Electricity is 60-80% of Bitcoin mining operating costs. This guide covers how to calculate cost per BTC mined, what electricity rates make mining profitable, and how to access cheaper power.
No solo miner finds a block every day. Mining pools let you combine your hash power with thousands of other miners to find blocks more frequently — and split the reward proportionally. Choosing the right pool affects your actual income more than most miners realize.
Here are the best Bitcoin mining pools in 2026, ranked by what matters.
How Mining Pools Work
When you mine in a pool:
- You point your ASICs at the pool's stratum server
- You submit "shares" — partial work that proves you're contributing hash power
- When the pool finds a block (receives the 3.125 BTC reward + transaction fees), it distributes the reward proportionally to contributors based on shares
- The pool operator takes a fee (typically 0–2%)
Your daily income is approximately:
Daily BTC = (Your Hashrate ÷ Pool Hashrate) × Daily Block Rewards
Payout Schemes: PPS vs. FPPS vs. PPLNS
The payout scheme determines how you're compensated and who bears variance risk:
| Scheme | Full Name | Who Pays Fees | Variance | Best For |
|---|---|---|---|---|
| PPS | Pay Per Share | Pool | Very low | Stable income |
| FPPS | Full Pay Per Share | Pool | Very low | Stable income + fee income |
| PPLNS | Pay Per Last N Shares | Miner | Higher | Large miners, long-term |
| Solo | Solo mining | Miner | Extreme | Very large operations |
FPPS is generally best for most miners — you get paid for both block subsidies AND transaction fees, even if the pool hasn't found a block recently. The pool assumes the variance risk.
Best Bitcoin Mining Pools 2026
1. Foundry USA Pool
Best for: US-based miners, institutional-scale operations
- Fee: 0% (FPPS)
- Hashrate: ~200–250 EH/s (often #1 or #2 globally)
- Payout scheme: FPPS
- Minimum payout: 0.005 BTC
- HQ: Rochester, NY (DCG subsidiary)
- Notable: Largest or second-largest pool by hashrate; US-based; no fee is a major advantage
Why Foundry: Zero fee on FPPS is remarkable. Most competitors charge 1–2%. On a $10,000/month mining operation, that's $100–$200 saved monthly. Foundry is the dominant US pool with excellent uptime and support for large-scale miners.
2. Antpool
Best for: Bitmain ASIC users, global operations
- Fee: 0% (FPPS) or PPS+ options
- Hashrate: ~150–200 EH/s
- Payout scheme: FPPS, PPS+, PPLNS
- Minimum payout: 0.001 BTC
- HQ: Shenzhen, China (Bitmain subsidiary)
- Notable: One of the oldest and most reliable pools; multiple payout options
Concern: Chinese ownership means geopolitical risk for some miners. Bitmain's centralized influence over the Bitcoin network is an ongoing discussion in the community.
3. ViaBTC
Best for: Flexibility, multiple cryptocurrencies
- Fee: 2% (PPS) or 1% (PPLNS)
- Hashrate: ~60–80 EH/s
- Payout scheme: PPS, PPLNS, SOLO
- Minimum payout: 0.01 BTC
- HQ: China/Global
- Notable: Long-standing pool with solid reputation; also mines BCH, LTC, ETH Classic
4. F2Pool
Best for: Global miners, multi-coin
- Fee: 2.5% (PPS+)
- Hashrate: ~80–100 EH/s
- Payout scheme: PPS+
- Minimum payout: 0.001 BTC
- HQ: Beijing/Global
- Notable: One of the oldest pools (founded 2013); extensive global network
5. Ocean (OCEAN)
Best for: Bitcoin decentralization advocates, transparent block construction
- Fee: 2% (TIDES — transparent payout scheme)
- Hashrate: ~5–15 EH/s (growing)
- Payout scheme: TIDES (Transparent Index of Distinct Extended Shares)
- Minimum payout: Variable
- HQ: Decentralized (backed by Jack Dorsey)
- Notable: Directly pays miners via coinbase transaction — no custodied pool balance; miners can see exactly how their block template is constructed
Why Ocean: Ocean is the most Bitcoin-philosophically aligned pool. Miners are paid directly on-chain (no custodied balance to lose), and the block template construction is transparent. If you care about Bitcoin decentralization, Ocean deserves support even at slightly higher fees.
6. MARA Pool (Marathon)
Best for: Institutional miners aligned with Marathon Digital's approach
- Fee: Varies
- Hashrate: ~30–40 EH/s
- Payout scheme: FPPS
- Notable: Marathon's own pool; publicly traded Bitcoin miner running its own pool
7. SBI Crypto (formerly Slush Pool — Braiins)
Best for: Advanced miners who want open-source firmware
- Fee: 2% (Score-based payout)
- Hashrate: ~5–10 EH/s
- Payout scheme: Unique scoring system
- Notable: World's first Bitcoin mining pool (launched 2010 as Slush Pool); Braiins OS+ firmware integration optimizes ASIC efficiency
Why Braiins: If you run Braiins OS+ firmware on your Bitmain ASICs, connecting to Braiins Pool allows autotuning and efficiency optimization that can increase hash rate 10–20% at same power consumption.
Pool Comparison Table
| Pool | Fee | Scheme | Hashrate | US-based | Best For |
|---|---|---|---|---|---|

| Antpool | 0% | FPPS | ~180 EH/s | No | Global, Bitmain users |
| F2Pool | 2.5% | PPS+ | ~90 EH/s | No | Global multi-coin |
| ViaBTC | 1–2% | PPLNS/PPS | ~70 EH/s | No | Flexibility |
| Ocean | 2% | TIDES | ~10 EH/s | Yes | Decentralization |
| Braiins | 2% | Score | ~8 EH/s | No | Braiins OS+ users |
How to Choose a Mining Pool
1. Fee Structure
For most miners, FPPS with 0% fee (Foundry USA) is optimal. Every percentage point of fee directly reduces your income.
2. Pool Size
Larger pools = more frequent payouts with less variance. Smaller pools = less frequent payouts but same long-term income. For miners with small operations (1–10 ASICs), larger pools provide more consistent cash flow.
3. Geographic Latency
Connect your ASICs to the pool's nearest stratum server. High latency causes stale shares — work submitted after a block is already found — wasting hash power.
4. Decentralization Considerations
Mining pool concentration is a Bitcoin security concern. The top 3–4 pools often control 60–70% of global hash power. Supporting smaller pools like Ocean or Braiins helps distribute hash power and reduces 51% attack risk.
5. Payout Minimums
Small miners (1–3 ASICs) should choose pools with low minimum payouts (0.001–0.005 BTC) to receive regular payments without excessive waiting.
Frequently Asked Questions
Which mining pool pays the most? Long-term, all FPPS pools should pay approximately the same. The difference is fees — Foundry USA at 0% keeps more of your earnings vs. F2Pool at 2.5%.
Is solo mining worth it? At current difficulty, solo mining with consumer hardware (1–100 ASICs) could take years to find a single block. Ocean offers "solo mode" where you can mine solo but use the pool's infrastructure — occasionally hitting the full ~3.125 BTC jackpot.
How many pools should I use? Most miners use one pool. Some split between two for redundancy — if one pool has downtime, you're still mining. With Foundry as primary and Ocean or Braiins as backup, you maintain income while supporting decentralization.
Can I switch pools anytime? Yes. Pool switching is instant — just update the stratum URL in your ASIC's configuration. There's no lock-in or penalty.
Does it matter which pool I choose for profitability? Yes, fees matter. A 2% fee on $10,000/month of mining revenue = $2,400/year. Over a 3-year ASIC lifecycle, choosing a 0% pool over a 2% pool saves $7,200 on that one machine.
