You can refer to the bounty managed by Amazix here:
https://bounties.biz. The projects managed by Amazix are all potential projects worthy of investment. I have participated in many amazix bounties and found this team very professional and enthusiastic. Surely, in the future, there will be a lot of teams like this so no worries when choosing ICO.
Amazix remain the best bounty managers and in fact from the bounties they have managed so far you will find out that they do select those projects that will succeed. Bountyhive is also a good place to select good bounties.
