Which country legally accept Bitcoin?

I'm quite curious about the current legal status of Bitcoin in various countries. I understand that the regulatory approach towards cryptocurrencies differs significantly from one country to another. Some nations have outright banned Bitcoin and other cryptocurrencies, while others have taken a more lenient stance, recognizing it as a legitimate form of currency or asset. Given this diversity in regulations, I'm wondering if there are any countries that have legally accepted Bitcoin as a form of payment or investment, without any restrictions or special conditions attached. If so, could you please enlighten me on which countries these are and what their specific legal frameworks look like? It would be helpful to know if there are any specific requirements or procedures that need to be followed for Bitcoin transactions to be legal in these countries. Additionally, I'm also interested in knowing if there are any countries that are actively considering legalizing Bitcoin in the near future. Could you provide me with some insights into the current regulatory landscape and any potential changes that might be on the horizon? Thank you for taking the time to answer my questions. I appreciate your assistance in helping me understand the global legal perspective on Bitcoin.
