Yeah, it is obvious because demand of its usage will increase and that means more liquidity in the market and more people will buy Bitcoin so simply the demand of it comes with an increase on its price.
Actually the overall price Fluctuations is due to supply and demand when there are large number of people buying bitcoin then price rise but when large number of individuals decide to sell their asset then it adversely effect the price of bitcoin. Previously people were not ready to buy bitcoin but now if they heard about halving so they are buying more bitcoin as a consequence of which the price of bitcoin get bigger and they will now buy bitcoin at larger price as compared to those who have bought bitcoin in 2022.
It varies as per these governments have their own ways of dealing Bitcoin. Some don't really like it as it's said that it's used by criminals as if cash isn't. But that depends with the consensus per government.
Some Government has stopped the use of bitcoin as they assume that it is used for illegal activities so if bitcoin transaction become banned then illegal activities will also be easily removed from one country. Without doubt it can be says that all people are not using it for illegal activities but few are doing it which put bad image on others too. May be there comes a time when each and every country start accepting bitcoin but till the date it is not an acceptable currency all over the world.
