I found this account:
https://bitcointalk.org/index.php?action=profile;u=1782109;sa=showPostsThis is pretty funny, posts exactly like what kwukduck would say and he is called cryptoduck. Is this an alt account of "teh duck", one of the biggest bears in bitcoin (biggest as in, comically permabear, I don't know how much BTC he has, I think he has 0 and sold them during MtGox and now wants to get back in as cheap as possible).
I predict we will have many kwukducks for a while, then once we start climbing to $100k they will disappear again until the next crash. Enjoy it while it lasts you pesky bears.
