The ticking clock is getting louder—Bitcoin’s fourth halving is just around the corner.
Halving is one of Bitcoin’s most powerful and enduring memes. Its simplicity is striking, its design elegant, its transparency disarming, and its impact undeniable. More than just a technical event, the halving represents a core economic mechanism that shapes Bitcoin’s scarcity, value proposition, and long-term trajectory.
What Is the Bitcoin Halving?
At the heart of Bitcoin’s monetary policy lies a simple yet revolutionary rule: every 210,000 blocks (approximately every four years), the block reward given to miners is cut in half. This process, known as the halving, ensures that the total supply of Bitcoin will never exceed 21 million units.

Here’s how it works:
- Genesis to Block 210,000: Miners received 50 BTC per block.
- Block 210,001: The reward dropped to 25 BTC.
- Block 420,001: It halved again to 12.5 BTC.
- Block 630,001 (2020): Reduced to 6.25 BTC.
- Next Halving (~2024): Will drop to 3.125 BTC per block.
This geometric reduction follows a clean mathematical formula:
Sum(0.5^n) × 50 × 210,000 ≈ 21 million BTC
And with new blocks mined roughly every 10 minutes:
210,000 blocks × 10 minutes ÷ 60 ÷ 24 ÷ 365 ≈ 4 years
This is Bitcoin’s algorithmic central bank—a rules-based, decentralized monetary policy that operates without human intervention. No lobbying, no inflation surprises, no political manipulation. Just code, math, and time.
Why the Halving Matters
Bitcoin’s halving isn’t just a supply-side adjustment—it’s a foundational event that reinforces digital scarcity. As the rate of new BTC issuance slows, the asset becomes increasingly "hard." This concept is often measured by the Stock-to-Flow (S2F) ratio, which compares existing reserves to new annual production.
Before the 2024 halving, Bitcoin’s S2F ratio sits between 57 and 59, already surpassing silver and approaching gold (~62). But after the halving? It jumps to nearly 120—more than double that of gold.

This makes Bitcoin not only the hardest monetary asset in human history but potentially the most resilient store of value ever created. Unlike gold, which can still be mined at significant rates, or fiat currencies, which can be printed at will, Bitcoin’s supply is fixed, predictable, and immutable.
Historical Patterns: What Past Halvings Tell Us
While past performance doesn’t guarantee future results, historical trends offer valuable insights.
Let’s look at what happened after previous halvings:
- 2012 Halving (November): One year later, BTC surged 7,745%, rising from ~$12 to over $1,000.
- 2016 Halving (July): Within a year, price climbed 460%, eventually peaking near $20,000 in late 2017.
- 2020 Halving (May): BTC rose 670% within a year, breaking all-time highs and reaching nearly $69,000 by late 2021.
A common myth is that each cycle brings diminishing returns. But the data shows otherwise—the percentage gains post-halving have remained explosive across cycles.
That said, one long-held belief has been challenged: the idea that each bull market bottom stays above the previous cycle’s peak. In late 2022, BTC briefly dipped below $16,000—well under the 2017 high of ~$20,000—proving markets don’t follow rigid rules.
Still, the broader narrative holds: halvings catalyze bull markets.
As刘教链 once noted:
“The halving drives the bull run—not the other way around. It is an internal mechanism, pre-programmed into Bitcoin’s blockchain timeline. It doesn’t care about sentiment, macro conditions, or media hype. It simply executes—on schedule.”
This mechanical inevitability makes the halving a powerful internal trigger, while external factors like institutional adoption or regulatory shifts act as accelerants.
The 2024 Halving: A Different Beast
This upcoming halving isn’t just another checkpoint—it’s a turning point.
For the first time:
- Institutional participation is widespread. ETFs in the U.S., custody solutions, and balance-sheet adoption by major corporations have created structural demand.
- Global macro uncertainty—inflation, debt levels, geopolitical tensions—has driven more investors toward hard assets.
- Bitcoin’s network maturity means greater liquidity, deeper markets, and stronger resilience against shocks.
Combine these with the halving-induced supply shock, and you have a recipe for unprecedented price pressure.
Even if demand remains flat, cutting supply in half creates upward pressure on price. But with growing adoption and limited sell pressure from miners (many of whom are now holding), the imbalance could be dramatic.

Frequently Asked Questions (FAQ)
Q: When is the next Bitcoin halving?
A: The fourth Bitcoin halving is expected in April or May 2024, occurring when the block height reaches approximately 840,000.
Q: How does the halving affect Bitcoin’s price?
A: Historically, reduced supply has led to significant price increases within 12–18 months post-halving. While not guaranteed, scarcity dynamics tend to favor upward price movement if demand stays constant or grows.
Q: Will mining become unprofitable after the halving?
A: Some less-efficient miners may exit, but technological improvements and rising prices typically offset reduced rewards. Mining centralization risks exist but are mitigated by global competition and market forces.
Q: Can the halving be canceled or delayed?
A: No. The halving is hardcoded into Bitcoin’s protocol. Altering it would require near-unanimous consensus across the network—an extremely unlikely scenario.
Q: Does the halving always lead to a bull market?
A: Not instantly. Markets often experience consolidation or sideways movement for months after the event before breaking out. Patience is key.
Q: How many Bitcoins are left to mine?
A: As of early 2025, over 93% of all Bitcoins have already been mined—around 19.7 million are in circulation. Only about 1.3 million remain to be gradually released over the next century.
Standing at the Foot of a New Curve
We may be standing at the base of a new S-curve—a moment where innovation meets adoption on a global scale. The cliff ahead is steep; the view obscured by fog. But one thing is clear: Bitcoin’s design ensures that each halving makes it harder to ignore.
With supply dwindling and institutional interest growing, the stage is set for another transformative chapter in Bitcoin’s history.
👉 Prepare for the next phase of Bitcoin's evolution
Whether you're a long-term holder or a curious observer, understanding the halving is essential to navigating what comes next. It’s not just about how many times BTC might multiply—it’s about recognizing the power of programmed scarcity in a world drowning in inflation.
