Following this event, the Bitcoin block reward decreased from 12.5 to 6.25 BTC per block, effectively slashing the earnings from Bitcoin mining by 50%.This follows the first halving in November 2012 - from 50 to 25 BTC per block, and the second halving in July 2016 - from 25 to 12.5 BTC per block. Bitcoin block reward halves roughly every 4 years, with the 4th halving set to take place in <a href="https://coinmarketcap.com/halving/bitcoin/">2024</a>.Here’s how key metrics for Bitcoin have changed since the halving:<table>

A difficulty adjustment takes place every 2,016 blocks - roughly every 14 days - to ensure the interval between mined blocks stays fixed at around 10 minutes. If a large number of miners switch off from the network - as would happen following a block halving event - the interval between blocks becomes longer than 10 minutes and the network adjusts (decreases difficulty) to encourage participation.<figure class="kg-card kg-image-card"><img src="http://static.delta.exchange/wp-content/uploads/2020/05/ch3.png" class="kg-image" alt loading="lazy" width="1166" height="860"></figure>Hash Rate &amp; PriceThe hash rate of the Bitcoin network tends to follow the price of Bitcoin, closely reflecting miners’ significant sensitivity to Bitcoin price. This is even more true in the aftermath of the block reward halving as the reduction in the number of Bitcoins mined everyday increases the dependence on Bitcoin price rise to maintain margins. [caption id="attachment_25033" align="aligncenter" width="512"]<figure class="kg-card kg-image-card"><img src="http://static.delta.exchange/wp-content/uploads/2020/05/ch2.jpg" class="kg-image" alt loading="lazy" width="512" height="285"></figure>BTC Price + Hash Rate since May ‘17[/caption] A block reward halving - as seen on May 11th - can theoretically be thought of as a 50% fall in the price of Bitcoin for miners, with revenue dropping overnight. As a consequence of this, the hash rate has fallen accordingly (-21.67% since the halving) and is likely to fall further in the near future if not for significant price growth. Falling hash rate is reflective of inefficient miners shutting down due to their inability to mine Bitcoins profitably in the post-halving world. Any volatility in price only exacerbates this situation, with larger players (with more efficient set-ups) surviving to a larger share of the pie. In the medium to long-term however, competition - and subsequently the hash rate - will increase again as difficulty adjusts and new players with more efficient hardware enter the market. The 2nd Halving - What Can We Learn?4 years ago, on July 9th 2016, Bitcoin underwent its second network halving where the block reward fell from 25 BTC to 12.5 BTC per block. Bitcoin was up more than 45% in the 3 months leading up to its 2nd halving, before falling 30% - to $530 - in the two weeks after. Bitcoin hit a new high 8 months later before rallying to $20,000 just 17 months later. [caption id="attachment_25039" align="aligncenter" width="1600"]<figure class="kg-card kg-image-card"><img src="http://static.delta.exchange/wp-content/uploads/2020/05/ch4.png" class="kg-image" alt loading="lazy" width="1600" height="808"></figure>BTC Hash Rate in 2016 - the year of 2nd halving[/caption] Both hash rate and price were generally on a positive run in 2016. The hash rate started the year at 770.5k TH/s, hitting 1.55m on the day of the halving before falling to 1.40m two weeks later. However, in  the next two years the hash rate rose exceptionally to 54m TH/s - an increase of over 3757.14%. The hash rate then too was following Bitcoin price action. BTC started 2016 at $435, hitting $632 the day of halving (up 46.7%). In the two weeks after, BTC fell to a low of $549 (-13.97%), before going on a run that would end at $19,990 just 15 months later. This year, the dynamics are different. Bitcoin is currently on a strong run but largely due to an equally strong crash on March 12th. Similarly, the hash rate in 2020 has been volatile, with no clear pattern distinguishable. Bitcoin hash rate has been incredibly volatile throughout the first quarter of 2020, swinging between 90m-125m TH/s. A volatile Bitcoin price and the impending halving are the key factors behind this.<figure class="kg-card kg-image-card"><img src="http://static.delta.exchange/wp-content/uploads/2020/05/ch5.png" class="kg-image" alt loading="lazy" width="1600" height="802"></figure>Adjusting To A HalvingA Bitcoin halving is an event that is well known in advance, with all future halvings laid out for all to see. Whilst miners prepare for it and make the necessary efficiency adjustments, a near 50% cut in revenues inevitably comes as a big shock regardless of preparations and adjustments are required. To understand the impact of halving, we first need to know the levers of a Bitcoin miner’s revenue. 24h Miner $Revenue = (Miner Hash Rate/ Network Hash Rate) * (BTC Mined/ Day) * BTC_PriceBTC mined per day is determined by the network protocol. After each halving BTC mined per day is cut in half. A miner’s share in the network hash rate can change due to: (a) increases/decreases in the network hash rate as others parties enter/exit and (b) investment by miners in more and/or better hardware that leads improvements in the miner’s hash rate. Now that we understand the revenue drivers of a Bitcoin miner, let’s analyse how miners adjust to the post-halving world. Fiat denominated revenues are important for a miner because costs are primarily denominated in fiat.[a] Bitcoin price: A jump in the BTC price can offset the loss in USD revenue due to block reward halving. Ceteris paribus - i.e. hash rate &amp; trxn fees remain unchanged - the price of Bitcoin would have to go up by 98% - to $19998 - for miners fiat-denominated revenue to go back to pre-halving levels.<table>

</table>[b] Hash rate: The Bitcoin hash rate is a measure of the network’s competitive intensity. Since halving network hash rate is down ~21.67%% as a consequence of inefficient players shutting down operations. Ceteris paribus, a reduction in network hash rate is similar to increasing the effective price of Bitcoin for miners. In fact, the post-halving reduction in network hash rate can be thought of as a ~27.6% increase in the price of the Bitcoin for the surviving miners. [c] Mining equipment: The changed economics of BTC mining post-halving have made a good fraction of existing mining hardware unprofitable to run. Data from <a href="https://www.asicminervalue.com/">AsicMinerValue</a> shows 45 older generation Bitcoin miners as now being unprofitable. In fact, Antminer S9’s, which account for a large share of existing network hash rate, are unprofitable after the halving. The drop in hash rate indicates that shutting down of inefficient mining equipment is already underway. [caption id="attachment_25029" align="aligncenter" width="1170"]<figure class="kg-card kg-image-card"><img src="http://static.delta.exchange/wp-content/uploads/2020/05/ch6.png" class="kg-image" alt loading="lazy" width="1170" height="527"></figure>Source: AsicMinerValue.com[/caption] So, What’s To Come?A network halving starts a new CAPEX cycle for miners as they look to move to newer, more efficient mining devices to reduce the cost of producing Biitcoin. Since the halving is known well in advance with complete certainty, we believe that that hardware upgrade cycle would have started a few months in advance, with large mining pools taking the lead here. Marginal players may get forced out of the market and will get replaced by new entrants who are not encumbered by legacy hardware. That is when we will see the resumption of a broad uptrend in network hash rate. The adjustments through the above mentioned dimensions will occur over the next few months. These three dimensions certainly interact with each other - for example, if price goes up, there is lowered pressure to upgrade mining devices or to exit the industry due to mining inefficiencies. Conversely, a fall in the price of Bitcoin will force otherwise efficient miners to be forced to shut down. An increasing hash rate forces continuous efficiency improvements and vice versa. As such, it will be highly interesting to observe the evolution of the Bitcoin mining industry over the next few months.<hr>Delta DevelopmentsThe Delta Podcast Is Here!We're proud to announce the launch of our Delta Podcast series! 🎤<figure class="kg-card kg-image-card"><a href="https://youtu.be/JKdWyXV2EuA"><img src="http://static.delta.exchange/wp-content/uploads/2020/05/Youtube-1.jpg" class="kg-image" alt="Delta Exchange Podcast with Whalepool" loading="lazy" width="1280" height="720"></a></figure>In our first episode, Delta co-founder Pankaj Balani discusses everything from cryptocurrency derivatives to traditional financial markets, and the effects of the global COVID19 pandemic with members of the Whalepool team.
