As of a recent milestone, Bitcoin has now crossed the mark of approximately 19.95 million coins mined, representing over 95 % of its hard-capped total supply of 21 million. Despite this significant achievement, the remaining <5 % of issuance will be staggered over a surprisingly long timeframe—potentially more than 100 years until complete issuance is achieved.
1. The Issuance Schedule and Halving Mechanism
Bitcoin’s issuance is engineered through its underlying protocol. Every time a block is mined, a block‐reward is given to the miner; this reward is halved approximately every 210,000 blocks (or about every four years).
The most recent halving occurred on 20 April 2024, reducing the reward from 6.25 BTC to 3.125 BTC per block. According to current estimates, miners are now producing around 450 BTC per day (down from about 900 BTC/day before the halving).
Because of this geometric decline, the remaining ~1.05 million BTC will be released at a very slow pace, with the final coins projected to be mined only around the year 2140.
2. What the 95 % Milestone Means
Reaching ~95 % of the cap is both symbolically and economically significant:
-
It underscores the growing scarcity of Bitcoin, reinforcing its design as a “hard money”.
-
With issuance growth falling beneath 1 % annually after the 2024 halving, the incremental supply becomes ever more marginal.
-
For miners and network operators: as block rewards shrink, transaction fees will increasingly become the primary incentive for them.
As noted by Thomas Perfumo, economist at Kraken Global: “The predictable and diminishing issuance, combined with decentralised design, sets Bitcoin apart from traditional currencies.”
3. Long-Term Scarcity and Implications
Bitcoin’s protocol enshrines scarcity: the cap of 21 million, halving events and transparent issuance all contribute to a fixed supply growth path. This is fundamentally different from fiat currencies, which can be printed at policymakers’ discretion.
From an investment or store-of‐value vantage point:
-
Fewer new coins means, in principle, less upward pressure on supply, which could support value if demand continues.
-
However, scarcity alone does not guarantee price appreciation—demand, utility, macro factors and regulatory environment all matter.
-
With the remaining ~1.05 million coins to be mined over the next ~115 years, we face one of the slowest issuance curves arguably in asset history.
4. Risks, Considerations & What To Watch
While the scarcity narrative is strong, several caveats deserve consideration:
-
Not all of the existing ~19.95 million coins are necessarily available for circulation: some were lost (e.g., lost private keys), and some outputs (like the genesis block reward) remain unspendable (~230 BTC)
-
Mining economics: as block rewards shrink, miners become more dependent on transaction fees; if fee revenue or block‐reward incentives decline significantly, network dynamics could shift.
-
Market and macro factors: regulatory changes, technological shifts, competition from other digital assets or protocols, and broader economic conditions could still impact Bitcoin’s role and valuation.
-
The long horizon to full issuance (2140) is largely symbolic—but it embeds a commitment to scarcity that few other assets can match.
5. Conclusion
Bitcoin’s crossing of the 95 % issuance threshold is a milestone worth noting: it highlights the success of a pre-programmed, transparent issuance schedule and emphasises the ethos of scarce digital money. Yet, the path ahead—until full issuance—spans decades, reminding us that Bitcoin’s design is for the long term. Whether you view it as digital gold, an alternative monetary system, or a speculative asset, its scarcity mechanism is now entering a mature phase.
Still, scarcity is just one piece of the puzzle. For Bitcoin’s value and utility to continue unfolding, factors like adoption, governance, regulatory clarity, infrastructure robustness and macro context will remain vital.
