When Bitcoin's Last Halving Happened and What It Means

The most recent Bitcoin halving occurred on April 19, 2024

Bitcoin's last halving took place on April 19, 2024, at block 840,000. At that moment, the reward miners receive for validating transactions dropped from 6.25 BTC to 3.125 BTC per block. This was the fourth halving in Bitcoin's history since the network launched in 2009.

Halvings happen automatically every 210,000 blocks, which occurs roughly every four years. The next halving is expected around 2028, though the exact date depends on how fast miners process blocks. Bitcoin's code was designed to cut the mining reward in half repeatedly until the supply reaches its maximum of 21 million coins, which is expected to happen sometime in the year 2140.

Key Takeaways

• The April 19, 2024 halving reduced the mining reward from 6.25 BTC to 3.125 BTC per block mined.
• Halvings occur every 210,000 blocks, roughly every four years, and are built into Bitcoin's code.
• After each halving, fewer new bitcoins enter circulation, which affects the rate at which the total supply grows.
• The halving does not change how Bitcoin works for ordinary users — it only affects miners and the pace of new coin creation.

Why halvings happen and how they work

Bitcoin's creator designed the network to release new coins at a declining rate. When Bitcoin launched in 2009, miners earned 50 BTC per block. Every 210,000 blocks, that reward is cut in half. This schedule is written into Bitcoin's code and happens automatically — no person or organization decides when it occurs.

The halving serves two purposes. First, it controls inflation by slowing the rate at which new bitcoins are created. Second, it ensures that the total supply will never exceed 21 million coins. Once all coins are mined, miners will earn money only from transaction fees, not from newly created bitcoins.

A timeline of Bitcoin halvings

Halving Number	Date	Block Height	Reward Before	Reward After
First	November 28, 2012	210,000	50 BTC	25 BTC
Second	July 9, 2016	420,000	25 BTC	12.5 BTC
Third	May 11, 2020	630,000	12.5 BTC	6.25 BTC
Fourth	April 19, 2024	840,000	6.25 BTC	3.125 BTC

The time between halvings varies slightly because block processing speed is not perfectly constant. The network adjusts mining difficulty every 2,016 blocks to keep the average block time at 10 minutes, but real-world conditions mean some halvings occur a few days earlier or later than the four-year estimate.

What changed after the April 2024 halving

After April 19, 2024, the amount of new bitcoin created each day dropped by half. Before the halving, approximately 900 BTC entered circulation daily. After the halving, that number fell to about 450 BTC per day. This reduction affects the rate at which the total supply grows, but it does not change how Bitcoin functions for people who own or use it.

For miners, the halving means they earn half as much in newly created coins per block they mine. Some miners with higher operating costs may find mining less profitable and shut down their operations. Others may continue mining if they have access to cheap electricity or newer, more efficient equipment.

How the halving affects Bitcoin's price

Halvings are often discussed in relation to Bitcoin's price, but the relationship is not direct or may provide. Some people believe that reducing the supply of new coins should push the price higher over time, since scarcity increases. Others point out that Bitcoin's price is driven by many factors — demand from buyers and sellers, news events, macroeconomic conditions, and regulatory changes.

Historical data shows that Bitcoin's price has risen significantly in the years following past halvings, but it has also fallen during those same periods. The halving itself is predictable and known in advance, so traders and investors have already factored it into their decisions before it occurs. Whether the price rises or falls after a halving depends on what happens in the broader market, not on the halving event alone.

When to expect the next halving

The fifth halving is expected to occur around 2028, when the network reaches block 1,050,000. At that point, the mining reward will drop from 3.125 BTC to approximately 1.5625 BTC per block. The exact date will depend on how quickly miners process blocks over the next four years.

You can track the progress toward the next halving on blockchain explorers and Bitcoin information websites, which show the current block height and estimate how many blocks remain. Since each block takes roughly 10 minutes to mine, you can calculate an approximate date, though the actual halving may occur a few days earlier or later.

Frequently Asked Questions

Does the halving affect my Bitcoin holdings?

No. The halving does not change the number of bitcoins you own or how you can use them. It only affects how many new bitcoins miners earn and how fast the total supply grows. Your wallet and your coins work exactly the same way before and after a halving.

Why does Bitcoin have a maximum supply of 21 million coins?

Bitcoin's creator built this limit into the code to create scarcity. Unlike government-issued money, which can be printed in unlimited quantities, Bitcoin's supply is fixed. The halving schedule ensures that the 21 million limit will be reached gradually, with the last bitcoin expected to be mined around the year 2140.

Can the halving schedule be changed?

Changing the halving schedule would require altering Bitcoin's core code and gaining agreement from the network's participants. This is theoretically possible but extremely difficult in practice, because Bitcoin is decentralized and no single person or group controls it. The halving schedule has remained unchanged since Bitcoin's launch.

What happens to miners after all 21 million bitcoins are mined?

Miners will continue to validate transactions and find the network, but they will earn money only from transaction fees, not from newly created bitcoins. The amount miners earn from fees depends on how many transactions occur and how much users are willing to pay to have their transactions processed quickly.
