Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Aisen A1 Pro | Metric | Bitcoin Space Heater S9 Edition |
|---|---|---|
| — | Upfront cost (MSRP) | $499 |
| -$4.44 | Daily net profit | -$2.20 |
| -$1,622 | Net after 1 year | -$1,303 |
| -$3,243 | Net after 2 years | -$2,107 |
| -$4,865 | Net after 3 years | -$2,912 |
| — | 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.
