What is Dual Pool Mining and How Is It Different From Fallback?

August 24, 2026

You open your miner's Stratum settings. You see a Pool Mode dropdown: Single Pool, Dual Pool, Fallback. Which one do you pick? Here's the honest breakdown — one miner to another, no hype.

What Is Dual Pool?

Dual Pool splits one miner's hashrate across two pools at the same time, by percentage. Set it to 50/50 and half your hashrate works on Pool 1 while the other half works on Pool 2 — both running simultaneously, not one after the other.

Why Use It?

Spread your risk. If one pool goes down, the other half of your hashrate keeps running. You're never fully offline.
Two shots at once. Point one half at BTC and the other at BCH — two jackpot tickets instead of betting everything on one coin.
Your ratio, your call. 50/50, 70/30 — whatever fits your strategy.

Dual Pool does NOT increase your expected earnings. Your hashrate earns the same over time no matter which pool it points to. It's a tool for spreading risk, not a magic trick for bigger returns. Splitting doesn't give you more lottery tickets — it just spreads the same tickets across two draws.

Dual Pool vs Fallback — What's the Difference?

This is where most people get confused. One line to sort it out:

Fallback = only ONE pool runs at a time. The backup kicks in only when the main pool drops.
Dual Pool = TWO pools run at the same time, hashrate split by percentage.

	Fallback	Dual Pool
Pools running at once	1 (backup on standby)	2 (both at the same time)
When backup activates	Only if main pool drops	Nothing “activates” — always running
Your hashrate	100% on one pool	Split by % (e.g. 50/50)
Main purpose	Stay online (uptime)	Spread risk / mine two coins

Think of it this way: Fallback is a backup driver — he only steps in when the main driver is sick, and sits on the bench otherwise. Dual Pool is two drivers running two cars at once — both going at the same time, both with a chance.

Quick example — one 12TH miner:

▸ Fallback: All 12TH mines BCH. Pool dies → whole miner auto-switches to backup, keeps mining BCH. Only ever mining one coin.

▸ Dual Pool (50/50): 6TH mines BTC + 6TH mines BCH. Both coins running at the same time.

It's one or the other — they don't stack. Once Pool Mode is set to Dual Pool, you only get Pool 1 and Pool 2 tabs. You can't add a fallback inside Dual Pool. Want auto-switch on a single coin? Use Fallback. Want to spread across two coins? Use Dual Pool.
