Stop guessing which coin to solo mine.

SoloOdds watches difficulty, prices, and network conditions across SHA-256 and Scrypt coins — and tells you when to switch, personalized to your actual hardware. No software to install. No dashboards to check.

You're mining blind.

Difficulty adjusts. Prices move. Low-cap SHA-256 and Scrypt coins can see 30–60% difficulty swings overnight — creating short windows where your solo odds improve dramatically. But you're not watching 8 coins across 2 algorithms around the clock. Nobody is.

Right now, your options are:

BTC solo odds calculators — one coin, no electricity cost, no comparison.
Pool profitability tools — built for pool miners, not solo.
Altcoin solo calculators — one coin at a time, no cross-coin ranking.
Mental math to combine the data.
Repeat every difficulty adjustment — or, more commonly, don't.

You end up mining the same coin forever, even when something else temporarily offers 10× better solo expected value for your hardware.

Your solo mining watchdog.

SoloOdds is a free calculator and alert service for home solo miners. It combines your specific hardware, cross-coin solo probability ranking, electricity-cost-aware expected value, and push alerts — all without touching your miners.

Fleet-Aware Ranking

Select your devices — Bitaxe Gamma, Avalon Q, Hammer Miner DC06, whatever you run. SoloOdds ranks every compatible coin by solo expected value for your specific hashrate and wattage. Not generic TH/s inputs — your actual hardware.

“Time to Switch” Alerts

When difficulty drops 38% on DGB and it becomes the #1 coin for your fleet, SoloOdds sends you a Discord or Telegram alert with the numbers: new odds, new EV, what changed. You decide whether to act.
