I don't get it. Why everybody complains on D3 being not profitable ? If you compare it to L3+ and S9, it is more profitable now, but will be about the same by the time november batch hits.
Maybe you get a ROI of 6-9 months. That is still awesome.
You can mine it for an year perhaps.
7nm is not coming anytime soon to asics.
Bitmain might release a D3+ with, say, 20GH but at that point your D3 will have paid for itself and you'll just profit less.
If you're lucky, dash will appreciate and btc will hit 5000+ in the mean time.
I don't get it. Why everybody is crying?!?
7nm chips are in production right now. Why do you think Bitmain flooded the market with their 16nm tech? Out with the old, in with the new. Ya got a whole bunch of dumbasses that paid such high prices for 16nm chips in their ASIC miners, that it will take them 1.5 years to pay the initial cost. Trust me, by then 7nm will be in full bloom and production. So bottom line....you don't know what you're talking about.
No one in the ASIC market can produce 7nm chips. Intel isn't even producing less than 14 nm due to production costs. 7nm chips may exist, but they are not consumer ready, and the ASIC market is a few years behind.
