The situation with regulations is not going to change much in my opinion. The US government will continue trying to add more restrictive regulations and increase its surveillance and control which is something that never changes with presidents.
As for a new shitcoin, there is a high chance some opportunists like Musk will try to create their own shitcoin and being a celebrity they will be able to raise millions of dollars and add that to their wealth.
That has nothing to do with Bitcoin nor will it affect it. What they'll create and push would be like tens of thousands of other shitcoins that were created over the past decade and pushed by many scammers.
The other major contributor is the interest rate cuts in many countries including USA that helps inflation go up and recession go down which is a major contributor to bitcoin price rise.
