If you lost the most of it you have no choice but to stick it up and wait for it to rise then pull it back, but that might not be the case for others. If they lost the most of it they tend to wait for it to rise leaving their money on it for a long time then sometimes the coin they invested in doesn't recover that loss and leaving them losing all their money. The best way for me is to set an amount of loss and win so you can pull it out if you cannot bear to lose that many.
