Governments often have issues with Bitcoin for a few key reasons. First, Bitcoin operates outside their control, which makes it harder for them to prevent things like illegal money activities and tax evasion. Also, because Bitcoin transactions don't reveal personal information, it can be tough for the police to track down criminals. Governments are also worried that Bitcoin might compete with their own money, which could cause problems for their economy. Lastly, because the value of Bitcoin can go up and down a lot, it can be risky for regular people who might lose money. So, governments are thinking about ways to make rules for Bitcoin to protect their citizens and their financial systems.
