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.
This what we see it is just correction after "halving time". Even if price will go down a bit in next days/weeks it still is good moment/level to buy Bitcoin for long term. $600 at the end of this year is nightmare for me, i suppose it will be over $800 easily..
Everyone is eagerly waiting to see the price of $800 but unfortunately I think it will take some more time to touch that price as I think price will go even lower in coming days.
