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.

Bitmain Antminer S11 (20.5Th)	Metric	Innosilicon T3 43T
—	Upfront cost (MSRP)	$1,500
-$2.93	Daily net profit	-$3.47
-$1,068	Net after 1 year	-$2,768
-$2,136	Net after 2 years	-$4,037
-$3,204	Net after 3 years	-$5,305
—	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.
