I (and others too, likely you as well, I don't keep track) predicted the dollar would raise in December, back in September or so.
I also predicted the dollar would lower in january (I don't think I mentionned "way down") before going up again in the following months and the month is not over yet.
Will the dollar go lower than 7 by the end of January? Could be, then I would have predicted wrongly that one, anyway, I wouldn't even have a virtual caramelo for predicting right
Now, to predict what the rate will be in december 2013 is a hard task, as it is it should be around 9 but there are many factors.
My comment was just a form of empathy for people making money in pesos (if that was you or I, you'd likely get annoyed reading over and over people happy about the dollar going up), hence maybe the non-need to create multiple threads, nothing else.
