There are lot of bounties that are good and potentials, I could say that some are in the IEO which is like this one https://bitcointalk.org/index.php?topic=5164591.0 and also for ICO like this one too https://bitcointalk.org/index.php?topic=5155242.0, Meaning not all IEO and ICO are good and have an assurance that it can give us a good earnings in the end.
