I am not demotivating or demoralising anyone here but these services are not too trustworthy and one shouldn't be trusting them of the chart. These services are always paid reviews and thus most of the time each and every ICO that is listed here gets the voting more than 4.0 and thus it always feels like we are in the heaven and getting legit ICO to invest.
ICO investment always starts with your own original research. Its not big thing to do, just read out loud about the ICO roadmaps, check for the uniqueness of each ICO, be selective to the whiteapaper and see whether that kind of whitpaper is already present or not. Few simple tricks can lead your investigation to the trusted ICO.
