No, Bitcoin is not legal everywhere, as its regulatory status varies dramatically across different sovereign nations around the globe. While the vast majority of Western economies, democratic nations, and financial hubs permit the ownership, trading, and commercial usage of Bitcoin under evolving regulatory frameworks, several countries have implemented absolute bans. Nations such as China enforce strict prohibitions on cryptocurrency mining, transactions, and exchange operations, viewing digital assets as a threat to state monetary control, while a few other countries maintain total legislative bans due to anti-money laundering and capital flight concerns.
