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 A3 Hydro | Metric | Whatsminer M53S |
|---|---|---|
| $6,650 | Upfront cost (MSRP) | $8,500 |
| $1.80 | Daily net profit | -$6.86 |
| -$5,994 | Net after 1 year | -$11,006 |
| -$5,337 | Net after 2 years | -$13,511 |
| -$4,681 | Net after 3 years | -$16,017 |
| Takes ~10.1 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.
