Miscommunication and media have the potential to be a strange type of insider trading. Want to buy in? Make bitcoin look bad and hype people to sell out. Want to sell high, release an article praising bitcoin and raising awareness. Not to say it is the case in this miscommunication but the potential is there. If bitcoin builds traction I think we will see some high level media driven pump and dumps.
And the problem lies then with the people holding bitcoins. If they are so stupid to dump their bitcoins because they think the price will fail with the "bad" news , then we have a problem with the average Joe that invested his money. And I'm not talking about people who use bitcoins in daily life , cause most of them are sane enough not to believe that "bitcoin is dead" , Abandon ship!!!!!
