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.
| GMO miner B2 | Metric | StealthMiner |
|---|---|---|
| — | Upfront cost (MSRP) | $199 |
| -$3.83 | Daily net profit | -$0.01 |
| -$1,398 | Net after 1 year | -$204 |
| -$2,796 | Net after 2 years | -$210 |
| -$4,194 | Net after 3 years | -$215 |
| — | 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.
