I used the transcript from Youtube, here are some quotes from the video:

The blockchain is a technology which is a good technology we actually use it it will be useful lot of different things god bless the blockchain. Crypto currencies and digital currencies I think are also fine you know JP more moves six trillion of dollars around the world every day we don't do it in cash it's done digitally. If we do it digitally with the blockchain so be it but it still be a dollar crypto currency. What I have an issue with is a non fiat crypto currency dollar so crypto sterling euro yen they're all fine

So there is a use case for Bitcoin if you live in Venezuela North Korea if you're a criminal great great product I mean that is better than cash or deposits in that country Cuba
