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 S19 XP (140Th) | Metric | Avalon A1446 |
|---|---|---|
| $522 | Upfront cost (MSRP) | $3,200 |
| -$2.19 | Daily net profit | -$3.09 |
| -$1,320 | Net after 1 year | -$4,326 |
| -$2,117 | Net after 2 years | -$5,452 |
| -$2,915 | Net after 3 years | -$6,578 |
| 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.
