Today there are a lot of information sources. But my three main information sources are this forum,reddit and twitter. Telegram can be pretty useful as well I guess but I don't use it much.
I read the news from 5 major sources. They're all good to get informed about latest market news and project news for me actually.
1. Twitter
2. Cointelegraph, Coindesk etc.
3. Telegram groups
4. Official websites of the projects
5. ICO rating websites
