Bitcoin Halving - everything you need to know about the process

Bitcoin is the oldest and by far the most successful cryptocurrency on the market. More and more people and global companies are buying, selling and making payments with the digital currency every day - and yet Bitcoin is so much more than just a means of payment or investment asset. Because behind the digital coins lies a complex network full of exciting processes. We would like to introduce one of them to you in more detail today: Bitcoin Halving.

What is Bitcoin Halving?

Unter Bitcoin Halving versteht man die Halbierung der Mining Belohnung im Bitcoin Netzwerk. Es handelt sich dabei um eines der wichtigsten Ereignisse in der Bitcoin Blockchain. Denn das Halving sorgt für eine Inflation, und das wiederum erhöht die Nachfrage nach Bitcoin. Das Bitcoin Halving hat Auswirkungen auf alle Beteiligten innerhalb des Bitcoin-Ökosystems.

Short and compact:

  • Bitcoin halving is when the reward for mining Bitcoins is reduced by half.
  • Halving halves the inflation rate of Bitcoin and the rate at which new Bitcoins come into circulation.
  • Previous Bitcoin halvings always resulted in the Bitcoin having a higher value after the halving than before.
  • The last Bitcoin halving to date took place on May 11, 2020. The block reward for miners was reduced from 12.5 to 6.25 BTC.

A small introduction to the Bitcoin network

Now, in order to explain to you in more detail what actually happens in Bitcoin halving, we first need to talk a little bit about how the Bitcoin network works.

What is the Bitcoin network made up of?

The Bitcoin network is based on a technology called Blockchain. To put it simply, the blockchain consists of very, very many computers on which the Bitcoin software runs. These computers are also called Nodes.

Nodes contain a copy of all transactions ever made on the Bitcoin network. Each node is responsible for approving or rejecting a transaction on the Bitcoin network.

This means: Nodes perform lots of security checks to ensure that a transaction is valid.

After a transaction has been approved by the nodes, it is attached to the existing blockchain - becoming part of the Bitcoin network itself.

The more computers or nodes work with the Bitcoin blockchain, the more stable and secure it is. There are currently more than 10,000 nodes running the Bitcoin software.

Bitcoin Mining

Bitcoin mining is the process by which people use their computers to participate in the Bitcoin blockchain network. The people behind Bitcoin Nodes are so-called Miners. They use their computers to process and validate the transaction on the Bitcoin blockchain.

Bitcoin uses a system called Proof of Work (PoW). This means that miners have to prove that they made some effort when processing transactions in order to be rewarded. This effort includes the time and energy required to run the computer hardware and solve complex equations.

Basically, Bitcoin miners solve mathematical problems and thereby confirm the legitimacy of a transaction. They then add these transactions to a block and create chains of these transaction blocks, which in turn form the blockchain. When a block is filled with transactions, the miners who processed and confirmed the transactions within the block are rewarded with bitcoins.

Bitcoin Halving - detailed explanation

With this prior knowledge, we can now plunge into the main topic of this article: Bitcoin Halving.

After every 210,000 blocks processed - roughly every four years - the reward Bitcoin miners receive for processing transactions is halved. This event is called a halving. Because the mining reward also halves the rate at which new bitcoins are brought into circulation. In this way, Bitcoin forces artificial price inflation.

Bitcoin halving

Incidentally, this reward system for miners will only continue until around the year 2140. Because then the upper limit of 21 million Bitcoin will probably be reached. From this point on, no new bitcoins will be produced.

Instead, from then on, miners will be rewarded with fees for processing transactions, which will be paid by network users. Of course, this should ensure that miners continue to have an incentive to validate transactions and thus keep the network running.

The Bitcoin network is therefore approaching its finiteness. The Bitcoin Halving is important for this in that it means a decrease in the production of new Bitcoins: The maximum total amount of Bitcoins is 21 million. At the end of May 2022, around 19 million bitcoins were already in circulation. This also means that there are only about 2 million bitcoins left to be released via mining rewards.

In 2009, the reward for each mined block was 50 bitcoins. After the first halving, it was 25, then 12.5, and finally 6.25 bitcoins per block from May 11, 2020.

Let's use an example here: imagine that the amount of gold that is mined from the earth is halved every four years. The value of gold increases depending on how much of it is currently on the market (supply and demand). So, in theory, halving gold production every four years would drive up the price.

Effects of Bitcoin Halving

In the past, Bitcoin Halvings were always associated with massive price increases.

Before the first halving on November 28, 2012, BTC stood at €12. A year after the halving, on November 28, 2013, the coin was valued at a whopping €1,217.

The second Bitcoin Halving took place on July 9, 2016. At the time of this halving, the price of BTC was €647. On December 17, 2017, the price of a bitcoin had risen to €19,800.

The last Bitcoin Halving to date took place on May 11, 2020. On that day, the price of one bitcoin was €8,787. On April 14, 2021 - not quite a year later - the price of a bitcoin had risen to €64,507! A 634% increase from pre-halving levels!


The theory behind the halving process

The theory behind Bitcoin Halving and the chain reaction it triggers works something like this:

Reward for miners is halved → inflation halved → lower supply → higher demand → higher price

This is how the miners also benefit from Bitcoin Halving:

Now you could of course ask: But what do the miners actually get from Bitcoin Halving? The reward for completing transactions is getting smaller after all!

That is correct so far. But Bitcoin has come up with an interesting solution to keep its miners (on whom the whole system is based, after all) in line:

Namely, with Bitcoin, there is a process that can be used to change the effort required to receive mining rewards. When the rewards for miners were halved, the difficulty of bitcoin mining was also reduced in the same breath.

This means that while miners still receive a smaller reward than before, the energy and time required for mining also decreases. As a result, mining is still profitable in most cases even after a Bitcoin halving. 

What external factors influence Bitcoin Halving?

From 2017 to 2018, the value of a bitcoin rose to around €20,000 - only to fall back to around €3,000 a little later. A massive drop.

Es ist allerdings immer auch eine Frage der Perspektive: Wenn man bedenkt, dass der Preis eines Bitcoins vor dem Halving 2016 bei etwa 650 € lag, kann man dennoch von einer beachtlichen Preissteigerung sprechen.  

Although this system has worked so far, bitcoin halving is usually always surrounded by immense speculation, hype and volatility.

Not only did the third halving take place during a global pandemic, but it was also accompanied by high speculation, increased interest in digital assets, and hype from quite a few celebrities.

How does Bitcoin Halving affect the Bitcoin network?

The Bitcoin Halving every four years is a huge event. It is therefore understandable that the halving has a major impact on the various parties in the Bitcoin network. We briefly summarize the consequences of Bitcoin Halving for the main players in the Bitcoin network.


Investors: The halving typically results in a up in bitcoin prices due to reduced supply and increased demand. Good news for all investors!


Miner: The effects on Bitcoin miners are a bit more complex. On the one hand, the lower Bitcoin supply increases demand and prices. Fewer rewards can also make it difficult for individual miners or small mining companies to survive in the Bitcoin ecosystem. According to research, Bitcoin’s mining capacity is counter-cyclical to its price. So when the price of the cryptocurrency increases, the number of miners in its ecosystem decreases and vice versa.

When will the next Bitcoin Halving happen?

In all likelihood, the next Bitcoin Halving will occur in early 2024.

What happens when there are no more bitcoins at some point?

Around the year 2140, the cryptocurrency will have reached its upper limit of 21 million bitcoins. From then on, there will definitely be no more Bitcoin halvings, since no new coins can be mined.

However, there is still an incentive for miners to validate and confirm new transactions on the blockchain. The plan is to pay the miners in transaction fees.

Fazit – was Du Dir merken solltest:

  • The bitcoin halving artificially inflates the price of the cryptocurrency network, halving the rate at which new bitcoins are circulated.
  • The reward system is expected to continue into 2140. After that, miners are rewarded with fees for processing transactions.
  • In 2009, the reward for each mined block was 50 bitcoins. After the first bitcoin halving it was 25, then 12.5 and from May 11, 2020 6.25 bitcoins per block.
  • The Bitcoin Halving has a significant impact on the network. Investors can expect the price to surge in the days before and after the halving.
  • Bitcoin halving can be quite uncomfortable for miners. Due to the lower mining rewards, individual miners or small companies may drop out of the mining ecosystem.
