Hi guys, there are so many ICOs, such as those listed in
https://www.coinschedule.com. It's pretty hard to review them one by one.
Which elements I need to consider, the team? the product? the promoting technology? or something else?
Thanks for any suggestions

I dont think there is an easy way to figure out which ICO is really good other than researching. but there are some threads in the forum which can help you to predict the future of the projects, you can go in to search board and read them.
