How many ADA Cardano are left?

Could you please enlighten me on a matter of cryptocurrency? I'm particularly interested in understanding the availability of Cardano's native token, the ADA. Could you possibly provide me with an estimate of how many ADA Cardano are currently in circulation? Also, if you have any insights into the future supply and demand trends for ADA, that would be incredibly helpful. Is there a maximum supply cap for Cardano, and if so, what is it? Additionally, how does the current supply compare to the initial supply of ADA when it was first launched? I'm eager to learn more about this fascinating aspect of the crypto world. Thank you in advance for your assistance.
