And on the flip side, if Trump got mad at the Bitcoin whales (say they didn't donate enough) he could threaten to outlaw Bitcoin in the USA and send the price down by about 80% in a single day, with just a few words from the President of the US.
In other words as far as Bitcoin is concerned, he'll be like Elon Musk on steroids! One day hyping bitcoin up, so price goes up and silly people are happy about it. The other day when he realizes he can't control the decentralized Bitcoin he'll start the FUD and price crashes and silly people realize they were fooled...
