I want to ask how does the people that do bounty make money.I mean they are giving away money for free.How is it profitable for ICO teams?
Because very less amount of people invest in their ICO through bounty.

some of the ways to promote ICO programs through multiple social media platforms such as facebook and tweeter are the activities that are usually done by some people following the bounty campaign. but the success of the ICO program will depend on several aspects of the ICO team that are developing the bounty program with several concepts that will attract investors.
