Bitcoin Halving – When Will Bitcoin Halving Happen?

Bitcoin Halving - When Will Bitcoin Halving Happen?

Bitcoin halving occurs approximately every four years and involves actively reducing the block reward given to miners, resulting in a halving of newly minted bitcoins. Bitcoin is the most known cryptocurrency, and its usage is expanding as more people are recognizing its benefits and potential. Computers running Bitcoin’s software, called nodes, make up the Bitcoin network. It hosts the public ledger which stores all transactions, known as Blockchain. The Bitcoin network approves or rejects transactions and performs a series of checks to ensure the validity of each transaction.

This process includes the check about the length of the transaction. After approving all the transactions in a block (set of transactions), the network individually approves each transaction. After approval, the network adds the transaction to the existing blockchain, thereby increasing the stability and security of the blockchain through the addition of more nodes. Everyone who can download the entire blockchain and its transaction history can participate in Bitcoin’s network. The participants who contribute their power and energy to the Bitcoin network are actively called miners.

Explanation of Bitcoin Mining

Proof of work is a process where Bitcoin miners compete to solve challenging mathematical puzzles. The duties of a miner are to validate transactions, solve mathematical puzzles, and then obtain rewards. Each time someone sends Bitcoins to another person, they actively send a transaction to the Bitcoin network. Nodes, or computers that run the Bitcoin software, validate transactions. Miners group transactions into blocks, gathering a specific number of transactions into each block. Each block comprises a header (block version number), a list of transactions, and a nonce—a random 32-bit number utilized by miners as the basis for their hash calculations. Miners actively combine the block header and nonce to solve mathematical puzzles. The network receives the answer when the miner has finished solving the problem. If the solution is acute, nodes in the network can confirm it. When the network verifies the solution, it actively rewards the miner.

Bitcoin Halving

Bitcoin halving is a process that happens approximately every four years in the Bitcoin network. Every four years, the Bitcoin network reduces the amount of newly generated Bitcoin through mining. When the Bitcoin network mines 210,000 blocks, it actively cuts the reward given to Bitcoin miners for processing transactions in half. It refers to the process of dividing the reward for Bitcoin miners in half for blocks they mine. Bitcoin halving ensures control of the supply of new Bitcoins that enter the market. It also ensures that there are no more than 21 million Bitcoins in existence overall.

The Bitcoin protocol actively prevents the mining of new Bitcoins once the limit of 21 million Bitcoins is reached, resulting in this limitation. The halving process slows down the creation of new Bitcoins, making it challenging and costly for miners to earn rewards. Active consideration is given to maintaining Bitcoin’s scarcity and its value as a digital cryptocurrency, recognizing it as an important aspect. However, halving remains just one of many factors that affect the price of Bitcoin, it does not ensure a rise in its value.

Bitcoin Halving Over Years – When Will It Happen Again?

The Bitcoin mining process started in January 2009, and the reward for mining a block was 50 BTC (Bitcoin). Satoshi Nakamoto, the creator of Bitcoin, set this reward to actively encourage miners to secure and support the Bitcoin network. In 2012, the first Bitcoin halving occurred, reducing the reward per block from 50 Bitcoin to 25 Bitcoin. This process continued to happen every fourth year until nowadays. The second halving occurred in 2016, cutting the reward in half from 25 Bitcoin to 12.5 Bitcoin. The most recent Bitcoin halving took place in May 2020, reducing the reward to 6.25 Bitcoin. Anticipations are that the next Bitcoin halving will actively happen around the year 2024, approximately four years from now. The reward would be cut in half from 6.25 Bitcoin to 3.125 Bitcoin.

Why is it Hard to Predict the Exact Time of Bitcoin Halving?

The exact time of the next Bitcoin halving is difficult to predict because many factors influence it. It could be the hash rate of the network and the block creation time. The average time of block creation is 10 minutes, but some blocks take more and some take less time. As a result, the time it takes to accomplish the next halving target can decrease or increase. To mine the 210,000 blocks, it would take around 1,409 days (1461 = four years). The calculations consider an average block speed of 9.66 minutes. This explains why it is hard to predict the exact date of Bitcoin halving.

When would Bitcoin Halving Stop?

Bitcoin halving will actively continue to occur until the maximum quantity of 21 million Bitcoin is achieved, with an expected completion date in the year 2140. Until that year, Bitcoin halving will actively happen every four years. Once miners have actively mined 21 million Bitcoins, mining will cease to produce new Bitcoin. Miners will rely on transaction fees to keep processing transactions and maintain the security of the network. 

Why is Bitcoin Halving Important?

Bitcoin halving is an important event in the Bitcoin network and cryptocurrency industry. This process results in a reduction in the overall quantity of Bitcoin. The Bitcoin supply reduces, increasing its price, while the demand remains constant or increases. As a result, Bitcoin halving is an important event for traders and investors in the cryptocurrency market. It has a significant influence on the price of Bitcoin.       



  • Bitcoin is the most known cryptocurrency, and its usage is growing every day.
  • Bitcoin mining is a process where miners solve mathematical puzzles and when the solution gets confirmed they earn rewards. 
  • Bitcoin halving started in January 2009, and the reward for mining was 50 Bitcoins.
  • This process happens every four years, and it cuts in half the reward.
  • The last halving process was in 2020, and the reward was reduced to 6.25 Bitcoins. 
  • It is hard to predict the exact time when the next halving process would happen because the time of block creation is not the same for all blocks.
  • This process of producing 21 million Bitcoins is expected to actively occur until the year 2040.
  • The Bitcoin halving is important because it has an important impact on the price of Bitcoin.
