Selling everything is not an option because its gonna be profitable soon or layer, this means that you are just throwing away money and that is not smart at all.
I would never sell them all....
Selling all of them at once doesn't make any sense as we all know that price will be higher in future so we should manage to save some of them for that point of time to grab higher profits and if you sell all of them now then you will surely regret on your decision when you will see higher price in future.
