What are the biggest sources, channels (YouTube channels/influencers, Twitter accounts/influencers etc, ICO rating websites) online that you use to find out in which ICO to invest in?
The most reliable source is Bitcointalk, a legit project will post or create a thread here, this is to let the members comment on the legality and truthfulness of ICO, I don't trust ICO that do not open a thread here, there are a lot of scam ICO that do not have a thread here, so they will not get caught.
