A bitcoin ATM is the fastest way to turn cash into crypto, and in most cases the most expensive one. It takes bills and sends bitcoin to a wallet address you choose, with the fee folded into the displayed price rather than shown as a separate line. FinCEN, the Treasury’s anti-money-laundering bureau, counted 37,342 convertible-virtual-currency kiosks in the United States on January 1, 2025, up from 4,128 six years earlier. Before you walk up with cash, it helps to know what these machines actually do and where the risks sit.
What a kiosk is and is not
Despite the name, a bitcoin ATM is not connected to a bank account. Three properties separate it from buying in an app. It accepts cash, which is the main reason it exists. The transaction is final: once bitcoin leaves the machine, neither the operator nor your bank can reverse it. And the cost is embedded in the exchange rate, so a buyer can easily miss how much they are paying.
How buying and selling work
Buying follows a common flow. Open the receiving QR code in a wallet you set up yourself, choose an amount, and verify your phone number with a one-time code. Above a threshold, expect to scan an ID and take a selfie. Then scan your own wallet’s QR code, confirm the address on screen matches, insert cash one bill at a time, and review the summary before finishing. If someone sent you a QR code to scan, stop; that is the classic setup the Federal Trade Commission describes in its kiosk-fraud warnings.
Selling only works at two-way machines. You send the exact bitcoin amount shown to the address on screen, wait for a network confirmation, then redeem a code to collect cash. Operators set their own daily limits, so a large sale is usually cheaper and safer through an exchange.
What it actually costs
Buy fees are rarely published as a clean percentage; the markup lives inside the price. The public numbers come from lawsuits and state laws. Iowa’s attorney general alleged that Bitcoin Depot took a 23% cut and CoinFlip 21%, while Washington, D.C.’s attorney general alleged Athena charged up to 26% per transaction. Those are allegations, not court findings. State caps point in the same direction: California caps charges at the greater of $5 or 15%, Illinois at 18%, and North Carolina at 12% from January 2027. On a $500 purchase, a 15% fee means $75 in costs; the same purchase in an app costs a few dollars.
Why regulators keep intervening
The pressure is driven by losses, not convenience. The FBI’s Internet Crime Complaint Center received 13,460 complaints involving crypto kiosks in 2025, with losses of $388,981,267, a 23% rise in complaints and a 58% rise in losses from 2024. More than half of those complaints involved people over 50, who reported more than $302 million of the total. In 2026, Indiana, Tennessee, and Minnesota moved to ban kiosks outright, while California, Illinois, and North Carolina opted for fee caps, daily limits, and fraud screens.
Rules of thumb
Only scan a QR code from a wallet you control. Never send money because a caller claiming to be a government agency, a bank, or tech support tells you to. Check your state’s rules before using a kiosk, and read the machine’s printed scam warning as information about the transaction you are about to make, not boilerplate. For larger amounts, an app or an exchange is cheaper and leaves a paper trail.
