One thing with trading entirely is that you will always need every resource you can get your hands on. From news, to what the community of traders are saying about something, the sentiments around and all that, which has made a lot of the news platform like coindesk and cointelegraph, then trading view as a spot where I get to liaise with likeminded traders to see if what you are seeing sometimes, align with what you are thinking. I have never really been a fan of social media when it comes to trading though as you can see a lot of bullshit from afar when it comes to trading in social media platforms.
That is always the thing as there is no limited resources online, but at the same time, you still have to be very careful what you are making use of, as there are some resources, I really do not classify as useful resources at all when it comes to trading considering the fact that you can even get more confused if care is not taken.
Nonetheless, there is so many of them as long as you know what you are researching for. A lot of people tend to look for good books on trading and then while reading use information on the internet to also widen their horizons on what they are reading, so like you said, it is always best to lay hands on as much as possible, in the sense that to thrive, you definitely will need to be able to learn as much as possible.
