How Much Bitcoin Is Left to Be Mined — And What Happens When It’s Gone?

Bitcoin has not started 2026 well. After reaching an all-time high near $126,000 in late 2025, the price has fallen sharply and is currently trading around the $68,000 region in mid-February 2026. That kind of 50 percent retracement always resets sentiment and forces people to zoom out.

It got me thinking about something more fundamental than short-term price action: scarcity.

With a fixed cap of 21 million coins, Bitcoin’s supply is mathematically limited. But how much is actually left to be mined?

And when the final coin is issued, what happens to the network, to miners, and potentially to the price? More importantly, is scarcity alone enough to drive long-term value?

Bitcoin’s Supply Model Explained

Bitcoin has a hard supply cap of 21,000,000 coins. This limit is embedded in the protocol and enforced by network consensus.

New bitcoin enters circulation through mining. Miners validate transactions and secure the network. In return, they receive two types of rewards:

• The block subsidy (newly created bitcoin)
• Transaction fees (paid by users)

The block subsidy follows a strict schedule:

• It started at 50 BTC per block in 2009.
• It halves every 210,000 blocks (roughly every four years).
• It continues halving until it eventually reaches zero.

This structure creates a predictable issuance curve that declines over time.

How Much Bitcoin Has Already Been Mined?

As of February 2026:

• Roughly 19.97 to 19.98 million BTC have already been mined.
• Approximately 1.02 million BTC remain to be issued.
• Around 95 percent of all bitcoin that will ever exist is already in circulation.

That means the majority of Bitcoin’s supply was created in its early years. What remains is the long tail of diminishing issuance.

Here’s a simplified overview:

We are very close to the 20 million milestone, which further emphasizes how late we are in Bitcoin’s issuance timeline.

Why the Last Million Takes Over a Century

The halving mechanism is why the final portion of Bitcoin takes so long to mine.

Following the April 2024 halving, the block subsidy is now 3.125 BTC per block.

With approximately 144 blocks mined per day:

• Around 450 BTC are created daily.
• Roughly 164,000 BTC are issued per year.

After the next halving:

• The subsidy drops to 1.5625 BTC per block.
• Daily issuance falls to about 225 BTC.

Each halving cuts issuance in half again. Over time, the new supply becomes extremely small. The final satoshis (the smallest unit of bitcoin) are expected to be mined around the year 2140.

Most of the supply was front-loaded. The final 5 percent is distributed slowly across more than a century.

What Happens When All Bitcoin Is Mined?

When the block subsidy reaches zero:

• No new bitcoin will be created.
• The total supply will be fixed permanently.
• Miners will no longer receive block rewards in new BTC.

However, the network does not stop functioning.

Miners will continue to earn transaction fees. Every transaction included in a block pays a fee, and those fees go to the miner.

The revenue structure shifts from:

Block subsidy + fees
to
Fees only

Blocks will still be produced approximately every ten minutes. Bitcoin will still operate as normal. The only change is how miners are compensated.

The Security Budget Question

The real debate is not whether Bitcoin survives without new coins — it does.

The real question is whether transaction fees alone will be enough to incentivize miners to maintain high levels of security.

This depends on several factors:

• Total on-chain transaction demand
• Willingness of users to pay fees
• Bitcoin’s market price
• Mining competition and efficiency

If Bitcoin evolves into a high-value global settlement layer, transaction fees could become significant enough to sustain miners.

If on-chain activity remains limited, fee revenue may not fully replace the declining subsidy.

The protocol assumes a gradual transition. The subsidy does not disappear overnight — it declines over more than 100 years. This gives the fee market time to mature.

Can Scarcity Drive the Price Higher?

This is the part that ties back to the current market.

Bitcoin’s supply is fixed. Fiat supply is not. That distinction is powerful. But scarcity alone does not automatically create price increases.

Price depends on:

• Demand
• Liquidity
• Institutional flows
• Macro conditions
• Regulatory clarity
• Market sentiment

Scarcity becomes powerful only if demand remains constant or increases while supply growth approaches zero.

We are already at a stage where the new supply is relatively small compared to the circulating supply. Daily issuance today is tiny relative to global trading volume.

So while the remaining 1 million BTC is meaningful psychologically, its issuance impact on price becomes smaller with each halving.

Scarcity is a structural tailwind. It is not a short-term price catalyst.

Long-Term Outlook

By 2032, issuance will be dramatically smaller than today. By the late 2030s, new supply will be minimal relative to total circulating coins.

At that stage:

• Bitcoin becomes fully supply-constrained.
• Miner economics depend more heavily on fees.
• Market structure may shift toward long-term holders and institutional custody.

The biggest takeaway is this:

Bitcoin’s inflation rate is already extremely low and trending toward zero. The remaining supply is predictable, transparent, and mathematically constrained.

The issuance schedule is not speculation — it is code.

Final Thoughts

Bitcoin has dropped sharply to start 2026, falling from around $126,000 to roughly $68,000. Short-term price action always dominates headlines. But the supply mechanics remain unchanged.

About 1 million Bitcoins remain to be mined. The last satoshis won’t arrive until around 2140. When that day comes, miners will rely entirely on transaction fees, and Bitcoin will operate on a fully fixed monetary base.

Scarcity is one of Bitcoin’s core design features. Whether it becomes the dominant price driver in the coming years depends not just on supply — but on demand, adoption, and global economic conditions.

The supply side is finite. The demand side is still being written.
