exactly the reason. that one big greedy mouth will one day chomp a bulk of waves more than it can handle while the devs are about to leave the waves project and give it to someone else greedier.
this ain't a good picture.
Usually large amounts like that gulped up all at once is just a whale selling to himself... with the idea of creating a dump (which did occur). Although really, it doesn't matter either way. Neither situation is a good one... either it was a real sale, so a whale dumped into the dev, or the dev dumped to himself.
Guess the dev playing manipulation games is actually the better alternative when I think of it, at least it means he's still in control of the price.
