Looks like he is getting into your nerves. Don't be. Because that's his intention, to bash bitcoin so that guys like you would be so annoyed that you want to sell your coins. Don't be swayed by his tirade on bitcoin. Let him do that. And the moment that he open his mouth again, its another publicity for bitcoin. And besides, we already proved him wrong because the price is going strong and even brewing for a bull run in the next coming weeks.
I'm sure he's gonna attack once more, but we already know his goal, to pull back the price again. But we won't let him do that because we have matured enough not to listen to him.
