This would imply Wolong owns large amounts of PND which I would think unlikely.
It would also mean that he'd be making a loss. Say what you want about Wolong but he isn't an idiot. He may hate us and this coin but he isn't going to lose his investors money trying to restore his ego.
or he is not involved yet, so a big pump might be coming, he has to buy first before he can dump
Yeah exactly, this current dumping most likely isn't down to him.
He might well pump and dump it in the future. I doubt it because of the history etc but wouldn't discount it completely; Wolong only cares about one thing which is making money. If he sees an opportunity to this then he will, regardless of which coin it is.
