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?

what the meaning cause that ico die? you alright about participants of bounty sell their coins it will make coins dumped. but it not one and only reason that make ico die. if the coins of ico really interest and have potential, the trader will interest and buy it such some coins of ico many trader buy the coins because the coins have good potential
