What is Bitcoin Halving? All Halvings, Price Data, and 2028 Outlook

Even though there’s still some time until the next so-called Bitcoin Halving in 2028, it’s worth taking a closer look at this event. The halving is one of the most important features that Satoshi Nakamoto designed during the early programming of the digital currency. It halves the reward per mined block. In this article, we explain how the halving works, what impact it has on the Bitcoin price, and when the next halving will take place.

What is the Bitcoin Halving?

Specifically, this means: every 210,000 blocks or approximately every 4 years, Bitcoin mining rewards paid to miners are cut in half. This rule is firmly embedded in the code of every block and cannot be changed.

Combined with the fact that the number of bitcoins is limited to 21 million coins, the halving ensures that the supply of new bitcoins grows more slowly over time. It becomes more difficult to calculate the number sequences and requires more computing power. And that power costs money.

All Bitcoin Halvings at a Glance:

Why does the Bitcoin Halving exist?

The halving systematically reduces the supply of new bitcoins. As a result of this limited availability and increasing demand with growing awareness, the value of a bitcoin rises. That’s at least the theory behind Satoshi’s design decision.

Through the halving, Bitcoin’s inflation rate decreases with each cycle. After the fourth halving in April 2024, Bitcoin’s annual inflation rate is below 1%, making it lower than that of gold. This mechanism makes Bitcoin a deflationary asset, comparable to a precious metal whose extraction becomes increasingly difficult.

How does the halving affect the Bitcoin price?

The big question with every halving: What happens to the price? Historical data shows a clear pattern, although past performance is no guarantee of future results.

Historical Price Development After Halvings

After each of the previous halvings, the Bitcoin price rose significantly in the following 12 to 18 months:

• 2012: Price on halving day ~$12. Within 12 months, BTC rose to over $1,100. A gain of over 9,000%.
• 2016: Price on halving day ~$650. By December 2017, BTC rose to nearly $20,000. A gain of around 2,900%.
• 2020: Price on halving day ~$8,570. By November 2021, BTC reached an all-time high of ~$69,000. A gain of around 700%.
• 2024: Price on halving day ~$63,850. By October 2025, BTC reached a new ATH of ~$109,000. As of April 2026, BTC is at around $77,000. A gain of around 21% after 12 months.

The pattern is clear: The percentage gains after the halving are getting smaller from cycle to cycle. The 2024 halving has shown the weakest post-halving performance in history so far.

The Chain Reaction After the Halving

What many overlook is the time factor. The effects of the halving on the price don’t occur immediately, but with a delay. Crypto analyst Joe Burnett of III Capital describes the mechanism as a chain reaction: After the halving, miners sell bitcoins to cover their operating costs. At the same time, their revenue is halved. Less profitable miners shut down production. This reduces the supply of newly mined bitcoins. The full effect only unfolds over months.

Is the Halving Effect Weakening?

With each halving, a smaller absolute amount of new bitcoins is halved. At the 2024 halving, daily production dropped from 900 to 450 BTC. For comparison: In the first quarter of 2026 alone, around $18.7 billion flowed into Bitcoin spot ETFs. Institutional demand exceeds daily mining production by a multiple.

Many analysts therefore argue that the halving effect on the price decreases with each cycle. Institutional inflows, regulatory developments, and macroeconomic factors (interest rates, inflation, geopolitical crises) influenced the price more strongly in 2024/2025 than the halving itself. The Kaiko study on the anniversary of the 2024 halving confirms: Bitcoin’s 60-day volatility has fallen from over 200% in 2012 to below 50%.

The Bitcoin Halving 2024 in Retrospect

On April 20, 2024, the block reward at block 840,000 was successfully halved from 6.25 to 3.125 BTC. It was the fourth Bitcoin halving in history.

Every 210,000 blocks, the produced Bitcoin is halved. The intended block time is ten minutes, although deviations occur repeatedly.

What happened next: Bitcoin reached a new all-time high of around $109,000 in October 2025, but then corrected significantly. In April 2026, the price is around $77,000. While the fourth halving led to a new ATH, the performance is weak in historical comparison.

The Stock-to-Flow model developed by PlanB, which relates the existing quantity of an asset to its annual production, had correctly predicted the direction. However, the absolute price targets of the model were not reached. The model remains controversial in the community.

When is the next Bitcoin halving?

The fifth Bitcoin halving is expected to take place in April 2028, at block 1,050,000. The block reward will then drop from 3.125 to 1.5625 BTC.

The exact date cannot be predicted with certainty, as it depends on the actual block production rate. Fluctuations in the hashrate can shift the date forward or backward by several weeks.

After the fifth halving, less than 5% of all bitcoins will remain to be mined. Daily production drops to around 225 BTC per day.

What does the halving mean for miners?

For miners, every halving is a significant event. Their revenue from block rewards is cut in half overnight. It becomes more difficult to calculate the number sequences and requires more computing power. And that power costs money. In the past, several bitcoins per day could still be calculated on a home PC. Nowadays, it would take years for the same number of bitcoins.

The consequence: After each halving, inefficient miners drop out of the market. Only operators with access to cheap energy and modern hardware remain profitable. At the same time, the importance of transaction fees as a revenue source increases. After the 2024 halving, fees briefly rose to record highs, partly due to the launch of the Runes protocol.

In the long term, transaction fees will replace the block reward as the main revenue source for miners.

Conclusion

The Bitcoin halving is a fundamental component of Bitcoin’s monetary policy. It ensures a predictable, declining inflation and makes Bitcoin one of the few assets with a fixed, transparent supply structure.

Historically, every halving has led to a price increase in the following 12 to 18 months. However, the percentage gains are getting smaller from cycle to cycle, and the influence of institutional inflows, regulation, and macroeconomics is increasing. The halving alone is no guarantee of rising prices.

Whatever happens, a halving is always a special moment in the Bitcoin world.
