However much it rises, I'm not sure it will cross the $600 mark before Christmas.
I have a feeling the price will be good at Christmas time.
Before Christmas bitcoin's price may be stable around the 600 dollar mark. At best i see it go back to 650 at worst maybe around 450 dollar.
Anything is possible with bitcoins either it will go higher or lower in future no one knows, but lets hope that it touches some descent value at the end of the year.
