Bitcoin halving 2020: what you need to know

Bitcoin (BTC) halving is estimated to occur sometime in May 2020. When bitcoin has halved in the past, price fluctuations usually follow. We look at what bitcoin halving is and how it can impact your cryptocurrency portfolio. We'll analyse BTC halving from a technical and fundamental perspective to give insight into what could happen and how to trade it.

What is bitcoin halving?

Bitcoin halving is an event where the block reward for mining new bitcoin is halved, meaning that bitcoin miners will receive 50% less bitcoin for every transaction they verify. BTC halving occurs every 210,000 blocks, which equates to a halving occurring approximately every 4 years.

Although this can sound confusing with concepts such as ‘block reward’ and ‘verifying transactions’, bitcoin halving is a relatively simple process.

When a block of bitcoin is successfully mined, the bitcoin miner receives a block reward – essentially a BTC payment. However, the bitcoin halving process follows cryptocurrency economic theory. As bitcoin has a finite amount and its supply is reduced over time, the price of bitcoin can be kept ‘stable’ and deflationary by reducing the overall supply – this is why bitcoin halving exists.

Bitcoin halving 2020

The next bitcoin-halving event is expected to occur the week commencing the 18May 2020. However, please note that this date can vary, as the time taken to generate new blocks can also vary. However, it's certain that bitcoin halving will occur when block 630,000 is mined.

Currently, 12.5 bitcoins are rewarded to miners per block. However, this will decrease to 6.25 BTC per block after the bitcoin halving event in 2020.

Historical bitcoin-halving dates

Bitcoin halving has occurred twice before. First in 2012, where the reward per block dropped from 50 to 25 bitcoins. Following this, another halving occurred in 2016, where the reward per block dropped from 25 to 12.5 bitcoins. See below for a more detailed explanation into the history of bitcoin halving and predictions for the future.

Halving 6Expected 20321,260,0000.78125164,062.599.21875

As you can see from the above table, the amount of bitcoin mined and the block reward drops by half at every halving event. By 2032, over 99% of bitcoin will have been mined and it is estimated to take up until 2140 until 100% of the total bitcoin is mined.

Bitcoin halving: fundamental analysis

Bitcoin halving is a trading indicator for fundamental analysts, as it’s a direct force that will impact the supply and demand of bitcoin. The halving process reduces the future supply of bitcoin by 50% for the next 210,000 blocks, when this process will repeat again. If demand stays constant, and this factor is not already priced into the market value of bitcoin, the value of bitcoin would rise. However, it's increasingly difficult to determine the intrinsic value of bitcoin due to its complexity.

Bitcoin halving: your questions answered

When is the next bitcoin halving?

The next bitcoin halving is estimated to occur sometime following after 18 May 2020. However, this is just an estimation, as there is no set date. Bitcoin halving occurs when the 630,000th block is mined. This bitcoin halving will see the mining reward drop from 12.5 bitcoins per block to 6.25 bitcoins.

What happened last time bitcoin halving happened?

The last time bitcoin halving happened on 9 July 2016, block 420,000 was mined. This saw the mining reward drop from 25 bitcoins per block to 6.25 bitcoins per block. Bitcoin also experienced some price fluctuations before, during and following its 2016 halving. The price of bitcoin rose from around $450 in April 2016 to around $650 at the time of the halving. Following this, volatility ensued in the market but bitcoin’s price continued to steam ahead over the next year, hitting highs of nearly $20,000 before dropping down to around $10,000 at the start of 2018.

How will bitcoin’s price change following the next bitcoin halving? 

It’s impossible to predict future bitcoin price changes during the next halving period, just as it is impossible to attribute bitcoin halving to previous price changes. However, we can analyse the previous highs from bitcoin halving 1 and 2, where major price increases were evident:

Bitcoin launch to first halving: Price increases from $31.50 to $1,178 (3,700% increase)

First halving to second halving: Price increases from $1,178 to $19,800 (1,600% increase)

Second halving to third halving: TBC

While the above data is far from producing any meaningful projections or insights into the bitcoin’s price action, it simply showcases what has happened in the past. 


Bitcoin halving is a fundamental event that changes how much bitcoin is supplied from mining. Although it should not be used in solitary as a trading indicator, it can be used alongside other fundamental or technical analysis factors to help determine bitcoin’s future price action.
