How to Buy Bitcoin & Crypto with Affirm
Affirm is a buy now, pay later service that allows users to split payments into installments instead of paying the full amount upfront. It does not integrate with CEX.IO as a direct payment method, unlike Google Pay, Apple Pay, or PayPal.
However, Affirm provides access to a physical card issued by partner banks such as Evolve Bank & Trust and Stride Bank, N.A. This card can be used like a standard debit card at checkout. Since CEX.IO supports card payments, it may be possible to use an Affirm Card to buy Bitcoin through this route. Affirm users can also request a virtual card; however, although we accept this type of payment, we generally don't recommend it, as it may cause transaction confirmation issues.
In this guide, we explain how Affirm works, how to use eligible cards for crypto purchases, and what fees, limits, and alternative payment methods to expect on CEX.IO.
What is Affirm?
Affirm is a buy now, pay later provider that lets users finance purchases through short-term installment plans instead of paying the full amount up front. It is not a traditional bank. Instead, it works with partner banks such as Cross River Bank, Celtic Bank, Lead Bank, Evolve Bank & Trust, Sutton Bank, and Stride Bank, which issue loans, accounts, and cards.
As an Affirm payment method, it is designed for retail purchases, not financial services. This means you cannot select Affirm directly at checkout on CEX.IO. To buy crypto with Affirm, users use the Affirm Card, which works like a standard payment card and is accepted.
How does Affirm work?
Affirm payment works by offering you a loan at checkout. When you choose Affirm, the provider or its partner bank pays the merchant upfront, and you repay the amount over time, sometimes with interest depending on your terms. Approval depends on your credit profile, and rates can vary from 0% to higher APRs.
Affirm also offers a physical card, issued by Evolve Bank & Trust or Stride Bank, N.A., that lets you make purchases using the same installment structure.
For Affirm crypto use cases, this setup matters. While Affirm itself does not support crypto transactions, its card can be used like a standard card on platforms that accept card payments, such as CEX.IO.
How to Buy Bitcoin with Affirm
The only way to buy Bitcoin with Affirm on CEX.IO is by using the Affirm Card, which is issued by partner banks and works like a standard debit card. Affirm itself is not available as a checkout method, so all purchases must go through card-supported pathways.
One approach is to use the Affirm Card directly through Instant Buy. Select your asset, proceed to checkout, choose card payment, and enter your Affirm card details to complete the transaction.
Another route is to link your Affirm Card to supported e-wallets. Since CEX.IO allows users to buy crypto with Google Pay and Apple Pay, you can confirm your purchase through your mobile wallet instead of entering card details manually.
How to Buy Bitcoin at CEX.IO: a Step-by-Step Guide
As mentioned earlier, the most intuitive way to buy Bitcoin with Affirm is to use its physical card. This route does not require linking Affirm to e-wallets or setting up additional accounts, keeping things smooth and straightforward.
Step 1: Create and verify your account
Start by signing up on CEX.IO using your email address and setting a secure password. After confirming your email, complete identity verification in your account dashboard or through the mobile app.
You’ll need to:
- Provide basic personal information
- Upload a valid ID document
- Complete any additional checks if prompted
Verification unlocks card payments and allows you to access the full range of platform features. Depending on your region, you may be able to use Spot Trading, Margin Trading (available in select countries only), and CEX.IO Earn, which includes crypto Savings and Staking programs.
Step 2: Open the Instant Buy section on CEX.IO
Once your CEX.IO account is ready, log in and go to the Instant Buy page. Here, you can quickly set up your purchase without navigating trading interfaces.
- Choose Bitcoin (BTC) or another supported asset
- Select your preferred fiat currency
- Enter the amount you want to spend
Before moving forward, you’ll see a full price preview, including fees and the estimated crypto amount.
Step 3: Select Your Payment Method
At checkout, choose card payment and enter your Affirm Card details. This includes your card number, expiration date, and security code.
Review the transaction summary, confirm the payment, and complete any required authentication steps with your card issuer. Approval depends on your card provider and transaction checks.
Step 4: Receive Bitcoin in your CEX.IO Wallet
After your payment is approved, Bitcoin is credited to your CEX.IO Wallet. In most cases, this happens within minutes, although timing may vary depending on authorization and verification checks.
You can then store your BTC, convert it to other assets, or transfer it to an external wallet as needed.
Affirm transfer fees and limits
When discussing Affirm fees, it’s important to understand that Affirm itself does not charge transaction fees for crypto purchases on CEX.IO. Since it is not a direct payment method, all costs are borne by the payment method you use, typically card payments.
If you use your Affirm Card, transactions incur the standard card fee structure on CEX.IO, which ranges from 0.49% to 4.99% plus a service charge, with a minimum deposit of $20. Eligible cards may also support withdrawals, with limits depending on the card network.
If you link your Affirm Card to Google Pay or Apple Pay, the same fee structure applies. However, these methods have lower deposit limits, typically up to $1,000 per transaction, making them more suitable for smaller purchases. Withdrawals are not supported through e-wallets, so you need to use a card or bank transfer to cash out.
What payment methods are available at CEX.IO?
While it may be possible to use an Affirm Card in certain cases, it is not always the most reliable route. Some users rely on virtual cards, which can work in theory but often trigger additional checks or fail during confirmation. Physical cards tend to provide a more consistent experience.
Another point to consider is the nature of Affirm itself. Since it is a financing service, using it means entering a repayment plan. Some users may prefer to avoid this and instead use direct payment methods that do not involve borrowing.
CEX.IO offers several alternatives with a more straightforward purchase flow, depending on your location and preferences.
Buy BTC with an e-Wallet
E-wallets are among the fastest ways to complete a crypto purchase, especially on mobile devices. You can buy crypto with Apple Pay or Google Pay by selecting your asset, entering the amount, and confirming the transaction directly from your device.
For U.S.-based users, you can also buy crypto with PayPal. The process is similar. Head to Instant Buy, choose your order details, select PayPal, and link your account to complete the transaction.
These methods remove the need to manually enter card details and are generally more reliable than virtual cards.
Buy BTC with Bank Transfer
If you prefer not to use cards or e-wallets, you can buy crypto with a bank account. Depending on your region, available gateways may include ACH (U.S.), SEPA (Eurozone), Faster Payments (UK), or SWIFT for international transfers.
This method involves funding your CEX.IO account with fiat first. Once the funds arrive, you can convert them into Bitcoin using Spot Trading or CEX.IO Convert. While this route is not instant, it often comes with lower fees and supports larger transaction sizes.
Buy Bitcoin with Cash
If you want to buy crypto with cash, there are a couple of available routes. One way is using a Bitcoin ATM, where you deposit cash and send BTC directly to your CEX.IO Wallet. However, these services often come with higher fees.
Another method is MoneyGram, which allows you to deposit cash at participating locations and fund your CEX.IO account. Once the funds are credited, you can complete your crypto purchase. Fees are generally low, though processing times may vary by location and transaction volume.

Similarly to Affirm, you cannot buy Bitcoin with Zelle directly on CEX.IO, and neither service is designed specifically for crypto transactions. Still, our platform offers plenty of convenient alternatives worth considering.
