- Bitmain Antminer S21+ Hyd 100% better weight (17.5 vs 12,700.0 kg)
- Bitmain Antminer S21+ Hyd 59% more heat output (16,326 vs 10,236 BTU/hr)
- Bitmain Antminer S21+ Hyd 100% more home mining score (44.0 vs 22.0)
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 S21+ Hyd | Metric | iPollo B1L |
|---|---|---|
| $2,499 | Upfront cost (MSRP) | $430 |
| $0.13 | Daily net profit | -$5.09 |
| -$2,453 | Net after 1 year | -$2,288 |
| -$2,407 | Net after 2 years | -$4,145 |
| -$2,361 | Net after 3 years | -$6,003 |
| Takes ~54.5 years to pay back at current rates | 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.
