What is a Bitcoin halving?

Bitpanda Academy Bitcoin Halving

In a Bitcoin halving, the network halves the number of new Bitcoin miners receive as a reward for adding a block. This event occurs after every 210,000 blocks mined – roughly every four years. This allows the network to control the money supply and ensures that no more than 21 million Bitcoin will ever be in circulation.

The most recent halving took place in April 2024. Since then, miners no longer receive 6.25 BTC but only 3.125 BTC per block. Whether you’re a beginner or an experienced crypto trader, Bitcoin halving is one of the most important concepts in the crypto market. We’ll explain what it is and why Bitcoin halving matters to you as a trader.

  • What does Bitcoin halving mean: About every four years, the Bitcoin network automatically halves the block reward for miners, reducing the issuance of new BTC and tightening supply.

  • What happens during Bitcoin halving: The reward for mining a block drops by exactly 50%, reducing inflation and increasing Bitcoin scarcity.

  • When was the last Bitcoin halving: In April 2024, the fourth halving in Bitcoin’s history, the reward was halved from 6.25 to 3.125 BTC per block.

What is the next Bitcoin halving: The next halving is expected in 2028, when the block reward will drop further to 1.5625 BTC.

How does Bitcoin halving work?

Bitcoin halving is a mechanism in the network that ensures a controlled release of new BTC. Here’s how the process works:

  • Mining and block reward: Miners verify transactions and add new blocks to the blockchain and are rewarded with newly minted Bitcoin.

  • Fixed number of blocks: every 210,000 blocks, roughly every four years, the network automatically reduces the block reward.

  • Reduction of the reward: with each halving, the reward per block drops by 50%.

  • Artificial scarcity: halving slows the rate at which new BTC enter circulation, gradually increasing scarcity.

When was the last Bitcoin halving?

The most recent Bitcoin halving took place in April 2024. It was the fourth halving since the Bitcoin network began and, like all previous ones, is hardcoded into the Bitcoin protocol.

Earlier halvings took place in 2012, 2016 and 2020. Each of these events had noticeable effects on the block reward, miner incentives and market trajectory.

When is the next Bitcoin halving?

The next Bitcoin halving is expected to occur in 2028, once the blockchain reaches a height of 1,050,000 blocks. Since the event isn’t tied to a fixed date, the exact timing can only be estimated.

The current hashrate affects how quickly new blocks are mined. Tools continuously recalculate the likely date. In the next halving, the block reward will fall from 3.125 BTC to 1.5625 BTC.

Why is Bitcoin halving important?

Bitcoin halving affects how new BTC are created, how the network functions and how the supply develops over time. It’s a core part of the Bitcoin protocol and serves several key functions.

Here’s why Bitcoin halving matters to you as an investor:

  • Limited supply: By halving the block reward, fewer new Bitcoin enter circulation, creating artificial scarcity.

  • Protection against inflation: Regular halving limits the issuance of new BTC and protects the cryptocurrency from inflation, unlike fiat currencies with flexible supply.

  • Incentives for miners: The reward motivates miners to contribute computing power and secure the network, reinforcing the security of the proof-of-work mechanism.

  • Market impact: Previous halvings have had noticeable effects on price trends and market behaviour.

  • Predictable monetary policy: Halvings are coded in, creating predictability and trust in Bitcoin’s long-term structure.

Market impact of the Bitcoin halving

The Bitcoin halving changes the balance of supply and demand in the BTC network. With each halving, the number of newly mined Bitcoin decreases, which leads to a reduced inflation rate and increased scarcity.

These changes affect the market:

  • Expectations before the halving: Many investors expect a long-term price increase and position themselves early before the halving.

  • Increased market volatility: Around the halving, price movements and thus fluctuating prices often increase, driven by speculative behaviour of many investors.

  • Impact on digital assets: As the leading currency among cryptocurrencies, BTC also affects the price of other coins and tokens.

  • Relevance for ETFs and certificates: Products like Bitcoin ETFs or crypto certificates track the BTC price and react accordingly to market changes.

Impact of the Bitcoin halving on the Bitcoin price

The Bitcoin halving affects the price of BTC because it reduces supply and alters market expectations. These effects become more pronounced before and after the Bitcoin halving.

Typical price effects include:

  • Before the halving: The expectation of rising prices often leads to early purchases and price increases.

  • After the halving: The reduced issuance of new BTC limits supply and can either stabilise or increase the price.

  • Short-term volatility: Price movements around the halving are often more intense than during normal periods.

  • Long-term upward trend: Previous halvings were in many cases followed by longer-term price increases.

  • Psychological effect: The artificial scarcity reinforces Bitcoin’s image as a scarce asset and generally has a positive impact on price formation.

Impact of the Bitcoin halving on miners

Since the last halving in April 2024, the block reward has been 3.125 BTC per block. This significantly reduces miners’ income, while ongoing costs for electricity and hardware remain unchanged. Some respond by reducing their activity or switching to other networks.

The speed of block creation remains unaffected. The Bitcoin protocol automatically adjusts mining difficulty based on the current hashrate. As a result, a new block is still created on average every ten minutes and the network generally remains stable. Some miners adjust their strategies in advance of a halving, in the expectation that the reduced issuance of BTC could affect the price in the medium term.

What impact has the Bitcoin halving had in the past?

Looking back, it’s clear that every Bitcoin halving has had a noticeable impact on the network and the market. The halving of the block reward reduces the supply of new BTC and changes the dynamic between supply and demand, with consequences for price, Bitcoin mining and market behaviour.

Past short- and medium-term effects

  • In the weeks leading up to a halving, interest increased significantly, as many investors bet on a long-term price rise.

  • Shortly after the event, volatility often increased, triggered by speculation and new market positions.

  • In the medium term, every halving was so far followed by strong price increases: in 2012 to over $1,000, in 2016 to nearly $20,000 and in 2020 to over $60,000 by the end of 2021.

Past effects on supply and demand

  • With each halving, the block reward decreased, resulting in fewer new BTC entering circulation.

  • In several cases, rising demand became apparent, especially during the price surges after 2012, 2016 and 2020.

  • Many market observers increasingly interpreted Bitcoin during these phases as a deflationary cryptocurrency with the characteristics of a digital store of value.

  • The halvings regularly intensified speculative behaviour and influenced market expectations.

  • Media attention around past halvings temporarily raised Bitcoin’s profile as a cryptocurrency in public awareness.

Past effects on miners

  • The reduced reward forced miners to reassess their operating costs and profitability.

  • Less efficient miners often withdrew from the network in the past.

  • At the same time, stronger miners held their ground and contributed to network stability.

  • The hashrate showed temporary fluctuations after previous halvings, but stabilised thanks to automatic difficulty adjustments.

What happens when the last Bitcoin is mined?

Once the final Bitcoin has been created – expected around the year 2140 – the issuance of new BTC will end. The network will remain active, as miners will then receive their compensation solely through transaction fees that users pay for Bitcoin transactions.

Until then, each halving gradually reduces the block reward until no new BTC are created. But even without block rewards, miners will continue to secure the network, validate transactions and receive fees for doing so. This means Bitcoin will remain permanently deflationary and technically functional, even without new coins.
