Just because he didn't support Bitcoin before doesn't make him a wrong candidate, neither does it mean he can't change. People tend to misunderstand Bitcoin at first and always oppose the idea of cryptocurrency in general, until they really get to understand it. Take a look at some well known figures that publicly spoke against Bitcoin and how they later changed after they got to learn and understand what Bitcoin is all about. I believe Trump is on that path of understanding right now. May the best candidate win.
