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.

Innosilicon A4+ LTCMaster	Metric	Elphapex DG1S
$3,500	Upfront cost (MSRP)	$2,800
-$1.80	Daily net profit	-$7.44
-$4,157	Net after 1 year	-$5,515
-$4,814	Net after 2 years	-$8,231
-$5,471	Net after 3 years	-$10,946
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.
