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 have the right to sell their coins at any time, because they earned them honestly. If the project owners do not want to see a price dump, then let them pay the bounty hunters in Ethereum, which they received as an investment. And then there will be no problems with a price dump. How do you like this idea?
