A quality project will not be overly affected by dumping anyway. Demand is the key, if more people are looking to dump a coin than buy it, then it shows a lack of confidence, doesn't really matter whether it is bounty hunters or investors. Virtually no ICOs have debuted on exchanges higher than their ICO price since the beginning of the year, which only demonstrates the current lack of confidence in the market as a whole. Can't really blame bounty hunters for that, especially as only a small percentage of coins make their way to them anyway, and normally at least a month after they have already been trading. Once confidence starts to build up again, I'm sure we will see more positive moves, just not on useless projects.
