Is regulations among the key factors that affects the price of Bitcoin
Price of bitcoin is volatile and any related or non related news can move it to a bit in any direction. Regulations do make it harder for people to buy and sell bitcoin. It increases the financial risks and tax related concerns for normal people. Even for a bitcoin enthusiast, it could mean an unnecessary hassle just for holding bitcoins.
I have even seen crypto millionaires leaving their country to a crypto friendly jurisdiction just to keep their crypto business afloat. But with rising tightening of laws in favor of tracking and taxing crypto, the world could move towards global approaches against crypto.
It is likely this is the posture many governments will take against bitcoin and the market in general, but it is impossible that every government does it, at the end governments are opponents and it is impossible for every single government out there to deny themselves the chances of making money with this market.
Just take a look at tax havens, powerful countries all over the world have tried to force tax havens to charge as much taxes as they do in order to leave rich people with no place to go and play by their ridiculous rules, but they refuse as there is simply too much money on the table up for grabs, this market is the same and there will always be countries interested in offering incentives for bitcoin holders to move there.
