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 S19 | Metric | Bitaxe Ultra |
|---|---|---|
| $2,000 | Upfront cost (MSRP) | $79 |
| -$5.11 | Daily net profit | -$0.02 |
| -$3,864 | Net after 1 year | -$87 |
| -$5,729 | Net after 2 years | -$95 |
| -$7,593 | Net after 3 years | -$103 |
| 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.
