Mining Profitability Deteriorates: Theoretical vs. Actual Revenue Gap Reaches 136%
The Bitcoin mining industry is currently undergoing its most complex structural adjustment since the protocol's inception. While the BTC price holds around $61,000 and the network hashrate is near 1 ZH/s — close to an all-time high — miner profitability continues to worsen. Data shows that at the current hashrate level, the theoretical daily revenue for all miners should be about $78 million. However, actual daily revenue is only around $33 million, a staggering 136% shortfall. This gap indicates that miners are not only facing the pressure of declining block subsidies but also struggling with an incomplete transition to a fee-driven revenue model.
Transaction fee income remains a critical pain point. The average daily fee revenue across the network is just $220,000, far below the historical implied level of approximately $9.7 million. As halving events progressively reduce the pace of new coin issuance, fee income is expected to become a larger share of miner revenue, but that transition has yet to materialize. Miners remain heavily reliant on block rewards, making them vulnerable to any further reduction in subsidy.
Rising Costs and Breakeven Pressures: The 2028 Halving Will Accelerate Industry Shakeout
Beyond the revenue side, cost pressures are mounting steadily. According to a report by BIT on Target, total Bitcoin miner revenue in 2025 was approximately $17.2 billion, of which electricity costs alone accounted for $12.3 billion — representing 71.5% of total revenue. Global investment in mining hardware totaled around $4.5 billion. Combining these figures, the industry-wide breakeven price is estimated at roughly $65,000. At the current BTC price of $61,000, most miners are operating near or below the breakeven point, making it difficult to sustain healthy profits from mining alone.
Looking ahead to the next halving in 2028, the lower bound of Bitcoin's production cost is projected to rise to about $93,289. This level would effectively eliminate smaller, less efficient miners and accelerate consolidation toward large, well-capitalized firms with access to low-cost power and diversified revenue streams. The report notes that many mining companies are already transforming from pure Bitcoin producers into infrastructure operators, energy providers, and AI/HPC computing infrastructure hosts. The competitive focus is shifting from raw hash rate expansion to business model upgrades and balance sheet strength. Miners with captive low-cost energy, AI/high-performance computing hosting capabilities, and stronger capital management are likely to gain a decisive advantage in the next cycle.
These insights are drawn from the full BIT on Target report, which further details how miners can navigate the coming shakeout. As the 2028 halving approaches, the real reckoning for Bitcoin mining has only just begun.
