I always check their website and team as well. How about you guys? Do you go by suggestion or do you do research on the ICO?
for me i check the feature of the coin what is the benefits of using it and what problem it will solve
then check the price of the token and the max supply if the token is not overprice that can become good investment
and then check the team if it have atleast 15 member but if the coin have good feature more than 10 is still good
