So how many sold because of this prediction? I at least guess op?
those who buy/sell bitcoin because of some random topic on bitcointalk aren't going to be left with any bitcoin/money in a couple of weeks. and at this point the market has already shaken out majority of these weak hand newbies already.
The thing is that people do not buy and sell because there is a bitcointalk topic about a subject, people buy and sell and that is why there is a bitcointalk topic about that subject. You do not understand why people open topics, when people talk about "this will happen" that is usually for the future, but when there is a gap, that gap is basically what happened because that gap was there, the gap didn't happen because there was a topic about it here.
However since there is a topic about it here, it could attract more attention towards itself. Those are very different reasons. Hopefully the gap is now gone and the resistance is higher right now, so I would assume the price could not go up easily anymore, sure it won't go down as easy neither so I think everything is balanced now.
