How Many Bitcoins Are Left to Mine in 2026?
About 9.1 lakh bitcoins (910,000 BTC) are left to mine of 21 million; 95.7% already exist. See the halving schedule, daily issuance and the final coin date.
About 910,000 bitcoins (roughly 9.1 lakh BTC) are left to mine. On 27 September 2026 around 20.09 million of the 21 million maximum were already in circulation, which means about 95.7% of all bitcoin has been mined. New coins arrive at about 450 BTC a day, and the pace halves roughly every four years, so the last fraction will not be mined until around the year 2140.
Key takeaways
- Bitcoin's supply is capped at 21 million coins by its code. About 20.09 million existed on 27 September 2026.
- That leaves about 910,000 BTC still to be mined, worth about ₹7.4 lakh crore at about ₹81.4 lakh per bitcoin on that date.
- Miners earn 3.125 BTC per block since the April 2024 halving, about 450 BTC a day.
- The next halving, to 1.5625 BTC per block, is expected in 2028. About 99% of all bitcoin should exist by the mid-2030s.
- Several million coins are thought to be lost for good, so the usable supply is smaller than the circulating figure.

Why only 21 million bitcoins will ever exist
Bitcoin's code creates new coins only as a reward to the miner who adds each new block. That reward started at 50 BTC in 2009 and is cut in half every 210,000 blocks, roughly every four years. Because the reward keeps halving, the total adds up to just under 21 million and can never pass it. Changing this would need almost the whole network to agree to new software, which is why the cap is considered one of Bitcoin's firmest rules. Our explainer on what is Bitcoin covers the basics.
The halving schedule: how supply was released
| Era | Block reward | Period (approx.) | Total mined by end of era | Share of 21 million |
|---|---|---|---|---|
| 1 | 50 BTC | 2009 to Nov 2012 | 10,500,000 | 50% |
| 2 | 25 BTC | 2012 to Jul 2016 | 15,750,000 | 75% |
| 3 | 12.5 BTC | 2016 to May 2020 | 18,375,000 | 87.5% |
| 4 | 6.25 BTC | 2020 to Apr 2024 | 19,687,500 | 93.75% |
| 5 (now) | 3.125 BTC | 2024 to 2028 | 20,343,750 | 96.9% |
| 6 | 1.5625 BTC | 2028 to about 2032 | 20,671,875 | 98.4% |
| 7 | 0.78125 BTC | about 2032 to 2036 | 20,835,938 | 99.2% |
Half of all bitcoin was mined in the first four years. Each era since has added half as much as the one before. Halving dates depend on how quickly blocks are found, so future dates are estimates. Our guide to the Bitcoin halving and the next halving date in 2028 explains what it means for miners and prices.
When will the last bitcoin be mined?
Each block's reward keeps halving until it becomes smaller than 1 satoshi, the smallest unit Bitcoin can record. That happens after 33 halvings, which works out to around the year 2140. But the last century of mining will add very little: about 99% of all coins should exist by the mid-2030s. The final figure will be slightly under 21 million because of rounding in the reward maths and a few coins that were never claimed, such as the reward in the very first block.
What happens when mining ends?
Miners will still be needed to secure the network after new coins stop. Instead of block rewards, they will earn only the transaction fees users pay. Whether fees alone will be enough to keep the network secure is an open debate, and the answer depends on how much people use Bitcoin in future. The shrinking reward is already a live issue: after each halving, miners with high electricity costs struggle unless the price rises. We look at the Indian angle in is Bitcoin mining legal and profitable in India.
Lost bitcoins: the real supply is smaller
Of the 20.09 million coins mined, a large amount is believed to be permanently lost: coins in wallets whose keys were forgotten, hard drives thrown away, or early coins that have not moved in over a decade. Estimates commonly run to several million BTC, but nobody can know for sure, because a coin that has not moved is not necessarily lost. Around 1.1 million early coins are widely attributed to Satoshi Nakamoto and have never moved. We cover the biggest holders in who owns the most bitcoin.
What the fixed supply means for Indian investors
A capped supply is part of why people compare Bitcoin with gold; see Bitcoin vs gold for Indian investors. But scarcity alone does not guarantee a rising price. Demand can fall, and bitcoin has dropped more than 70% from its highs several times in its history. You do not need a whole coin: you can buy a small fraction, and our guide on 1 satoshi in rupees shows what small amounts buy. Use an exchange from the FIU-registered list, and remember that gains are taxed at 30% plus cess with 1% TDS on sales, as explained in our crypto tax guide.
