What I look out for are Scam Warnings, Price influencing news and Company Product updates. The most important red flag is the scam warnings. It says it all about an ICO and saves you a lot of troubles. Company updates also tells you how serious and focus a team is. It tells you the latest content offering and technology used.
There is a lot of FUD around though too, how do you make sure a scam really is a scam? Sometimes can it even just be a poorly executed launch?
