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.
| Bitmain ANTMINER DR7 | Metric | FFMiner Decred D18 |
|---|---|---|
| $1,639 | Upfront cost (MSRP) | $500 |
| -$2.00 | Daily net profit | -$0.42 |
| -$2,368 | Net after 1 year | -$653 |
| -$3,097 | Net after 2 years | -$806 |
| -$3,826 | Net after 3 years | -$960 |
| Does not pay back at current rates (negative daily profit) | 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.
