16k still too expensive. I would purchase immediately for 10k though.
you may want to revisit

10k is still way overpriced
they are supposed to announce their remaining product line "by the end of the month" unless they miss their second self imposed deadline.
i think they must decide to ship 3x hashpower for the same price or slash prices by a third to live up to their own hype and leave any meat on the bone for their customers... or implement a SERIOUS protection plan. guarantee a return of invested btc, minimum, for anyone to take them seriously.
