You'll never know when it is because when you're up by 10x-20x or more, you're not going to sell them because you'd think of more that might come to this portfolio of yours. And when the peak comes, you'll not stop and won't take profit because you think that there's a lot more from that more that you've thought of before. Until you're start to notice that the drop has been a lot and the decrease won't stop further and the paper loss that you're having is incredible from the paper profits that you've got before.
