2)I've learn to always join bounties that are already listed and trading with good volume and mind you these bounties always have low bounty rewards like 75k to 100k but there is high assurance of selling your tokens if you wish to ,not keeping coins that will never see the light of the days again ,I mean tokens that will never get listed
joining a bounty that already listed in exchange never guarantee you a good amount earning because if you join it i think many people already join it so the total rewards already small with many people join it you will receive a small reward too
