Investors gets more matured, they understand that there is a bounty and once the bounty hunters will dump, it will affect the value of their investment.
Not good for them as the future of the projects will be affected, so if before, investors will wait until the bounty hunters will dump and they will buy it cheap, now, they are the one who will dump first because they participated early to get the bonus so they can still make profit.
but in my opinion not all bounty hunters directly sell their tokens or coins, sometimes there are also those who store their coins until the price becomes stable. but in reality the coin is getting down and even there is no price, that's what I often do too long to save the bounty coin
