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 Metric Bitdeer SealMiner A3 Pro Hydro
$2,760 Upfront cost (MSRP) $7,995
-$0.95 Daily net profit $3.57
-$3,107 Net after 1 year -$6,693
-$3,454 Net after 2 years -$5,391
-$3,801 Net after 3 years -$4,089
Does not pay back at current rates (negative daily profit) Payback period Takes ~6.1 years to pay back at current rates

Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
