How many Monero are left?

Could you please elaborate on the matter of Monero's remaining supply? I'm curious to know how many Monero coins are still available and circulating in the market. Given the nature of cryptocurrency and its finite supply, it's essential to understand the current status of Monero's availability. Is there a specific number or estimation that can be provided? I'm also interested in knowing if there are any factors that could potentially affect this figure in the future. Could you please shed some light on this matter?
