I think that he doesn't have any opinion about Bitcoin and just doesn't care. The question is has he even heard of it. He made his fortune on different way and that is what bothers him.
Don't think that the fact he's been elected will influence Bitcoin in good or bad way.
I agree. probably he said bitcoin to impress people to choose him as a president. but I see he does not really care about bitcoin, and I am not sure he really knows what bitcoin is. even if he was serious about bitcoin, probably he would promote it to the people, but I am not really sure. imo.
