As of now, around 19.95 million Bitcoin (BTC) have already been mined out of the maximum 21 million supply. This milestone marks a significant moment in Bitcoin’s journey, as over 95% of its total supply is now in circulation, leaving only about 2.05 million BTC left to be mined.
This development emphasizes Bitcoin’s built-in scarcity, which is one of the key factors supporting its value. Unlike traditional fiat currencies that can be printed endlessly, Bitcoin’s supply is limited by code — capped at exactly 21 million.
Why This Matters for Investors
Bitcoin’s predictable and finite supply is a major reason why it’s often referred to as “digital gold.” With such a small amount of BTC left to be mined, the competition for these remaining coins is expected to intensify among miners. This could also lead to increased transaction fees and reduced block rewards over time, especially after upcoming Bitcoin halving events, which further reduce the rate at which new BTC is introduced.
From an investor perspective, this scarcity may drive higher demand, especially as awareness of Bitcoin grows and adoption spreads across traditional finance, institutions, and global markets.

What Happens After All BTC Is Mined?
Once all 21 million Bitcoins are mined (expected around the year 2140), miners will no longer earn block rewards. Instead, they will rely solely on transaction fees for income. While that’s still more than a century away, today’s mining milestone hints at Bitcoin’s long-term trajectory toward absolute scarcity — a key part of its economic design.
With only 2.05 million BTC left to be mined, the supply shock could be more noticeable in the coming years, especially as demand continues to rise.
