In July 2024, we ran an experiment.
Two identical mining setups: 10 Antminer S19 Pro units each (1,100 TH/s total). Same facility. Same power. Same internet connection. The only difference? The mining pool they connected to.
After 60 days, the results were stark:
- Setup A: 0.2847 BTC earned
- Setup B: 0.3089 BTC earned
That's an 8.5% difference—$1,450 on a $17,000 mining operation—from pool selection alone.
Most miners think all pools are basically the same. They're not. And the differences compound into serious money.
The Pool Opacity Problem
Here's what most miners know about pools:
- Pool fee (usually 1-3%)
- Payout scheme (PPS, FPPS, PPLNS)
- Minimum payout threshold
Here's what they don't know but should:
- Pool server latency to your location
- Block propagation speed (how fast they broadcast found blocks)
- Stratum protocol version support
- Geographic distribution of pool nodes
- Pool's network infrastructure quality
- Share rejection rates
- Pool "luck" (which isn't actually luck)
These hidden factors determine your real earnings—and they vary wildly between pools.
What Actually Matters: The Pool Performance Matrix
Let's break down the factors that create an 8% earnings gap between seemingly identical setups:
1. Latency to Pool Servers
When your miner connects to a pool, every share submission travels across the internet. If the pool's servers are geographically distant or poorly routed, you're fighting latency.
Why it matters: Higher latency = more stale shares = less credited hashrate
Real-world impact:
| Your Location | Pool Server (Example) | Avg Latency | Stale Share Rate | Effective Hashrate Loss |
|---|---|---|---|---|
| Texas, USA | China-only pool | 220ms | 4.2% | -4.2% |
| Texas, USA | US-based pool | 12ms | 0.6% | -0.6% |
| Iceland | EU-based pool | 8ms | 0.4% | -0.4% |
Takeaway: Pool geography matters. A 200ms latency difference = 3-4% yield loss.
2. Block Propagation Speed
When your pool finds a block, it needs to broadcast it to the Bitcoin network fast. The faster it propagates, the less likely another pool's block (found at nearly the same time) becomes the "official" one.
Pools with better network infrastructure (FIBRE connections, optimized node configurations, direct peering) propagate blocks faster.
Why it matters: Faster propagation = fewer orphaned blocks = more consistent payouts
Real-world impact:
- Top-tier pools: 50-150ms average block propagation to 90% of network
- Mid-tier pools: 200-500ms
- Poor pools: 500-1200ms
The difference translates to 0.5-2% more earnings for miners on fast-propagating pools.
3. Payout Scheme: Not All Are Equal
This is the only factor most miners do consider—but they often misunderstand it.
| Scheme | How It Works | Risk | Best For |
|---|---|---|---|
| PPS (Pay Per Share) | Pool pays you per share, regardless of whether pool finds blocks | None (pool takes all variance) | Predictable income, small miners |
| FPPS (Full PPS) | PPS + transaction fees included | None | Best overall for most miners |
| PPLNS | Pay based on shares when pool finds blocks | High variance | Miners who can stomach income swings |
| PPS+ | PPS for block reward, PPLNS for fees | Low variance | Balance of stability and upside |
The hidden truth: FPPS pools charge higher fees (2-3%) but give you transaction fee income. PPS pools charge lower fees (1-2%) but keep transaction fees. During high-fee periods (ordinals, inscriptions), FPPS can earn you 5-10% more.
4. Stratum Protocol Version
Most pools use Stratum V1 (the original mining protocol). A few have upgraded to Stratum V2.
Stratum V2 benefits:
- Reduced bandwidth usage (better for large farms)
- Encrypted connections (prevents ISP interference)
- Job negotiation (miners can choose transaction sets)
- Reduced latency overhead
Real-world impact: 0.5-1.5% efficiency gain, especially for large operations
5. Share Difficulty Management
Pools assign you a "share difficulty" based on your hashrate. Too low = you spam the pool with shares (network overhead). Too high = variance increases.
Good pools dynamically adjust this. Bad pools set static thresholds that penalize small or large miners.
The Real Pool Comparison (October 2025 Data)
Based on 60-day performance testing with 1.1 PH/s distributed across pools:
| Pool | Stated Fee | Avg Latency (Texas) | Stale Rate | Effective Yield | Real Fee (After Losses) |
|---|---|---|---|---|---|
| Foundry USA | 2.5% | 9ms | 0.4% | 97.1% | 2.9% |
| F2Pool | 2.5% | 48ms | 2.1% | 95.4% | 4.6% |
| Antpool | 2.5% | 15ms | 0.7% | 96.8% | 3.2% |
| Binance Pool | 2.5% | 22ms | 1.2% | 96.3% | 3.7% |
| SlushPool | 2.0% | 35ms | 1.8% | 96.2% | 3.8% |
Note: These are representative figures from a Texas-based facility. Your mileage will vary based on location and network setup.
The Transparent vs. Opaque Reporting Problem
Most pools show you:
- Current hashrate
- Shares accepted
- Payout history
But they hide:
- Stale share percentage
- Real-time latency
- Pool-side orphan rate
- Effective hashrate after losses
Why? Because showing these numbers would reveal their infrastructure weaknesses.
A truly transparent pool would show you:
Your Hashrate:
Hardware: 110 TH/s
Pool-Reported: 108.2 TH/s
Network Efficiency: 98.4%
Latency Stats:
Avg: 12ms
P50: 10ms
P99: 45ms
Share Performance:
Accepted: 99.3%
Stale: 0.7%
Rejected: 0.0%
This level of transparency is rare. GalliumHash provides it.
How to Choose a Pool (The Right Way)
Don't just look at fees. Here's the proper evaluation framework:
Step 1: Test Latency
Before committing, test latency to the pool's servers:
ping stratum.pool.com
ping us.pool.com
ping eu.pool.com
Look for sub-20ms average latency. If you're seeing 50ms+, consider a different pool or ask about regional servers.
Step 2: Run a 7-Day Trial
Split your hashrate: 70% to your current pool, 30% to the new pool. After 7 days, compare:
- Effective hashrate (pool-reported)
- Stale share percentage
- Earnings per TH/s
Step 3: Calculate True Cost
Don't just compare stated fees. Calculate real fee:
Real Fee = Stated Fee + Stale Rate + (100 - Effective Yield)
A pool with 2% fees but 96% effective yield costs you more than a pool with 2.5% fees and 98% effective yield.
The Geographic Advantage
Here's a secret: Your location matters more than the pool's brand.
If you're mining in:
- North America: Foundry USA, Luxor, Marathon (excellent infrastructure)
- Europe: Braiins Pool, SlushPool (EU servers)
- Asia: AntPool, F2Pool, ViaBTC (regional dominance)
But even better? Host where the pools have their best infrastructure. This is why GalliumHash facilities are strategically located near major pool server clusters.
The 8% Difference, Explained
Back to our experiment. Setup A vs. Setup B:
- Setup A: High-latency pool (avg 52ms), 2.8% stale rate, Stratum V1
- Setup B: Low-latency pool (avg 11ms), 0.5% stale rate, Stratum V2
The compound effect:
Setup A Effective Yield: 94.7%
Setup B Effective Yield: 98.8%
Difference: 4.1 percentage points
Over 60 days at 1.1 PH/s:
Setup A: 0.2847 BTC
Setup B: 0.3089 BTC
Gap: 8.5%
Same hardware. Same electricity. Different pools. $1,450 difference.
Conclusion: Pool Selection is Infrastructure
Most miners think of pools as a commodity—just a place to point their hashrate. But in reality, pool selection is infrastructure optimization.
The pool you choose determines:
- Your effective hashrate
- Your network efficiency
- Your real costs (stated fee + hidden losses)
- Your Network-Level Yield
And over a year, the difference compounds into serious money.
Choose wisely. Test rigorously. And never assume all pools are created equal.
At GalliumHash, we don't just optimize for one pool. We dynamically route your hashrate to the best-performing pool based on real-time latency, block propagation, and yield data. It's part of how we capture Network-Level Yield.
