Bitcoin halving 2020

What is the Bitcoin Halving (Halvening)?

New bitcoins are issued by the Bitcoin network every 10 minutes. For the first four years of Bitcoin's existence, the amount of new bitcoins issued every 10 minutes was 50. Every four years, this number is cut in half. The day the amount halves is called a "halving" or "halvening".

In 2012, the amount of new bitcoins issued every 10 minutes dropped from 50 bitcoins to 25. In 2016, it dropped from 25 to 12.5. Now, in the 2020 halving, it will drop from 12.5 to 6.25.

What is the Significance of the Bitcoin Block Halving?

The halving decreases the amount of new bitcoins generated per block. This means the supply of new bitcoins is lower.

In normal markets, lower supply with steady demand usually leads to higher prices. Since the halving reduces the supply of new bitcoins, and demand usually remains steady, the halving has usually preceded some of Bitcoin's largest runs.

Bitcoin Halving Schedule

The Bitcoin halving is scheduled in block height, not date.

The halving happens every 210,000 blocks. The 2020 halving will happen on block 630,000. The 2024 halving will happen at block 840,000.

What Happens to Miners During Halvings?

Many always speculate that miners will shut down after the halving. The reality is most miners are very smart and price in the halving, so they don't end up shutting down any miners.

When is the 2024 Bitcoin Halving?

The 2024 halving will likely occur between March 2024 and June 2024.

The Bitcoin clock has been around since 2011. In 2018, the owner let the domain expire. We revamped the site and restored it to its original vision.

Is the Halving Necessary?

The halving is necessary. This is how Bitcoin controls its supply. Once the block subsidy expires, transaction fees will pay miners for securing the network.

Why Our Estimates Are the Most Accurate

Most of the other halving date estimators use 10 minute blocks to calculate the estimated halving date.

Blocks, however, have been mined at less than 10 minute intervals for almost all of Bitcoin's history.

Our calculator uses data from BTC.com to get the average block time for the past two months. It then uses this block time (currently 10.3125 minutes between blocks as of March 25, 2020) to estimate the halving date.

While most of the other sites estimate the halving for late-May, the more likely outcome is an early     What is the Current Bitcoin Block Reward?

Currently, there are 12.5 new bitcoins issued per block.
