It's true that people can still make money from scams but they need to be quick in getting in and out before the door shuts. Those who came in last are the poor victims.
Getting in as fast as they can is by dumping the coin at the ICO price to make their immediate profit. Note, these large holders does not sell all, and at a very long run, the price starts bouncing back. Those who comes in last, and they are patient with holding, they gain even more than the heavy dumpers.
