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.
| Antminer Loki Edition (S9) | Metric | Bitcoin Space Heater S9 Edition |
|---|---|---|
| $349 | Upfront cost (MSRP) | $499 |
| -$2.74 | Daily net profit | -$2.21 |
| -$1,348 | Net after 1 year | -$1,305 |
| -$2,347 | Net after 2 years | -$2,111 |
| -$3,345 | Net after 3 years | -$2,917 |
| 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.
