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.
| Innosilicon D9 DecredMaster | Metric | FFMiner Decred D18 |
|---|---|---|
| — | Upfront cost (MSRP) | $500 |
| -$2.31 | Daily net profit | -$0.42 |
| -$845 | Net after 1 year | -$653 |
| -$1,689 | Net after 2 years | -$806 |
| -$2,534 | Net after 3 years | -$960 |
| — | 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.
