How Many Bitcoins Are Left? (2026)

Summary

As of early 2026, approximately 19.95 million of Bitcoin's 21 million total supply have been mined. That leaves roughly 1.05 million bitcoins left to create, less than 5% of the maximum supply. Due to Bitcoin's halving schedule, those remaining coins will be released gradually over the next century, with the final bitcoin expected around 2140.

Bitcoin Supply Explained

Bitcoin has grown from an experimental digital currency into one of the most widely held financial assets on the planet. Institutions allocate to it. Governments regulate it. Public companies carry it on their balance sheets. And millions of individual investors treat it as a long-term store of value.

But the feature that underpins all of that interest isn't price performance or brand recognition. It's scarcity.

Unlike fiat currencies that central banks can expand at will, Bitcoin has a hard cap of 21 million coins written directly into its protocol. No government can raise that ceiling. No committee can vote to print more. That fixed supply is one of the core reasons Bitcoin is often compared to gold, and why the question of remaining supply matters so much to anyone evaluating it as a long-term investment.

How Many Bitcoins Are Left to Mine in 2026?

As of early 2026, approximately 19.95 million bitcoins have been mined. That leaves roughly 1.05 million bitcoins still to be created before the 21 million maximum supply is reached, less than 5% of the total.

The milestone of 20 million mined BTC is expected around March 2026, which means over 95% of all Bitcoin that will ever exist is already in circulation.

Those remaining coins will not appear all at once. Bitcoin’s code releases new supply on a fixed, decelerating schedule. The final bitcoin is projected to be mined around the year 2140, more than a century from now.

This slow, predictable release schedule is what separates Bitcoin from every government-issued currency in existence.

How Many Bitcoins Are Mined Per Day?

At the current block reward of 3.125 BTC per block, and with one block mined roughly every 10 minutes, about 450 new bitcoins are created each day. That translates to approximately 164,000 BTC per year.

After the next halving, expected in April 2028, daily issuance will drop to approximately 225 BTC per day, or about 82,000 per year.

Period	Block Reward	Daily Issuance	Annual Issuance (approx.)
2024–2028	3.125 BTC	~450 BTC	~164,000 BTC
2028–2032	1.5625 BTC	~225 BTC	~82,000 BTC
2032–2036	0.78125 BTC	~112.5 BTC	~41,000 BTC

What Percentage of Bitcoin Has Been Mined?

About 95% of all Bitcoin has already been mined. With roughly 19.95 million of the 21 million total supply in circulation, the remaining 5% will take over 100 years to produce, a direct result of the halving mechanism that cuts new issuance in half every four years.

Bitcoin’s supply curve is heavily front-loaded. The first 50% was mined within just four years of launch. The last 5% will take more than a century.

How Does Bitcoin Mining Work?

Bitcoin mining is the process that both creates new bitcoins and secures the network.

Bitcoin runs on a Proof of Work system. Miners deploy specialized hardware (known as ASICs) to solve complex mathematical puzzles. The first miner to solve the puzzle earns the right to add the next block of transactions to the blockchain, Bitcoin’s public ledger, and receives newly created bitcoins as compensation.

Mining serves two functions simultaneously: it validates and confirms every Bitcoin transaction, and it controls how new supply enters circulation. Because the process requires real energy and significant computing power, tampering with past transactions would demand impractical resources, which is what makes the network secure.

The critical design choice is that mining doesn’t just secure Bitcoin. It governs exactly how and when new coins are released.

How the Bitcoin Halving Controls Supply

When Bitcoin launched in 2009, miners earned 50 BTC per block. That reward is cut in half every 210,000 blocks, roughly every four years, in an event called the Bitcoin halving.

Here’s how the block reward has decreased over time:

Year	Event	Block Reward
2009	Bitcoin launches	50 BTC
2012	First halving	25 BTC
2016	Second halving	12.5 BTC
2020	Third halving	6.25 BTC
2024	Fourth halving	3.125 BTC
2028 (est.)	Fifth halving	1.5625 BTC

Each halving reduces the rate of new supply entering the market. Bitcoin’s current annual inflation rate sits around 0.83%, already lower than gold’s historical supply growth rate of approximately 1.6% per year. After the 2028 halving, Bitcoin’s inflation rate will drop to roughly 0.4%.

This is sometimes called “programmed scarcity.” Unlike gold, where new deposits can be discovered and production scaled up, Bitcoin’s issuance schedule is entirely transparent and mathematically fixed.

When Is the Next Bitcoin Halving?

The next Bitcoin halving is expected in April 2028 at block height 1,050,000. When it arrives, the block reward will drop from 3.125 BTC to 1.5625 BTC, cutting daily issuance from approximately 450 BTC to approximately 225 BTC.

Historically, Bitcoin’s price has experienced significant volatility and increased public attention in the 12–18 months following each halving. The 2024 halving was notable because Bitcoin reached new all-time highs before the event, driven in part by the approval of spot Bitcoin ETFs in the United States in January 2024.

While past performance does not guarantee future results, halving events remain among the most closely watched dates on the crypto calendar because of their direct impact on supply.

Why Is Bitcoin Limited to 21 Million?

Bitcoin’s creator, Satoshi Nakamoto, hard-coded the 21 million coin limit into the protocol. The design mirrors the scarcity properties of precious metals: a finite resource that becomes harder to extract over time.

This cap creates a monetary framework fundamentally different from fiat currency. There is no mechanism for expanding Bitcoin’s supply in response to economic conditions, political pressure, or fiscal policy. The total amount is fixed, the release schedule is public, and both are enforced by code rather than institutions.

For investors, this means Bitcoin cannot be diluted. The supply side of the equation is locked. Price movements over time are driven almost entirely by demand.

How Many Bitcoins Are Lost Forever?

Not every mined bitcoin is still accessible. Analysts estimate that between 3 and 4 million BTC are permanently lost, locked in wallets where the private keys have been forgotten, stored on hard drives that were discarded, or held by early users who passed away without sharing access.

One frequently cited case involves a British man who accidentally threw away a hard drive containing roughly 8,000 BTC, worth hundreds of millions of dollars at today’s prices.

If these estimates are accurate, the effective circulating supply of Bitcoin is closer to 16 million than 19.95 million. That makes Bitcoin’s real-world scarcity significantly greater than what the raw mining numbers suggest.

Unlike a bank account, lost bitcoin cannot be recovered, reset, or reissued. Once access to a wallet’s private key is gone, those coins are permanently removed from circulation.

How Many Bitcoins Does Satoshi Nakamoto Own?

Satoshi Nakamoto, Bitcoin’s pseudonymous creator, is estimated to hold approximately 1 to 1.1 million BTC across thousands of wallet addresses. These coins were mined during Bitcoin’s earliest months in 2009 and 2010.

None of them have ever moved.

Whether Satoshi is a single person or a group, whether they’re alive or deceased, remains unknown. What is known is that these coins have sat untouched for over 15 years. Many analysts consider them effectively removed from the circulating supply, which further tightens Bitcoin’s practical scarcity.

What Happens When All 21 Million Bitcoins Are Mined?

Once all 21 million bitcoins have been mined, projected around the year 2140, miners will no longer receive block rewards of newly created BTC. Instead, they’ll be compensated entirely through transaction fees paid by users.

Today, miners already earn from two sources: block rewards and transaction fees. The transition to a fee-only model is gradual and has been underway since Bitcoin’s launch.

For this model to sustain network security long-term, Bitcoin must continue processing a meaningful volume of transactions. If usage and adoption remain strong, transaction fees should provide sufficient incentive for miners to keep the network running.

This isn’t a cliff. It’s a 114-year transition that’s already well underway.

Can the 21 Million Bitcoin Limit Be Changed?

Technically, Bitcoin is open-source software, and any change to the protocol requires consensus among its global network of node operators and miners. Theoretically, someone could propose removing the 21 million cap.

In practice, this is extraordinarily unlikely to happen. The fixed supply is one of Bitcoin’s foundational value propositions. Node operators, who validate the rules of the network, would have to voluntarily agree to a change that would dilute their own holdings. There is no realistic economic incentive for a majority of participants to support that kind of modification.

Every previous attempt to alter Bitcoin’s core properties has resulted in a separate fork (like Bitcoin Cash), not a change to Bitcoin itself.

Why Bitcoin’s Supply Schedule Matters to Investors

Understanding how many bitcoins are left provides insight into Bitcoin’s long-term monetary structure and why it attracts a specific kind of investor.

Bitcoin doesn’t generate earnings like a stock. It doesn’t pay interest like a bond. Its investment thesis is built on scarcity, security, decentralization, and global accessibility.

As issuance continues to slow through future halvings, new supply becomes a smaller factor relative to total circulating supply. Price movements are increasingly driven by demand. For long-term investors, this predictable supply trajectory offers something uncommon in financial markets: certainty about one half of the supply-and-demand equation.

Bitcoin’s inflation rate is already lower than gold’s. After 2028, it will be roughly one-quarter of gold’s.

Frequently Asked Questions

How many bitcoins are left to mine?

As of early 2026, approximately 1.05 million bitcoins remain to be mined out of the 21 million maximum supply. Over 95% of all Bitcoin has already been created.

How many bitcoins are in circulation?

Roughly 19.95 million bitcoins have been mined. However, an estimated 3 to 4 million BTC are permanently lost, putting the effective circulating supply closer to 16 million.

How many bitcoins are mined each day?

At the current block reward of 3.125 BTC and an average of 144 blocks per day, approximately 450 new bitcoins are mined daily. That number will drop to about 225 per day after the 2028 halving.

When will the last bitcoin be mined?

The final bitcoin is projected to be mined around the year 2140, when the block reward will have been halved so many times that it effectively reaches zero.

What happens after all bitcoins are mined?

Miners will rely entirely on transaction fees to sustain their operations and secure the network. This transition from block rewards to fee-based compensation is already underway and will happen gradually over the next century.

How many bitcoins does Satoshi Nakamoto have?

Estimates place Satoshi’s holdings at approximately 1 to 1.1 million BTC, mined in 2009–2010. These coins have never been moved and are widely considered removed from the active supply.

Why can there only be 21 million bitcoins?

The 21 million limit is hard-coded into Bitcoin’s protocol by its creator, Satoshi Nakamoto. It was designed to create digital scarcity, prevent inflation through supply expansion, and mirror the finite nature of precious metals like gold.

Can the Bitcoin supply limit be increased?

While Bitcoin is open-source and technically modifiable, changing the 21 million cap would require overwhelming consensus from the network’s global participants. Since doing so would dilute every holder’s value, this scenario is considered virtually impossible.

When is the next Bitcoin halving?

The next Bitcoin halving is expected in April 2028, when the block reward will drop from 3.125 BTC to 1.5625 BTC per block.

Is Bitcoin’s inflation rate lower than gold’s?

Yes. Bitcoin’s current inflation rate is approximately 0.83% annually, compared to gold’s historical supply growth of about 1.6% per year. After the 2028 halving, Bitcoin’s rate will drop to roughly 0.4%.
