Bitcoin atm machine on city street at night

Bitcoin ATMs are spreading across Brazilian cities, offering cash purchase and sale of cryptocurrencies 24 hours a day.

About this subject

Bitcoin automated teller machines (BTMs) are physical terminals that allow users to buy and sell cryptocurrencies using cash or cards. Unlike online exchanges, these machines offer relative anonymity and instant transactions, often without prior registration. In Brazil, the adoption of BTMs grew rapidly after 2019, driven by the search for alternatives to the traditional banking system and distrust of inflation and currency controls.

Placement on busy public streets, as shown in the image, is strategic. Machines are located in high-pedestrian-traffic areas, often near conventional banks or shopping centers, to attract both curious passersby and serious investors. The most common model in the country is operated by BitcoinTrade, which runs about 20 terminals in São Paulo, Rio de Janeiro, Belo Horizonte, and other capitals.

A technical note: BTMs do not store bitcoins physically. They connect to partner exchanges to execute buy and sell orders in real time. The user inserts cash, the machine checks the current exchange rate, and credits the equivalent amount to the user's digital wallet, usually via a QR code. The reverse process is also possible: the user sends bitcoins to the machine and receives banknotes. Transaction fees range from 5% to 10%, much higher than online exchanges, but the service offers convenience and anonymity.

Despite growth, the sector faces regulatory challenges. Brazil's Central Bank has not yet regulated BTMs, creating legal uncertainty. In 2023, the Federal Revenue Service began requiring crypto operators to report all transactions, but street machines often operate in a gray area. Nevertheless, expansion is expected: experts estimate the number of BTMs in the country could double by 2025, driven by bitcoin's growing popularity as a store of value and payment method.
