I myself holding some bounty coins rather than dumping at less value because I believe in bounty coins. I hold bounty coins if the specific bounty meet out their targets means whether they achieved soft cap/hard cap or not or they successfully complete the bounty and apart from this I always read whitepaper or roadmap on that basis I decide whether to hold or sell my bounty coins but my personal opinion is holding is more profitable in long term on the other hand some people dump their coins the moment coin get listed.
