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 Gamma | Metric | Bitcoin Space Heater L3 Edition |
|---|---|---|
| $99 | Upfront cost (MSRP) | $499 |
| $0.01 | Daily net profit | -$1.92 |
| -$96 | Net after 1 year | -$1,200 |
| -$94 | Net after 2 years | -$1,901 |
| -$91 | Net after 3 years | -$2,601 |
| Takes ~37.8 years to pay back at current rates | 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.
