Bitcoin Mining: MARA Revises Strategies Amid Environmental Pressures, Competition, and Record Res...

In a context of strong competition and increasing technical difficulties, MARA Holdings revamps its strategy. With growing production and over 50,000 BTC in reserve, the company consolidates its global leadership.

But the future of mining is increasingly tied to sustainability, energy efficiency, and smart financial management.

Production is growing, but the difficulty does not slow down

In July 2025, MARA produced 1,176 bitcoin, resulting from 179 blocks mined, an increase compared to the previous month. According to CEO Fred Thiel, the performance should be viewed in light of:

a constantly increasing global hashrate, which raises the bar of competition;

an increase in the difficulty of mining by 9% in the last month, which reduces the chances of success even for the most structured operators.

According to the official data from MARA Holdings, each increase in difficulty results in higher consumption and operational costs.

At the end of July, MARA held over 50,000 BTC between liquid reserves and assets used as collateral. This approach allows the company to:

strengthen financial solidity;

ensure immediate liquidity and access to credit;

finance new projects and R&D activities flexibly.

According to GlobeNewswire, MARA is today the second largest holder of BTC among publicly traded companies.

The hashrate of MARA has grown from 50 EH/s to 58.9 EH/s, with a 3% monthly increase. However, the increase in computing power does not guarantee proportional returns.

Note: even the big players are subject to fluctuating performance in an ecosystem that evolves rapidly.

The profitability issue: energy costs and plants under stress

The increase in difficulty makes mining increasingly expensive. To maintain sustainable margins, MARA continues to:

invest in more efficient hardware;

dynamically manage resource allocation;

apply energy containment strategies, such as scheduled interruptions (curtailment) in Ohio.

Mining today requires not only power, but strategic adaptability.

Active management of reserves represents a strength for MARA:

use of BTC as collateral for lines of credit;

liquidity exceeding 5 billion dollars;

capital raised through issues for almost 1 billion in 2025.

As reported by Investing.com, this is an exemplary model of crypto-finance management.

Texas and sustainability: mining becomes (more) green

In 2025, MARA will launch a new 25-megawatt data center powered by excess natural gas from fields in Texas and North Dakota.

Objective: reduce waste and environmental impact, while not exclusively using renewable sources.

The project, described on mara.com, aims for greater sustainable efficiency in the production chain.

In a sector marked by volatility, technological competition, and environmental constraints, MARA’s integrated approach — among strategic reserves, hardware innovation, operational flexibility, and environmental focus — represents an example to monitor.
