Bitcoin is a decentralized Cryptocurrency that is based on a network of nodes that validate transactions and maintain consensus. The nodes that are in charge of creating new blocks and receiving a reward for it are called miners. Miners use specialized equipment that consumes a lot of electricity to solve complex mathematical problems and compete for the right to add the next block to the chain.
The Bitcoin protocol is designed to adjust mining difficulty every 2,016 blocks or roughly every two weeks, maintaining an average interval of 10 minutes between blocks. Additionally, the protocol states that the block reward is halved every 210,000 blocks or approximately every four years, to limit the total Bitcoin supply to 21 million. This event is known as “Halving”.
What is Halving and what consequences does it have on Bitcoin?
Halving is a deflationary mechanism that aims to preserve the value of Bitcoin against inflation. By reducing the supply of new bitcoins, Halving increases the scarcity of the Cryptocurrency and if demand holds or grows, so does its price. Halving also affects miners, since it decreases their income and forces them to be more efficient in order to remain profitable.
The last Bitcoin halving occurred on May 11, 2020, when the number of blocks reached 630,000. At that time, the block reward went from 12.5 to 6.25 bitcoins. The price of Bitcoin on the day of the halving was about $8,600, and 150 days later it had risen to about $10,800. The hash rate, (a measure of network processing power), also hit an all-time high of about 157 ExaHashes per Second (EH/s) in October 2020.
However, the situation changed dramatically in May 2021, when China announced a crackdown on Cryptocurrency mining and trading, causing the price and hash rate of Bitcoin to drop. China was home to around 70% of the world’s Bitcoin mining power, until a crackdown forced many miners to shut down their operations or relocate abroad. The Bitcoin price fell to around $30,000 in June 2021, and the hash rate plummeted to around 58 EH/s in July of the same year.
This massive exodus of miners has provided both a challenge and an opportunity for the Bitcoin ecosystem. On the one hand, it has reduced the security and speed of the network, since more time and confirmations are needed to validate transactions. On the other hand, it has opened the door to new entrants and markets, which can take advantage of less competition and less difficulty to get into the game. Some of the most popular destinations for miners are the United States, Kazakhstan, Russia and Canada.
The next halving and how the miners prepare.
The next Bitcoin halving is expected to occur in April 2024, when the number of blocks reaches 840,000. At that time, the block reward will be reduced to 3,125 bitcoins per block mined. By then, miners will have to have adapted to the new market conditions and found cheap and sustainable energy sources to keep operating. They will also have to face increasing competition from other Cryptocurrencies that use alternative mechanisms to Bitcoin’s Proof-of-Work (PoW) system, such as Proof-of-Stake (PoS) or Proof-of-Authority (PoA).

The 2024 halving will be a pivotal event for the future of Bitcoin, as it will determine its ability to remain the leading Cryptocurrency in terms of capitalization, adoption, and innovation. If the halving manages to boost the price and demand for Bitcoin, as it has on previous occasions, it could cement its position as a store of value and a global medium of exchange. If the halving causes a profitability crisis and a loss of confidence in the network, it could give way to other more efficient and scalable alternatives. Only time will tell.
In summary, the article explains the current situation of Bitcoin miners and the upcoming halving of 2024. The halving is an event that halves the block reward miners receive for creating new blocks on the Bitcoin network. Halving aims to control inflation and increase the value of the Cryptocurrency, but it also affects the profitability and competitiveness of miners. The last halving occurred in May 2020, and the next one is scheduled for April 2024. Since the last halving, miners have had to deal with various challenges, such as a crackdown from China, falling price and hash rate, and migration to other countries and energy sources. The 2024 halving will be a defining moment for the future of Bitcoin, as it will determine its ability to remain the leading Cryptocurrency or give way to other alternatives.
