The total number of Bitcoins is capped at 21 million. This limit is a core feature, ensuring scarcity, similar to precious metals like gold.

Circulating Supply
While 21 million is the maximum, not all Bitcoins have been mined. The circulating supply refers to the number of Bitcoins that have already been mined and are available.
Mining and Creation
Bitcoins are created through a process called mining, where miners validate transactions and secure the network using computational power.
Distribution
Ownership of Bitcoin is becoming more evenly distributed, with the top addresses holding a smaller percentage of the total supply than in the past.
Lost Bitcoins
A portion of the mined Bitcoins are considered lost due to forgotten private keys or other reasons, effectively reducing the available supply.
This fixed supply differentiates Bitcoin from traditional currencies.
The limited supply is built into the code.
The circulating supply is constantly changing.
Bitcoin emerged after the 2008 crisis.

The Significance of Scarcity
This pre-determined scarcity is a key factor in Bitcoin’s value proposition. Unlike fiat currencies, which can be printed at will by central banks, Bitcoin’s supply is fixed, potentially making it a hedge against inflation.
The Future of Bitcoin Supply
The rate at which new Bitcoins are mined decreases over time, a process known as “halving.” This ensures that the remaining Bitcoins will be mined gradually, with the last Bitcoin projected to be mined sometime around the year 2140.
What About Lost Bitcoins?
While the protocol dictates a maximum of 21 million, a significant portion of mined Bitcoins are estimated to be lost forever due to forgotten private keys or inaccessible wallets. This effectively reduces the available supply, potentially increasing the value of the remaining coins.
Monitoring the Supply
Various online resources track the circulating supply of Bitcoin in real-time. This data provides transparency and allows users to monitor the progress of Bitcoin mining and the overall availability of the cryptocurrency.
The limited supply of Bitcoin is a fundamental aspect of its design and a key driver of its perceived value. Understanding the dynamics of Bitcoin mining, circulating supply, and potential losses is crucial for anyone interested in this digital asset.
