The official currency of Bolivia is the Boliviano (BOB). It is recommended to exchange your currency for Bolivianos once you arrive in Bolivia. It is also a good idea to have some US dollars with you, as they are widely accepted in Bolivia.

ATMs are widely available in Bolivia, especially in larger cities. Make sure to inform your bank that you will be traveling to Bolivia to avoid any issues with your card being blocked.
Major credit cards are accepted in larger establishments in Bolivia, such as hotels, restaurants, and shops. However, cash is still widely used in Bolivia, especially in smaller towns and rural areas. Make sure to have small bills with you as it can be difficult to get change for larger bills.
