Every four years, something quiet but massive happens on the Bitcoin network. No news alert. No press conference. Just a silent code change that cuts the number of new bitcoins created in half. This is the Bitcoin halving - and it’s the single most predictable, repeatable event in all of crypto. If you’ve ever wondered why Bitcoin prices seem to spike years after a halving, this is why.

Halving isn’t a marketing stunt. It’s baked into Bitcoin’s code. Satoshi Nakamoto designed it this way: every 210,000 blocks - roughly every four years - the reward miners get for securing the network drops by 50%. It’s not optional. It’s math. And it’s been happening without fail since 2012. The last one? April 20, 2024. The next? Around April 2028. What happens in between? Price. Always price.

How Halving Works - Simple

Miners use powerful computers to verify Bitcoin transactions and bundle them into blocks. For their work, they get paid in two ways: a block reward (newly created bitcoins) and transaction fees. The block reward is what halving changes. Before 2024, miners got 6.25 BTC per block. After April 20, 2024, they got 3.125 BTC. That’s it. No more. No less. The total supply of Bitcoin is capped at 21 million. Halving ensures we don’t reach that cap too fast. By 2140, no new bitcoins will be created. Only fees will pay miners.

This isn’t inflation. It’s the opposite. Fiat money? Central banks can print more anytime. Bitcoin? The supply growth rate drops by half every four years. Less supply entering the market, while demand stays steady or grows - that’s classic economics. And history shows it works.

The Four Halvings - What Actually Happened

Let’s look at the real data. Not guesses. Not predictions. What happened after each event.

• 2012 - First Halving: Block reward dropped from 50 to 25 BTC. Bitcoin was trading at $12. By April 2013? $229. By November? Over $1,100. A 1,800% gain in five months.
• 2016 - Second Halving: Reward fell from 25 to 12.5 BTC. Price was $640. By the end of 2017? Nearly $20,000. That’s a 3,000% rise from halving day.
• 2020 - Third Halving: Reward cut to 6.25 BTC. Price was around $9,000. Within 180 days? $14,849. By December 2021? Over $60,000. Even during a global pandemic, Bitcoin surged.
• 2024 - Fourth Halving: Reward now 3.125 BTC. Price hit $73,750 just before the event, dipped to $63,000 on halving day, then climbed again. By late 2025, it was consistently above $90,000.

Notice a pattern? Each time, the price didn’t jump right away. It took months - sometimes over a year. But every single halving was followed by a major bull run. Not once has Bitcoin gone down long-term after a halving.

Why Does Price Go Up After Halving?

It’s not magic. It’s supply and demand.

Before halving, miners were getting, say, 6.25 BTC per block. After? 3.125. That means half as many new bitcoins enter circulation every ten minutes. If people still want to buy Bitcoin - and they do - but fewer coins are being created, the price has to rise to balance the market.

Think of it like oil. If a major oil producer suddenly cuts output by 50%, and global demand stays the same, prices go up. Bitcoin works the same way. The halving is a supply shock - but a planned one.

There’s also psychology. Every halving gets covered by mainstream media. Retail investors notice. Institutions start buying ahead of time. The "fear and greed index" consistently spikes into "greed" territory in the 6-12 months after a halving. That’s not random. It’s expectation.

What About Miners? Do They Go Broke?

Short-term? Yes, some do. When the block reward drops, miners with older, inefficient hardware suddenly lose money. Their electricity costs exceed what they earn. Many shut down. The Bitcoin network’s hash rate - the total computing power - dips for a few weeks.

But here’s what happens next: Bitcoin’s price rises. And when it does, mining becomes profitable again. The miners who stayed in - the ones with cheap power and modern ASICs - start making more. The network’s hash rate rebounds, often stronger than before. This cycle has repeated four times. It’s not a bug. It’s a feature.

Post-2024, we saw something new: transaction fees jumped. On halving day, fees in the first block exceeded $2.6 million - six times higher than usual. Why? Because investors wanted their transactions confirmed in the historic block. That’s a sign of a maturing market. Miners aren’t just relying on block rewards anymore. Fees are becoming a real income stream.

The 2024 Halving - Different This Time?

Yes. And no.

Before 2024, Bitcoin was already a $1 trillion asset. ETFs were approved in the U.S. Institutions like Fidelity and BlackRock were buying. The market wasn’t driven by hobbyists anymore. It was driven by portfolio managers.

Because of that, the price didn’t explode the day after halving. It was already priced in. The $73,750 peak before the event meant traders had already bet on the rally. The immediate drop to $63,000? That was just profit-taking.

But the long-term trend? Still up. By August 2025, Bitcoin hit $102,000. By December? $118,000. Analysts who expected a 12-18 month rally were right. The pattern held - just smoother.

The big difference now? Bitcoin isn’t just a speculative asset. It’s a macro hedge. When inflation spiked in 2022-2023, Bitcoin outperformed gold, stocks, and even real estate. Halving reinforces that story: limited supply, no central authority, immune to printing.

What Comes Next? The 2028 Halving and Beyond

The next halving is expected in April 2028. By then, the block reward will drop to 1.5625 BTC. That’s less than 1% of Bitcoin’s original supply rate. The total supply in circulation? Over 19 million. Only 2 million left to mine.

By 2032? The reward drops again to 0.78125 BTC. That’s a 99.8% reduction from the original 50 BTC per block.

What does this mean? Bitcoin becomes scarcer than gold. Gold mines about 3,000 tons per year. Bitcoin will be producing less than 100 new coins per day by 2030. And those coins? They’ll be paid almost entirely in fees - not new supply.

Price targets? Analysts are already modeling $160,000-$200,000 by 2029. Some say $500,000 by 2035. It’s speculative - but the math doesn’t lie. With fewer new coins, and growing demand from global savings, the pressure on price is structural.

What Should You Do?

Don’t try to time the halving. You can’t. The market prices it in months ahead. Instead, understand the pattern:

• Halving = supply cut. Not a trigger. A slow-burning fuse.
• Price doesn’t spike immediately. Wait 6-18 months.
• Miners adapt. The network gets stronger.
• Every halving has been followed by a new all-time high.

If you’re holding Bitcoin, don’t panic during dips after a halving. That’s normal. The real move comes later. If you’re thinking of buying, don’t wait for the next halving. Wait for the next dip after it.

Bitcoin’s value isn’t built on hype. It’s built on code. And that code says: less supply, over time, with demand growing. That’s not speculation. That’s economics.
