Andreas uses language, analogies and humor perfectly, all of which are important for clear communication. He is perhaps the best communicator I have encountered, and that is a heuristic for intelligence. He is also an exceptional public speaker. Andreas understood Bitcoin and its potential more than anyone, and it is becuase of him that so many of us understand it as well as we do today. He is the reason I fell so hard into Bitcoin and was able to understand some of it. I read Mastering Bitcoin 4 times.
