Selling all at once is never an smart idea as you never know what will be the price of bitcoins in future so even if you are making good profits currently its always good to save some bitcoins for coming days as if price goes higher in future then you can sell your coins at higher profit margins.
People who sold their coins before the activation seems to regret their action now. Bitcoin's price is now in a good mood and hope it continue for the next few days.
Panic selling wont give you anything but a headache. Many listen to fuds as this lead them to panic sell. Their thoughts are everywhere like they cant think normal. I think you should know whether your coins will be for long term or in short term holding.
People who are new to bitcoins will surely get panic when they will see price crashing but those who have enough experience will prefer to hold it for a long term no matter what happens in short term as price ups and downs will always be a part of bitcoin economy.
However, finally bitcoin won the battle and going fast towards his destination. I suggest you not to sale out a single bitcoin. Save it for future.
