You can take part in several bounty campaigns organized by the project, the average project that develops the ICO program will hold a bounty campaign for promotional tools, bounty campaigns and airdrops are the right way to get paid or get coins for free without investing, so you can follow suit the rules that have been determined, but you have to be patient waiting for payment
maybe around 90 percents from ico project help bounty campaign.although some of them give small allocation to us.and its payment depend on developer decision , it can be faster and maybe need long time to wait our token distribution.
