Bitcoin halving is a built-in event, roughly every four years, when the reward paid to Bitcoin miners for each new block is cut in half. The last halving was on 20 April 2024, when the reward fell from 6.25 to 3.125 Bitcoin per block, and the next halving is expected around April 2028, when the reward will fall again to 1.5625 Bitcoin per block.
Key points:
- Halving cuts the new Bitcoin miners earn by half, every 210,000 blocks — roughly every four years.
- The last halving was in April 2024 (reward now 3.125 BTC per block); the next is expected around April 2028.
- Halving slows how fast new Bitcoin is created, which is how Bitcoin keeps its total supply capped at 21 million coins.
What does halving actually mean in simple words?
Think of Bitcoin miners as workers who keep the network running. A miner is a powerful computer that checks transactions and groups them into a block — a page of records added to Bitcoin's public record book, called the blockchain. As a payment for that work, the miner receives brand-new Bitcoin. That payment is called the block reward. A halving simply means that payment is cut by 50 percent, and it stays at the new lower level until the next halving about four years later. Nothing happens to coins people already own — only the flow of new coins slows down.
Why does Bitcoin have halvings at all?
Bitcoin was designed to be scarce, the opposite of normal money that a government can print in unlimited amounts. Its creator set two clear rules: there will never be more than 21 million Bitcoin in total, and the reward for miners will keep halving until that limit is nearly reached. Slowing the supply of new coins over time is meant to control inflation — the slow loss of buying power that happens when too much new money is created too fast. Because the halving rule is written into Bitcoin's code and agreed by the whole network, no person, company or government can change it on their own.
When were the past Bitcoin halvings?
There have been four halvings so far. The first was in November 2012, when the reward fell from 50 to 25 Bitcoin per block. The second was in July 2016, from 25 to 12.5. The third was in May 2020, from 12.5 to 6.25. The fourth and most recent was on 20 April 2024, from 6.25 to 3.125, at block number 840,000. Each step follows the same pattern: every 210,000 blocks, the reward is cut in half, exactly as the code has planned since Bitcoin started in 2009.

When is the next Bitcoin halving?
The next halving is expected around April 2028, when the blockchain reaches block number 1,050,000. At that point the block reward will fall from 3.125 to 1.5625 Bitcoin per block, so the amount of new Bitcoin created each day will drop from roughly 450 coins to roughly 225 coins. The exact calendar date is not fixed, because a halving is triggered by a block number, not by a date. Blocks are found roughly every ten minutes, but not exactly, so the April 2028 timing is a careful estimate that can shift by days or weeks as it gets closer.
What happens to miners when the halving comes?
Miners earn the block reward plus small fees that users pay to send Bitcoin. When the reward halves, a miner's main income halves overnight, while bills for electricity and machines stay the same. Efficient miners with cheap power usually keep going, while miners with old machines or high power costs may switch off or upgrade. This is normal and has happened at every halving. The network adjusts itself automatically — if some miners leave, the puzzle that miners solve becomes a little easier, so blocks keep coming about every ten minutes.
Does halving make the Bitcoin price go up?
Nobody can promise that. It is true that in past cycles the price often rose in the months before and after a halving, and many people link that to the slower supply of new coins. But the price also depends on many other things at the same time — the world economy, interest rates, new rules and laws, and how much buyers and sellers want Bitcoin that month. Past behaviour is not a promise of what will happen next time, so a halving should be understood as a supply event, not a price guarantee.
What happens when all 21 million Bitcoin are mined?
Because the reward keeps halving, the very last small pieces of Bitcoin are expected to be mined around the year 2140 — more than a hundred years from now. After that, no new Bitcoin will be created at all. Miners will still be paid, but only from the transaction fees users pay, instead of from new coins. Until then, each halving takes Bitcoin one step closer to its fixed 21 million limit, which is a big part of why many people describe Bitcoin as scarce, like a digital form of gold.
