You’ll probably need to resort to multiple sources, depending on your specific concerns (i.e. bitcoin technical principals, usage, trading, mining, hard money, history, news, events, security, and so forth).
In general terms, I’ve found this forum itself to be useful, although it’s reading information here is not a linear guided path, and you need to learn to separate the wheat from the chaff. Books are likely a good source for thematic linear information, and people can recommend a series of them that align more to your concrete areas of interest. Documentaries and video (i.e. by Andreas Antonopoulos) are a good complement, providing they aren’t part of the influencer sphere that will just shill whatever they are being paid to shill.
Getting back to the forum, besides the residing amount of thematic treads, one of the mayor benefits resides in being able to interact with the bitcoin community, and ask whatever you are unsure about out in the open (as opposed to some closed communication through social media which is a high risk practice).
