I do not think that it is a good idea to be selling all your Bitcoin at the moment because you are not going to make that much money if you do sell them right now.
I should wait for the value of the Bitcoin to go up so that you can get more out of it.
If you have purchased your coins at for say $350-$450 level then you can afford to sell some of them to grab profits, but its not smart move to sell everything at a moment as price will be much higher in future.
I bough most of the bitcoin when the price was $60. I still hold them as I think the price of bitcoin will rise further.
