Bitcoin Halving: How Does It Affect Bitcoin Mining


Bitcoin, the world’s first decentralized cryptocurrency, has revolutionized the financial landscape since its inception in 2009. At the heart of this digital currency lies a process called “Bitcoin mining,” which involves solving complex mathematical puzzles to validate transactions and secure the network. However, Bitcoin’s design incorporates a unique event called “Bitcoin halving,” which has a significant impact on the mining ecosystem.

As of 2023, network participants who validate transactions are awarded 6.25 bitcoins (BTC) for each block successfully mined.

The next halving is expected to occur in April or May 2024, when the block reward will fall to 3.125. Over time, the impact of each halving will diminish as the block reward approaches zero.

In this blog, we will delve into what Bitcoin halving is and explore its effects on Bitcoin mining with Antminer S19 ASICs.

What is Bitcoin Halving?

A “block” is a file containing 1 The blockchain for Bitcoin contains MB worth of transaction records in BTC. “Miners” compete to add the next block by solving a complex mathematical problem using specialized hardware, producing a random 64-character output known as a “hash,” finishing the process, and locking the block so it can’t be changed. Mines receive Bitcoin for completing these blocks.

Consequently, how does the Bitcoin halving cycle operate? When the cryptocurrency first started, miners received 50 BTC for each block they produced. In this way, even before it was clear the network would be successful, early users could be persuaded to mine it. Every 210,000 blocks that are mined, or roughly every four years until all 21 million Bitcoin have been mined, the rate at which new Bitcoin are created decreases by half.

The last three Bitcoin halves occurred in 2012, 2016, and 2020, according to the history of halving dates. In 2012, the reward for mining a block was decreased from 50 to 25 BTC, marking the beginning of the first Bitcoin halving or split.

Since the 2016 incentive halving event, which reduced rewards to 12.5 BTC for each block mined, each new block will only produce 6.25 BTC as of May 11, 2020. The following Bitcoin halving is anticipated to occur in 2024. Up until around 2140, this system will be in place.

Bitcoin Halving: How Does It Affect Bitcoin Mining

We’ll go over the history of Bitcoin halving, how it operates, and why it matters in this guide.

Why Does Bitcoin Halving Occur?

Every ten minutes, the Bitcoin mining algorithm is set up to search for fresh blocks. More miners joining the network and adding more hashing power will speed up the process of finding blocks. Approximately every two weeks, the mining difficulty is reset to restore a 10-minute objective. The average time to find a block has consistently been less than 10 minutes (roughly 9.5 minutes), despite the Bitcoin network’s explosive growth over the past ten years.

The total number of bitcoins available is 21 million. Once there are 21 million BTC in existence, new Bitcoin will no longer be created. Bitcoin halving ensures that as time goes on, the amount of Bitcoin that can be mined for each block decreases, increasing the rarity and value of BTC.

It makes sense that as each halving was finished, the incentive to mine bitcoin would decline. On the other hand, when the value of bitcoin is halved, it often results in a sharp rise in the price of BTC, which encourages miners to continue mining even though their rewards have been cut in half.

As the price of bitcoin rises, miners are urged to keep working. On the other hand, if Bitcoin’s value remains flat and block rewards are decreased, miners might lose their motivation to produce more of the digital currency. This is due to the fact that mining Bitcoin requires a lot of computer power and is an expensive, time-consuming process.

Why Does Bitcoin Halving Matter?

When Bitcoin’s value is halved, there is typically a lot of upheaval for the cryptocurrency. The halving cycle causes a reduction in the amount of Bitcoin that is readily available, increasing the value of unmined Bitcoin. And the chance to make money comes along with such changes.

The initial halving occurred on November 28, 2012, when BTC was trading at about $12; a year later, it had risen to almost $1,000. Bitcoin’s price fell to $670 on July 9, 2016, after the second halving, but by July 2017, it had risen to $2,550. In December of that year, Bitcoin surpassed its all-time high, which was roughly $19,700. The most recent halving occurred in May 2020, and at that time, the price of bitcoin was $8,787. In the months that followed, the price of bitcoin skyrocketed.

Of course, there were other elements to consider when analyzing Bitcoin’s post-halving booms:

  • The media should write more about Bitcoin and cryptocurrencies.
  • The anonymity of the digital asset has people fascinated.
  • an increase over time in the currency’s actual-world applications.

If you trust history, past Bitcoin price halvings have actually served as long-term bullish catalysts for the cryptocurrency. On the other hand, the third Bitcoin halving will almost certainly have an effect on the BTC ecosystem in a number of ways. Primarily, it is anticipated that there will be a decline in the number of Bitcoin miners as the financial incentive for mining diminishes and, for less skilled miners, becomes unprofitable.

The halving of Bitcoin frequently represents Bitcoin’s tendency toward deflation. The main argument in favor of Bitcoin has been that it is a decentralized cryptocurrency that cannot be created by governments or central banks, and that its total supply is fully known. This has been the case for Bitcoin ever since it first appeared.

How is Bitcoin Halving Correlated to Bitcoin Mining?

The quantity of newly issued bitcoins is reduced by half after every 210,000 blocks. Depending on the speed at which blocks are mined, which takes on average 10 minutes, this translates to roughly every four years.

The process of “mining”—which involves using specialized computers called Application-Specific Integrated Circuits (ASICs), or computers made to hash data as quickly as possible—adds blocks to the Bitcoin blockchain.

Without the interference of any centralized authority, mining is used to permanently add transactions to the blockchain. By using resources (mining), miners are rewarded with bitcoins for helping to secure the network.

Effects on Bitcoin Mining

  1. Reduced Supply: By lowering the supply of new Bitcoins entering circulation, the halving mechanism aims to control inflation. The rate at which new Bitcoins are created declines noticeably with each halving event. The increased demand caused by this scarcity factor frequently raises the price of Bitcoin.
  2. Mining Benefits: Bitcoin mining is a time- and energy-consuming process that necessitates specialized equipment. To compete for block rewards, miners make large equipment investments. In the event of a reward halving, miners’ profitability is directly impacted. For the same amount of computational work, miners receive fewer Bitcoins, which has a big impact on their income.
  3. Mining Difficulty: In order to maintain a consistent block time of about 10 minutes, the Bitcoin protocol modifies the mining difficulty roughly every two weeks or every 2016 blocks. Based on the network’s overall computational capacity, the adjustment is made. The overall mining hash rate may decrease as miners leave the network as a result of decreased profitability following a halving event. As a result, the protocol modifies the level of difficulty, making it simpler for the remaining miners to locate blocks.
  4. Events that cause the price of Bitcoin to halve frequently lead to hype and speculative activity in the cryptocurrency market. The halving is viewed as a significant event that could affect the price of Bitcoin, so traders, investors, and speculators keep a close eye on it. Market volatility and trading activity may increase in response to expectations of a reduced supply and potential price increase.

What If a Significant Number of Miners Abruptly Dropped Out of the Race?

We must first talk about hash rate in order to fully understand this. The number of SHA256 computing operations carried out each second is known as the hash rate in the context of Bitcoin mining. As the number of miners grows, this value rises, suggesting that the network is faster and more secure.

The network may temporarily bottleneck if a large number of miners decide to leave at once as users move to chains with higher throughput, making it easier for malicious users to seize control of sizable portions of the network.

Evidence from the past, however, indicates that this reaction is not brought on by events that are halved. From December 2012 to mid-February 2013, when the first halving took place, Bitcoin’s hash rate was somewhat lower. Following that, mining profitability as well as hash rate both rose. This indicates that, after all is said and done, halving is beneficial to both miners and the network as a whole.

The second Bitcoin halving had a similar outcome, but the positive effects took longer to materialize. Although the hash rate kept increasing steadily, mining profitability did not increase again for almost a year after the date of the halving. Mining profitability might experience a long-term decline if this pattern holds true for the upcoming event.

Does the Halving Affect Bitcoin’s Price?

BTC price can be affected by the halving as:

  • The halving of rewards encourages the network to grow healthily and sustainably. The halving guarantees that the supply of bitcoins remains constrained and finite, which can support the preservation of its value over time.
  • Following a halving, Bitcoin’s inflation rate declines, indicating a decrease in the number of new coins being introduced to the market.

Both participants and market analysts frequently disagree on this issue. Some predict that the price of Bitcoin will rise significantly as a result of the halving because the lower inflation rate will increase demand and value. Others contend that because the price of the halving has already been factored into the market, the event will not affect the price of the cryptocurrency.

Bitcoin Halving: How Does It Affect Bitcoin Mining

In the end, many different factors contribute to the price of Bitcoin. Among them are changes in regulatory requirements as well as market sentiment and demand. What effect the halving will have on its value is difficult to foresee.

History of Bitcoin Halving

There have been three halves of Bitcoin since its inception in 2009. Learn about previous times when the value of bitcoin has been halved, starting with the first instance in 2012.

2012 – This was the first halving in the history of the bitcoin network, and there were concerns about how the Satoshi halving economics would affect the development of bitcoin. Would it control inflation or spell its demise?

The Bitcoin block reward was halved on November 28, 2012, from 50 BTC to 25 BTC. After a year, the price of 1 BTC rose from $12 to approximately $1,031.95 (over 8,500%). By this time, 210,000 blocks had been created, and 10.5 million bitcoins, or half of the total supply, had been put into circulation.

2016 – The cryptocurrency community had been eagerly awaiting this second halving’s date. Additionally, before the July 9 halving date, investors’ acceptance and popularity of bitcoin increased, causing a brief price increase.

The bitcoin block reward decreased once more to 12.5 BTC with the mining of block number 420,000. At this moment, the price of one bitcoin was $650.96. The price of bitcoin was falling a few weeks after the halving. The price of one bitcoin reached an all-time high of $20,089 after 526 days since the halving, so this was only a retreat for an exponential rise.

2020 – The most recent halving, which is the third, took place amid a number of uncertainties, particularly as a result of the COVID-19 crisis, which contributed to the price collapse of bitcoin in March. But given that Bitcoin has been trending upward, Satoshi’s economic strategy is proving to be a brilliant one.

On May 11, the block reward was halved from 12.5 to 6.25 at the 630,000th block; at the time, the price of one bitcoin was approximately $8,787. 18 months from then At its peak, bitcoin was worth about $66,000.

The following halving is anticipated to take place in 2024 at block 840,000, where block rewards will be cut in half to 3.125 BTC.

When is the Next Bitcoin Halving Event?

Over 18.5 million, or almost 89%, of the 21 million BTC that could ever exist have been mined and are currently in use. Approximately 900 new Bitcoins are mined each day and added to the digital economy, though this number may be higher given that faster mining rates have led to higher mining rates.

The rate of Bitcoin supply growth will slow as halvings continue until all 21 million BTC have been mined; predictions place the final Bitcoin fractions’ mining in the year 2140.

No specific date has been set, but in the future the reward for mining a block will be cut in half once more. The solution will be made known once the 210,000th block has been mined since the previous halving.

Since a new Bitcoin is created every 10 minutes, the subsequent halving is most likely to take place in the early 2024; at that time, a miner’s payout will be reduced to 3.125 BTC.


In the ecosystem of cryptocurrencies, the halving of bitcoin is a crucial event. Every four years, the mining reward is reduced, which has a significant effect on both miners and the market as a whole. Bitcoin’s price may rise due to a decrease in supply and an increase in scarcity, and mining profitability may change as a result of decreasing rewards. Anyone working in the cryptocurrency industry must be aware of how the Bitcoin halving works and how it affects mining. The fascinating world of Bitcoin and its halving events is still being shaped by the interaction of mining economics, market dynamics, and technological advancements.


How Does the Halving Affect Bitcoin?

Historically, the price of bitcoin always rose significantly after a halving event, but not immediately. According to a close examination of the last three halving occasions, a significant price increase typically starts six to twelve months after the halving event.

What Will Happen After Bitcoin Halving in 2024?

Block rewards were first decreased from 50 BTC to 25 BTC, then from 25 to 12.5%, and finally from 12.5% to the current 6.25 BTC. This means that the cryptocurrency’s current inflation levels are under 2% and will go further down as the rewards will be 3.125 BTC after the 2024 halving.

Is Bitcoin Halving Good Or Bad?

Miners may see Bitcoin mining as bad in the short-term as their rewards are reduced, however, Bitcoin halving has benefits. After Bitcoin price halving events in the past, the price increased and stayed higher.

Is Bitcoin Halving Bullish Or Bearish?

In the past, halving has been viewed as a very positive sign for boosting Bitcoin’s price. So, if we closely observe the data, past Bitcoin halving events have been able to establish long-term bullish drivers for Bitcoin’s price.
