Bitcoin Halvings

Bitcoin halving is one of the most crucial events to occur on the blockchain. Halving promotes inflation in Bitcoin's price by lessening the number of bitcoins in circulation and thereby elevating the demand for this cryptocurrency. Bitcoin halvings affect all stakeholders in the Bitcoin ecosystem significantly.

What Is Bitcoin Halving

One block is the equivalent of one megabyte of Bitcoin transaction records on the Bitcoin blockchain. Bitcoin miners compete against one another to be the first to add the next block. This is achieved when a miner solves a complex mathematical problem with the help of advanced hardware. The hardware ultimately produces a 64-character yield referred to as a hash, which finalizes the process and locks the newly generated block so it cannot be compromised. For this work, users receive mining rewards in the form of bitcoin.

At the time of its inception, Bitcoin miners received 50 BTC per block. This was an attractive feature even before the immense success of Bitcoin was evident. The rate of bitcoin creation decreases by 50% every four years until the entirety of 21 million bitcoins has been mined.

The first halving occurred in 2021 when the reward for mining a block decreased from 50 BTC to 25 BTC per block mined. Furthermore, Bitcoin halving dates history displays the occurrence of halvings in 2012, 2016, and again in 2020.

The last halving event reduced the incentives to 6.25 BTC per block mined. The next Bitcoin halving event will result in a decreased reward of 3.125 BTC. This cycle is expected to continue until approximately 2140, before all existing bitcoins have entered circulation.

Why Does Bitcoin Halving Happen?

The Bitcoin mining algorithm dictates that a new block is found every 10 minutes. As new miners join the network, adding to the hashing power, the time it takes to generate new blocks will decrease.

In order to maintain a ten-minute intent, the mining difficulty is reevaluated and reset every fortnight. As a result, the time it takes to find a new block has averaged below ten minutes despite the dramatic growth of the Bitcoin network over the last decade.

Bitcoin's supply is established as 21 million units, and the generation of new bitcoins will cease when this number of bitcoins is reached. Bitcoin halving events ensure that the number of bitcoins that can be mined with each block decreases as time passes, contributing to the rarity and value of BTC.

One would expect mining incentives to drop after each halving occurred, but the enormous increase in Bitcoin's value motivates miners to mine even more despite their payouts being halved.

Bitcoin miners are driven by the continued growth of the price of Bitcoin. This will not be the case if the value of this digital currency does not increase and block rewards are to decrease. Bitcoin mining is an expensive and time-consuming process, which would certainly not be worth it were it not for the substantial rewards.

The Implications of Bitcoin Halvings

The broader implications of Bitcoin halving involve the reduction in the amount of money miners can earn by adding new transactions to the blockchain due to a decreased reward for mining.

The number of new bitcoins that enter circulation depends on mining rewards. Halving the payouts decreases the influx of bitcoins. At this point, the law of economics comes into play. As the supply decreases, the demand and with it, the value increases.

A halving event results in a reduction in Bitcoin's inflation rate. This inflation is the loss of purchasing power which, in this case, is the digital currency. Bitcoin's fundamental infrastructure was created to be a deflationary asset, and halving is crucial in maintaining this status.

Bitcoin's inflation rate levelled at 50% in 2011 but dropped to 12% after halving occurred in 2012. This rate declined again in 2016 and currently stands at 1.77%. As a result of these halvings, the value of Bitcoin continues to increase. As Bitcoin's supply decreases, its demand rises, causing a bull run for this cryptocurrency.

The expenses of Bitcoin mining are undoubtedly high because it includes not only the cost of the hardware, but also the electricity used to power the mathematical computations. Because of these high prices, the mining reward has to be significantly high to make it worth miners' money and time.

If a technology with the ability to generate a larger amount of hashes per second enters the market, it will definitely be in high demand.

Moreover, the extensive visibility that Bitcoin is now receiving is expected to increase its value. The number of transactions will rise drastically as more small businesses, stores, and large institutions engage in mining and participates in Bitcoin's blockchain operations.

What Will Happen If A Large Number Of Miners Withdraw?

To understand the consequences of a significant number of miners dropping out, we first need to consider the hash rate. The hash rate is the number of SHA256 computing operations carried out per second. The hash rate rises as more miners join the network, leading to a more secure and fast network.

If a great number of miners suddenly retract at the same time, a bottleneck effect will occur, where network users move to faster chains and make it remarkably easier for fraudulent activity to occur.

However, history has proven this theoretical implication to be untrue. After the first halving, the network's hash rate dropped temporarily. Thereafter, both the mining profitability and the hash rate increased. Conclusively, after a considerable drop in hash rate, the network and its miners alike ultimately benefit from halving.

After Bitcoin's second halving, the same trend was evident. It merely took a bit longer for the hash rate to stabilize, although the mining profitability did not fully recover for almost a year after the halving event. If this trend persists, profitability may be the area that will suffer a long-term diminishing effect.

What Happens When There Are No More Bitcoins Left in a Block?

By the year 2140, all 21 million bitcoins will have entered circulation. The halving schedule will end because there will be no more bitcoins left to mine. Miners will still be able to confirm and validate new transactions occurring on the blockchain. Miners will also be incentivized to do so as the transaction fees they earn are expected to increase. This increase is because a larger transaction volume that includes transaction fees will be included, causing a greater nominal market value.

How Does Bitcoin Halving Effect The Price Of Bitcoin?

Since Bitcoin's launch in 2009, when it traded at meager prices, the price of Bitcoin has risen steadily to $63 000 in 2021.

As sellers need to adjust their selling prices to justify their costs, Bitcoin halving positively impacts the price because halving the block reward doubles miners' costs.

Evidence suggests that the price of Bitcoin increases in anticipation of halvings, usually a few months prior to the halving event.

How Halving Affects Bitcoin's Network

Being a major event, Bitcoin halving significantly influences all the involved parties on the network. Following is a brief layout of how halvings affect stakeholders and topics of conversation in the Bitcoin network.


Halvings are extremely beneficial for investors as the decline in supply leads to surging demand and thereby higher prices.

This digital asset's trading activity escalates when a halving is anticipated. The increase in pace and price depends on the condition and logistics of the halving event.


Although a diminished supply raises the demand and price of bitcoins, lower rewards may present unique challenges for individual miners trying to keep their heads above water in competing with large mining organizations. Research suggests that the ratio between Bitcoin's mining capacity is oppositely correlated, meaning that as the cryptocurrency's price increases, the number of miners decreases and vice versa. A halving event brings about a higher probability of a 51% attack on the network, contributing to security threats.

Why does Bitcoin Halving Matter?

Halving presents opportunities to profit from the increase in value resulting from the decrease in supply. Bitcoin halving is frequently associated with commotion.

The first Bitcoin halving occurred in 2021 when the price of Bitcoin was $12. After this event, the value of BTC had increased to almost $1000. In 2016 the second halving occurred, resulting in the price of Bitcoin dropping to $650 before rising to $2550 by July in 2017.

By the end of 2017, Bitcoin prices achieved an astonishing high of $19 700. After the most recent halving, the cost of BTC was $8 787 before exploding once again.

Other elements also played a role in the drastic booms following Bitcoin's halving:
  • The growing fascination with the digital asset's anonymity.
  • The increase in usability of the digital currency.
  • The rise in press coverage of Bitcoin and other cryptocurrencies in general.

If you consider the history of Bitcoin's value applicable, there is no denying that halvings have been bullish motivators for Bitcoin's value.

However, the third halving is sure to impact the Bitcoin ecosystem in several ways.

Primarily, the number of Bitcoin miners is expected to decline due to mining becoming less attractive for less profitable miners.

Bitcoins halvings display the deflationary nature of this cryptocurrency. Since its birth, this has been the central point of the bull case for Bitcoin, meaning that central banks or the government cannot eradicate Bitcoin, and the entire supply is admitted.

Key Takeaways

Bitcoin Halving counters the effects of inflation and reduces the rate of new bitcoin generation by 50%. The mining rewards system is predicted to continue until all 21 million bitcoins have entered circulation, which is expected to happen by the year 2140.

After these rewards cease to be implemented, miners will exclusively earn transactions fees.

The reward for a block mined was 50 BTC back in 2009. The first halving resulted in a reward of $25, which became $12.5 before halving again in 2020.

The implications of Bitcoin halving include an increase in prices in the days and months leading up to a halving event. In addition, miners can expect a boost in their ranks as discrete miners, while less profitable miners may be excluded from the Bitcoin ecosystem or are absorbed by more prominent players.
