Trump, is not president yet and Bitcoin is doing very fine, I doubt that Bitcoin will be in trouble when he begins his administration. Bitcoin has survived many unfriendliness by many governments policies and regulations, yet it's adoption is still increasing, this is because it's power is in the hands of the holders. That being said I believe that there'll be favorable regulations for Bitcoin in the US, this is because it should be obvious to Trump, that Bitcoin can not be pushed aside, the American people have accepted it.

If it's not Bitcoin it wouldn't be like Bitcoin, no cryptocurrency can threaten it, so whether Trump, and Elon Musk, are trying to push any cryptocurrency shouldn't be a worry to bitcoiners.
