Andreas Antonopoulos is so good at explaining big ideas and concepts. He is the main reason I got into bitcoin and cryptocurrencies. His enthusiasm and optimism of the future of this technology made me very interested in it. He doesn't like to be called Bitcoin Jesus but in my mind he is Bitcoin Jesus. I recommend his book internet of money. I learned a great deal from the book and you want, you can purchase it on openbazaar with bitcoin. The link YouTube video is a question-and-answer with him talking about segwit and scaling issues with Bitcoin.
