If you are a technical analysis trader then you will mainly rely in on what you are seeing on the charts and by there you can already invent your own predictions but if you seek for news related to cryptocurrencies or even general news which you think has an impact on the crypto market then that is already part of fundamental analysis but there is no strict rules on here. You can always do them both.

For crypto news sites, there are lots of them and searching with a keyword like "crypto news site" will already give you massive result but usually sites that you can see first are the one that is more trusted or more popular than the rest of the result page.
