The latest Bitcoin halving has once again sparked global interest among investors, traders, and crypto enthusiasts. As the fourth halving event in Bitcoin’s history, it marks a pivotal moment in the digital currency’s economic model. But what exactly is the Bitcoin halving, and how does it impact the market? Drawing insights from industry experts like Krysto de Wet, South African market manager at Luno, this article explores the mechanics, historical trends, and future implications of Bitcoin's halving cycle.
Understanding the Bitcoin Halving Mechanism
Every four years—or more precisely, every 210,000 blocks mined—Bitcoin undergoes a programmed supply reduction known as the halving. This built-in feature of the Bitcoin protocol cuts the block reward for miners in half. In the most recent event, the reward dropped from 6.25 BTC to 3.125 BTC per block.

This deflationary design ensures that Bitcoin remains scarce, mimicking precious assets like gold. With a hard cap of 21 million coins, the last Bitcoin is expected to be mined around the year 2140. The halving mechanism slows down new supply entering the market, reinforcing Bitcoin’s reputation as “digital gold.”
Krysto de Wet explains:
“The halving is embedded in Bitcoin’s algorithm—it’s a built-in tightening measure that occurs roughly every four years. No one can predict with certainty whether prices will rise, fall, or stay flat after the event.”
Historical Trends: What Past Halvings Tell Us
Looking back at previous cycles offers valuable context for understanding potential price movements following each halving.
First Halving (2012) – The Humble Beginning
In November 2012, Bitcoin underwent its first halving when the price was just above $12**. At that time, there were only about **43,000 Bitcoin addresses** holding more than $1 worth of BTC. Fast forward to the end of 2013, and Bitcoin surged to nearly $1,000**—an astonishing increase of over 8,000%.
Second Halving (2016) – Institutional Curiosity Grows
The second halving occurred in July 2016 with Bitcoin trading around $640**. Over the next year, momentum built steadily, pushing prices up to **$2,550 by July 2017. This period saw increased media attention and early signs of institutional interest.
Third Halving (2020) – A New Era Begins
On May 11, 2020, Bitcoin halved again with a market price near $8,750**. Within 18 months, it skyrocketed to an all-time high of approximately **$62,000, driven by macroeconomic uncertainty, stimulus-driven inflation fears, and growing adoption by companies like Tesla and MicroStrategy.
These historical patterns suggest that while the halving doesn’t trigger immediate price spikes, it often sets the stage for bull markets in the 12–18 months that follow.
How Is This Cycle Different?
While past halvings were followed by significant rallies, experts note that the 2025 cycle stands out due to several unique factors.
Firstly, Bitcoin reached new all-time highs before the halving—an unprecedented development. In prior cycles, price surges typically came after the event. This pre-halving peak suggests that much of the optimism may already be priced in.
Secondly, regulatory progress in major economies has changed the landscape. In early 2024, the U.S. Securities and Exchange Commission (SEC) approved the first spot Bitcoin exchange-traded funds (ETFs). Since then, over $120 million has flowed into these products, signaling strong institutional demand.
However, data also shows divergence. In March 2025, despite record highs on platforms like Luno, approximately $83 million was withdrawn from Bitcoin ETFs—indicating profit-taking or cautious sentiment among large investors.
Krysto de Wet observes:
“This cycle is vastly different. It’s the first time Bitcoin has halved near an all-time high. Market dynamics have evolved with ETFs, global regulations, and broader awareness.”
Does the Halving Directly Affect Price?
Despite widespread speculation, many analysts argue that the halving itself has limited direct impact on price action.

While reduced supply can create upward pressure over time, markets are forward-looking—the effects are often anticipated and absorbed before the actual event. As de Wet notes:
“Even if you believe the halving drives prices, there’s no guarantee history will repeat itself.”
Other factors such as macroeconomic conditions (interest rates, inflation), geopolitical events, regulatory shifts, and technological upgrades play equally important roles in shaping price trends.
Additionally, long-term holders and retail investors aren’t directly affected by the halving—their holdings remain unchanged. Only miners see a direct impact through reduced block rewards. Some smaller mining operations may struggle to remain profitable unless they have low energy costs or upgraded hardware.
Supply Dynamics: Scarcity Without Shrinkage
A common misconception is that halving reduces total Bitcoin supply. That’s incorrect.
Bitcoin’s total supply continues to grow—albeit at a slowing rate—until it reaches its maximum cap of 21 million coins around 2140. Each halving simply slows down the pace of new coin creation.
For example:
- Post-first halving: ~300 BTC mined daily
- Post-fourth halving: ~450 BTC mined daily (at 3.125 BTC per block)
Wait—why more? Because faster block times and network improvements mean blocks are confirmed slightly quicker than every 10 minutes on average.
Still, the psychological effect of scarcity remains powerful. With over 46 million addresses now holding at least $1 worth of Bitcoin (compared to just 43,000 in 2012), awareness and accessibility have exploded.
Frequently Asked Questions (FAQ)
Q: What is the Bitcoin halving?
A: The Bitcoin halving is a programmed event that reduces the mining reward by half every 210,000 blocks (~4 years), slowing down new supply issuance.
Q: Does the halving cause prices to go up?
A: Historically, bull runs have followed halvings—but not immediately. Prices tend to rise months later due to a combination of reduced supply and growing demand.
Q: How many Bitcoins are left to be mined?
A: As of 2025, over 19.8 million BTC have been mined. Less than 1.2 million remain to be released gradually over the next century.
Q: Are all halvings followed by price increases?
A: Not guaranteed. While past cycles show post-halving rallies, market conditions evolve. Factors like regulation, macro trends, and investor sentiment also shape outcomes.
Q: Does the halving affect my existing Bitcoin holdings?
A: No. Your wallet balance remains unchanged. The halving only affects how many new Bitcoins miners receive per block.
Q: Could mining become unprofitable after halvings?
A: For some small-scale miners, yes—especially those with high electricity costs. However, efficient operations often survive by upgrading equipment or relocating to low-cost regions.

Final Thoughts
The Bitcoin halving is more than a technical adjustment—it’s a powerful symbol of scarcity in a world of endless monetary expansion. While history shows a pattern of post-halving growth, today’s market is far more complex than in 2012 or even 2020.
With institutional adoption accelerating through ETFs, global regulatory frameworks taking shape, and public awareness at an all-time high, the narrative around Bitcoin continues to mature.
Whether you're a long-term holder or a strategic trader, understanding the halving helps you make informed decisions—not based on hype, but on economic fundamentals.
As Krysto de Wet reminds us: Predictions are uncertain. But one thing remains clear—Bitcoin’s deflationary design ensures its supply will always be limited, making it a unique asset in modern finance.
