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.
| Antminer L3+ | Metric | Bitmain Antminer U2L9H |
|---|---|---|
| — | Upfront cost (MSRP) | $3,998 |
| -$1.92 | Daily net profit | -$13.61 |
| -$701 | Net after 1 year | -$8,965 |
| -$1,402 | Net after 2 years | -$13,931 |
| -$2,102 | Net after 3 years | -$18,898 |
| — | 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.
