Many people do not understand offer and demand, how it really works.
If all bounty hunters would like to sell all their tokens (2% of total supply) it is a huge selling pressure. If there are not enough buyers, price is going down until encounters buy orders. And as you can guess, noone wants to buy ICO coins just after the ICO sale because those who wanted buy, they already bought.
Your point of view?

I think the developer and the team will have a solution to prevent the dumps that will happen after their token listed on the exchanges. But if they don't have, then it is hard for them to keep the price is at a normal price because as you said, the price will going down deeper. I think that happens so far, and it's already happening with almost all tokens listed on the exchanges. If the project is a good project, then they will survive, and even they can pass the bad situations so the price can slowly to increase to the higher price.
