$PI No matter which coin it is, when it rises, you should think that it might suddenly turn around and drop at any time, so... so... you need to place sell orders above, and the buy orders below should be hung as at least three segments as a backstop/coverage. If you don’t know how to play, you can only end up as a “leek.” If you can’t bear the losses, then don’t expect to make too much profit—you must take profit and cut losses.
