Solo Mining vs Pool Mining in 2026: Which One Is Actually Worth It?

Every time a solo-mining headline lands — like the December 2024 story of a 120 TH/s used rig hitting a full block and 3.125 BTC overnight — a wave of retail miners gets tempted again. “I’m already paying for power, why hand over the pool fee?” Does that argument actually survive 2026 reality? Below we drop the real divisor of 920 EH/s network hashrate into the formula and put solo jackpot probability, pool steady revenue, variance, and psychology on one page, so you can read the ledger before clicking the “solo” button.

What are the actual odds of solo mining

Math first. Bitcoin produces a block about every ten minutes, or roughly 144 per day. Solo jackpot probability = your hashrate / network hashrate.

Plug a flagship rig in:

• An S23 Hydro at 580 TH/s = 580 / (920 × 10^6) ≈ 6.3 × 10^-7 of the network
• Daily jackpot probability = 6.3 × 10^-7 × 144 ≈ 0.0000907
• Expected interval = 1 / 0.0000907 ≈ 11,030 days ≈ 30.2 years

One top ASIC mining solo against Bitcoin waits roughly 30 years on average for a single block. Which is why solo at small scale is mathematically very close to buying a lottery ticket.

Scale to ten S23 Hydros (58 kW industrial power) and the average drops to about 3 years. Even so, the variance remains enormous — you could hit it in six months or wait six years without movement.

The smooth income curve of pool mining

A pool aggregates everyone’s hashrate into one super-miner and distributes rewards proportionally. Individual revenue switches from Poisson to nearly constant, and variance collapses.

The two dominant payout models:

• FPPS (Full Pay Per Share): pays theoretical revenue daily regardless of whether the pool actually found blocks. Fees of 2-4%
• PPLNS (Pay Per Last N Shares): pays based on the pool’s actual blocks hit during the last N shares window. Fees of 0-2%, slightly better long-term but with mild variance

For one-to-ten-rig operations, FPPS is the near-universal default. It bundles variance risk and sells it to the pool, and the miner buys cash flow stability.

A worked example with one S23 Hydro on Foundry USA Pool (FPPS, 2% fee):

• Daily theoretical gross: 19.27 USD
• Pool fee deducted: 0.39 USD
• Daily payout: 18.88 USD

Compared to “30-year expectation” from solo, 18.88 USD a day is real cash.

Both curves on one chart

Modeling 365 days, ten S23 Hydros, 0.09 USD/kWh:

The shape says it all — pool mining traces a smooth, certain positive line, while solo traces a brutally bimodal curve. Long-run expectation converges between them (pool loses 2% to fees), but in any finite window pool wins on stability.

The narrow case where solo makes sense

Solo is not pointless, but the qualifying profile is narrow.

• Hashrate of 1 EH/s or more (about 1,700 S23 Hydros): blocks land roughly every 7 days, variance is compressed by scale
• Very deep cash reserves: can absorb six to twelve months of zero blocks
• Tax angle: certain jurisdictions treat occasional lump-sum mining income more favorably (verify with a tax professional)
• Mental discipline: solo encourages dangerous “we are about to hit it” behavior around hashrate reallocation

For nearly all home and small-farm operators, solo is wrong mathematically, psychologically, and on cash flow. The conclusion matches what we wrote in is home mining still profitable in 2026 — in the small-hashrate era every point of stability is worth more.

Hard rules for picking a pool

Pool choice becomes the next big decision. A few rules that hold up in 2026:

• Prefer FPPS pools above 1 GH/s aggregate: Foundry USA, AntPool, F2Pool still anchor the top tier
• Avoid anything charging more than 4%: fees eat directly into an already thin margin
• Insist on BTC settlement: avoid pools paying out in their own tokens
• Minimum payout under 0.001 BTC: keeps your ability to switch pools or exit fluid
• Check whether MEV revenue is shared: there is real money hidden in pool fee structures

A 2-4% fee looks tiny on paper, but with electricity eating 60%+ of revenue, 2% is actually 10-20% of net margin. Worth one or two days of careful comparison rather than picking based on an ad.

The “semi-solo” middle ground

A handful of pools — OCEAN, SoloMining.com — implement a semi-solo model with PPLNS-flavored distribution but preserved jackpot upside. The math is essentially “lower-efficiency FPPS.” Unless you have a real attachment to the jackpot narrative, the detour adds nothing.

What a realistic home miner should actually do

Compressed into actionable guidance:

• 1 to 3 rigs: 100% pool mining, pick FPPS, focus on electricity
• 4 to 20 rigs: still pool mining, optionally split across 2-3 pools to hedge counterparty risk
• 20+ rigs but under 1 EH/s: pool by default, optionally allocate 5% hashrate to a solo experiment
• 1 EH/s and above: hybrid strategy, engage a professional hashrate scheduler

The tiering matches what we laid out in choosing a Bitcoin mining pool. The biggest miscalculation home miners make in 2026 is not which pool — it is underestimating how much variance damages small operators. Solo is a toy for the wealthy and the narrative-driven; pools are a tool for operators. Read the ledger before you decide which one you want to be.
