I have no idea how many shares you are holding but it doesn't matter, if you want to ensure you don't lose anything, sell enough shares to get your money back plus some profits (10% - 20% or whatever) then play with "house money" and sell at your comfort level, if the dang thing tanks then at least you've lost nothing, if it keeps going up sell at some at .05, .10, .15... You will probably never sell at the absolute peak, so be happy with what you get and don't worry with what may have been left on the table.... GL. By the way, "gap up" means nothing more than an increase at the open based on previous days close, which this seems almost certain to happen....
