- Block Proto Rig 263% more heat output (11,294 vs 40,944 BTU/hr)
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.
| Avalon A1446 | Metric | Block Proto Rig |
|---|---|---|
| $3,200 | Upfront cost (MSRP) | — |
| -$3.10 | Daily net profit | $0.57 |
| -$4,332 | Net after 1 year | +$209 |
| -$5,465 | Net after 2 years | +$417 |
| -$6,597 | Net after 3 years | +$626 |
| Does not pay back at current rates (negative daily profit) | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
