There is a trend with most (not all but most) ICO. Price drops after ICO from people selling and then goes back up in a couple of days or weeks if its a good project. So people who are trying to make a quick buck is happy and people who are HODL are also happy.
A good example is Monaco. The price after ico fell down. And only after a few months the coin go to the moon. And this is not the limit. Maybe it's just a warm-up.
