Going by this antecedents, if he say anything about cryptocurrency now, I believe he will do just that. So Trump will be better for Bitcoin than Biden.
We can’t deny the fact that most likely he is just saying it to gain voters. He knows that Biden pissed off a lot of crypto users so he is drilling more to it by promising good things about bitcoin. Well whether it’s all for politics or not, hopefully if ever he wins, Trump actually does the things he is promising about bitcoin.
