Abstract

Nowadays, online shopping There are many approaches to digital currency. What should you do if you hold a large amount of cash and want to immediately convert it into Bitcoin? You can choose the usual method: deposit cash into a local bank > register on the trading platform and complete identity verification > top up the account > wait for the amount to arrive and finally complete the transaction.

The whole process is very tedious, right? Wouldn’t it be nice if there was a magical self-service vending machine that could directly convert fiat currencies that have easily changed hands into Bitcoin? Happily, such machines already exist. We call it a "Bitcoin ATM" and this tutorial will explain how to use it in detail.

Introduction

Most methods of buying Bitcoin online will associate the user's personal information with the purchase&ndash ; Everything from KYC/AML compliant trading platforms to credit card/bank account information for payment.

One of the easiest ways to buy Bitcoin (BTC) anonymously is to use a Bitcoin ATM. In this guide, we'll walk you through how to buy Bitcoin with cash at a physical ATM, detailing the steps before, after, and during the purchase.  

What is a Bitcoin ATM?

Bitcoin ATMs (automated teller machines) are similar in function to ATMs commonly used to deposit cash into bank accounts. A normal ATM will take your cash and update your bank balance through the IOU (financial claim) mechanism, which you can then use to pay others.

Through Bitcoin ATM machines, your cash can be converted into Bitcoins and then deposited directly into your Bitcoin wallet. Bitcoin ATMs may also often support the purchase of selected altcoins, and some machines also have the option to convert the digital currency into cash!

Preparation

Start with the most important things first! We need to set up a wallet for receiving purchased Bitcoins. There are many wallets to choose from on Android and iOS devices. In this guide, we are using Trust Wallet, other wallets are used in much the same way.

In the wallet App, we need to find the public address. Most apps will display this information when you click the "Receive" button. We’ve chosen to use QR codes in this guide. If you are using a wallet that supports multiple digital currencies, make sure you have the public address for the digital currency you purchased (Bitcoin in this guide).

Next, we need to find the target Bitcoin ATM machine, because we need to actually of traveling there. Fortunately, coinatmradar.com offers a handy interactive tool to help find nearby ATMs. Enter your preferred location in the search field to display local Bitcoin ATMs.

Click on any map marker to view the location of the ATM and the supported currencies. Click "View Details" to learn about quotations, fee schedules, operator details and other information. The most important thing is to see the ratings of other users.

We want to choose an ATM with excellent recent ratings, which should clearly display the owner's contact information and provide a quote and fee schedule. This information is an important basis for us to identify the authenticity of the machine.

The picture above is a Bitcoin ATM. Now, we have a mobile wallet in one hand and cash in the other. Before pressing the button, it is recommended to check the machine and understand how it works. All machines have slightly different layouts (and looks), but the basic functionality is generally the same. In this guide, we use the machine pictured above as an example.

On the right is a touch screen that displays instructions on how to buy or sell Bitcoin. It will display the current trading prices offered by this machine: the selling price is around 9,100 euros; the buying price is around 9,900 euros. (Note: A quick check at coinmarketcap.com shows that the total market price of Bitcoin is approximately €9,600, and earning the difference is how ATM operators make money).

On the left are slots for depositing and receiving fiat currency, a receipt printer, and a QR code scanner for entering addresses.  

Click on the right side of the touch screen (the Purchase side) and select “ BUY”Option (please note that we need to buy Bitcoin, not other altcoins). Different models of ATM machines may have different settings for this option, but the difference is usually only in the external form. The "Buy Bitcoin" option will be placed in a prominent position.

1. Use the ATM's QR code scanner to read the wallet's Bitcoin receiving address, telling the machine where to send the purchased Bitcoins.
2. Check whether the digital address displayed by the machine is exactly the same as the address displayed by your wallet App.  
3. Please put cash into the deposit slot.
4. Set the miner fee you are willing to pay for this transaction to be included in the block (note: some ATMs do not have this feature). The higher the fee, the faster the confirmation.
5. Confirm the purchase information in the wallet and finally complete the transaction.
6. Keep the receipt properly so that it can be documented in case of subsequent problems.

The transaction will then be sent to the Bitcoin network and your wallet will eventually receive the purchased Bitcoins. Please note that Bitcoin needs to be added to a block first, so it will not be available immediately. It usually takes 6 confirmations before final transaction. The single confirmation time in the Bitcoin network is approximately 10 minutes.

After purchase

After purchase, you can use Bitcoin's block explorer (for example: Blockchain .com), track transaction progress by searching for the receiving address or transaction ID. You will see the funds arrive in your wallet balance after 5 to 15 confirmations, depending on which wallet app you use.

Confirmation will occur at least once within the first hour. If your account has not arrived after several hours, you should contact the ATM owner immediately to find out whether the delay is due to normal technical issues.

Summary

Bitcoin ATMs bring convenience and speed to consumers who purchase Bitcoin with cash. As an added bonus, the Bitcoin purchased is not attached to your identity via bank transfer or credit card.

Similar to foreign exchange service providers, the buy/sell prices set by ATM providers often differ from the current market price of Bitcoin. Online tools like coinatmradar.com can help you find trustworthy ATMs with reasonable fees.
