Bitcoin continues to gain traction due to its decentralized nature and potential for long-term value appreciation. With over 19 million BTC already mined and the next halving event less than a year away, a critical question arises: What happens when all 21 million bitcoins are mined?
Key Takeaways
- Approximately 900 BTC are mined daily, with 92.358% already in circulation.
- The 2024 Bitcoin halving will reduce block rewards from 6.25 BTC to 3.125 BTC.
- Stakeholders like miners, investors, and governments will face significant impacts once the supply cap is reached.
How Many Bitcoins Remain to Be Mined?
As of June 2023, 19.402 million BTC are in circulation, leaving just 1.59 million BTC left to mine. At the current rate (~900 BTC/day), the last bitcoin is projected to be mined by 2078.
🔍 Note: "Lost" bitcoins refer to those permanently inaccessible due to misplaced private keys, estimated at 20% of the total supply (~$140 billion worth).
Bitcoin Halving Explained
Halving events occur every 210,000 blocks (~4 years), reducing block rewards by 50%:
| Year | Block Reward |
|------------|--------------|
| 2009 | 50 BTC |
| 2012 | 25 BTC |
| 2016 | 12.5 BTC |
| 2020 | 6.25 BTC |
| 2024 (est.)| 3.125 BTC |
Why Does Bitcoin Have a Supply Cap?
Satoshi Nakamoto set the 21 million BTC limit to:
- Prevent inflation.
- Stabilize prices by controlling supply.
- Gradually release BTC via mining (fixed annual supply until the cap is reached).
⚙️ Mining Mechanism: The network adjusts difficulty every 2,016 blocks (~2 weeks) to maintain a 10-minute block time.
Can the Bitcoin Supply Limit Be Changed?
Technically, yes—but it’s highly unlikely. Altering the cap would require:
- Consensus among developers, miners, and nodes.
- A hard fork (e.g., Bitcoin Cash split).

Implications for Stakeholders
Miners
Post-21 million, miners will rely solely on transaction fees (currently 6% of revenue). Challenges include:
- Rising operational costs vs. diminishing rewards.
- Potential "death spiral" if mining becomes unprofitable.
Retail Investors & HODLers
- Scarcity-driven price surges may incentivize holding BTC as a store of value.
- Reduced circulating supply could amplify volatility.
Institutions
Companies like Tesla and Goldman Sachs view BTC as "digital gold"—a hedge against inflation. Adoption may accelerate as the supply cap nears.
FAQs
❓ Will Bitcoin’s price crash after all are mined?
Unlikely. Scarcity and demand dynamics could drive prices higher.
❓ How will miners stay profitable?
Higher transaction fees or cost-efficient technologies (e.g., renewable energy).
❓ Could Bitcoin’s code be updated to increase supply?
Possible, but consensus is nearly impossible given Bitcoin’s decentralized ethos.

Final Thoughts
The 21 million BTC cap ensures scarcity, but its long-term impact hinges on adoption, technological adaptations, and market behavior. Stakeholders must prepare for a fee-driven economy post-mining.
