I think it depends because there are bounties that after being listed in the exchangers will suddenly dump the price so it is now difficult to join the bounties especially if there are many dumpers who are investors or bounty hunters we can not blame them if this is their decision because it is no longer old in bounties after distribution others still continue to hold their coin until there is a good exchanger for their holding coin.
Have tired with loss many coin from bounty campaign after holding, now when receiving bounty campaign coin and get chance for selling I will sell because many coin make me get nothing after holding. We can't trust with owner will guarantee their coin keep going on to higher price and stable coin because they only think how to get profit and left when their coin going down. I found with centra coin after the owner get the problem with government and make coin dump then delist from exchange market.
