🧊 Bitcoin Miners Struggle with Rising Difficulty in January

In January, most Bitcoin miners experienced a decline in monthly production as network difficulty continued to rise. For instance, Hut 8 saw a significant 27% drop in production, mining only 65 BTC in January compared to the previous month. MARA and Bitfarms also recorded drops of 12.5% and 4.7%, respectively.

However, Riot Platforms bucked the trend by achieving a 2.1% increase in Bitcoin production. This growth was largely driven by the launch of a new mining facility in Texas, which contributed to the deployment of a hash rate of 15.7 EH/s by the end of January.

The new facility is part of a large-scale 1 GW development for Bitcoin mining, designed to scale operations and improve production efficiency. Riot's CEO, Jason Les, noted that the company has seen strong results from newly deployed miners and immersion cooling systems, which have boosted their operational hash rate and utilization rates.

As for other miners, many have been preparing for rising network difficulty by upgrading their equipment and streamlining their operations. Despite the difficulties faced in January, Hut 8's CEO, Asher Genoot, mentioned that the company was nearing the completion of infrastructure upgrades, which are expected to enhance mining capacity in the coming weeks.

The overall Bitcoin network difficulty reached an all-time high of 110 T throughout January, reflecting a 27.8% increase since the halving event in April 2024. While mining difficulty saw a slight drop to 108 T in the last week of January, miners are still dealing with high hashrates, which reached around 832 EH/s.

This environment has led to some concerns over declining hashrates and fewer preorders for mining hardware, as the industry adapts to the challenges posed by increased competition and energy costs.
