Bounties are free money to those who collect them. I guess most of it will be dumped right away and therefore bring about some price pressure. But that is temporary.
Hello mv1986, you are thinking quite right of in theory, but in practice the influence of Bounty payments is very low. Let me prove this.
1. OAX daily trade volume = near 300K OAX (https://coinmarketcap.com/currencies/oax/)
2. Bounty tranche = near 10K, most bounty hunters believe in the project and prefer to keep OAX, so, don't know, maybe up to some tens % decided to sell tokens right here right now. Let's concider 3K OAX.
3. 3K to 300K = 1%
I think the influence of 1 additional percent during 1 day is equal to almost zero. And can be not counted at all.
