We know how respectful this man is because of his many achievements in the world of investment but just like all of us he is still human and therefore not perfect in his many ways...in fact he got it wrong with Google and Facebook before as certainly he is not a big believer with new technologies maybe because he is an old school. And we have to leave him at that. As to his pronouncements on cryptocurrency, we should be looking at Warren as the devil's advocate and we can still learn many things from him on this aspect as certainly nobody knows what can happen next in this very volatile environment and it pays to be careful all the time.
