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.
I think Amazix has managed some amazing campaigns like Gochain , the team is good but it has been a long time that they haven't posted any new campaigns, they respond questions fast and I had no problem with them , Also I can Suggest bountyhive , It has a great team too but you need to be quick if you want to participate in their campaigns .
I agree with you that Amazix it's a good group of managers who have quite a lot of decent bounty, but also a minus on it, too, can catch.
