Bitcoin has a crucial inherent characteristic: its total supply is capped at a maximum of 21 million coins. This limit is part of Bitcoin's design, written into the system's core code, and cannot be arbitrarily changed by anyone. So why 21 million, and not more or less?

Satoshi Nakamoto's purpose in this design was to make Bitcoin scarce, much like gold. In traditional financial systems, governments can increase the money supply by printing more currency, which leads to devaluation. In contrast, Bitcoin's supply is fixed and predictable, giving people more confidence to hold it. This design has also led many to view Bitcoin as 'digital gold'.

Specifically, new bitcoins are issued through a process called 'mining'. A new block is generated approximately every 10 minutes, and miners receive a certain number of new bitcoins as a reward. This reward is halved roughly every four years, starting at 50 coins, then dropping to 25, 12.5, and so on. Once the last bitcoin is 'mined', the total supply will reach its cap of 21 million and will not increase further.

This fixed cap ensures Bitcoin's scarcity and makes it a digital asset resistant to inflation. However, understanding how Bitcoin works is just the first step. If you are interested in this new type of asset, remember to learn about and engage with it through legal and secure channels to safely participate in this innovative world.
