I am not totally depending on ico ratings because some high rating ico is not a legit one there are going on the top because they are creating more alt to vote for their ico. I do my own analysis and by reading their white paper and reviewing the background of their team could helps me to decide which is the best ico for me.

Example of best ico for this yesr is VLB token all the characteristics of being great is on their white paper. They have real based project that will gives good impact to the auto/car industry and they already have ongoing presale, they are giving bonuses for early participation of 30% until march 12, 2018 and beyond that they will giving 20% bonus until their ico. https://vlb.io
