What Is a Bitcoin ATM (BTM)?

A Bitcoin ATM or Bitcoin Teller Machine (BTM) is a terminal that allows users to buy or sell cryptocurrencies using cash or a bank card. It looks similar to a traditional ATM but connects not to a bank network — rather to the blockchain.

Through these machines, you can:

• Buy crypto with cash;
• Sell crypto and receive fiat money;
• Send BTC to another wallet address via QR code.

Bitcoin ATMs are now available in malls, gas stations, airports, and shopping centers. According to Coin ATM Radar, there are over 30,000 Bitcoin ATMs installed worldwide — and that number keeps growing.

How Bitcoin ATMs Work

The mechanism is straightforward. A Bitcoin ATM connects directly to the blockchain and the operator’s wallet. When you insеrt cash, the ATM creates a transaction and sends the equivalent amount of BTC to your specified wallet address.

If you sell crypto, the process reverses — the ATM receives BTC from your wallet and issues fiat cash to you. The entire process takes just a few minutes.

Example: You insеrt $100 → the ATM displays the exchange rate → a blockchain transaction is created → you receive BTC minus the operator’s commission.

What You Need to Use a Bitcoin ATM

Before you start, make sure you have:

• A crypto wallet — for example, Trust Wallet, BlueWallet, Coinbase Wallet, Exodus, or Binance Wallet.
• A BTC wallet address and QR code (found under the “Receive” section in your wallet app).
• Cash or a bank card (depending on the machine’s capabilities).

Tip: Open your wallet and save the QR code before heading to the ATM. It’s much safer than typing the address manually.

How to Find a Bitcoin ATM Near You

Finding a nearby Bitcoin ATM is simple. Use one of these popular services:

• Coin ATM Radar — shows global ATM locations, supported coins, fees, and limits.
• Bitcoin ATM Map — ideal for searching by country or city.

Step-by-Step: How to Buy or Sell Bitcoin

Step 1: Prepare Your Wallet

Install a Bitcoin wallet app if you don’t already have one. Generate your BTC address and keep the QR code ready for scanning.

Step 2: Locate a Nearby ATM

Use Coin ATM Radar to find the nearest terminal. Check which coins it supports and whether it allows both buy and sell operations.

Step 3: Choose an Operation

On the screen, sеlect Buy Bitcoin or Sell Bitcoin.

Step 4: Enter the Amount

Specify how much cash you want to insеrt or withdraw. The systеm will show the current exchange rate and total BTC value.

Step 5: Scan Your QR Code

Scan your wallet’s QR code. This step ensures your BTC goes to the correct address and prevents typing errors.

Step 6: insеrt Cash

Feed your bills into the machine. After confirmation, the ATM sends the crypto to your wallet. The transaction usually appears on the blockchain within 10–15 minutes.

Step 7: Confirm the Transaction

Check your wallet to make sure the funds have arrived. You can verify the transaction using the Blockchain Explorer.

Fees and Limits

Fees vary by operator and region but usually range from 10% to 23%. Some providers apply separate fees for deposits and withdrawals.

Most ATMs have transaction limits between $10 and $10,000, depending on local regulations.
