I think now is not the time to sell your tokens or coins, you better get a better profit, because now the market movement has just increased,
Or you can sell half or partial of your assets and then keep the rest because who knows the price would be keep increasing and you may have a risk to miss the trains by selling all of your assets.
There is no exact moment when you need to withdraw funds, it's every investor decides for himself, if not to be too greedy, you can not get the maximum profit, but always stay in the black
Yes, you can't just tell people to sit down and sell their coins when you said to. Just let them do it by themselves and if I they make a mistake and then it's their fault.
