UPSC CAPF – 2017
Japan officially recognized Bitcoin as a legal payment method under its Payment Services Act, with the amendment taking effect on April 1, 2017. This made Japan one of the first major economies to regulate cryptocurrencies positively.
Legal recognition of cryptocurrencies varies significantly across countries, ranging from outright bans to full legal tender status.
China has largely banned cryptocurrency trading and mining. The USA has a complex regulatory environment where Bitcoin is treated as property or commodity by different agencies. India has seen regulatory shifts, but Bitcoin is not recognized as legal tender. El Salvador became the first country to adopt Bitcoin as legal tender in September 2021, much later than the date mentioned in the question.
