How do crypto laws differ between countries?

Cryptocurrency regulations vary dramatically worldwide. El Salvador made Bitcoin legal tender in 2021, while China banned crypto trading entirely. The US treats crypto as property for taxes but allows exchanges to operate with licenses. The EU implemented MiCA regulations requiring crypto companies to register and comply with strict rules. Switzerland has favorable crypto laws attracting blockchain companies. Japan regulates exchanges after a 2018 hack but permits trading. India proposed heavy taxation and restrictions. Most countries are still developing frameworks, creating a patchwork of rules. Investors should research their country's stance before trading or holding crypto, as regulations continue evolving and can affect tax obligations, exchange access, and legal status of holdings.
