some ico scam but still a lot of good ico, we can choose ico by reading whitepaper they spend and study it so that we can predict the ico as target which we want
Exactly, that's what we should do before investing in an ICO project. Learning white paper to understand more about the project, then we can search about the team to see if they are known and the project it seems legit or not, Read some reviews, because they can help you so much to know if the project worth invest on it or not, we should be smart nowadays, because there is a Serval of new projects and a few of them can be scammed.
Whitepaper is very important in project but there are other important thing too. Team for example and also product.
And also others but i will not talk it here. Actually the team of the project reflect whether the project is good or scam because the team is very important and need very high experience people to catch the team.
