In other words: If you had to choose one real person to represent Bitcoin (in the public or in a debate against other crypto currency representatives), who should it be? (It's clear that Bitcoin isn't led or represented by any single one person officially, which is what makes that question so hard to answer. It's also clear that this is feature, not a bug!)
Nobody can ever replace the influence and the name Satoshi Nakamoto to be representing Bitcoin in any discourse and debates. The man knows everything about Bitcoin but since he is not here with us, I actually do not believe that there should be someone who should occupy this position of being ambassador for Bitcoin. Rather, just like the idea of decentralization, this is a community effort with many people contributing something no matter how little or how big for the welfare and further development of this cryptocurrency.
Andreas Antonopoulos is my favorite public Bitcoin AMBASSADOR. He selflessly shares knowledge and spreads good words about Bitcoin
For noobs, I will recommend his
Youtube channel as a
MUSTI have a deep respect and admiration for this man and if ever there is really that need to choose a very good, well-versed and professional ambassador it should be this guy. However, since I firmly believe that Bitcoin is a community effort and a technology to be safeguarded by a group of people with the same mindset, I am adding the names of Gavin Andersen, Charles Lee, Nick Szabo and Brian Armstrong as possible candidates. Of course, these guys have their own sets of strengths and weaknesses so some people may or may not some of them.
