- Bitaxe Supra 150% more score de minage domestique (28.0 vs 70.0)
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.
| Bitmain Antminer R4 | Metric | Bitaxe Supra |
|---|---|---|
| — | Upfront cost (MSRP) | $89 |
| -$1.78 | Daily net profit | -$0.02 |
| -$648 | Net after 1 year | -$95 |
| -$1,297 | Net after 2 years | -$100 |
| -$1,945 | Net after 3 years | -$106 |
| — | 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.
