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.

No business runs without advertisement. If they are paying tokens for free then see how much profit they are earning. We promoting the ICO's through social media like facebook and twitter where they find many investor to join their project. I would surely say that advertising through bounty is profitable since am doing this and earning.
