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.
