Profitability Comparison
Bitdeer SealMiner A2 Pro Hyd
Bitdeer SealMiner A3 Pro Hydro
Based on BTC price of $78,194 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Bitdeer SealMiner A3 Pro Hydro edges it: 2 of 4 factors go its way (efficacité, hashrate). Where it pulls away hardest is 32% more hashrate (500 vs 660 TH/s). The Bitdeer SealMiner A2 Pro Hyd claws back ground on consommation électrique and rapport qualité-prix. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The Bitdeer SealMiner A2 Pro Hyd and Bitdeer SealMiner A3 Pro Hydro diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Bitdeer SealMiner A3 Pro Hydro 32% more hashrate (500 vs 660 TH/s)
- Bitdeer SealMiner A2 Pro Hyd 10% better power draw (7,450 vs 8,250 W)
- Bitdeer SealMiner A3 Pro Hydro 16% better efficacité (14.9 vs 12.5 J/TH)
- Bitdeer SealMiner A3 Pro Hydro 11% more heat output (25,419 vs 28,149 BTU/hr)
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.
| Bitdeer SealMiner A2 Pro Hyd | Metric | Bitdeer SealMiner A3 Pro Hydro |
|---|---|---|
| $4,600 | Upfront cost (MSRP) | $7,995 |
| $0.11 | Daily net profit | $3.95 |
| -$4,559 | Net after 1 year | -$6,554 |
| -$4,518 | Net after 2 years | -$5,112 |
| -$4,478 | Net after 3 years | -$3,671 |
| Takes ~112.7 years to pay back at current rates | Payback period | Takes ~5.5 years to pay back at current rates |
At the default rate, the Bitdeer SealMiner A3 Pro Hydro reaches break-even first — but plug in your own electricity cost above, since payback shifts sharply with it.
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
