What do you mean by "sold out"? if you mean selling all of your Bitcoins, then I guess no one will sell all of his Bitcoin in one go to make more profits, unless he really needs the money.

I am holding my Bitcoin and Altcoins for about 3 years already since the last bull run. I've just sold few of it to sustain my everyday needs and to pay my bills. Selling it all out means you just killed the chance of making profits in the long run. So if you'll hold, you must also know how to take advantage on that.
