If we ignore all the 'tards and trolls - this is essentially the main downside to NXT.  Each time NXT goes through a rebound the whales start dumping as per typical pump and dump cycles (price rebounds are considered the only time you can dump without potentially killing off the coin).   Considering the number of NXT whales it could take year(s) to clear their holdings and to grow capitalization.

Things are further complicated by the asset exchange where there's a lot of huge capitalization assets (100+ million NXT) which if their volume were to skyrocket then in essence more whales are created and it only adds to the time it'll take to clear the whales.
