What is the Bitcoin halving?
Bitcoin is limited to its supply — only 21 million Bitcoin will ever be created to exist.
This sets Bitcoin apart from national currencies which can create an unlimited supply; making it a deflationary asset.
In order to 'create' Bitcoin tokens, Bitcoin miners use computing devices to solve an algorithmic puzzle that rewards them with Bitcoin tokens.
The first sum of Bitcoin rewarded, known as the block reward, was 50 Bitcoin (BTC) and 비트코인 거래소 could be done using a laptop. At that time, Bitcoin was not worth a lot.
Now, mining Bit-coin is a much more involved process that requires specialized equipment and a lot of energy and electricity.
The block reward is also no longer 50 BTC — at the moment, it is only 12.5 BTC.
So why the change?
Every time 210,000 blocks of Bitcoin are mined, the block reward is halved. This is known as «the Bitcoin Halving». This halving has happened twice.
When is the next Bitcoin halving?
The first time was in November of 2012 when the block reward was sliced from 50 BTC to 25 BTC per block.
The second Bit-coin halving was in July of 2016 when the reward went from 25 BTC to the current reward of 12.5 BTC per block.
The next halving is predicted to happen around May 2020 and will see the reward fall to 6.25 BTC per block. This prediction is based on how many blocks need to be mined until the next halving and the amount of time it takes for each block to be mined.
Why is there a Bitcoin halving?
If the asset has a finite number of units, why does creating it then need to halve the reward if they will all be in circulation one day anyway?
Basically, 비트코인 거래소 the Bit-coin halving slows the production of Bit-coin tokens which helps keep the value. If too many tokens existed all at once, each Bit-coin would have little value because there would be too many available without enough time for them to be adopted.
Ethereum co-founder Vitalik Buterin put it this way:
«The main reason why this is done is to keep inflation under control. One of the major faults of traditional, «fiat», currencies controlled by central banks is that the banks can print as much of the currency as they want, and if they print too much, the laws of supply and demand ensure that the value of the currency starts dropping quickly. Bit-coin, on the other hand, is intended to simulate a commodity, like gold. There is only a limited amount of gold in the world, and with every gram of gold that is mined, the gold that still remains becomes harder and harder to extract. As a result of this limited supply, gold has maintained its value as an international medium of exchange and store of value for over six thousand years, and the hope is that Bitcoin will do the same.»
Will the halving affect Bitcoin's price?
In the past, the Bit-coin halving has had a significant impact on the price of Bitcoin. One of the prominent reasons for this points to the theory of supply and demand.
As fewer Bit-coin tokens are generated, the value of those tokens increases. The scarcity of Bitcoin then translates to value and the price rises.
After the two halvings, the Bitcoin price surged about a year later. The first halving took place in 2012, and 2013 saw a bull run spike when Bitcoin reached $1000 — which was an unprecedented high.
The second halving occurred in 2016, and Bit-coin shot to its famed all-time high of $20,000.
Although two spikes might not be enough evidence to show that Bit-coin surges after a Bit-coin halving, the timing of the major bull runs is worth noting.
If the next halving is going to follow the trend, then we will see the price of the cryptocurrency skyrocket.
