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 think you don't need to be lazy to find a good ICO because ICO raters is a big help to us to know a good ICO. All you said above is important to know because of that you will know what is good about every ICO project. That's why it's important to research about every ICO to know if it's good or not.
