Bitcoin atm machine on city street at night

Bitcoin ATMs are spreading through urban centers, offering 24/7 cash purchase and sale of cryptocurrencies.

About this subject

Bitcoin ATMs (BTMs) are physical kiosks that allow users to buy or sell bitcoin and other cryptocurrencies using cash or debit cards. Unlike online exchanges, they offer instant transactions and relative anonymity, as many models require only a phone number for low-value operations. The first BTM was installed in 2013 at the Waves Coffee House in Vancouver, Canada. Since then, the global count has grown to over 38,000 units in 2024, with heavy concentration in the United States (about 80% of the total), followed by Canada, El Salvador, and Australia. In Brazil, there are approximately 100 BTMs spread across capitals like São Paulo, Rio de Janeiro, and Brasília, many operated by companies such as Bitcoin Exchange and Athena.

These terminals work similarly to a traditional ATM but connect to a cryptocurrency exchange to execute transactions. The user selects the amount, inserts cash, and receives the cryptocurrency in their digital wallet, usually via a QR code. To sell, the process is reversed: the BTM scans the user's wallet QR code, receives the cryptocurrency, and dispenses cash. Transaction fees are typically higher than those of online exchanges, ranging from 5% to 15%, due to operational and security costs.

The nighttime location of a BTM is strategic: many are placed in high-foot-traffic areas such as convenience stores, shopping malls, and subway stations to ensure 24-hour accessibility. Security is a constant concern; therefore, the machines are robust, with tamper-proof safes and remote monitoring systems. Despite this, cases of vandalism and theft have been reported, especially in regions with lower surveillance. Nighttime lighting and security cameras are common at these sites.

The popularity of BTMs reflects the growing interest in cryptocurrencies as a store of value and medium of exchange, especially in countries with high inflation or currency restrictions. In El Salvador, for example, the government installed dozens of BTMs to facilitate the use of bitcoin as legal tender. However, critics point out that BTMs can facilitate money laundering and tax evasion, leading to stricter regulations in several jurisdictions. Still, for the average user, they represent a physical bridge between fiat money and the digital world of cryptocurrencies.

What are the fees for using a Bitcoin ATM?

Fees range from 5% to 15% per transaction, depending on the operator and amount. They are higher than online exchanges due to maintenance, rent, and security costs of the machine.

Most ATMs are located in well-lit areas with security cameras, but it is advisable to use terminals in busy locations. Some models require identity verification for high amounts, increasing security.
