Bitcoin miners are struggling to pay the bills. This disparity underscores a grim truth: Bitcoin's long-term viability is at risk. While Bitcoin's continually increasing hashrate is usually touted as an indication of the network's well-being — even during chaotic markets — it provides only half the picture. Just as significant, and much more alarming, is the way that hashpower is allocated. 

Summary

Small miners are under increasing pressure — growing energy expenses, unstable markets, and competition from capital-intensive mining behemoths cut them down to size.

Large companies have fat cushions — renewable energy contracts, international diversification, and forays into AI data centers sustain them through market slumps.

Merged mining is a lifeline — it allows independent miners to profit from multiple blockchains without additional energy or hardware, increasing margins during difficult cycles.

Decentralization relies on small miners — maintaining varied participation through merged mining enhances Bitcoin's resistance to centralization.

With the bear market continuing, small and medium-sized miners are under increasing pressures due to the hike in costs, geopolitical instability, and unrelenting competition from well-funded mining behemoths. Amid this scenario, merged mining — an approach that enables miners to secure other blockchains with the same infrastructure while it mines for Bitcoin — is now a lifesaver. By making new streams of revenue accessible without extra energy or hardware expenses, merged mining aids in maintaining the profitability of stand-alone miners, hence supporting the decentralized base that the Bitcoin network relies on.

Large mining corporations vs. Part-time miners

Major mining firms have leveraged their size and corporate footprint to achieve fundamental advantages over smaller operators and independent miners — particularly to weather difficult market cycles — and leave smaller independent operators struggling to follow. Whereas independent miners may rely on razor-thin margins, large mining firms possess the size, capital, geographic extent, and ability to adopt advanced treasury management and hedging techniques that immunize them from entire market cycles.

Consider mining behemoth MARA Holdings, for instance. The company has pursued renewable energy expansion aggressively, snapping up a large Texas facility and signing a landmark agreement with the Kenyan government to both enhance renewable energy output and create a renewables-driven mining facility. By diversifying among jurisdictions and gaining entry to low-cost, renewable power, Marathon can hedge against the type of energy price shocks that could force smaller mining operations out of business.

Some companies are even taking it one step further, venturing into completely new sectors. In February, Riot Platforms revealed it will construct AI data centers — diversifying into artificial intelligence infrastructure to make hay from the exploding demand for high-end computing. These new sources of revenue, largely unlinked from Bitcoin or crypto markets, provide Riot with another cushion in a downturn and lessen the company's vulnerability to Bitcoin's price performance in isolation.

Major mining operators are also in a special position to negotiate direct agreements with power producers — something a small, independent miner cannot. Often, they can get good energy rates or tax credits from regional governments that want high-tech facilities. Riot Platforms, for example, has garnered almost $136 million in power credits from the Texas grid operator since 2022. These benefits, in addition to scale of operations, enable large companies to survive downturns that would be disastrous for smaller, independent miners with less choice and slimmer margins.

Independent miners are not so fortunate. They have to endure high electricity bills, fluctuating energy rates, and high tariffs on mining equipment — costs fueled by the current market uncertainty and an impending trade war. These increasing pressures risk pushing independent miners out of business, concentrating hashpower in the hands of a few, well-placed companies, and raising questions about the decentralization of Bitcoin. 

Merged mining provides independent miners with a lifeline

Merged mining has quietly become a potent force for individual miners seeking to remain competitive. Essentially, merged mining enables miners to utilize the same computationally intensive work that they do to secure Bitcoin in order to mine other blockchains compatible with Bitcoin — without the use of any extra power or equipment. This process essentially makes possible a redundant stream of income, allowing miners to receive rewards from several networks at the same time.

For independent and small-scale miners, this supplemental revenue can be the distinction between closure and remaining online. It buffers the blow of Bitcoin's unpredictable block rewards, providing a steadier monetary base through long-term declines or post-halving tightenings. By boosting revenue without boosting operational expense, combined mining allows to equalize the playing field — providing smaller miners with a means to stay competitive even as larger companies concentrate more power.

Smaller miners also possess a specific operational advantage. They're generally more agile than institutional competitors, enabling them to embrace approaches such as merged mining quicker and without bureaucratic inertia. Major mining companies are hemmed in by complicated infrastructure, but independent miners can change direction quicker — retooling their configurations and experimenting with new protocols on the fly.

In most instances, these smaller operators are closer to the metal: hands-on, experimental, and intent on getting every ounce of value they can. That nimbleness allows them to move very quickly, make subtle adjustments to merged mining setups, and seize returns that large operations might miss.

In a world where every fraction counts, merged mining isn't merely an efficiency — it's a lifeline. And in a decentralized network like Bitcoin's, the survival of small, independent miners isn't merely good for competition. It's crucial to the ecosystem's well-being.

An important aspect of Bitcoin's long-term viability

Variety miner involvement is Bitcoin's greatest protection against centralization. When authority over mining is held within the hands of fewer large, corporate players, the network is more vulnerable to censorship, manipulation, and outside political interference.

While price volatility continues and competition grows, it's time for the Bitcoin ecosystem — developers, miners, and enthusiasts alike — to wholeheartedly adopt merged mining as a fundamental pillar of the network's sustainability. Enabling small miners isn't a question of fairness or sentiment; it's critical to Bitcoin's long-term sustainability as a genuinely decentralized, worldwide financial system.
