Bitcoin Miners Rake In $1.66B in August

In August, bitcoin miners generated revenues close to 1.65 billion dollars, a level almost identical to that of July. This maintenance reflects an impressive resilience of the sector, despite a context marked by rising costs and energy pressure. But behind this apparent stability lie structural vulnerabilities that raise questions: can the current mining model really hold in the long term?

Bitcoin Miner Revenues Hold Steady in August

Since late June 2025, the Bitcoin network has experienced a gradual increase in activity. In August, bitcoin miners generated between 1.633 and 1.66 billion dollars, almost the same amount as in July.

This stability confirms the solidity of their revenues, despite an environment still marked by strong competition and high energy costs.

Figures compiled by Newhedge and The Block show that block subsidies remain the backbone of this profitability.

Transaction fees, although modest in absolute value, around 1.30 dollars per transfer on average, are gaining importance. They now represent nearly 1.9% of total rewards, compared to less than 1% a few months ago.

This progress reflects growing activity on the blockchain. The mempool, a gauge of network congestion, showed between 85,000 and 93,000 pending transactions at the end of August, a sign of persistent bottlenecking.

In the short term, this dynamic supports miners’ revenues. But it also highlights their strong dependence on the intensity of on-chain exchanges, which is itself closely linked to market cycles and speculative movements driving the Bitcoin ecosystem.

Between Resilience and Vulnerability, a Model Under Pressure

While August confirms the solidity of mining revenues, the sector remains under pressure. Margins remain 40 to 50% lower than the pre-halving period of April 2024. Network difficulty continues to rise. 

This forces less competitive miners to seek solutions: energy optimization, pooling of hashrate, or relocation to low-cost areas.

In this context, bitcoin’s price, stabilized around 113,000 dollars, provides some support. However, it is not enough to offset the structural decline in profitability caused by the halving.

Miners thus find themselves in a paradoxical situation: their revenues appear stable on paper but remain fragile in the face of market uncertainties and energy costs.

The future of mining therefore rests on an essential triptych: the price of bitcoin, network difficulty, and the regulatory framework. As long as these three parameters remain uncertain, the sector’s profitability will remain under pressure.

In short, August thus illustrates the impressive resilience of miners, but also highlights a fundamental vulnerability: without a new upward impulse in bitcoin prices or major technological advances in energy, the sustainability of the mining model remains threatened.
