How to Buy Bitcoin & Crypto with Real-Time Payments

Real-time payments can move money between bank accounts within seconds, which makes them useful when preparing funds for crypto purchases. Instead of waiting days for transfers to clear, you can quickly fund your bank account and continue with supported payment methods on CEX.IO.

However, RTP is not a checkout method on our platform. You cannot directly buy Bitcoin with Real-Time Payments. To complete a purchase, you need to use available routes such as debit or credit cards, bank transfers, or supported e-wallets.

In this guide, we explain how RTP works, how it fits into the crypto buying process, and which alternatives you can use on CEX.IO.

Disclaimer: Real-time payments (RTP) is not a supported payment method on CEX.IO. You cannot buy crypto with RTP directly. It can only be used to transfer funds to your bank account before completing a purchase with available payment methods.

What are Real-Time Payments?

Real-time payments (RTP) allow instant transfers between bank accounts, typically within seconds, 24/7. Unlike traditional systems that process transactions in batches, RTP clears and settles each payment individually, making funds available almost immediately.

This speed helps users move balances quickly, even on weekends, but it does not mean you can buy crypto with Real-Time Payments directly. RTP acts as a funding tool, not a payment gateway. The same goes for FedNow, another RTP payment method which we covered in a separate guide. 

So, you can use Real-time payments to move funds from one account to another, but you can not use it to buy crypto directly. 

How Real-Time Payments Work?

RTP systems follow a straightforward but fast process. You initiate a transfer through your banking app, your bank verifies funds and details, and the payment moves through a real-time network. Both sender and recipient receive confirmation within seconds.

For RTP crypto payments, this means you can quickly prepare funds for crypto purchases. However, the transaction ends at your bank account. From there, you still need to use a supported method, such as a card or bank transfer (ACH for U.S.-based users), to complete a purchase on CEX.IO.

How to Buy Crypto with the RTP App?

You cannot buy Bitcoin with Real-Time Payments directly on CEX.IO, as RTP is not integrated as a checkout method.

What you can do is use RTP to move funds between accounts instantly. For example, you can transfer money to your primary bank account using RTP, then use that balance to complete a purchase with a debit card or bank transfer supported by CEX.IO.

How to Buy Bitcoin at CEX.IO: a Step-by-Step Guide

The most intuitive way to buy Bitcoin at CEX.IO is to use your card, credit or debit. We support cards from JP Morgan Chase, Citibank, Wells Fargo, First Citizens Bank, as well as many other financial institutions in the United States. 

Credit and debit cards are also available to users outside the U.S., and, as long as you use the card issued under your name and have enough balance on it, you’ll rarely encounter any issues during checkout. 

Step 1: Create and verify your account

Sign up on CEX.IO and complete identity verification. You start by creating an account with a strong password and finish by providing personal documents to verify your identity in accordance with KYC/AML regulations.

While you can access your account without verification, you won’t be able to buy, sell, store, or trade crypto until you complete your profile properly.

Step 2: Open the Instant Buy section on CEX.IO

The next step is pretty straightforward. You log in to your CEX.IO account and head on to the Buy Cryptocurrency section on the left-hand side of the user dashboard. From there, you need to: 

1. Specify fiat currency and amount. 
2. Choose BTC from the dropdown list. 
3. Click Buy Crypto Instantly to access the Add Funds page. 

Step 3: Select Your Payment Method

Next, choose from available methods such as debit or credit cards, bank transfers, or e-wallets. You can buy crypto with Apple Pay or Google Pay, even from the desktop-based platform. But keep in mind that you’ll need to confirm your purchase by scanning the QR code, so we recommend preparing your app beforehand to expedite the process. 

If you used RTP beforehand, your bank account should already have available funds.

Step 4: Receive Bitcoin in your CEX.IO Wallet

Confirm your transaction. Once processed, your Bitcoin appears in your CEX.IO Wallet, ready for storage, transfer, or further use.

Real-Time Payments Alternatives

Real-time payments can help you move funds quickly, but they still add an extra step before you can complete a crypto purchase. Instead of routing money through your bank first, you can use payment methods that connect directly to CEX.IO and allow you to buy crypto without delays or additional setup.

Buy Bitcoin with Credit or Debit Card

As mentioned above, the most direct way to buy Bitcoin instantly is by using a debit or credit card. This method removes the need for intermediate transfers and allows you to complete your purchase in one flow.

You simply access Instant Buy, select your asset, and enter your card details at checkout. Once confirmed, your crypto is credited to your CEX.IO Wallet within minutes. You can also save your card for future transactions, which lets you buy crypto faster without re-entering your card details.

Compared to RTP, this route avoids extra steps and gives you immediate execution.

Buy Crypto with e-Wallet

If you prefer a mobile-first experience, e-wallets offer a smoother way to buy crypto with Google Pay or Apple Pay. These services connect directly to CEX.IO and let you confirm transactions on your device.

On a desktop, you can initiate the purchase and then scan a QR code on your phone to approve it. On mobile, everything happens within the app, which keeps the process fast and consistent.

U.S.-based users can also buy crypto with PayPal, which works in a similar way. You select PayPal at checkout, link your account, and confirm the payment.

Buy Crypto with a Bank Account

If you plan to use larger amounts, you can buy crypto with a bank account through supported transfers such as ACH (U.S.), SEPA (EU), or Faster Payments (UK).

Unlike card purchases, this method involves two steps. First, you fund your CEX.IO account with fiat. Once the funds arrive, you can convert them to crypto using Instant Buy or CEX.IO Convert.

More experienced users may choose Spot Trading to exchange fiat for BTC or other assets. However, if you want a simpler route, Convert allows you to swap funds quickly without dealing with order types.

Compared to RTP, this approach integrates directly with CEX.IO and avoids moving funds back and forth between accounts.

Buy Crypto with Cash

If you prefer physical payments, you can buy crypto with cash using supported services like MoneyGram. This allows you to deposit cash at participating locations and have it credited to your CEX.IO account.

Once the funds appear, you can convert them into Bitcoin or other cryptocurrencies. Fees are typically low, though processing times may vary depending on the provider and location.

Another route involves Bitcoin ATMs, where you can purchase BTC directly and then transfer it to your CEX.IO Wallet. However, this method often comes with higher fees.
