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.
| Antminer S19 Pro | Metric | PiAxe |
|---|---|---|
| $2,500 | Upfront cost (MSRP) | $79 |
| -$3.80 | Daily net profit | -$0.02 |
| -$3,886 | Net after 1 year | -$85 |
| -$5,272 | Net after 2 years | -$92 |
| -$6,658 | Net after 3 years | -$98 |
| 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.
