i believe the best ico for April 2018 is Merculet. it creates the User Attention Value (UAV) evaluation system to scientifically measure the value of a user’s attention. An entrepreneur can simply access the UAV system, which can seamlessly integrate with traditional reward-point systems, through a set of open protocols. Merculet is created to lead the transformation of turning the information-based internet into the value-based internet. i think it will definitely improve current situation. if you are interested you can go to their oficial website or thread. you also look it up on icodrops.com
i think the project is nice, so if you are looking for an ico to invest, you can consider participating in Merculet. but make your own research first, read as much info as you can. and only than make up your mind)) good luck!))
