The best thing to do is to accompany with the crowd or person who are knowledgeable about ICO's because you can learn from them don't be Hype by other's who just promote but no experience with ICO's and much better if you do your own research about the concept of the company and how the tokens will work for the future don't just depend on the review sites, you will feel it if the coin looks promising because at the end of the day you are the one who will decide on what is best for you
