The major factors affecting bitcoin are :
Change in government - it's simply means when another government enter there's will be reduction or addition of some policies.
Political instability - when political system in the country is not stable, everything will get down.
I agree with your first point, maybe you can add those government that doesn't want to give freedom to their people, like China.
However, the second part, is the opposite in my opinion, if there is political instability then people should really go to bitcoin and crypto to hedge their wealth. So before everything goes down and worsen or your local money devalued, it's better to put it to bitcoin.
