The Bitcoin Hash Rate Explodes : Are Miners in Trouble ?

Bitcoin mining (BTC) is undergoing an unprecedented transformation. The latest data reveals that the global hash rate of the network has shattered all records

Bitcoin mining (BTC) is undergoing an unprecedented transformation. The latest data reveals that the global hash rate of the network has shattered all records, surpassing the symbolic milestone of 1 Zetahash per second (ZH/s) for the first time.

This computing power not only enhances the security of the blockchain but also presents American miners with a critical dilemma, exacerbated by new tariffs on their imported equipment.

The numbers speak for themselves. According to mempool.space, the hash rate flirted with 1,025 ZH/s, while BTC Frame and Coinwarz report respective peaks of 1.02 ZH/s and 1.1 ZH/s in early April 2025.

This escalation reflects a performance race among global miners, making block validation – and the BTC rewards that come with it – increasingly challenging. For industry players, each additional terahash complicates the profitability equation, especially in regions where energy and equipment costs are high.

USA Dominance in the Sector

The United States currently dominates the mining landscape. According to Mathew Sigel, an analyst at VanEck, American publicly traded companies control 30% of the global hash rate, a share that has increased by 800 basis points since the last halving.

However, this supremacy is wavering. Recent trade measures by the Trump administration impose high tariffs on ASICs, specialized machines mainly from Asia. The result is a surge in costs that undermines the margins of local operators.

Profitability Endangering the Bitcoin Network

The situation is alarming. Pierre Rochard, a former executive at Riot Platforms, notes a decline in marginal revenue per megawatt-hour, dropping from $200 to $150 in 2025 for the most efficient equipment. This erosion is due to an explosive hash rate, a declining Bitcoin trading at around $77,000 after a 10% drop over 30 days, and rising import costs. American miners, already fiercely competitive, see their economic model threatened.

Tariffs have MASSIVE implications for Bitcoin Miners.Except off-shore supply to get squeezed, increasing demand for on-shore miners.If this is coupled with a BTC run we could see ASIC prices rip 5 to 10x like they did in 2021.See this slide from the BlockwareTeam 2025… https://t.co/IZk6dIa3xW pic.twitter.com/Y16uEJM7i5

To cushion the blow, some have opted for urgency by massively importing ASICs before the tariffs kick in. A short-term fix. Long-term solutions involve innovations: producing machines locally, forming partnerships with non-Chinese manufacturers, or leveraging renewable energies to reduce the electricity bill. Only the most agile will survive.

Moreover, some miners have turned to collaboration with AI companies to share computing power from their mining farms. An innovation that could allow Bitcoin to benefit from another thriving sector.

But this mix of records and constraints could reshape the Bitcoin mining landscape. While the United States took the lead after the 2021 exodus of Chinese miners, their position is now on borrowed time.

Experts predict consolidation, with giants like MARA Holdings (50 EH/s) ready to absorb the weaker players. Yet, miners’ enthusiasm remains unwavering. This paradox – a soaring hash rate amid a tumultuous market – illustrates the unwavering faith in Bitcoin’s potential, even at the cost of a brutal adaptation. And particularly to the detriment of small Bitcoin miners. A tough blow for the network’s decentralization.
