The total supply of Bitcoin is steadily nearing 20 million coins, with the current count bringing us closer to this milestone. However, it is important to note that the last million Bitcoins will not be mined quickly; rather, it is projected to take an astonishing 114 years to fully extract the final portion of the supply from the network. This extended timeline underscores the deflationary nature of Bitcoin and highlights the gradual process of mining, which is designed to slow down as the total supply approaches its cap of 21 million coins.
