I don't know about you, supporting a president only because he suddenly becomes pro-cryptocurrency (ignoring all his previous actions, his flaws and the fact he is pretty much in legal problems) does not make much sense to me, in the particular case of Donald Trump, people even seem to forget he is kind of a liar and he has kept much of his promises unfulfilled. He can talk all about he wants on how now he loves Bitcoin and cryptocurrency, but if he wins the presidency then he could just do the bare minimum and reduce taxes on miners and Bitcoin holders a bit, that's all. He won't adopt Bitcoin as currency, he won't push for decentralization, and he is likely to continue to push for the implementation of a Central Bank Digital Currency. Because in the end, both Donald and Joe are the same dinosaurs trying to appeal to a young audience and voters by talking about stuff they don't really care about.
They are not Bukele, who kind of understand Bitcoin and it's benefits.
Trump only cares about cryptocurrency and is talking about it because he know it is a section of the voting population which has been ignored and even mistreated by Biden.
