He is a manchild and I bet his only interest in bitcoin is the fact that the Winklvoss twins 'own 1% of bitcoins.' Just like Jobs vs. Gates it has more to do with a pissing contest than any benefit to humanity.
Persoanly I don't think it's a good thing for that megalomaniac to have interest in it.
I kinda agree with you, i just hope he actually does something good for the community and not dismiss it.
