Can Bitcoin's Fee Market Sustain Miners?
For now, it cannot. At present, the Bitcoin fee market is completely unable to sustain miners. By June 2026, average daily network transaction fees had fallen to less than $250,000, accounting for under 1% of total miner revenue. Approximately 20% of miners are already operating at a loss.
Core Data: Fee Ratio Hits All-Time Low
On-chain data from June 25, 2026 shows that Bitcoin miners' 7-day average daily revenue is around $30 million, while daily transaction fee contributions have dropped below $250,000, less than 1% of total income.
Compare two key moments:
September 2024: Transaction fees accounted for only 1.6% of miner revenue (around $399,000 from fees out of $25.35 million daily income).
2024 Halving Day: The Runes protocol frenzy drove single-day fee revenue to 1,257.7 BTC (worth approximately $81.75 million), exceeding 75% of total miner revenue.
The implication: the current fee market's support for miners has plunged from "occasional highlights" to "nearly negligible."
Why the Fee Market Is So Depressed in 2026
A research report released by Galaxy Digital in August 2025 broke down the situation in detail:
About 15% of blocks are "free blocks" — where the average transaction fee within the block is ≤1 sat/vbyte. Such blocks were almost non-existent in 2024.
Nearly 50% of blocks are not full — total block weight falls below 3.9 million (limit is 4 million), indicating the mempool is often empty. When the network lacks transactions, miners cannot earn fees even if they want to.
The direct cause of the fee collapse is the retreat of non-monetary transactions. From Q2 to Q3 2024, Runes and Ordinals-related transactions once accounted for 40-60% of daily network transactions; by August 2025, it had dropped to about 20%. When these "willing to pay high fees" transactions vanish, the entire fee market collapses with them.
Miners' Actual Predicament: Revenue Below Cost
JPMorgan estimates the average Bitcoin production cost at around $78,000, while Bitcoin's price has been below this level for five consecutive months — the longest stretch this cycle. About 20% of miners are already operating at a loss.
Miners have limited countermeasures:
Selling BTC to survive: In Q1 2026 alone, listed mining companies reduced holdings by over 32,000 BTC to cover operating costs.
Shutting down machines: High-cost miners are frequently turning rigs on and off based on price swings, raising the sensitivity of mining difficulty to price to 0.62. In the second week of June, network difficulty dropped 10%.
Pivoting to AI: Some mining companies are shifting to AI and HPC facilities, but VanEck estimates a full transformation for publicly listed miners would require an additional $50 billion in capital.
Is This Really Sustainable Long-Term?
In a June 2026 report, Fidelity offered an optimistic view: miners' average daily income has grown from roughly $26,000 during the first halving cycle to about $40.2 million today, as price appreciation offsets block reward declines. They argue that Bitcoin's security does not rely on a single revenue source.
But this conclusion has a premise: it discusses "historical data." When the price remains below production cost for five months and the fee ratio drops below 1%, miners face not "theoretical security" but "who pays next month's bills."
Galaxy's report puts it bluntly: "A dormant mempool will raise serious questions about the long-term sustainability of miner revenue post-halving."
How to Verify the Current State
Open mempool.space or your preferred block explorer and check these three indicators for the Bitcoin network:
Current average fee rate (sats/vbyte) — if below 5, the network is idle
Mempool transaction count — if below 5,000, activity is low
Total fees in the last 24 hours — if below 100 BTC, miner income from the fee market is extremely low
Comparing this data with the period around the 2024 halving will give you a visceral sense of how much the fee market has shrunk.
If you are evaluating mining-related investments or operational decisions, the core near-term variable remains the price of Bitcoin itself, not improvements in the fee market. Protocol upgrades like Pectra primarily affect Ethereum; whether Bitcoin scaling solutions (such as Lightning and BitVM) can bring large-scale on-chain settlement demand remains unknown. Until the fee market recovers, miner survival will be highly dependent on a rebound in Bitcoin's price.
