Bitcoin Halving: When Will Bitcoin Next Halve?
Find out what Bitcoin halving is and what it means for the price & future of Bitcoin in our complete guide to Bitcoin halving. ✂
Bitcoin last halved in April 2024 from 6.25 BTC to 3.125 BTC.
The next estimated Bitcoin halving date will occur in 2028 when Bitcoin will halve to 1.5625.
Bitcoin halving is a formula into the blockchain that dictates that as the supply of Bitcoin decreases, the rewards for mining Bitcoin will decrease with it.
What is Bitcoin halving?
Bitcoin halving refers to the automated process which halves Bitcoin rewards for Bitcoin miners, approximately every four years, or every 210,000 blocks.
To fully understand why Bitcoin halves, the benefits, and what it means for Bitcoin there are a couple of key concepts we need to cover first.
Bitcoin key concepts
Bitcoin is a proof-of-work blockchain. This means Bitcoin miners solve complex mathematical puzzles in order to validate transactions and create new blocks on the Bitcoin blockchain. They’re rewarded for doing so in Bitcoin.
As well as this, Bitcoin has a fixed supply. This means there will only ever be a given number of Bitcoin in circulation - specifically, 21 million. At the time of writing, there are 20 million Bitcoin in circulation - leaving around 1 million Bitcoin left to mine.
Bitcoin halving was written into Bitcoin's mining algorithm to maintain scarcity and increase value. Every 210,000 blocks, the rewards Bitcoin miners receive for mining Bitcoins are halved - so miners receive 50% less for verifying Bitcoin transactions after each Bitcoin halving.
Why does Bitcoin halve?
At a basic level, Bitcoin halving makes Bitcoin more scarce and, theoretically, therefore more valuable. So the reward is halved, the inflation is halved, there's a lower available supply, and therefore higher demand and a higher price. This helps Bitcoin miners remain incentivized to mine, as although the rewards are smaller, the value of Bitcoin is higher.
If you’re asking why the Bitcoin halving formula was coded into the Bitcoin circulation process, we can go straight to the source instead: Bitcoin creator(s), Satoshi Nakamoto.
In the Bitcoin white paper, Nakamoto summarized their reasons for adding a constant rate formula;
"As computers get faster and the total computing power applied to creating Bitcoins increases, the difficulty increases proportionally to keep the total new production constant. Thus, it is known in advance how many new Bitcoins will be created every year in the future.
The fact that new coins are produced means the money supply increases by a planned amount, but this does not necessarily result in inflation. If the supply of money increases at the same rate that the number of people using it increases, prices remain stable. If it does not increase as fast as demand, there will be deflation, and early holders of money will see its value increase.
Coins have to get initially distributed somehow, and a constant rate seems like the best formula."
When did Bitcoin last halve?
Bitcoin last halved on April 19, 2024. The block reward was halved from 6.25 BTC to 3.125 BTC.
What is the Bitcoin block reward in 2026?
The current block reward for Bitcoin is 3.125 BTC and will remain this amount until the next Bitcoin halving.
When is the next Bitcoin halving date?
Bitcoin is likely to next halve in April, 2028, from 3.125 BTC to 1.562 BTC. See the estimated Bitcoin halving schedule below.
Bitcoin halving dates schedule
| Bitcoin Halving Event | Block Height | Block Reward | Date |
|---|---|---|---|
| Genesis block | 1 | 50 | January 9, 2009 |
| First Halving | 210,000 | 25 | November 28, 2012 |
| Second Halving | 420,000 | 12.5 | July 9, 2016 |
| Third Halving | 630,000 | 6.25 | May 11, 2020 |
| Fourth Halving | 840,000 | 3.125 | 19 April 2024 |
| Fifth Halving | 1,050,000 | 1.5625 | April 2028 (TBC) |
| Sixth Halving | 1,260,000 | 0.78125 | 2032 |
| Seventh Halving | 1,470,000 | 0.390625 | 2036 |
As you can see Bitcoin halves roughly every four years and the most recent Bitcoin halving (the fourth halving) took place on April 19, 2024, where the rewards halved from 6.25 BTC to 3.125 BTC.
Why are Bitcoin halvings happening less than every four years?
As you can see from previous Bitcoin halving dates, the four-year rule isn’t exact, and future Bitcoin halving dates are estimated dates. This is because Bitcoin halving isn’t scheduled to happen on a specific date every four years, instead, Bitcoin halves every 210,000 blocks and how fast that happens may vary slightly.
This all comes down to how the Bitcoin mining algorithm works. As dictated by the mining algorithm, each block should take 10 minutes to mine.
Of course, if more miners join the Bitcoin network and add more hashing power, without any other processes in place, the time to mine a block will decrease.
To stop this, the mining difficulty for Bitcoin resets every two weeks to maintain this 10-minute target. The more miners, the harder it is to mine a block, and vice versa.
Because of this formula, the exact date and time of the next Bitcoin halving can be difficult to estimate as sometimes the Bitcoin block time is slightly above or below the 10-minute target, and therefore 210,000 blocks may be mined marginally quicker (or slower) than every four years precisely.
Will Bitcoin go up or down after halving?
After past Bitcoin halvings, Bitcoin halving events have historically resulted in a rise in Bitcoin price, often several months prior in anticipation of the halving event.
Looking at historical data, we can see Bitcoin previously surged in price prior to a halving and has a large drop following the halving. Despite the drop, the price of Bitcoin has generally remained higher than the price prior to the halving event.
Of course, past performance does not indicate future results when it comes to crypto. The Bitcoin price may vary significantly before and after halving events, ultimately impacting the price effect of a Bitcoin halving event. However, the basic underlying economic theory here is that as supply decreases, demand increases.
Additionally, halving the block reward doubles the cost to miners, causing them to adjust their selling price to cover their mining costs, which could have a positive impact on price.
Should I sell my Bitcoin before halving?
Historically, halving has created some price volatility in the short term for Bitcoin, followed by a price rise shortly after. After the halving event, it may be harder to buy your Bitcoin back as supply will have been reduced slightly and therefore there may be increased demand.

When is the last Bitcoin halving?
The final Bitcoin halving event is estimated to happen in 2140. At this point, there will be 21 million Bitcoin in circulation and no more Bitcoin will be created through mining.
What happens after the last Bitcoin halving?
Bitcoin halving will cease when there is no more Bitcoin left to mine. Miners will only be rewarded with transaction fees instead.

Bitcoin Halving FAQs
When was the first Bitcoin halving?
The first Bitcoin halving happened in 2012. Bitcoin block rewards were cut from 50 BTC to 25 BTC - although at the time the price of BTC was far lower than it is today!
How can I trade over the course of Bitcoin halving?
You can trade as you normally would during Bitcoin halving events. If you'd like to make the most of the Bitcoin halving event, you can strategize when to buy and sell Bitcoin around the event, or even look at CFDs. This said you should do a lot of research first before you dive into these markets as these are extremely high risk. You can learn more in our crypto derivatives guide and crypto options guide.
Is Bitcoin halving bad?
Miners may see Bitcoin mining as bad in the short-term as their rewards are reduced, however, Bitcoin halving has benefits. Historically, the price of Bitcoin has risen and remained higher after halving events.
Can I make money from the Bitcoin halving?
Sure, in theory, if you buy and sell at opportune moments during the run-up to and following the Bitcoin halving event you may be able to get some gains. You can do your research and look at a variety of technical indicators to strategize. But don’t forget, the taxman will want his cut!
Will Bitcoin ever stop halving?
Yes. When there are 21 million Bitcoin in circulation and no Bitcoin left to mine, Bitcoin will stop halving. Don’t worry though, this isn’t due to occur until 2140 according to current predictions!
What happens to my Bitcoin after halving?
Nothing happens to Bitcoin you own after halving, only Bitcoin miners are impacted. They’ll receive half the block rewards than they previously did after a Bitcoin halving event. This said, there are often large price fluctuations around Bitcoin halving events historically.
Does halving increase crypto price?
Theoretically, yes. The economic theory here is that having a capped supply of a given cryptocurrency increases its scarcity. As the crypto becomes more scarce, supply decreases, and demand increases. It should go without saying that this is all in theory. The crypto market is unpredictable and past performance does not predict future results.
When will all Bitcoin be mined?
All Bitcoin will be mined when there are 21 million Bitcoin in circulation. This is estimated to occur in 2140 currently.
