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.
| Aisen A1 Pro | Metric | Antminer S19 |
|---|---|---|
| — | Upfront cost (MSRP) | $2,000 |
| -$4.45 | Daily net profit | -$4.38 |
| -$1,625 | Net after 1 year | -$3,600 |
| -$3,250 | Net after 2 years | -$5,199 |
| -$4,876 | Net after 3 years | -$6,799 |
| — | 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.
