Dollar Vigilante/Jeff Berwick is honest/refreshing and holds no punches, while being completely fair about everything he talks about. Best for open-minded individuals. Freedom and decentralized bitcoin promoter.
Tai Zen & Leon Fu are very informative and answer much of what you question about cryptocurrency just from videos.
The Cryptoverse/Chris Coney is a great news and learning channel. Very pleasant and educational.
Adam Meister, The "Bitcoin Meister", The Disrupt Meister is a very Bitcoin buy & hold information source. His beliefs are disciplined and frugal. Its the delayed gratification approach and he makes a lot of sense in many approaches.
