It seems then that Trump's pro-Bitcoin turn is in earnest. In general I don't trust politicians, and if it's on the campaign trail even less but Trump would be neither the first nor will he be the last to change his stance on Bitcoin (remember Saylor, for example)
While not impossible, Trump most likely doesn't actually support or care much about bitcoin. He knows it's an easy way to earn the support of a group of voters. Also, if he was actually a bitcoiner, he wouldn't be making his own crypto project (
