Bitcoin Hashrate Reaches All-Time High of 769.8 EH/s Amidst Decreasing Mining Profitability

The hashrate of the Bitcoin network, an essential measure of its security and computational strength, achieved a new record of 769.8 exahashes per second (EH/s) on October 21.

This increase in hashrate indicates enhanced security for the Bitcoin blockchain, as greater computational power enhances the network’s resistance to potential attacks.

According to data from BitInfoCharts, the Bitcoin hashrate has been on a consistent upward trajectory since 2021, primarily fueled by innovations in mining hardware, especially the emergence of application-specific integrated circuits (ASICs).

These specialized devices have greatly improved the efficiency and capability of Bitcoin mining operations.

Increasing Hashrate Presents Challenges for Miners

Nonetheless, the growing hashrate introduces difficulties for miners.

As the mining difficulty for Bitcoin escalates, so too does the expense associated with mining.

This situation could particularly affect smaller mining operations due to the Bitcoin halving, which has decreased block rewards, thereby further tightening profit margins.

Nazar Khan, co-founder and COO of TeraWulf, highlighted the necessity of energy-efficient infrastructure for miners to navigate these challenges successfully.

He pointed out that companies with access to inexpensive energy and advanced mining equipment would hold a considerable advantage following the halving.

TeraWulf, recognized as one of the largest Bitcoin mining firms globally, is strategizing to continue its growth despite the anticipated decrease in block rewards.

In spite of the increasing difficulty, Bitcoin miners have been prudent regarding the sale of their assets.

Data from CryptoQuant indicated that on October 20, mining companies transferred only 2,916 BTC to centralized exchanges, representing one of the lowest selling volumes in the past month.

Bitcoin Mining Profitability Declines in September

According to a research report from Jefferies, Bitcoin mining profitability fell in September compared to the prior month.

The investment bank noted that the average daily revenue per exahash decreased by 2.6% from August figures.

Jefferies analysts Jonathan Petersen and Joe Dickstein cautioned that October might prove to be even more difficult, even as the network’s hashrate increased by 11%.

The report also disclosed that publicly listed mining companies in North America grew their share of the Bitcoin network, accounting for 22.2% of total mining activity in September, up from 19.9% in August.

This rise was partially attributed to enhanced uptime for these companies, which benefited from cooler weather conditions.

Among the leading performers, Marathon Digital (MARA) mined the highest amount of Bitcoin in September, generating 705 tokens, followed by CleanSpark (CLSK) with 493 tokens.

Marathon’s installed hashrate remained the largest in the sector, reaching 36.9 exahashes per second (EH/s) at the close of September, while Riot Platforms (RIOT) held the second position with 28.2 EH/s.

In August, investment firm Bernstein issued a positive outlook on the Bitcoin mining industry, assigning “outperform” ratings to four publicly traded companies, including Riot Platforms, CleanSpark, IREN, and Core Scientific.

As reported, IREN is currently facing a class-action lawsuit from investors who claim the cryptocurrency mining firm misrepresented its high-performance computing (HPC) capabilities.

The primary allegation of the lawsuit is that IREN’s Childress facility was depicted as an HPC-ready data center, which it allegedly was not.
