Well in choosing good ICO you need to read the roadmap, white paper, check if the manager is trusted because in someway the manager for me is matters then check if the project is supported by the community by that the chances of getting a high reward is possible and for sure the ico project is successful also.though some of the manager are not trusth worthy
Right, You can try to join bounty campaign but make sure the campaign you join is a potential project just review it by doing resesrch and asking some people who are joined why they joined what is the unique of the project to different. Start finding and analyzing his own campaign I think should be done. not forever we rely on and always ask what good campaign to follow. look for the project with a great team and have a successful sale as well as the allocation of a campaign that is also great
