Despite the massive growth, advancement and advantages of Bitcoin and most crypto currency, why is it hard for most countries to full accept it is or permit it's exchange?
Bitcoin is not owned and controlled by governments and central banks and Bitcoin is like a threat in view of governments and central banks. With conflict of interest, it is explainable why they don't like Bitcoin and in many years want to do many attacks in order to kill Bitcoin adoption.
They can not kill Bitcoin and its adoption in 2025 and in the future so they changed from restrictions, bans to accept Bitcoin but enforce more laws, regulations for getting more money from citizens through tax. Taxing on Bitcoin investors, traders is like a most important concern of governments globally nowadays when they know that their governments will be challenged, even collapsed if they ban Bitcoin.
