Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Bitaxe Supra | Metric | PiAxe |
|---|---|---|
| $89 | Upfront cost (MSRP) | $79 |
| -$0.01 | Daily net profit | -$0.02 |
| -$91 | Net after 1 year | -$86 |
| -$94 | Net after 2 years | -$94 |
| -$96 | Net after 3 years | -$101 |
| 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.
