My experience tells me that sometimes to sell bounty rewards as soon as it hit the exchange may be a good decision. I have noticed some bounty posters who have complained of not making profit from the rewards after they left it believing it will increase and some reduce to nothing after a while. For me I decide not to regret when I take decision to sell.
They got their reward once the token gets pumped but they were only seeing their token without doing any action. It will better to sell it as soon as when we have got it from the market.
The hunters can sell it as soon as possible and then move it to the promising altcoins.
