It is a hard question. There is no guarantee for a successful ICO, so it makes difficult to choose which bounty is trusted. I rarely check bountylord.com, to be honest too many bounties there. I just observe a new bounty in our forum and I think some of them very promising to join. One of them is Tradetex, It guarantees to list the coins yet it is an exchange. At least, the coins will be listed on Tradetex.
