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?

Bounty Hunters can decide when they want to sell their coin's. People have their own preiction and need. So, if they think it Will be better for them to sell their coins as soon as possible maybe they have their own reason. But, if they can be patient more, maybe they can get more income too.
