As we approach the halfway mark of 2023, the Bitcoin network is drawing closer to a significant event: the imminent halving of block rewards, set to occur in approximately 300 days. Predictions suggest that this momentous occasion will take place between April 21 and 27, 2024, resulting in a substantial 50% reduction in mining participants’ earnings. Such a development is expected to bring about a significant transformation in the mining landscape, as miners will witness a significant decrease in the amount of bitcoin they receive compared to previous cycles.
Balancing Act: Can Bitcoin’s Halving Ensure Sustainable Mining Rewards and Network Security?
With a mere nine months remaining until the Bitcoin halving, the mining industry faces a formidable challenge – a substantial decrease in revenue, especially if market prices remain stagnant or decline. Historically, the price of bitcoin (BTC) has experienced a significant surge approximately six months to a year before the halving event.
In the past six months alone, bitcoin (BTC) has surged by over 80% in 2023. Currently, around 900 brand new bitcoins enter the market each day (144 blocks), generating a daily sum of approximately $26 million for miners, alongside transaction fees, based on the current exchange rates.

However, in a mere nine months, if prices were to remain within the same range, mining participants would witness a sharp decline, earning a reduced daily amount of $13 million, in addition to fees. Statistics reveal that miner fees have only accounted for a small portion of the revenue earned by bitcoin miners.
Bitcoin miner revenue per month, as reported on theblock.co/data/on-chain-metrics on July 7, 2023.
Data from July 7, 2023, shows that fees represented 1.89% of the earnings generated from 144 blocks. In June, bitcoin miners collectively earned $783.76 million in revenue, with block rewards alone (excluding fees) amounting to $745.45 million. In May, miners acquired a total of $919.22 million in revenue, with $793.3 million coming from the block subsidy, according to the data.

The fees collected in May reached $125.92 million, a relatively high figure considering fees had not exceeded $20 million per month from December 2021 until March 2023. Although fees reached $246 million in April 2021, the increase compared to May was only $121 million. The highest monthly fee revenue earned by miners to date was in December 2017 when they amassed $297 million.

A low fee ratio carries several implications for the network’s long-term sustainability as rewards decline with each halving. Some proponents argue that fees must rise to achieve a higher fee-to-rewards ratio to mitigate potential issues. As the block reward diminishes, bitcoin miners may become less incentivized to participate in network activities, especially if mining costs exceed potential rewards.
Reduced mining participation could lead to a decline in hashrate, increasing the network’s vulnerability to potential attacks such as a 51% attack. Larger mining operations might become the sole entities capable of sustaining mining activities, potentially concentrating power in the hands of a few. If smaller miners exit the market, two potential solutions to compensate for the lack of hashpower arise: either the price of bitcoin must significantly increase or the mining difficulty must decrease proportionally.
The 2024 halving will test these theories more than any previous halving. This time, the reward will decrease from 6.25 BTC to 3.125 BTC per block after the halving. Following the halving, the annual inflation on the Bitcoin network will drop from the current 1.7% to 0.84%. If the hashrate declines due to the next halving, block intervals are likely to remain at an average of 10 minutes when the network difficulty adjusts to the lower hashrate.
Whether it’s the 2024 halving or subsequent ones, the supply of bitcoins remains finite at 21 million, making it necessary for the low fee ratio to rise and compensate miners. To address these concerns, finding a balance between reducing the block reward and ensuring adequate incentives for miners becomes crucial for the Bitcoin network. This equilibrium may involve factors such as transaction fees, network scalability, and overall adoption to maintain the network’s long-term sustainability and security.

Frequently Asked Questions (FAQs) about Bitcoin halving
Q: When is the Bitcoin halving event expected to occur in 2024?
A: The Bitcoin halving event is projected to take place between April 21 and 27, 2024.
Q: What is the impact of the halving on mining rewards?
A: The halving results in a significant reduction of 50% in mining earnings, meaning miners will receive half the amount of bitcoin compared to previous cycles.
Q: How does the price of bitcoin typically behave before the halving?
A: Historically, the price of bitcoin experiences a surge approximately six months to a year before the halving event.
Q: What percentage of miner revenue comes from fees?
A: According to the data from July 7, 2023, fees accounted for 1.89% of the earnings generated from mining blocks.
Q: What are the implications of a low fee ratio on the network’s sustainability?
A: A low fee ratio raises concerns about the long-term sustainability of the network as rewards decrease with each halving, potentially leading to decreased mining participation and a decline in network security.
Q: What solutions are suggested to compensate for a potential decline in mining participation?
A: If smaller miners exit the market, the two potential solutions are either a significant increase in the price of bitcoin or a decrease in mining difficulty to maintain hashpower and network security.
Q: What changes are expected with the 2024 halving?
A: The reward per block will decrease from 6.25 BTC to 3.125 BTC, resulting in an annual inflation drop from 1.7% to 0.84% on the Bitcoin network.
Q: How can the Bitcoin network ensure the balance between reducing block rewards and incentivizing miners?
A: Maintaining a balance involves considering factors such as transaction fees, network scalability, and overall adoption to ensure the long-term sustainability and security of the network.
