What I've learnt about bounties so far
1)many bounty hunters are joining bounties that has huge stake allocations like 300,000$ upward ,some are even after the 1000000$ ones well I've stop hunting for projects that lure hunters with huge rewards as many of them are plain rubbish
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
3)there are few bounty managers that I respect ,they take there job very serious and I always like to follow them ,waiting for them to launch new bounties ,I prefer to join 4-5 projects in a year than promoting shitcoins
The truth is that nearly all bounty hunters have learnt what you listed above but sometimes projects that looks not serious at the initial stage may turn out to be the one with huge reward. Its true that there are some bounty manager with good reputation but sometimes these so called trusted managers do find themselves in deep mess I.e managing of scam ICOs. Therefore, my opinion is that no one is perfect when it comes to choosing bounty.
Yes. I guess we all have experienced being scammed after putting lot of efforts in meeting the required post in every bounty but still end up receiving no rewards. I've also experienced working in a bounty where i think it will end up not meeting its soft cap but to my surprise, it has reached its maximum soft cap and end up giving huge rewards to all bounty hunters.
