Trump is already openly sponsored by Elon Musk and other prominent people who are donating to his campaign, so I would say there are no worries when comes to funding his path towards the white house.
Ideologically, I cannot relate to Trump up to one hundred percent, as he is more authoritarian than I would like him to be, to the point of cheering on literal dictators around the world.
I continue to believe deep down in mind, Trump does not actually support cryptocurrency and only uses it as a buzzword to catch our attention. It seems to be working though.
On the other hand, there is no doubt Kamala Harris would continue with Bidens plans to regulate and limit Bitcoin in the long term, even applying high taxes onto miners, so discourage the hashrate within the country.
One of the the strategies Donald Trump have been using to solicit for votes for himself in the upcoming US presidential election is counter the policies of the incubent president Joe Biden and since one of the policies of Biden is allowing cryptocurrency to thrive in the country, you should expect Trump to implement policies that are contrary to that if he's elected as the president of the US. Like you rightly said, Trump have got men of affluence who are solidly behind him like Elon Musk and many others so he's definitely not lacking in finances but from the look of things, it seems Kamala Harris is getting more of the support from the electorates. Personally, I feel the race is still open for any of the two candidates to emerge at the end of the election
