News in the cryptocurrency community can be extremely unreliable and designed to influence trading negatively or positively so most people stick to sources they can really trust.
Day/Swing Traders - They use Telegram channels(Whalepool, Whaleclub, Bitstash, Coinfarm) for their discussions and pick their news from subreddits(r/btc, r/bitcoin, r/bitcoinmarkets, r/Ethereum, r/ethtrader).
Developers - Slack and Telegram. Reddit and Twitter for their news
It's not exclusively crypto-related, but they dedicate substantial coverage to developments in the whole crypto/blockchain/ICO space.
They generally approach it from a finance point of view, so it's required reading if you're interested in anything more than just the technological aspects.
