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?

Agree, but I think not all bounty hunters will immediately sell tokens after listing on the market. Most bounty campaigns give tokens to bounty hunters after 30 days to 45 days after the sales period so when prices fall when first listing, actually why not from bounty hunters who dumping tokens can be due to other factors
