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.

Bitcoin Space Heater S9 Edition Metric Bitdeer SealMiner A3 Pro Air
$499 Upfront cost (MSRP) $4,895
-$2.20 Daily net profit $1.85
-$1,303 Net after 1 year -$4,221
-$2,108 Net after 2 years -$3,547
-$2,912 Net after 3 years -$2,872
Does not pay back at current rates (negative daily profit) Payback period Takes ~7.3 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.
