1. Understanding Solo Mining: Going It Alone

Solo mining represents the original Bitcoin mining approach where an individual miner operates independently, attempting to solve blocks entirely on their own without sharing hashrate or rewards with any other miners. When successful, solo miners receive the complete block reward of 3.125 BTC (post-2024 halving) plus all transaction fees, currently totaling approximately $275,000-$290,000 per block at May 2026 Bitcoin prices around $87,500. This represents the maximum possible payout from mining a single block and creates tremendous appeal for miners dreaming of life-changing jackpot-style rewards.

How Solo Mining Works

In solo mining, you run a full Bitcoin node that maintains a complete copy of the blockchain and validates all transactions independently. Your mining hardware connects directly to your node rather than a pool server, receiving block templates containing candidate transactions to include in the next block. Your ASICs perform trillions of hashing calculations per second, searching for a nonce value that produces a block hash below the current difficulty target. When you find a valid solution, your node broadcasts the block to the network, and if accepted, you receive the entire block reward directly to your configured wallet address.

The technical requirements for solo mining exceed those of pool mining because you must maintain reliable node infrastructure 24/7. This includes sufficient storage for the full blockchain (currently 600+ GB and growing), stable internet connectivity to propagate blocks quickly and minimize orphan risk, and technical knowledge to configure and monitor node operation. Any downtime means missed opportunities to find blocks, and unlike pool mining where short outages only reduce proportional rewards slightly, solo mining downtime represents complete loss of potential during offline periods.

The Economics of Solo Mining

Solo mining operates on an all-or-nothing economic model. You either find a block and receive the full $275,000+ reward, or you receive absolutely nothing despite potentially months or years of continuous operation and electricity costs. Your expected value over long timeframes equals what you would earn in a pool (minus pool fees), but the variance is extreme. A miner with 200 TH/s represents only 0.00002% of the current ~1 ZH/s network hashrate, giving them approximately 1 in 5 million chance of finding any given block.

This astronomical variance means solo miners with typical hashrates of 100-1,000 TH/s might realistically expect to find a block every 2-15 years on average. During the wait, they accumulate zero revenue while paying continuous electricity costs that could total $10,000-$100,000+ depending on operation scale and duration. When they finally find a block, the $275,000 reward must compensate for all accumulated costs plus provide profit, which works mathematically over infinite timeframes but creates severe cash flow challenges for real-world operations with finite capital and patience.

Recent Solo Mining Successes

Despite astronomical odds, some solo miners achieve remarkable success. In early 2026, individual miners successfully validated complete blocks worth $200,000-$300,000 each on multiple occasions. These wins generate significant publicity and excitement in the mining community, reinforcing the lottery-ticket appeal of solo mining. However, the statistics reveal the harsh reality: of the approximately 52,000 blocks mined annually, only 22 were found by solo miners in the previous year, representing just 0.04% of total production. This means 99.96% of all blocks go to mining pools, demonstrating overwhelming pool dominance in actual mining outcomes.

The successful solo miners typically represent either extremely small operations getting extraordinarily lucky (mining with single ASICs for months before hitting a block), or large operations with significant hashrate that still face long variance but have sufficient scale to justify solo mining’s economics. The publicity surrounding solo wins creates survivorship bias—we hear about the lucky few who win but not the thousands who mine for months or years with zero returns despite substantial investments in equipment and electricity.

Who Should Consider Solo Mining

Solo mining makes economic sense only for specific miner profiles. Large operations with 10+ PH/s (10,000+ TH/s) achieve block discovery frequencies measured in weeks or months rather than years, making variance more manageable while retaining upside from occasional block wins. These operators have sufficient scale that the 1-3% pool fee savings amount to meaningful absolute value ($100,000+ annually), potentially justifying solo mining’s administrative overhead and variance exposure.

Hobbyist miners with single ASICs sometimes solo mine as a lottery-ticket speculation, understanding that expected value is negative once electricity costs are considered but enjoying the remote possibility of a $275,000 windfall. This approach treats mining as entertainment or speculation rather than business, which can be rational if you’re mining equipment you already own and view electricity costs as acceptable for the entertainment value and remote jackpot possibility.

The vast middle ground of small-to-medium operations with 100 TH/s to 5 PH/s finds solo mining economically irrational in nearly all cases. The variance is too extreme to generate reliable cash flow, the probability of ever finding a block before equipment becomes obsolete is uncomfortably low, and the pool fee savings don’t offset the operational challenges and revenue uncertainty that solo mining creates compared to stable pool mining income.

2. Pool Mining Explained: Strength in Numbers

Pool mining represents the collaborative approach where thousands of individual miners combine their hashrate into a single coordinated effort, dramatically increasing block discovery frequency while sharing rewards proportionally based on contributed work. Instead of each miner attempting to find blocks independently with low individual probability, the pool’s aggregate hashrate finds blocks regularly (sometimes multiple times per hour for large pools), then distributes rewards to participants according to their percentage of total pool hashrate minus small administrative fees.

How Mining Pools Function

When you join a mining pool, your ASICs connect to the pool’s servers rather than running a full Bitcoin node yourself. The pool operates the full node infrastructure, constructs block templates, and coordinates work distribution among all connected miners. Your equipment receives smaller work units called “shares” that represent portions of the full difficulty target. Each time your miner finds a valid share (which happens hundreds or thousands of times daily), you submit it to the pool as proof of your ongoing contribution to the collective hashrate.

The pool tracks all shares submitted by all miners continuously. When the pool finds a valid block (which happens when one miner’s share happens to meet the full network difficulty, not just the lower pool share difficulty), the pool receives the block reward and transaction fees. The pool then distributes this reward among all contributing miners based on their share of total submitted work during the relevant time window, minus the pool’s operational fee typically ranging from 1-3%.

Pool Payout Methods Explained

Mining pools use several different payout schemes that affect reward distribution, variance, and strategic considerations. Understanding these methods is crucial for selecting appropriate pools and optimizing mining profitability:

PPS (Pay Per Share)

PPS pools pay a fixed rate for every valid share you submit, regardless of whether the pool finds blocks. The pool assumes all variance risk, guaranteeing you a predictable payout based solely on your contributed hashrate. If the pool experiences bad luck and finds fewer blocks than expected, the pool operator absorbs the loss. Conversely, if the pool gets lucky, the operator keeps the excess. PPS offers maximum stability and predictability, making it ideal for miners who prioritize steady cash flow over variance optimization. However, PPS fees tend to be highest (2.5-3%) because pools must charge more to compensate for variance risk they assume.

FPPS (Full Pay Per Share)

FPPS expands on PPS by including transaction fees in the guaranteed payout calculation. Where traditional PPS only guarantees payment based on the block subsidy (3.125 BTC), FPPS calculates expected transaction fees over recent periods and includes them in your per-share payment. This typically increases payouts by 5-20% compared to basic PPS depending on network congestion and transaction fee levels. FPPS maintains PPS’s predictability advantage while capturing more of the total block value, making it one of the most popular payout schemes for miners prioritizing stability.

PPLNS (Pay Per Last N Shares)

PPLNS pays only when the pool finds blocks, distributing rewards based on shares submitted during a recent window (the “N” value) before block discovery. If you contributed 1% of pool shares during the relevant window, you receive 1% of the block reward minus pool fees. PPLNS introduces variance—payouts fluctuate based on pool luck in finding blocks. During lucky periods with many blocks found, PPLNS pays more than PPS. During unlucky stretches, it pays less or nothing. PPLNS fees are typically lower (1-2%) than PPS because pools don’t assume variance risk. This method suits miners comfortable with variance who want to maximize expected value over long timeframes.

PPS+ (Pay Per Share Plus)

PPS+ combines elements of PPS and PPLNS, paying a fixed rate for the block subsidy portion (like PPS) while distributing transaction fees using PPLNS methodology. This hybrid approach provides baseline stability from the guaranteed subsidy payment while allowing miners to benefit from transaction fee variance. When network fees spike during congestion periods, PPS+ miners capture upside. During quiet periods with low fees, they receive guaranteed subsidy payments that prevent downside. PPS+ represents a middle ground between maximum stability (FPPS) and maximum expected value (PPLNS).

Major Mining Pools in 2026

The Bitcoin mining pool landscape in 2026 is dominated by several large operators controlling significant portions of network hashrate:

Larger pools find blocks more frequently, providing smoother, more predictable payouts with less variance. Smaller pools experience higher variance with longer gaps between blocks but may offer lower fees or other advantages. The largest pools also tend to have better infrastructure, lower orphan rates, and more sophisticated payout options, though centralization concerns arise when any single pool controls more than 25-30% of network hashrate.

Pool Selection Considerations

Choosing the right pool involves balancing multiple factors beyond just fees. Payout frequency matters—larger pools pay more often with lower per-payout variance. Geographic location affects latency and orphan risk, with pools closer to your physical location potentially offering slight efficiency advantages. Payout methods determine variance and expected value as discussed above. Minimum payout thresholds affect how quickly you can access your earnings, with lower minimums providing better liquidity but potentially higher transaction costs from more frequent payouts.

Pool reputation and stability are critical—you’re trusting the pool to honestly track your shares and pay appropriately. Established pools with multi-year track records and transparent operations reduce counterparty risk. Some pools offer merged mining that simultaneously mines multiple cryptocurrencies (Bitcoin plus Namecoin, Elastos, etc.), slightly increasing total revenue. Dashboard features, mobile apps, and notification systems vary by pool, with better tools helping you monitor performance and respond quickly to issues.

3. Probability and Mathematics: Your Chances of Success

Understanding the mathematical probability of finding blocks as a solo miner is essential for making rational decisions about mining strategies. The numbers are sobering and reveal why pool mining dominates the industry despite solo mining’s theoretical appeal.

Basic Probability Formula

Your probability of finding any specific block as a solo miner depends on your hashrate as a percentage of total network hashrate:

With current May 2026 network conditions showing approximately 950-1,000 EH/s (exahashes per second) total network hashrate, we can calculate probabilities for various miner scales:

These calculations demonstrate why solo mining is fundamentally impractical for typical miners. A single 200 TH/s ASIC would expect to wait 91 years between blocks on average—far longer than the equipment’s useful life. Even a respectable 20 PH/s operation faces 11-month waits between blocks, creating severe cash flow challenges and risk that equipment becomes obsolete before finding a single block.

Variance and Probability Distribution

The “expected time” calculations above represent averages, but actual outcomes follow a probability distribution with extreme variance. The probability of finding your first block follows an exponential distribution, meaning:

• You have approximately 63% chance of finding a block within the expected time period
• 37% chance it takes longer than expected
• 18% chance it takes twice as long as expected
• 5% chance it takes three times as long
• Small but real chance it takes 5-10x longer or never happens before equipment obsolescence

This variance cuts both ways—you might also get lucky and find a block much sooner than expected. The two solo miners who found blocks in early 2026 likely experienced this positive variance. However, for every lucky miner who finds a block in days or weeks, many others mine for years without success despite similar hashrate. The mathematics ensure that outcomes average correctly over large numbers of trials, but individual miners face lottery-like uncertainty.

Pool Mining Probability and Variance

Pool mining fundamentally transforms these probability dynamics. Instead of your individual hashrate competing against the entire network, you share in the pool’s much larger collective hashrate. A pool with 100 PH/s (about 10% of network hashrate) finds approximately 14.4 blocks per day on average—one block every 100 minutes.

Your individual payout from each block is much smaller (proportional to your percentage of pool hashrate), but the frequency is dramatically higher. A 200 TH/s miner in a 100 PH/s pool represents 0.0002% of pool hashrate and receives 0.0002% of each block reward. Instead of waiting 91 years for a full $275,000 block, you receive approximately $550 per block (0.0002% × $275,000), but you receive this payout 14.4 times per day rather than once per 91 years.

This calculation shows pool mining delivers the same expected value (actually slightly less due to fees) but with dramatically lower variance transformed from one large payout every 91 years to hundreds of small payouts daily.

Statistical Significance and Time Horizons

For solo mining expected value to materialize requires time horizons that exceed equipment lifespans and business planning horizons. A miner with 2 PH/s facing 9-year average block discovery times cannot realistically solo mine because:

• Equipment becomes obsolete in 2-4 years as more efficient ASICs enter the market
• Network difficulty continuously increases, stretching expected block times even longer
• 9-year timelines exceed most investors’ patience and capital availability
• Extreme variance means high probability of zero returns despite years of operation
• Continuous electricity costs accumulate to hundreds of thousands of dollars before potential payout

Pool mining allows expected value to materialize over days and weeks rather than years and decades, aligning mathematical expectations with practical business operations and cash flow requirements.

4. Profitability Comparison: Expected Returns and Variance

While probability mathematics reveal dramatic differences in payout frequency and variance between solo and pool mining, profitability analysis examines the actual financial outcomes these strategies produce. Understanding expected returns, variance impact on cash flow, and total cost of ownership determines which approach makes economic sense for different miner profiles.

Expected Value Comparison

From a pure expected value perspective over infinite timeframes, solo mining and pool mining produce nearly identical returns. Both approaches earn you a proportional share of network block rewards based on your contributed hashrate. Solo mining captures 100% of occasional blocks while pool mining captures a small percentage of frequent blocks, but the mathematics average to the same result minus pool fees.

This example reveals a critical insight: pool mining often delivers higher practical returns than solo mining’s theoretical expected value because pools capture transaction fees in their payout calculations while solo miners’ low block probability means transaction fee expected value is nearly zero in practical timeframes. Additionally, pool mining’s predictable cash flow allows reinvestment and operational optimization that lumpy solo payouts cannot match.

Electricity Cost Impact

Electricity costs create a fundamental asymmetry between solo and pool mining profitability. Pool miners receive steady revenue that consistently exceeds electricity costs (assuming profitable equipment and rates), generating positive cash flow from day one. Solo miners pay continuous electricity costs while potentially receiving zero revenue for months or years, creating severe negative cash flow that consumes capital until a block is found.

This analysis shows that while solo mining eventually delivers positive returns if you mine long enough to find a block, the capital tied up in accumulated electricity costs and the time value of money make pool mining dramatically superior in practical terms. The $167,000 in electricity costs spent over 91 years waiting for a solo block could generate $256,000 in profits through pool mining over the same period, even after paying pool fees.

Variance Impact on Profitability

Variance affects profitability beyond simple expected value calculations through several mechanisms. High variance creates cash flow volatility that prevents smooth business operations, forces miners to maintain large capital reserves for periods of zero revenue, and introduces risk of business failure before positive outcomes materialize. Low variance allows tight operational budgeting, predictable reinvestment schedules, and stable financial planning.

Solo mining’s extreme variance means you either vastly outperform expectations (finding a block in weeks rather than years) or vastly underperform (mining for years without success). This creates a lottery-like outcome distribution where most participants lose money while a lucky few make substantial profits. The average is positive, but median outcome is likely zero revenue despite substantial costs, making solo mining a negative expected value proposition for most practical scenarios when time-value-of-money and business operational constraints are considered.

Pool mining’s low variance produces outcomes clustered tightly around expected values. Your daily, weekly, and monthly revenues vary by only 5-10% from predictions, allowing accurate financial forecasting and efficient capital allocation. This predictability has economic value beyond raw expected value—businesses pay for certainty and stability because it enables better decision-making and resource optimization.

Profitability Over Different Hashrate Scales

The solo versus pool profitability comparison shifts at different hashrate scales, with solo mining becoming more viable (though still inferior for most) as hashrate increases:

This analysis demonstrates that pool mining maintains profitability advantage across all practical hashrate scales due to transaction fee capture, lower variance, and eliminated capital costs from waiting for blocks. Even at 2 EH/s (2,000 PH/s) representing $100M+ in equipment investment and operating at massive industrial scale, pool mining delivers 41% higher revenue than solo expected value primarily due to consistent transaction fee capture versus solo’s lottery-like block probability.

5. Risk Analysis: Variance, Stability, and Strategic Considerations

Beyond expected profitability, risk assessment critically impacts the solo versus pool mining decision. The two approaches present dramatically different risk profiles across financial, operational, and strategic dimensions that affect mining viability and business sustainability.

Variance Risk and Cash Flow

Solo mining’s extreme variance creates existential business risk through unpredictable cash flows. A mining operation spending $5,000 monthly on electricity while generating zero revenue cannot sustain operations indefinitely regardless of theoretical positive expected value. Most miners have finite capital reserves that deplete during extended periods without block discoveries, forcing shutdown before expected returns materialize.

This variance risk scales with operation size but never fully disappears. A 20 PH/s operation expecting blocks every 11 months faces 37% probability that first block takes 22+ months, requiring $110,000+ in accumulated electricity costs before any revenue. Many mining operations cannot absorb this level of capital consumption while waiting for uncertain rewards, making solo mining financially impractical despite positive theoretical expected value.

Pool mining eliminates variance risk almost entirely. Daily payouts provide steady cash flow that reliably exceeds operational costs (assuming profitable equipment and electricity rates), allowing miners to pay bills, reinvest in expansion, and operate indefinitely without requiring large capital reserves for revenue uncertainty. This stability enables business planning, loans/financing for expansion, and professional operations that solo mining’s unpredictability prevents.

Technical and Operational Risks

Solo mining requires operating full Bitcoin node infrastructure with 100% uptime for optimal results. Any downtime represents complete lost opportunity—you cannot partially find blocks. If your node is offline for 10% of the time, you lose 10% of your already-tiny block discovery probability with no compensation. Pool mining distributes this risk—short outages simply reduce your proportional share slightly while the pool continues finding blocks and you resume earning immediately when back online.

Node operation introduces technical challenges including blockchain sync maintenance, network connectivity management, block propagation optimization to minimize orphan risk, and sophisticated monitoring to detect issues quickly. These requirements exceed the technical capabilities or interest of many miners who prefer focusing on hardware operation rather than node administration. Pools handle all node infrastructure professionally, allowing miners to focus purely on keeping ASICs running efficiently.

Market and Difficulty Risk

Both solo and pool mining face identical exposure to Bitcoin price volatility and network difficulty increases that affect profitability. However, these risks manifest differently under the two strategies. Pool miners see immediate impact through reduced daily payouts when difficulty rises or prices fall, allowing quick response through operational adjustments, equipment shutdown, or strategy changes.

Solo miners may not receive market signals for months or years if they haven’t found blocks. You could mine through periods of rising difficulty and falling prices, accumulating electricity costs while your probability of ever finding a profitable block diminishes, without receiving any feedback that your operation has become unprofitable. By the time you find a block (if ever), market conditions may have shifted such that the reward doesn’t compensate for accumulated costs.

Pool mining’s frequent payouts provide continuous market feedback, enabling dynamic responses to changing profitability conditions. You can shut down during unprofitable periods, restart when conditions improve, or adjust strategies based on real-time data rather than operating blindly hoping for eventual block discovery under potentially deteriorating economics.

Opportunity Cost and Capital Efficiency

Solo mining ties up capital in both equipment and accumulated electricity costs while generating zero short-term returns. A miner spending $150/month on electricity for a 200 TH/s operation accumulates $1,800 annually in costs while likely receiving $0 in revenue. That $1,800 could generate returns through alternative investments, or the equipment could mine in a pool generating $4,000+ annually in actual revenue rather than theoretical future value.

The opportunity cost of solo mining compounds over time. Every month spent solo mining with zero revenue represents missed pool mining income that could have funded equipment expansion, reduced debt, or provided operating cash flow. If you solo mine for 5 years before finding your first block, you’ve foregone $20,000+ in pool mining profits that could have grown through reinvestment, compounding the true cost of solo mining’s variance beyond just the direct financial outcomes.

Psychological and Behavioral Risks

Solo mining creates psychological challenges that affect decision quality and operational discipline. Extended periods of zero revenue despite continuous costs test patience and conviction, potentially causing premature abandonment before expected returns materialize. The temptation to switch to pool mining “just to see some revenue” can strike after months of zero payouts, causing miners to give up on solo strategies right before variance swings positive.

Conversely, solo mining’s lottery-like appeal encourages irrational persistence. Miners may continue solo operations long after rational analysis suggests shutdown, hoping for the life-changing block reward despite accumulating losses. This gambler’s mentality causes suboptimal decisions where miners would profit more by admitting solo mining isn’t working and switching to predictable pool income.

Pool mining’s steady payouts provide psychological stability and positive reinforcement that supports long-term operational discipline. Seeing daily progress and regular revenue maintains motivation and confirms your mining operation is functioning properly, enabling clear-headed strategic decisions based on data rather than hope or desperation.

Centralization and Philosophical Considerations

Some miners choose solo mining for philosophical reasons related to Bitcoin decentralization, despite inferior economics. Large mining pools controlling 20-30% of network hashrate create centralization concerns where a few operators influence significant portions of Bitcoin’s consensus mechanism. Solo mining distributes block discovery across independent miners, theoretically supporting decentralization values.

However, this philosophical justification faces practical limitations. Solo mining is only viable at large scales (multi-PH/s), meaning most miners must choose pools regardless of preferences. The miners with sufficient scale to solo mine profitably typically represent large corporate operations whose size creates comparable centralization regardless of pool participation. True decentralization requires many small miners, which economically necessitates pool mining for revenue viability.

Additionally, solo mining’s technical requirements (full node operation, block propagation optimization) exceed most miners’ capabilities, leading to reliance on third-party solo mining pools that provide solo mining economics with pool infrastructure. These services reintroduce the same trust and centralization issues as regular pools while sacrificing pool mining’s variance reduction benefits, making them arguably worst of both approaches for most miners.

Final Recommendations

Recommended Pool Selection Criteria

Once you’ve decided on pool mining (the rational choice for most miners), selecting the right pool optimizes your returns and operational experience:

1. Fee structure: Compare total fees including payout methods. FPPS at 2.5% may deliver better net returns than PPLNS at 1.5% due to guaranteed transaction fee inclusion.
2. Pool size: Larger pools (10%+ network hashrate) provide smoother daily payouts. Smaller pools offer higher variance but potentially lower fees and better decentralization.
3. Payout threshold: Lower minimums (0.001 BTC) provide better liquidity than high thresholds (0.01 BTC), especially for smaller operations.
4. Geographic location: Pools with servers near your physical location reduce latency and potential orphan rates, though this effect is minimal (0.1-0.3% impact).
5. Reputation and history: Established pools with 3+ year track records reduce counterparty risk. Check community forums for payout reliability reports.
6. Dashboard and tools: Quality monitoring, mobile apps, and alert systems help optimize operations and respond quickly to issues.
7. Additional features: Merged mining (Namecoin, Elastos), multiple payout options, and flexible withdrawal schedules add value.

Top Pool Recommendations for 2026

Hybrid Strategy: Pool Mining with Occasional Solo Lottery Tickets

Some miners employ a hybrid approach: dedicate 90-95% of hashrate to pool mining for stable income, while pointing 5-10% at solo mining as a “lottery ticket” speculation. This strategy provides:

• Stable cash flow from pool mining to cover all operational costs
• Small possibility of solo block jackpot for entertainment value
• Diversification across both strategies
• Minimal financial risk since pool revenue exceeds total costs

While this approach has emotional appeal, it’s mathematically suboptimal—the 5-10% solo hashrate has negative expected value after fees compared to simply pooling 100% and buying lottery tickets separately. However, for miners who cannot resist solo mining’s appeal but recognize pool mining’s practical superiority, this compromise may offer acceptable balance between rationality and entertainment.

The Bottom Line

The mathematical, financial, and operational analysis is conclusive and overwhelming: pool mining is superior to solo mining for essentially all miners operating at practical scales in 2026. Solo mining offers marginally higher theoretical expected value (1-3% fee savings) but delivers catastrophically worse practical outcomes through extreme variance, zero cash flow for extended periods, inability to capture transaction fees in reasonable timeframes, and operational complexity that most miners cannot efficiently manage.

Pool mining transforms Bitcoin mining from an impractical lottery into a viable business by converting decade-scale expected block discovery times into daily payouts, replacing all-or-nothing variance with predictable income, and eliminating full node operational requirements while capturing transaction fees that solo miners statistically never collect. The 1-3% pool fee is an exceptional value for these transformative benefits, which is why 99.96% of all Bitcoin blocks are found by pools despite solo mining’s theoretical fee-free appeal.

For the tiny minority of miners operating at 100+ PH/s scale with multi-million dollar operations and sufficient capital reserves to sustain extended periods of negative cash flow, solo mining becomes theoretically viable but still typically underperforms pool mining in practice. Even at this scale, the operational complexity, variance management challenges, and missed transaction fee revenue make pool mining the rational default choice unless you have specific philosophical objections to pool participation or unique circumstances that make variance preferable to stability.

The only legitimate use case for solo mining at typical scales is pure speculation or entertainment where you explicitly treat it as gambling rather than mining business. If you enjoy the lottery-ticket aspect and can afford the negative expected value after electricity costs, solo mining may provide entertainment value similar to casino gambling. However, direct lottery tickets or Bitcoin price speculation likely offer better risk/reward profiles for this use case than solo mining’s costly combination of continuous electricity expenses plus infinitesimal win probability.
