On December 25, 2023, the Bitcoin network achieved an important milestone. Mining hash rate, a measure of a network’s computing power, hit an all-time high of 544 exahashes per second (EH/s). This landmark event, confirmed by Blockchain.com, marks a remarkable 130% increase since January 2023, when the hash rate was 253EH/s.
This surge in hashrate has coincided with a notable rise in the price of Bitcoin, which has risen more than 150% since early 2023.. However, the rise in hashrate has created serious difficulties for miners. The increase in competition and computing power required to mine Bitcoin has made the process more difficult. A high hash rate is beneficial for the theoretical pricing model, but it is a challenge for miners, who must expend more effort and resources to secure the next block.
Despite record hash rates, miners’ profitability is declining. Hash prices, a key indicator of revenue per terahash per second per day, have fallen sharply. It decreased by 34% from a high of $0.136/TH/s/day in December to $0.09/TH/s/day. This decline in profitability is due to the declining enthusiasm surrounding the BRC-20 ordinal inscription and continued rising fee pressure from the Bitcoin mempool, which has not been fully liquidated in almost a year.
The increase in hashrate and the resulting decline in profitability will have a significant impact on the Bitcoin mining industry. Large-scale mining operations with access to cheaper electricity and more efficient mining equipment can overcome low profitability. However, smaller miners or those with high operating costs may find it increasingly difficult to remain profitable. This could further centralize mining power in the hands of a few large players, potentially impacting the decentralized nature of the Bitcoin network.
If the price of Bitcoin continues to rise, it could offset some of the difficulties faced by miners due to falling hash prices. Additionally, technological advancements in mining hardware can improve efficiency and profitability. However, cryptocurrency market volatility and regulatory changes remain major factors that could affect the future of Bitcoin mining.
