This page explains what each approach requires, where the real costs are, and when home mining makes sense.
What Each Approach Requires#
Home Mining
- Electricity: 18.3 cents per kWh (US residential average, July 2026, EIA)
- Noise: ~75 to 85 dB continuously
- Heat: ~3,500W+ thermal output
- Electrical: dedicated 20A 240V circuit (possibly panel upgrade)
- Insurance: separate hardware policy
- Operations: you monitor and manage
Hosted at Fathom Labs
- Electricity: $0.07/kWh all in (miners bought from us)
- Noise: facility handles it
- Heat: facility handles it
- Electrical: facility handles it
- Insurance: separate hardware policy (not included in the installation fee)
- 24/7 NOC monitoring included
The Electricity Cost Gap#
The most important cost difference is electricity rate. On a 3,500W miner:
| Scenario | Rate | Monthly electricity (3,500W, 24/7) |
|---|---|---|
| US residential average (July 2026) | $0.183/kWh | $461 |
| Fathom Labs: hosted | $0.07/kWh all in | $176 |
Monthly hours = 720. US residential average = 18.3 cents per kWh for July 2026 (EIA Electric Power Monthly); actual rates vary by state and tier. This is a cost comparison only, not a profit projection.
When Home Mining Makes Sense#
- →
- Very cheap electricity:If you have access to power below ~$0.06 to $0.07/kWh (off grid solar, rural industrial rate, or negotiated business rate), home mining can be cost competitive with hosted. Mining from Taiwan? See the Taiwan home mining vs US hosting cost comparison.
- →
- Learning or experimentation:If hands on access and learning are part of the goal, running a small machine at home makes sense regardless of economics.
- →
- Existing infrastructure:If you already have a suitable outbuilding or garage with industrial grade electrical and ventilation, the upfront cost barrier is lower.
