Bitcoin Halving History: Complete Timeline of All 4 Halvings and What Comes Next
by AK Arora 
November 28, 2012. Block 210,000.
A miner somewhere added one more block to the Bitcoin blockchain. In that single moment, the reward for doing so dropped from 50 BTC to 25 BTC. Bitcoin’s price at that moment: approximately $12.
Fourteen months later, that same Bitcoin was trading above $1,100.
That was the first Bitcoin halving. Since then, three more have followed — each one cutting the reward in half, each one reducing the daily flow of new Bitcoin entering the world, and each one preceding one of the most significant price movements in financial history.
This is the complete history of all four Bitcoin halvings — what happened, when it happened, how markets responded, and what the pattern tells us about the 2028 halving that is now approximately 669 days away.
What Is the Bitcoin Halving?
Before diving into history, a quick recap of the mechanics.
Bitcoin’s code contains a built-in rule: every 210,000 blocks mined — roughly every four years — the reward paid to miners for validating transactions is cut in half. This is the halving.
Satoshi Nakamoto designed this mechanism deliberately. By reducing the rate at which new Bitcoin enters circulation over time, the halving creates programmatic scarcity. The total supply of Bitcoin is forever capped at 21 million coins. The halving is the mechanism that enforces that cap — slowing new supply gradually until around the year 2140, when the last fraction of Bitcoin will be mined.
The halving does not happen on a fixed calendar date. Instead, it triggers automatically at a specific block height. Since blocks are mined approximately every 10 minutes, the timing can shift slightly depending on network hashrate. However, the four-year cadence has remained remarkably consistent across all halvings so far.
First Bitcoin Halving — November 28, 2012
Block height: 210,000 Date: November 28, 2012 Block reward before: 50 BTC Block reward after: 25 BTC Bitcoin price at halving: ~$12 Daily new supply after: ~3,600 BTC
What Happened
When Bitcoin launched in January 2009, miners earned 50 BTC per block. At the time, Bitcoin was worth fractions of a cent. The 50 BTC reward was partly necessary to incentivise early miners to secure a network that had almost no monetary value.
By late 2012, things had changed. Bitcoin had attracted a small but dedicated community of developers, cypherpunks, and early investors. The price had climbed from effectively zero to approximately $12 — still tiny by today’s standards, but a remarkable appreciation for an asset that was three years old.
The first halving attracted relatively little mainstream attention. Most of the world had never heard of Bitcoin. Furthermore, the crypto infrastructure of today — exchanges, wallets, media coverage — barely existed.
Market Response
Despite the lack of attention, the first halving triggered one of the most dramatic price movements in Bitcoin’s history on a percentage basis.
From approximately $12 at the halving, Bitcoin surged past $1,163 by November 2013 — roughly 12 months later. That represented a gain of approximately 9,200% from the halving price. The bull market attracted wider media coverage and introduced Bitcoin to its first wave of mainstream investors.
However, what followed the peak was equally dramatic. Bitcoin crashed from $1,163 all the way back to approximately $175 by early 2015 — an 85% decline from peak. That pattern of explosive rise followed by steep correction would repeat itself after every subsequent halving.
Key lesson from the first halving: The price effect did not happen immediately. Bitcoin traded sideways for several months before the bull market began in earnest. Patience was required.
Second Bitcoin Halving — July 9, 2016
Block height: 420,000 Date: July 9, 2016 Block reward before: 25 BTC Block reward after: 12.5 BTC Bitcoin price at halving: ~$650 Daily new supply after: ~1,800 BTC
What Happened
By 2016, Bitcoin was a different asset from what it had been in 2012. It had survived its first major crash. Several exchanges had launched. Regulatory frameworks were beginning to emerge in various countries. Institutional awareness — while still minimal — was growing.
The second halving generated far more anticipation than the first. Crypto media covered it extensively. Miners, investors, and developers debated how it would affect the market. Importantly, the price had already begun rising in the months before the halving, suggesting the market was beginning to price in the supply reduction in advance.
However, the immediate price response was muted. Bitcoin actually fell slightly in the days following the July 9 halving. This dampened expectations for those who had anticipated an immediate rally.
Market Response
The real move came later — much later.
Bitcoin climbed steadily through the second half of 2016 and then accelerated dramatically through 2017. By December 2017, Bitcoin reached approximately $19,891 — a gain of roughly 2,960% from the halving price of $650.
The 2017 bull market brought Bitcoin into mainstream consciousness for the first time. News coverage was relentless. Retail investors flooded in. ICOs proliferated. The entire crypto market capitalisation reached nearly $700 billion at peak.
The correction that followed was severe. Bitcoin fell from $19,891 all the way to approximately $3,200 by December 2018 — an 84% decline from peak. Furthermore, most altcoins that had gained alongside Bitcoin lost even more of their value.
Key lesson from the second halving: The percentage return was smaller than the first halving but still extraordinary. Furthermore, the peak came approximately 526 days after the halving — demonstrating that these cycles play out over 12-18 months, not weeks.
Third Bitcoin Halving — May 11, 2020
Block height: 630,000 Date: May 11, 2020 Block reward before: 12.5 BTC Block reward after: 6.25 BTC Bitcoin price at halving: ~$8,600 Daily new supply after: ~900 BTC
What Happened
The third halving occurred in an extraordinary context. COVID-19 had triggered a global financial crisis in March 2020, with Bitcoin crashing from approximately $9,000 to below $4,000 in a single week — one of the sharpest drops in its history.
By May 2020, Bitcoin had recovered to approximately $8,600. Markets globally were being flooded with central bank liquidity — the US Federal Reserve’s balance sheet was expanding rapidly. That macroeconomic backdrop would prove to be a significant tailwind for Bitcoin in the months ahead.
The third halving also coincided with the first wave of meaningful institutional interest. Companies like MicroStrategy and Square began purchasing Bitcoin as a treasury asset later in 2020. PayPal announced Bitcoin support. The narrative of Bitcoin as “digital gold” — a hedge against monetary debasement — gained traction with a new audience.
Market Response
The third halving produced Bitcoin’s largest bull market in absolute dollar terms.
From approximately $8,600 at the halving, Bitcoin reached $68,789 in November 2021 — a gain of approximately 700% from the halving price. More significantly, it represented the first time Bitcoin crossed $20,000, $30,000, $40,000, $50,000, and $60,000.
The peak came approximately 549 days after the halving. The broader crypto market reached a total capitalisation of approximately $3 trillion at peak. DeFi, NFTs, and the metaverse narrative drove significant altcoin gains alongside Bitcoin.
The subsequent correction saw Bitcoin fall from $68,789 to approximately $15,500 by November 2022 — a 77% decline, driven in part by the collapse of the Terra/LUNA ecosystem in May 2022, the FTX collapse in November 2022, and rising interest rates globally.
Key lesson from the third halving: The institutional context changed the character of the cycle. Corporations bought Bitcoin. ETF applications were submitted. The bull market was more sustained than previous cycles, though the percentage gain was smaller. Diminishing returns on percentage basis are a clear trend across cycles.
Fourth Bitcoin Halving — April 20, 2024
Block height: 840,000 Date: April 20, 2024 Block reward before: 6.25 BTC Block reward after: 3.125 BTC Bitcoin price at halving: ~$63,800 Daily new supply after: ~450 BTC
What Happened
The fourth halving arrived in a fundamentally different market from any of its predecessors.
Three months before the halving, in January 2024, the US Securities and Exchange Commission approved the first spot Bitcoin ETFs. BlackRock, Fidelity, and eight other asset managers launched Bitcoin ETFs simultaneously. Within weeks, these products attracted billions in net inflows — with BlackRock’s IBIT becoming one of the fastest-growing ETF products in financial history.
For the first time, the halving’s supply reduction intersected with an institutional demand channel that could absorb entire days of new Bitcoin issuance within hours. The daily new supply dropped from 900 BTC to 450 BTC — while ETF demand on strong days was absorbing thousands of BTC.
Furthermore, Bitcoin had already reached an all-time high of approximately $73,800 in March 2024 — before the halving itself. This was unusual. Previous halvings had all been followed by new all-time highs coming months after the event. The fourth cycle was the first where a new high preceded the halving.
Market Response
The fourth halving’s price trajectory was different from its predecessors in several ways.
Bitcoin initially consolidated after the April 2024 halving, trading sideways and even declining in the following months. The anticipated immediate post-halving surge did not materialise. However, following Donald Trump’s election victory in November 2024 and his administration’s explicitly pro-crypto policy stance, Bitcoin accelerated dramatically.
By October 2025, Bitcoin reached a new all-time high of $126,198 — a gain of approximately 98% from the halving price of $63,800. The peak came approximately 547 days after the halving, strikingly consistent with previous cycle timing.
By June 2026, Bitcoin had pulled back to approximately $66,000 — representing a ~47% decline from peak, the smallest percentage post-cycle correction in Bitcoin’s history.
Key lesson from the fourth halving: The percentage return was dramatically lower than previous cycles — 98% versus 700%, 2,960%, and 9,200% respectively. However, the smaller percentage on a much larger base still represented extraordinary absolute dollar returns. Furthermore, the institutional infrastructure built around the fourth cycle — ETFs, corporate treasuries, sovereign accumulation — created demand dynamics that did not exist before.
All Four Halvings: Side-by-Side Comparison
| Metric | 1st Halving (2012) | 2nd Halving (2016) | 3rd Halving (2020) | 4th Halving (2024) |
|---|---|---|---|---|
| Date | Nov 28, 2012 | Jul 9, 2016 | May 11, 2020 | Apr 20, 2024 |
| Block | 210,000 | 420,000 | 630,000 | 840,000 |
| Reward before | 50 BTC | 25 BTC | 12.5 BTC | 6.25 BTC |
| Reward after | 25 BTC | 12.5 BTC | 6.25 BTC | 3.125 BTC |
| Price at halving | ~$12 | ~$650 | ~$8,600 | ~$63,800 |
| Post-halving ATH | $1,163 | $19,891 | $68,789 | $126,198 |
| % gain from halving | ~9,200% | ~2,960% | ~700% | ~98% |
| Days to ATH | ~367 days | ~526 days | ~549 days | ~547 days |
| Post-ATH correction | -85% | -84% | -77% | ~-47% (ongoing) |
| ETFs available | ❌ | ❌ | ❌ | ✅ |
| Institutional holders | Minimal | Growing | Emerging | Significant |
The Diminishing Returns Pattern
The most striking pattern across Bitcoin’s halving history is the consistent decrease in percentage returns with each cycle.
- First halving: ~9,200% gain
- Second halving: ~2,960% gain
- Third halving: ~700% gain
- Fourth halving: ~98% gain
This pattern makes fundamental sense. As Bitcoin’s market capitalisation grows, it requires proportionally more capital to move the price by the same percentage. Moving a $1 billion asset 100% requires $1 billion. Moving a $1 trillion asset 100% requires $1 trillion. The law of large numbers applies.
However, the absolute dollar returns have remained significant. A $10,000 investment at the fourth halving price of $63,800 would have grown to approximately $19,800 at the October 2025 peak — a $9,800 profit. In absolute terms, meaningful.
Furthermore, the correction depth has also been diminishing. The post-ATH corrections from each halving peak were 85%, 84%, 77%, and approximately 47% so far. Institutional buying and ETF demand appear to be creating a higher floor with each cycle.
What the Pattern Suggests About 2028
The fifth Bitcoin halving is estimated to occur around April 2028, at block height 1,050,000. At that point, the block reward will drop from 3.125 BTC to 1.5625 BTC. Daily new supply will fall to approximately 225 BTC.
Based on historical patterns, if the cycle repeats:
- Peak timing: approximately 540-550 days after the halving — suggesting late 2029 or early 2030
- Peak price: impossible to predict, but historical diminishing returns would suggest smaller percentage gains than the 98% seen after the 2024 halving
- Post-peak correction: potentially smaller than previous cycles given growing institutional base
However, the 2028 cycle will arrive with meaningfully different conditions from any previous halving. By 2028, ETF demand will have been running for four years. Multiple governments may hold Bitcoin as a strategic reserve. The daily ETF absorption could exceed the entire post-halving daily supply of 225 BTC from day one.

How the Halving Affects Bitcoin Miners
Every halving presents miners with an immediate and unavoidable challenge. Their revenue from block rewards drops 50% overnight. Their costs — electricity, hardware, facility — do not.
For each halving to remain viable for miners, one of two things must happen: Bitcoin’s price must increase enough to compensate for the reduced reward, or less efficient miners must exit the market, reducing competition.
Both have happened after every halving. Less efficient miners have exited after each event, causing temporary hashrate drops. The network’s difficulty adjustment then makes mining easier for remaining miners, restoring profitability. Within weeks to months, new more efficient hardware comes online, hashrate recovers, and the mining ecosystem has adapted.
This miner economics cycle has repeated four times. Each time, the industry has emerged more concentrated among large-scale, efficient operations — and more reliant on cheap renewable energy sources.
The long-term question that becomes more pressing with each halving is transaction fees. As block rewards approach zero across future halvings, transaction fees must eventually replace them as the primary miner revenue source. Whether that transition happens smoothly is one of Bitcoin’s most significant open questions.
FAQ
How many Bitcoin halvings have there been?
Four. The halvings occurred on November 28, 2012 (block 210,000), July 9, 2016 (block 420,000), May 11, 2020 (block 630,000), and April 20, 2024 (block 840,000).
When is the next Bitcoin halving?
The fifth Bitcoin halving is estimated to occur around April 2028, at block height 1,050,000. The exact date depends on average block times between now and then.
Does Bitcoin price always go up after a halving?
Historically, yes — Bitcoin has reached a new all-time high within 18 months of every halving. However, past performance does not guarantee future results. Furthermore, the timing varies significantly — the first halving’s peak came 367 days later, while the third and fourth cycles peaked approximately 547-549 days after.
Why does Bitcoin have a halving?
Satoshi Nakamoto designed the halving to create programmatic scarcity. By reducing the rate of new supply over time, Bitcoin mimics the economics of a scarce commodity like gold — where the difficulty and cost of extraction naturally limit supply growth. This design ensures the total supply never exceeds 21 million coins.
How does the halving affect miners?
The halving immediately cuts miners’ block reward revenue by 50%. Less efficient miners often exit the market after halvings, causing temporary hashrate drops. However, Bitcoin’s difficulty adjustment algorithm reduces mining difficulty to compensate, restoring profitability for remaining miners. The industry has successfully adapted after all four previous halvings.
What was Bitcoin’s price at each halving?
The prices were approximately $12 (2012), $650 (2016), $8,600 (2020), and $63,800 (2024).
Final Word
Bitcoin’s halving history tells a remarkably consistent story across four very different market environments.
Each halving has reduced new supply. Each has been followed by a new all-time high. Each cycle has produced smaller percentage returns than its predecessor on a percentage basis. And each cycle has arrived with more institutional infrastructure, more regulatory clarity, and more mainstream acceptance than the one before.
The fifth halving in 2028 will inherit all of that accumulated progress — plus an ETF ecosystem, potential sovereign Bitcoin reserves, and a daily supply of just 225 new coins. Whether those conditions produce another historic bull market or a more muted cycle is genuinely unknown.
What is known is that the halving is the most predictable monetary event in financial markets. The date can be estimated years in advance. The supply impact is mathematically certain. For investors, understanding the history of how markets have responded to each halving is the essential foundation for thinking about what comes next.
