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.
| GMO miner B2 | Metric | Bitaxe Gamma |
|---|---|---|
| — | Upfront cost (MSRP) | $99 |
| -$3.78 | Daily net profit | $0.01 |
| -$1,380 | Net after 1 year | -$96 |
| -$2,759 | Net after 2 years | -$92 |
| -$4,139 | Net after 3 years | -$89 |
| — | Payback period | Takes ~30.1 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.
