The Bulgarian lev is the official currency of Bulgaria. It is abbreviated as BGN and is subdivided into 100 stotinki. The lev has been in use since the late 19th century and has undergone several changes, including a period of hyperinflation in the 1990s. The currency is managed by the Bulgarian National Bank, which ensures its stability and value. The lev is pegged to the euro, which helps maintain a stable exchange rate. Coins and banknotes come in various denominations, making it easy for people to conduct everyday transactions.
