When talking about YouTube, Andreas Antonopoulos' channel(https://www.youtube.com/user/aantonop) should really be enough.

As for some others, since last year I've really strayed away from "crypto YouTubers" due to too much clickbait and pump and dumps. Since then, I've always preferred podcasts. Namely:

• What Bitcoin Did: https://www.whatbitcoindid.com/
• Tales from the Crypt: https://talesfromthecrypt.libsyn.com/
• Stephan Livera: https://stephanlivera.com/
• The Pomp Podcast(though he's transitioned into business/investing in general): https://anthonypompliano.com/podcast/

Plus, with podcasts, I can listen to them while doing chores. Time efficiency!
