Bitcoin mining fees will be close to zero as mining costs will approach $80,000 and difficulty will drop by 5%.
Bitcoin mining still operates on subsidies, not demand.
As we head into the next Bitcoin difficulty adjustment window, which CoinWarz currently estimates to be April 18, 2026, this is a more useful place to start. Difficulty is expected to decrease by 4.91% from 138.97 trillion to 132.14 trillion.
The schedule is less important than the structure beneath it. YCharts, using Blockchain.com data, found that daily Bitcoin transaction fees on April 8 were 2,443 BTC, down 69% year-over-year.
With the block subsidy pegged at 3.125 BTC and the network producing around 144 blocks per day, fees still only contribute a portion of miners’ revenue in BTC.
The next few weeks will then consist of narrower, more useful questions. If fees are fixed near the bottom, what actually determines a miner’s viability?
The answer starts with the revenue stack, moves to the cost stack, and then to the adaptation stack. Revenues are still overwhelmingly dependent on subsidies and the price of Bitcoin.
Costs still depend on power, vehicle efficiency, debt and financial policies. Adaptation will depend on how much flexibility operators have when mining alone no longer provides sufficient returns for power and infrastructure.
The role of upcoming difficulties is secondary. A lower difficulty target can improve production per hash unit when prices and fees remain stable, thus easing the burden on operators. In the current environment, these distinctions form the overall operational map of miners.
Subsidies carry the revenue stack and fees are kept close to the lowest level.
Bitcoin miners receive money from two sources: subsidies and fees. Subsidies are protocol-level issuances attached to each block. A fee is an additional amount paid by the user to confirm the transaction.
In a more robust on-chain environment, the fee tier becomes a true contributor to the miner economy. At weaker ones, they become less relevant, leaving miners much more directly tied to the market price of Bitcoin.
Here is the current situation. A recent snapshot of mempool.space shows low, medium, and high priority transactions clustered at approximately 1 sat/vB. YCharts recorded the average Bitcoin transaction fee on April 8 at $0.3335, down 80.53% from a year ago. The network is still operating smoothly, blocks are still being mined, and users still have affordable access to block space.
The revenue impact for miners is simple. Fee income provides little incremental support. Bitcoin price was around $71,800 on April 10, up 7.4% over the past 7 days and 3.1% over the past 30 days. This move is primarily aided by the value of subsidies rather than a revival of user-paid demand for block space.
The scale of the imbalance is large enough to define a frame in itself. Bitcoin still produces about 144 blocks per day. At 3.125 BTC per block, this means approximately 450 BTC in new daily subsidy before fees. Based on this, looking at the April 8 total fee figure of 2.443 BTC, we see that fees account for about 1% and half of miners’ revenue in BTC.
This is why live questions keep miners alive when fee tiers are of little help. The next reset, even if it belongs in the correct location, still belongs to the analysis.
Setting the difficulty lower can improve economics at the vehicle level because it reduces the computational work miners need to find blocks. It can relieve pressure. Miner viability in the coming weeks will still largely be determined by price, efficiency, power costs, debt and financial discipline. Power costs, machine quality, debt burden and financial policies will determine who bends first.
Separating the revenue side into subsidies and prices makes it much easier to see the cost stack. The viability of miners depends on who can produce Bitcoin at a cost that leaves room for operating cash flow.
This will depend on electricity prices, the efficiency of the vehicles, hosting costs, the level of debt on the balance sheet and whether management has sufficient financial flexibility to avoid selling in weak circumstances.
CoinShares provides the clearest external framework for that hierarchy. In its Q1 2026 mining report, CoinShares stated that Q4 2025 was the toughest quarter for miners since the halving in 2024, with the weighted average public miner cash production cost in Q4 2025 being close to $79,995 per BTC.
These figures clearly show how narrow the spread has become across the listed space. CoinShares also stated that miners below S19 XP who pay more than 6 cents per kilowatt-hour are losing $30 per PH/day.
This helps build a much clearer three-tier hierarchy.
The first tier consists of low-cost operators with modern fleets, favorable hosting or self-mining capabilities, and balance sheets that can absorb volatility without an immediate forced sale.
These miners are still under pressure from the low fee market, but they have enough efficiency and financial flexibility to overcome this. Their problem is not immediate viability but margin compression.
The second tier is the disciplined middle tier. These operators can survive only through tighter financial management, more selective deployment, slower expansion, and stricter capital expenditure filters.
If the Bitcoin price holds and the anticipated difficulties fall close to current expectations, it could survive the coming weeks. Because the fee tier offers very little support, there is still much less room for error than the top tier.
The third layer is where the real burden lies. This includes operators with expensive legacy vehicles, running older machines, miners with weak power economics, and companies with capital structures that don’t give much time.
This group is disrupted first because weak fees eliminate one revenue line that could dampen a difficult quarter. For them, the issue is no longer about growth. This concerns curtailment, site-specific triage, machine outages, opportunistic finance sales and whether parts of the fleet are still eligible for incremental capital.
This is the point of operating leverage where the scope of mining often becomes ambiguous. It is mainly used as an input to the hash price and cash margin, but the price is still important. CoinShares estimates that if Bitcoin recovers to $100,000, the hash price could rise to around $37 per PH/day, and if it retests $126,000, it could rise to around $59 per PH/day.
These ranges show how quickly things can improve when the price moves far enough. It also shows why the current environment still feels tight. Bitcoin has stabilized, but remains well below levels that provide wider comfort across the mining stack.
This has made fiscal policy a more important variable than usual. Operators holding stronger Treasury bonds can hold them even during periods when fees are weak and hash prices are moderate.
Less flexible operators will have to decide more quickly whether to sell BTC, cut capital spending, idle old equipment, or withdraw from marginal sites. In markets where subsidies do almost all the work, money management becomes part of the production model.
Collapse, vehicle classification, and AI pivot define the adaptive stack for the next reset period.
As revenues continue to shrink and cost stacks tighten, the next question is adaptation. What do miners actually do once pure Bitcoin mining stops providing sufficient operating leverage?
The first adaptation is reduction. Operators block high-cost machines, reduce exposure to vulnerable sites and preserve cash while waiting for better pricing terms or a more favorable difficulty profile.
The second is fleet classification. Capital is directed to the most efficient hardware and highest-performing sites, while older systems stay online only if they can afford the power and hosting costs.
The third is strategic diversification. Miners are starting to look beyond Bitcoin mining itself and ask what their power, land, cooling and data center assets can get in adjacent markets.
CoinShares said in a report that listed miners have announced more than $70 billion in cumulative AI and HPC contracts and could capture up to 70% of AI revenue by the end of the year. This is an increase from the current figure of around 30%.
This prediction tells us a lot about how miners rank options. Sites with sufficient power access and data center potential can make more money from other workloads than mining Bitcoin in a cheap environment.
Low fees also make mining less attractive compared to other compute-intensive companies competing for the same infrastructure space. Miners don’t need ideological convictions to make that transition.
The next reset period still presents a clear short-term test for the market. CoinWarz announces the next difficulty adjustment on April 18th, lowering the expected move to 132.14 trillion. If that adjustment approaches expectations, miners should see some margin relief on production economics. The more pointed question comes next. Is anything actually changing in the fee layer?
Any meaningful improvement will require firmness in the Bitcoin price, a noticeable fee rebound, or both. Without fee recovery, the low difficulty setting leaves miners still dependent on subsidies and prices.
In the coming weeks, the winners will likely be miners with efficient vehicles, better power economics, stronger financial management, and enough strategic flexibility to move capacity to where returns are highest.
The losers are likely to be miners who need fee support to compensate for legacy equipment, high power costs, or weak balance sheets.
Bitcoin mining is still producing blocks as scheduled, and the next difficulty adjustment will bring some relief to operators.
The deeper conditions remain the same. Demand for block space contributes little, and the viability of miners will depend on whether they can tolerate a weak fee environment long enough for prices, fees, or both to improve.
