Marathon Digital Mines 462 Bitcoin in January as Network Hashrate Surges Past 190 Exahash

The Hardware/Software Landscape

January 2022 marked a pivotal month for Bitcoin mining infrastructure as major publicly traded miners aggressively scaled operations despite a correcting market. Marathon Digital Holdings, one of the largest enterprise Bitcoin self-mining companies in North America, produced 462.1 self-mined bitcoin during January — a staggering 816% increase from the 50.4 bitcoin mined in January 2021. The company received approximately 21,000 top-tier ASIC miners from Bitmain during the month alone, bringing its total delivered fleet to approximately 93,000 units.

Marathon’s active mining fleet as of February 1, 2022, consisted of 32,710 deployed miners producing approximately 3.6 EH/s. The company had begun installing miners in containers at Compute North’s new facilities — predominantly behind the meter at wind and solar farms — including a massive 280-megawatt site in west Texas. Marathon expected to have all 199,000 purchased miners deployed by early 2023, targeting a total hashrate of approximately 23.3 EH/s.

Meanwhile, HIVE Blockchain Technologies reported its own January production figures, having mined 264 BTC with a hashrate of 1.87 Exahash — a 10% month-over-month increase in Bitcoin mining capacity. HIVE also maintained significant Ethereum mining operations, producing 2,170 ETH equivalent during the month from 4.56 Terahash of Ethereum mining capacity. The company’s total Bitcoin equivalent production reached 425 BTC for January, averaging 13.7 BTC equivalent per day.

Hashrate & Difficulty

The total Bitcoin network hash rate surged approximately 14% during January 2022, crossing the 190 Exahash threshold for the first time. This rapid increase in computational power dedicated to the network reflects the ongoing deployment of next-generation ASIC miners across the industry, even as Bitcoin’s price remained well below its November 2021 peak of approximately $69,000.

Bitcoin mining difficulty increased by roughly 10% during the month, while Ethereum network difficulty climbed approximately 7.5%. These upward adjustments in difficulty reflect the competitive nature of proof-of-work mining and the continued capital expenditure by major operations despite tighter profit margins at prevailing prices.

The difficulty increases directly impacted miner profitability. Marathon noted that its January production was partially constrained by the rising network hash rate, in addition to ongoing maintenance issues at the power generating station in Hardin, Montana. CEO Fred Thiel acknowledged the impact, stating that operations would become more stable as the company accelerated deployments with Compute North.

Profitability Metrics

With Bitcoin trading at approximately $38,138 on January 29, 2022, mining economics remained under pressure compared to the heady days of late 2021. Marathon’s total bitcoin holdings stood at approximately 8,595 BTC with a fair market value of roughly $330.6 million. The company’s cash position was approximately $189.1 million, yielding total liquidity of about $519.7 million. Marathon had not sold any bitcoin since October 21, 2020, maintaining a strict accumulation strategy.

HIVE Blockchain held 2,043 Bitcoin and 25,404 Ethereum as of January 31, 2022. The company’s green energy-powered operations across Canada, Sweden, and Iceland provided some cost advantages, though HIVE noted that extremely cold weather in Canada forced Quebec Hydro to curtail approximately 100 hours of energy consumption under a seasonal curtailment agreement. Additionally, HIVE experienced expected temporary seasonal rises in energy prices at its New Brunswick facilities.

For smaller miners without access to institutional-scale power contracts or green energy infrastructure, the combination of rising difficulty, depressed prices, and increasing energy costs created significant headwinds. The gap between efficient large-scale operators and smaller participants continued to widen throughout January.

Environmental Impact

The sustainability narrative around Bitcoin mining continued evolving in January 2022. Marathon’s partnership with Compute North emphasized behind-the-meter facilities at wind and solar farms, reflecting a broader industry shift toward renewable energy sources. HIVE explicitly marketed its green energy strategy, operating data centers powered by hydroelectric, geothermal, and other renewable sources.

However, the industry’s total energy consumption grew in lockstep with the hash rate increase. The 14% jump in network hash rate during January implied a corresponding increase in electricity consumption across the global mining network. The tension between Bitcoin’s energy demands and environmental concerns remained a defining issue for the industry’s public perception and regulatory outlook.

Quebec Hydro’s curtailment of mining operations highlighted an often-overlooked aspect of green mining: even renewable-powered facilities face seasonal constraints. The cold weather that drove up heating demand simultaneously reduced available power for industrial consumers like crypto miners, demonstrating the complex interplay between climate, energy markets, and mining operations.

Strategic Outlook

January 2022’s mining landscape suggested an industry in transition. The aggressive expansion plans by Marathon and HIVE — despite falling Bitcoin prices — reflected confidence in long-term profitability and the strategic value of building hash rate during market downturns. Marathon’s target of 23.3 EH/s by early 2023 would represent a more than six-fold increase from its current 3.6 EH/s, fundamentally reshaping its competitive position.

The industry was clearly moving toward consolidation and professionalization. Companies with strong balance sheets, access to cheap renewable energy, and the ability to rapidly deploy new ASIC hardware were positioning themselves to weather the ongoing market correction. Those without such advantages faced increasingly difficult economics as difficulty continued its upward trajectory.

The Federal Reserve’s signaling of interest rate hikes added macroeconomic pressure to the mining sector. Rising rates typically compress valuations for risk assets and increase financing costs for capital-intensive mining operations. The months ahead would test whether the hash rate growth trend could sustain itself under tightening monetary conditions.
