Intro to Bitcoin halvings
In the ever-evolving world of cryptocurrency, bitcoin halvings stand as predictable and reliable events.
With 36% of U.S. crypto holders seeing more growth potential for cryptocurrency than other asset classes, learning the history (and future) of bitcoin's halving cycle is important for any cryptocurrency investor.
A bitcoin halving refers to a predetermined event written into bitcoin's code that cuts the block reward, which is the incentive for miners to validate transactions and secure the network, in half about every four years.
This seemingly simple change triggers a ripple effect throughout the bitcoin ecosystem that impacts miners, investors and the overall market dynamics. By knowing more about past halving events and how they impacted bitcoin, investors can take a more informed and strategic approach to how they participate in the crypto economy.
Bitcoin halving timeline: 2012 and beyond
Bitcoin's halving events often spark interest among those who buy bitcoin and are involved in the Web3 space. While there isn’t a clear cause-and-effect relationship with price, analyzing past halvings and their corresponding market movements can reveal market trends.
Here's a timeline outlining the history of bitcoin halving events:
November 28, 2012, First Bitcoin halving: Reduced to 25 BTC
On November 28, 2012, the bitcoin network underwent its first programmed halving, roughly four years after the genesis block was mined. This milestone demonstrated the network's resilience and ability to adhere to the rules laid out in the protocol. This event reduced the block reward for miners from 50 BTC to 25 BTC.
While the impact of Bitcoin’s first halving on bitcoin’s price was being debated within the small but growing online community, the cryptocurrency remained largely obscure to the general public.
At this point, Bitcoin was primarily known only to a niche of early adopters, cryptographers, and economists. The concept of a decentralized digital currency was still largely theoretical and the network's infrastructure was in its infancy.
It's important to note that solely attributing bitcoin’s price increase (from absolutely nothing to something) to this first halving event is difficult. The cryptocurrency market was still in its early stages, and a variety of factors played a role in its steady growth in adoption over this time.
July 9, 2016, Second Bitcoin halving: Reduced to 12.5 BTC
The period between 2012 and 2016 was marked by significant growth in Bitcoin adoption. Early adopters and businesses began experimenting with Bitcoin payments and the ecosystem expanded to include digital wallets, exchanges and merchant services.
Despite its developmental stage, the price of bitcoin experienced growth following the first halving in 2012. From approximately $12 per coin in late 2012, the price surged to $229 by April 2013 and reached around $1,100 by November of the same year.
This growing recognition and acceptance contributed to bitcoin increasing legitimacy and viability. During this same halving period in 2015, Ethereum launched, introducing smart contracts and decentralized applications (dApps) to the blockchain ecosystem.
On July 9, 2016, bitcoin underwent its second halving, reducing the block reward from 25 BTC to 12.5 BTC. While still facing skepticism and regulatory uncertainty, it gained traction as a medium of exchange for various goods and services.
The price of bitcoin exhibited a short-term decline after the second halving, experiencing a roughly 40% decrease. Despite the initial price drop, the value of bitcoin experienced a significant increase in the following year and a half, reaching nearly $20,000 by the end of 2017.
May 11, 2020, Third Bitcoin halving: Reduced to 6.25 BTC
The period from 2016 to 2020 witnessed the cryptocurrency industry mature, with the concept of decentralization evolving from theory to practice. Bitcoin solidified its position as the leading cryptocurrency, while a diverse ecosystem of different types of cryptocurrency emerged.
Altcoins like Ethereum gained traction thanks to its smart contracts functionality. These allowed developers to program autonomous business logic that powered different types of decentralized applications (dApps). Memecoins emerged and topics like Dogecoin's price become pop cultural trends at this time, capturing the public's imagination and demonstrating the peer-to-peer ethos of cryptocurrency.
The third bitcoin halving on May 11, 2020, reduced the block reward from 12.5 BTC to 6.25 BTC. This event coincided with the onset of the COVID-19 pandemic, which created an unprecedented situation for analyzing market performance. Bitcoin's price experienced a significant decline, reflecting broader economic uncertainty of the time.
After the May halving, where bitcoin’s market price sat around $8,500, bitcoin's price rose steadily for the rest of 2020. By November 2021, bitcoin's price had peaked above $67,000, marking a nine-year journey since the first halving event in 2012.
April 20, 2024, Fourth Bitcoin halving: Reduced to 3.125 BTC
On April 20, 2024, bitcoin underwent its fourth programmed halving event. This code change cut the block from 6.25 BTC to 3.125 BTC per block, significantly decreasing the rate at which new bitcoin enters the market through the bitcoin mining process.
As the significance of bitcoin’s slowing inflation rate began to be truly understood, more people started considering bitcoin's relevance as a truly scarce asset.
The impact of this halving is still emerging. While the approval of Ethereum spot ETFs by the SEC shortly after this halving has opened crypto to new investors, the full impact of reduced rewards for miners remains to be seen. As the number of coins entering circulation through the mining process reduces to just three bitcoin, miners earn less reward for winning the already extremely challenging mining process.
While miners experience a direct impact on their revenue due to the reduced block reward, the broader market sentiment according to the so-called “fear and greed index” has remained largely optimistic about bitcoin's long-term prospects.
As the inflation rate of traditional currencies accelerated in many parts of the world in the wake of the pandemic, bitcoin's deflationary nature became increasingly attractive to investors seeking to hedge against economic uncertainty. While the immediate impact of the halving on Bitcoin's price was less pronounced than in previous cycles, the event contributed to the growing perception of bitcoin as a digital gold and provably scarce asset.
~ April 2028, Fifth Bitcoin halving: Reduced to 1.5625 BTC
The next anticipated bitcoin halving event is projected to occur sometime between around April 2028. This pre-programmed code will again cut the block reward for miners in half, reducing it from the current 3.125 BTC to 1.5625 BTC per block.
While April 2028 is a well-educated estimate, the exact date can't be pinpointed due to the technical intricacies of the bitcoin protocol.
Factors like variations in block mining times influence the precise timing. These variations are a normal part of how the Bitcoin protocol operates and are an important factor in its decentralized design.

How Bitcoin halving affects miners and the market
The bitcoin halving event has an effect throughout the cryptocurrency ecosystem, impacting both the miners who secure the network and the broader market where bitcoin is traded.
The halving event incentivizes miners to become more efficient in order to remain competitive. The more powerful a miners hardware is and the less they spend on electricity costs, the more profitable their operation will be.Because of this, miners often focus on lowering operational costs, increasing their computational power and finding cheaper sources of electricity.
Halvings also repeatedly prove that the amount of bitcoin that exists is finite and that the rate at which bitcoin enters the market continues to slow over time. History has shown that this reduction in supply can influence market dynamics and potentially lead to increased demand and price appreciation.
Miners
The bitcoin halving impacts bitcoin mining and its profitability. With block rewards cut in half, miners face a reduced income. This incentivizes miners to adopt more powerful hardware and cheaper electricity to stay competitive.
While the mining difficulty, or computational effort required to mine a block, adjusts periodically to maintain bitcoin’s operation, the pressure to upgrade equipment to more efficient and powerful machines remains constant. New, more efficient hardware emerges regularly, and miners risk losing out on profits if they don't use the latest, most powerful machines.
Bitcoin's price, energy costs and technological advancements all significantly impact miner profitability.
Market
The halving reduces the daily issuance of new bitcoin, thereby reducing the speed at which new bitcoin enters circulation. Historically, bitcoin's price tends to increase following halving events.
However, the market is nuanced, and we can't contribute price movements solely to the halving for a few reasons:
- Market complexity: Various factors like institutional adoption and evolving regulations can significantly influence market movements.
- Speculative volatility: The anticipation surrounding the halving can lead to increased volatility, with prices fluctuating significantly before and after the event.
- Isolating the impact: Distinguishing the halving's specific impact from these external factors remains difficult.
Additionally, factors like evolving regulations can significantly influence market movements.
What to expect from future halvings
At the current block production rate, the next bitcoin halving will likely occur in early 2028.
The actual date can fluctuate slightly depending on variations in mining difficulty. The last halving is expected to take place in 2140, at which point all 21 million bitcoin will have been mined.
While some analysts predict future halvings could trigger similar price trends as observed historically, past performance is not necessarily indicative of future results. Be sure to do your own research so you can make informed decisions at every stage of your crypto journey.
Here's how investors can prepare for the next halving event:
- Conduct thorough research: Don't base investment decisions solely on speculation surrounding halving events.
- Consider historical data: Analyze historical price movements and market trends associated with past halvings.
- Practice sound risk management: Bitcoin is a volatile asset, and investing in it carries inherent risks. Develop a sound risk management strategy before making any investment decisions.
Taking a measured approach and conducting thorough research can better prepare you to navigate the potential opportunities and challenges of future bitcoin halving events.
