I just don't see Trump as capable of making the leap here. He's always been obsessed with fiat and has built his rep on embracing it (disclaimer: A relative of mine worked for him in the '80s and has given me some insight I probably shouldn't have). He's also obstinate, not the brightest guy, and looks to be fading a lot mentally right now. I can only really see him embracing BTC in a very fiat-forward way, investing via KYC methods and ETFs and if he accepts BTC donations, openly talking about them and bragging in way that makes his assets vulnerable.
(That said, I could see someone in his orbit using this as a good opportunity to step up some orange pilling.)
