El Salvador has been using Bitcoin as fiat currency for four years and currently holds 6,291.18 BTC

According to BlockBeats, on September 7, 2021, El Salvador officially became the world's first country to use Bitcoin as a legal currency. President Nayib Bukele promoted the El Salvador Congress to pass the Bitcoin Act in June 2021. The bill stipulates that Bitcoin can be used to pay goods, services, taxes, etc., and is ranked as legal tender with the US dollar. The El Salvador government has since launched the digital wallet "Chivo", which allows citizens to store and use Bitcoin, and provides registered users with a $30 Bitcoin reward, and also deploys Bitcoin ATMs nationwide for easy transactions. According to data from the website of the El Salvador Ministry of Finance, El Salvador has increased its holdings of 8 bitcoins in the past 7 days, and its current Bitcoin holdings reach 6291.18 pieces, worth more than US$690 million.
