What Is Bitcoin Halving?
Bitcoin halving is a major event that happens roughly every four years. It cuts the reward that miners get for creating new Bitcoin blocks by 50%.
This means fewer new bitcoins are released into the market, which increases scarcity. And when something becomes more scarce, its price can go up—if demand stays the same.
Bitcoin runs on a blockchain, which is a kind of digital ledger. Every time a new block of transactions is added to this ledger, miners compete to solve a complex math problem. The first one to solve it gets to add the block and earns a reward in the form of new bitcoins.
Once a block is added, the process starts again. But with each halving event, the reward gets smaller—meaning miners get fewer bitcoins than before for the same work.
Key Points to Remember
- Bitcoin halving occurs once every four years.
- Each halving reduces the number of new bitcoins created, which lowers the supply.
- The most recent halving took place on April 20, 2024, reducing rewards to 3.125 BTC per block.
- The final halving is expected in the year 2140 when Bitcoin’s supply reaches its cap of 21 million coins.
Is Bitcoin Halving Good or Bad?
It depends on who you ask. Many people see halving as a positive thing for Bitcoin’s future. Others see it as a challenge.
Controlling Inflation
One of the main reasons Bitcoin goes through halving events is to keep inflation in check. Inflation happens when money loses value over time, usually because too much of it is in circulation. Most central banks aim for a 2% inflation rate to keep economies stable.
Bitcoin’s halving helps fight inflation by keeping its supply limited. However, this protection only applies to Bitcoin itself—not the fiat currency (like US dollars or Kenyan shillings) you have to convert it into. So while Bitcoin may rise in value over time, it doesn’t shield users from the inflation of traditional currencies.
Demand Rises, So Might the Price
Since halving reduces the supply of new bitcoins, it often leads to an increase in demand. Historically, Bitcoin’s price has gone up after past halving events. That’s why many investors get excited when a halving approaches—they’re hoping the price will spike again.
Bitcoin as an Investment
Originally, Bitcoin was designed to be used like digital cash—a decentralized payment system without middlemen like banks. But over time, people began seeing it as a kind of digital gold, useful for storing value and making profits.
Because halvings reduce the new supply, investors hope they’ll push the price higher. This makes Bitcoin more of a speculative investment, where people buy it hoping its value will increase in the future.
Impact on Bitcoin Miners
Miners are the people and companies that use powerful computers to mine new bitcoins. As the reward gets cut in half, mining becomes less profitable—unless Bitcoin’s price rises sharply.
Running a mining operation isn’t cheap. It involves high electricity costs, expensive equipment, and constant upgrades.
Large mining companies like Marathon Digital Holdings invest heavily to stay ahead. For example, by early 2024, Marathon had expanded its mining fleet to 231,000 machines and held nearly 17,000 bitcoins. Its network power made up around 5% of the total Bitcoin mining power.
These upgrades were likely in preparation for the 2024 halving. As rewards drop, mining becomes more competitive. Smaller miners may find it difficult to keep up and could be pushed out or absorbed by larger players. Even if prices rise, rewards for smaller mining pools will be less than before.
Everyday Bitcoin Users
For regular users who buy Bitcoin to shop, save, or send money across borders, the impact of halving depends on Bitcoin’s price. If it goes up, the value of what they hold increases. If it goes down, their purchasing power shrinks.
For example, someone using Bitcoin for remittances will find that the amount their family receives can vary depending on the market price after halving.
When Will the Next Bitcoin Halving Happen?
The next halving is expected in 2028. After that, the block reward will be reduced again—from 3.125 BTC to just 1.5625 BTC.
Here’s a quick look at past Bitcoin halving dates and rewards:
- Nov. 28, 2012 – Reward cut from 50 BTC to 25 BTC
- July 9, 2016 – Cut from 25 BTC to 12.5 BTC
- May 11, 2020 – Cut from 12.5 BTC to 6.25 BTC
- April 20, 2024 – Cut from 6.25 BTC to 3.125 BTC
By May 2024, about 19.7 million bitcoins had already been mined, leaving only around 1.3 million left to be issued in the future.
Should You Buy Bitcoin During a Halving?
Many investors believe that halving leads to price increases, and history does support that view—although price changes usually happen gradually over time, not instantly. That said, no one can predict the market with 100% certainty.
The most recent halving in 2024 was different from past ones. It followed the approval of spot Bitcoin ETFs (Exchange-Traded Funds) by the U.S. SEC, which drew huge attention from investors. Many people switched from older Bitcoin trusts to these new ETFs.
A month after the halving, Bitcoin prices dropped, and ETFs saw massive withdrawals. But by mid-May, the market grew more optimistic again—especially around Ethereum ETFs—and Bitcoin’s price shot back up. This shows just how unpredictable the crypto market can be.
In short, whether you should invest before, during, or after a halving depends on your personal financial goals, how much risk you can handle, and how closely you watch market trends.
Frequently Asked Questions
What Happens During a Bitcoin Halving?
The amount of bitcoins miners receive for adding a block to the blockchain is reduced by half. This slows down the rate at which new bitcoins enter circulation, increases scarcity, and can push prices up if demand remains strong.
What Are the Dates of Bitcoin Halvings?
So far, Bitcoin has halved on the following dates:
- Nov. 28, 2012
- July 9, 2016
- May 11, 2020
- April 20, 2024
The next one is expected in mid-2028.
What Time Was the 2024 Halving?
The 2024 halving occurred on April 20, 2024, when Bitcoin block number 840,000 was mined.
How Many More Bitcoin Halvings Are Left?
There are expected to be 29 more halvings before the final one occurs around the year 2140. Eventually, the reward will be reduced to the smallest possible unit of Bitcoin—a satoshi (0.00000001 BTC). At that point, no more new bitcoins will be created.
Final Thoughts
Bitcoin halving is one of the most important features of how Bitcoin works. It slows down how many new coins are released, which helps keep the currency scarce and potentially valuable. This process will continue until the very last bitcoin is mined in 2140.
The block reward started at 50 BTC in 2009 and has dropped every four years. As of 2024, it’s down to 3.125 BTC. For miners, this may mean higher competition and more costs, especially for smaller operations. For investors, halvings represent opportunities—but also risks.
As always, anyone considering investing in Bitcoin should do their own research, understand the risks involved, and never invest more than they can afford to lose.
