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 Hydro | Metric | Bitaxe Gamma |
|---|---|---|
| $5,000 | Upfront cost (MSRP) | $99 |
| -$7.15 | Daily net profit | $0.01 |
| -$7,608 | Net after 1 year | -$96 |
| -$10,216 | Net after 2 years | -$92 |
| -$12,825 | Net after 3 years | -$89 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~29.8 years to pay back at current rates |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
