Bitcoin will grow naturally with Kamala Harris or Donald Trump as a next President and this question only makes sense if you are citizen of the USA. and a Bitcoiner, then you will have citizen rights to vote for a next President. If you are only a Bitcoiner but not USA citizen, you can not vote.
Bitcoin has been growing in adoption without the friendliness and support that it deserves from past and the present American presidents. So I'm not worried about whether the next American president will be Bitcoin friendly or not because it's doing quite fine on it's growth and it's adoption is increasing nonetheless. I know that the Us government has a major influence in the global economy but Bitcoin doesn't revolve only around them. I believe that many young American bitcoiners will not take sides with their government if they're against Bitcoin.
If I were an American, as a bitcoiner I'll likely vote for Donald trump, probably because of his perceived friendliness towards Bitcoin. But in reality you really never can trust politicians because they'll promise anything to get your votes.
