When I earned my first money with the bounty, people around me (especially my family) asked me where did my money came from. When I told them that it came from bounty campaigns, I saw their puzzled face. So I explain it to them with this analogy: "When politicians are running for office, they always show their faces in public in order for them to remember. They give flyers with their name and platforms in it. ICOs are like politicians and their elections is called bounty campaign. We make the ICO popular by posting in forums, social media sites, and creating videos and article." And they quickly understood it so every time someone ask me about bounty campaign, I always used this analogy. How about you?
Easy to explain, bounty campaigns is you marketing the coins from new companies. They are paying you to carry their logos and information of their project on your account and market it to people who will invest in the project. I do bounty campaign part time and the people who know I have a part time job I just tell them that I am into online marketing
