On April 20, 2024, Bitcoin underwent its fourth halving, cutting the block reward from 6.25 BTC to 3.125 BTC. This pre-programmed event, which occurs roughly every four years, is one of the most significant moments in Bitcoin’s monetary cycle. Understanding the halving and its historical impact is essential for anyone trying to make sense of Bitcoin’s price movements and long-term trajectory.
What Is the Bitcoin Halving?
The Bitcoin halving is a built-in feature of Bitcoin’s code. Every 210,000 blocks (approximately four years), the reward that miners receive for validating a block is cut in half. This process will continue until all 21 million Bitcoin have been mined, expected around the year 2140.
The halving serves a critical economic purpose: it creates a predictable, decreasing supply schedule. Unlike fiat currencies, which can be printed without limit, Bitcoin’s supply is absolutely scarce. Each halving reduces the rate at which new Bitcoin enters circulation, creating a supply shock that has historically driven significant price appreciation.
The halving schedule:
| Halving | Date | Block | Reward Before | Reward After | BTC Price (approx.) |
|---|---|---|---|---|---|
| 1st | Nov 28, 2012 | 210,000 | 50 BTC | 25 BTC | $12 |
| 2nd | Jul 9, 2016 | 420,000 | 25 BTC | 12.5 BTC | $650 |
| 3rd | May 11, 2020 | 630,000 | 12.5 BTC | 6.25 BTC | $8,700 |
| 4th | Apr 20, 2024 | 840,000 | 6.25 BTC | 3.125 BTC | $64,000 |
| 5th | ~2028 | 1,050,000 | 3.125 BTC | 1.5625 BTC | TBD |
Historical Halving Performance
Bitcoin has now experienced four halvings, and the pattern is remarkably consistent:
2012 Halving
The first halving reduced the reward from 50 to 25 BTC. At the time, Bitcoin was trading at $12 and was known only to a small community of cypherpunks and libertarians. Within 12 months, Bitcoin rose to over $1,100 – a 9,000% increase. The 2013 bull run was driven by the first wave of mainstream media attention and the launch of early exchanges.
2016 Halving
The second halving reduced the reward from 25 to 12.5 BTC. Bitcoin was trading at $650, and the ecosystem was more mature but still niche. By December 2017, Bitcoin reached nearly $20,000 – a 2,900% increase. The 2017 bull run was driven by the ICO craze and the first wave of retail speculation.
2020 Halving
The third halving reduced the reward from 12.5 to 6.25 BTC. Bitcoin was trading at $8,700, and COVID-19 had just triggered a global market crash. By November 2021, Bitcoin reached $69,000 – a 690% increase. The 2021 bull run was driven by institutional adoption, stimulus money, and the DeFi/NFT boom.
2024 Halving
The fourth halving reduced the reward from 6.25 to 3.125 BTC. Bitcoin was trading at $64,000, and spot Bitcoin ETFs had just been approved. The effects are still unfolding, but early indicators suggest another significant cycle driven by ETF inflows, institutional adoption, and the post-halving supply shock.
Why the Halving Matters
The halving creates a fundamental supply-demand imbalance. Miners receive fewer new Bitcoin, which means less selling pressure from mining operations. Meanwhile, demand from ETFs, institutions, and retail investors continues to grow. This supply squeeze, combined with steady or increasing demand, creates upward pressure on price.
To illustrate: before the 2024 halving, miners were receiving approximately 900 new BTC per day (6.25 BTC per block x 144 blocks per day). After the halving, this dropped to 450 BTC per day. Meanwhile, Bitcoin ETFs were buying thousands of BTC per day. The supply-demand imbalance was stark.
The 2024 Halving: What Makes It Different
The 2024 halving occurred in a unique environment. For the first time, spot Bitcoin ETFs were already approved and accumulating billions in inflows. This institutional demand was absorbing a significant portion of available supply even before the halving reduced new issuance.
Additionally, the 2024 halving took place against a backdrop of global monetary expansion, geopolitical uncertainty, and growing recognition of Bitcoin as a legitimate asset class. The Ordinals and BRC-20 boom had also demonstrated new sources of demand for Bitcoin block space.
Looking Ahead: The Next Cycle
While past performance does not guarantee future results, the historical pattern suggests that the 12-18 months following a halving tend to be the most bullish period in Bitcoin’s cycle. If history rhymes, the 2025-2026 period could see significant price appreciation as the supply shock works its way through the market.
However, each cycle is different, and the increasing maturity of the Bitcoin market means that future returns may be more moderate than previous cycles. The base is larger, the market is more efficient, and institutional participation has changed the dynamics significantly.
The halving is Bitcoin’s way of enforcing scarcity in a world of abundance. It’s the monetary policy that no central bank would ever voluntarily adopt – and that’s exactly why it works.

The Long-Term View
Regardless of short-term price movements, the halving reinforces Bitcoin’s core value proposition: absolute scarcity in a world of infinite money printing. This is what makes Bitcoin unique among all assets, and why the halving remains one of the most anticipated events in the financial calendar.
As we look toward the fifth halving in 2028, the pattern is clear: each halving makes Bitcoin more scarce, more valuable, and more important to the global financial system. The halving is not just an event – it is the heartbeat of Bitcoin’s monetary policy.

The 2024 Halving: A New Era
The fourth Bitcoin halving took place on April 20, 2024, reducing the block reward from 6.25 BTC to 3.125 BTC. This halving was different from previous ones in several important ways. First, it occurred alongside the launch of spot Bitcoin ETFs, which created massive new demand. Second, it took place in a macroeconomic environment of high interest rates and quantitative tightening.
The combination of reduced supply (from the halving) and increased demand (from ETFs) created a powerful dynamic. In the months following the halving, Bitcoin reached new all-time highs, validating the thesis that halvings are bullish for Bitcoin’s price.
Miner Economics After the Halving
The halving put significant pressure on miners. With block rewards cut in half, miners needed either a higher Bitcoin price or lower operating costs to remain profitable. The least efficient miners were forced to shut down, leading to a temporary drop in hash rate.
However, the Bitcoin price increase that followed the halving more than compensated for the reduced block rewards. By late 2024, mining revenue was at all-time highs when measured in dollar terms, even though the BTC-denominated block reward was at its lowest level ever.
The Stock-to-Flow Model
The stock-to-flow (S2F) model, popularized by PlanB, attempts to predict Bitcoin’s price based on its scarcity. The model treats Bitcoin like a commodity, comparing the existing stock (total supply) to the flow (annual production). After each halving, the flow is cut in half, making Bitcoin more scarce and, according to the model, more valuable.
While the S2F model has been controversial – critics argue that it oversimplifies the relationship between scarcity and value – it has been remarkably accurate in predicting Bitcoin’s price trajectory after previous halvings. The 2024 halving has continued this pattern.
Looking Ahead to 2028
The next halving, expected in 2028, will reduce the block reward to 1.5625 BTC. By then, transaction fees will need to play a larger role in miner revenue. The development of Ordinals, BRC-20 tokens, and other on-chain applications is already driving fee revenue, providing a preview of the fee-driven future of Bitcoin mining.
