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.
Be careful in what you are assuming. Trump may not know or may not care about Bitcoin but one of his minions will. Those people at the top hire the smartest people who are good at a wide variety of things. I believe Trump will also have fintech people who could or could not be "pro Bitcoin".
The bottom line is Trump will try to make "America great again". That means more taxes for this to come to fruition, to get more taxes is to regulate some more. To regulate some more is to block and make stuff illegal if the cannot control it.
