Serbian dinar · Bulgaria — Currency exchange map

Bulgaria’s currency is the euro (EUR), so exchange offices mostly serve people bringing US dollars, Romanian lei, Serbian dinars or Turkish lira. Sofia, Plovdiv and Varna have the most offers, with more in Burgas, Ruse and Stara Zagora.
In summer, demand grows on the Black Sea coast, where exchange offices open right in the resort areas. P2P offers let you swap USDT or USDC for euros in cash or by card transfer.
