now is not the time to hold back but it's time to sell, the price of bitcoin now can say is high, so that's why it's better to sell it, but if it predicts that prices will rise again bitcoin, then hold it until the price goes up
too late to sell, if the price falls you have to have patience, usually a layman would be frightened when the price falls,
stay calm and remain hold, because bitcoin prices will definitely go up and down
