Bitcoin can't be in trouble in the hands of Trump who is widely perceived as its messiah but regulation is not what he will do anything drastic about, he knows better to tread carefully not to hurt the crypto community and also his country.

As a whole, Trump will not do anything so important with crypto as widely believed and his cooperation with Elon Musk may not create a new crypto as you hinted. Though they are entitled to it, they will proceed carefully at this point.

On the other hand, Trump might make sure the US's CBDC is eventually birthed, that's the best I see in his administration. I hope it will not hurt the existing financial businesses in the US which is the concern of the present administration.
