As an example - Antminer's Scrypt router (R4?) - which has never earned even close enough to pay for it's cost premium over other devices with no mining in them that have similar performance, much less it's total cost, and at THIS point I think it might be underwater on cost of running the mining chip vs income unless you have FREE electric.
that is because they seriously overcharged for it
the t1 chip which samsung built for halong/inno_silicon
does 16000 gh pushed in a dragonmint
it does 13500 gh at a relaxed speed.
That chip cost under 5 bucks.
Based on 192 x 5 = 960 and black fri price was 1500 for gear
A Samsung smart tv 50 inch costs 749
It has internet
It has a cpu
So a pcb with the chip and a heat sink is cheap under 10
Maybe they bump price to 800
And it mines 70gh using 7 watts.
Does it ever earn 50 bucks . It does not matter as this is a way to put blockchain in the hands of Sony Samsung LG etc.
I see this happening based on 1.4 billion tvs sold worldwide since 2011
