When circulating supply reaches max supply?

Excuse me, could you please clarify what you mean by "circulating supply" and "max supply" in the context of cryptocurrency? Are you referring to the total number of coins or tokens that are currently in circulation, and the maximum number that will ever be in circulation? If so, the answer to your question really depends on the specific cryptocurrency you're asking about. Some cryptocurrencies have a finite max supply, meaning that once a certain number of coins or tokens have been mined or created, no more will ever be produced. In these cases, the circulating supply will eventually reach the max supply as more and more coins or tokens are released into the market. However, other cryptocurrencies have no maximum supply limit, meaning that new coins or tokens can be created indefinitely. In these cases, the circulating supply will never reach a maximum, as there is no upper limit to the number of coins or tokens that can be in circulation. Could you provide more context or specify which cryptocurrency you're asking about?
