Good question! Can there be some group in the telegram where they actually share such advice?
The number of active users and support in social media and in Telegram will do the talk. That kind of community is measured by the number of people involved and getting into very serious discussions and forums.
For me when an ICO is having a thousand members in the crowd then that ICO is very popular and may hit the red dot when ICO is over.
Search for the list and then find them in discussion groups like telegram.
