First, he is more a developer rather than founder, two different things. Second, wise move from his side. I would also dump @that-price if I had bag which equals to his. More advanced and sofisticated entitities are ready to take a lead and he had feelings of that.
Imho it's not a good from the trust perespective if the biggest coin holder and founder drops all his belonging at the all time high, looks like planned dump and i'm sure we won't see $300 in a distant future, and most likely never.
