I tink that bounty campaigns is how many people do and what they do here around the forum. My view is that you can earn a lot if there are not many participants and if company who host ICO really does good job so after the few months of ICO if it's a good one you will end up earning a lot of money compared to the amount of work you put in. This all depends but is a good way to get into cryptocurrency and to indirectly join ICO without buying and investing in them.
