As full time or part-time bounty hunters identifying best bounties are very important since there is a tendency of increasing scam ICO''s now. Here I am giving some attention to following factors when choosing good bounties.
1. Rating- If the ICO has some rating. If this rating is good or high it is a indication that this is a good ICO.
2. Managers of the bounty- some managers has good reputation such as Amazix , Kripital etc.
3. The team behind the team -IF the team is strong and capable with good track record it is a indication that the bounty and ICO will succeed.
These are the main points come into my mind.
Those are some good points there. I dont know about rating scores by reviewers, i dont know how biased they are, and i hope they are not and are neutral on the insight they provide. Bounties are harder nowdays, a lot of them dont pay, or pay poorly
