My friend sent me this today. I am also a fan of Oliver but when we said "I am going to talk about bitcoin, blockchain and cryptocurrency" I felt like it would be saying to him "Hey, John, come listen to me describe the basic elements of comedy." I appreciate him trying to use his brand of humor to educate otherwise uninformed viewers (I find myself among them with most topics he covers). However, I didn't feel like I had a spare 25 minutes to have a 30,000 ft explanation of a topic I understand well.
