I think that selling everything isn't good decision. Not now, not for the future. I would not feel comfortable to give up all the coins...
Yeah, because our main purpose why we are here is to make money and if we are selling all our coins or bitcoins to be exact, we are just letting the opportunity to earn more and we cannot bring back the time, we should have a strategy like selling a portion of bitcoins and keep the others.
If we intend to sell our all coins then its our decision but make sure that you wont regret on the end when you saw bitcoins price would rise up high. True, bitcoin is an opportunity for us to make more money or profit in upcoming future because it would increase its price and would benefit us all.
