Profitability Comparison
Antminer AL1
Antminer S21 Hydro
Based on BTC price of $78,208 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Antminer S21 Hydro edges it: 5 of 6 factors go its way (efficacité, hashrate, score de minage domestique, niveau sonore, rapport qualité-prix). Where it pulls away hardest is 1994% more hashrate (16.0 vs 335.0 TH/s). The Antminer AL1 claws back ground on consommation électrique. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.

Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Antminer AL1 | Metric | Antminer S21 Hydro |
|---|---|---|
| $10,000 | Upfront cost (MSRP) | $9,500 |
| -$7.49 | Daily net profit | -$0.81 |
| -$12,733 | Net after 1 year | -$9,795 |
| -$15,466 | Net after 2 years | -$10,089 |
| -$18,200 | Net after 3 years | -$10,384 |
| 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.
