Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Bitmain Antminer S21e Hyd (310Th) | Metric | Bitcoin Space Heater S19 Edition |
|---|---|---|
| $1,679 | Upfront cost (MSRP) | $1,299 |
| -$1.36 | Daily net profit | -$2.85 |
| -$2,175 | Net after 1 year | -$2,338 |
| -$2,670 | Net after 2 years | -$3,377 |
| -$3,166 | Net after 3 years | -$4,416 |
| Does not pay back at current rates (negative daily profit) | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
