Simple answer > None!!

I use multiple platforms like this forum, twitter and few crypto and ico related websites to get news about which ICOs are coming in future. But I use NONE of them to rely upon there performance and value.

Most of the blogs and channels gets paid as in bounty for writing content for the upcoming ICOs, they are never 100% genuine.

If an ICO appears interesting, following are the first few basic steps I use to review about it:

1. Read Whitepaper
2. Check out Team members and advisory board
3. Check Partners
4. Check token metrics
5. Check genuinity of team members, advisors and partners if they are really related to that project.
