Why selling everything i dont think that would be very great for the people who having bitcoins because why selling all of them if it dont need to spent all of it. Never sell everything just invest everything.
of course that wouldnt be a really good thing to do right now in my opinion, i would definitely not do that in order not to sell bitcoins
I do not think that you should sell everything at once because you should still save some Bitcoin for the future when the price is going to rise.
If you sell everything and the price is rising again you have no Bitcoin to sell at that point.
That's right its always good to save bitcoins for future as we don't know how high it can go in coming years and if we sell everything at once then we won't be able to get higher profits in future.
