If anybody doesn't know A. Antonoplous or his YouTube channel:
Introduction to Bitcoin
He is one of the most knowledgeable people in the bitcoin scene and the best teacher in my opinion!
He simplifies to a level of everyday language to any audience but never explaines something wrong and still gives the whole implication bitcoin could have if the experiment survives!
If anybody wants to learn anything about Bitcoin I always recommend him right after the whitepaper.
