I think all those benefits would be quite marginal, if even recognizable. Consider that people on TV who speak positively of equities of which they have a stake but don't disclose their position can be fined or jailed for that (at least, I believe so).
Yeah but think about what you are implying. You are basically saying that anyone in the media who owns bitcoins can't talk positively about bitcoins (without always mentioning they have some). I think that's absurd. It's like I would have to mention I own euros every time I say something nice about EU.
