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

My advice, if you want to choose a good ICO, then you have to search the internet. There are many informative websites and blogs about ICO, and that you can read and learn. Just browse them, you will have enough knowledge so you can choose a good ICO to invest. After that, you will get experience from your trade.
