No i dont sell everything maybe i sell some but i left some to wait and gain again if the price get high. But if you need money then go ahead sell them all and if you have time earn again so that you can not miss the time if bitcoin increase.
Well if you are going to sell everything then you don't need your bitcoins already. And that is not going to be a good decision if you are going to sell your bitcoins today, but if you are just going to wait a little bit longer then you are going be able to get good profit as the price of bitcoin is going to increase. Just be patient.
Holding them to sell at higher price is a good decision but its better if we don't sell everything at same point and save some of them for future to sell even at higher and better price.
