Due diligence and proper research is a must for doing a campaign. Maybe out of 50 that you work for only 4 or 5 are legit ICOs. You need to make sure that the project you support is a good one with real potential and people behind it. Also, do a campaign that more higher on their bounty budget. You cant expect to earn more than 5k usd just by social campaign. That's swarming with hunters, do some blog or signature this could change your earning.
