I'd search for videos on youtube and read articles on medium about btc.
Good luck with that. Google videos and medium about Bitcoin and you get Bitcoin parodies, Bitcoin price speculation and all the nonsense about Bitcoin. I'd stick to the wiki, read a few of the old posts on this forum, and maybe one of those books by one of the Bitcoin greats. So much noisy people making noise on youtube I wouldn't know as a newbie who to listen to.
