As of May 2025, El Salvador is the first and so far the only country in the world to officially recognize Bitcoin as a legal tender. This occurred on September 7, 2021.
Although the Central African Republic (CAR) also made Bitcoin an official currency in 2022, it revoked this decision in 2023. Therefore, currently, El Salvador remains the only state with such status for cryptocurrency.
It is important to note that while other countries may allow the use of cryptocurrencies for payments and have some regulation in this area, they have not granted them the status of legal tender on par with fiat currency.$BTC
