Nope! He does not want out! If he wanted to, there would have been better Way´s, as mentioned by others.
He could even offer LISKHQ His coins for a better Price, instead dumping Lisk to "0" !
Exactly, he's just playing games. If he truely wanted out he would've sold parts of his stash by now. There were a few times a 100btc buy wall popped up and lingered a few satoshi below his sell wall and he didn't sell into it at all.
