum supply, or does the protocol allow for a gradual increase over time? Additionally, what are the implications of this maximum supply on the token's economics and market dynamics? Thank you for your insights.
