How to Buy Bitcoin & Crypto with Square

You can use Square to buy Bitcoin on CEX.IO by relying on the Square Card, which works like any standard debit card at checkout. You can enter your card details directly or connect it to Google Pay or Apple Pay and complete the purchase through these supported services. U.S.-based users can even buy crypto with a Cash App card, since Square also seamlessly integrates with this service. 

However, the Square app itself is not available as a payment method on CEX.IO. You cannot connect it directly or use its interface to complete a transaction, so all purchases must go through the card or linked wallet.

What is Square?

Square is a financial platform that supports both individuals and businesses with everyday payments, whether that involves sending money, accepting customer transactions, or managing funds through a linked debit card. Many users access these features through the Square payment app, which serves as a central hub for managing transfers and card activity.

Rather than acting as a standalone payment method for crypto platforms, Square works more as an ecosystem built around card-based spending and account management. This distinction is important for anyone looking to buy crypto with Square, as the app itself is not used at checkout on CEX.IO, but the card linked to it can still be used to complete a purchase.

How does Square work?

Square is used by both individuals and businesses, but the way they interact with it differs slightly. Businesses typically use Square to accept payments from customers, whether online or in person. Individuals, on the other hand, use it to manage funds, send and receive money, and spend through a linked card.

In both cases, the core mechanism is the same. Funds are held in a Square balance and can be funded by incoming payments or transfers from a linked bank account. That balance is then accessible through the Square Card, a debit card connected to your account.

Once you have the card, you can use it anywhere standard card payments are accepted. This is where square crypto payments come into play. Even though Square does not integrate with CEX.IO as an app, its card allows you to complete crypto purchases the same way you would with any other debit card.

So while the app itself isn't used at checkout, the card it provides serves as the bridge between your Square balance and platforms like CEX.IO.

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

Even though CEX.IO does not integrate with the Square app, this does not prevent you from using Square for crypto purchases. Instead of the app, you can use the Square Card, which works like a standard debit card at checkout.

You can either enter your card details directly through Instant Buy or link your Square Card to e-wallets. We allow eligible users to buy crypto with Google Pay or Apple Pay and complete the transaction through these services, both of which are supported on CEX.IO.

Step 1: Create and verify your account

To become eligible to use the Square card or other supported methods, be sure to register an account with 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.

During this process, we will require you to:

1. Provide personal information
2. Upload a valid ID document (you can use your national ID, driving license, or international passport)
3. Complete any additional checks if prompted (U.S.-based users typically need to complete a brief questionnaire before completing their identity verification)

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

Once you complete your CEX.IO account creation, log in and head to the Buy Cryptocurrency tab. Here, you can set up your purchase order without using trading interfaces. From the Buy Cryptocurrency menu, you need to:

1. Specify your fiat currency
2. Enter the amount you wish to spend
3. Choose BTC or any other supported asset from the dropdown list
4. Click Buy Crypto Instantly to move forward to the Add Funds page. 

Step 3: Select Your Payment Method

On the Add Funds page, navigate to the Select Payment Methods tab and enter your Square Card details. This includes your card number, expiration date, and security code. Follow the on-screen instructions to complete your payment. 

Step 4: Receive Bitcoin in your CEX.IO Wallet

After your transaction is approved, we will credit your CEX.IO Wallet with the amount of Bitcoin you purchased. In most cases, this happens within seconds, although timing may vary depending on authorization and verification checks.

Once you receive your BTC, you can store them in your wallet, trade Bitcoin on Spot Trading, convert it via CEX.IO Convert, or participate in other services and features available in your region. 

Square transfer fees and limits

When you use Square online payment on CEX.IO, you are effectively making a card payment, so the Square Card follows the same fee and limit structure as any other supported debit card.

For purchases, you can deposit as little as $20 with no upper limit, while fees range from 0.49% to 4.99% plus a service charge, depending on the transaction and verification level. You see the full cost breakdown before confirming, so there are no surprises at checkout.

If you plan to withdraw funds back to a card, limits depend on the network. Visa supports withdrawals up to $50,000 per day, while Mastercard is capped at $2,500 per day, with the same 0.49% to 4.99% plus service charge applied.

If you link your Square Card to Google Pay or Apple Pay, deposits are subject to additional restrictions. You can fund between $20 and $1,000 per transaction, with the same fee range, but withdrawals are not available through these methods.

What other payment methods are available at CEX.IO?

Even though you can use a Square Card for crypto purchases, it is not always the most efficient route. Linking cards, dealing with limits, or relying on third-party setups can add unnecessary steps. CEX.IO supports several direct funding methods that give you more control over how you buy crypto, depending on your setup and location.

(H3) Buy BTC with an e-Wallet

If you want speed and minimal input, e-wallets handle that well. You can buy crypto with Apple Pay or Google Pay by confirming the transaction directly on your device without re-entering card details.

U.S.-based customers can also buy crypto with PayPal (available only in this country). You connect your account once, approve the payment, and the system handles the rest. This route keeps the process quick and reduces the chance of failed confirmations compared to manually entered cards.

Buy BTC with Bank Transfer

If you are not in a rush, funding your account through a bank transfer gives you more control over larger amounts. Depending on your location, you can use ACH, SEPA, Faster Payments, or SWIFT.

Instead of purchasing instantly, you first move fiat into your CEX.IO balance. After it arrives, you convert it into Bitcoin using Spot Trading or CEX.IO Convert. This route suits users who want clearer costs and fewer restrictions tied to card issuers.

Buy Bitcoin with Cash

Cash-based methods are still available if you prefer not to rely on cards or bank transfers. One route is using a Bitcoin ATM, where you insert cash and send BTC to your wallet address. Keep in mind that these machines often apply higher markups.

Another way to buy crypto with cash is through MoneyGram. You can deposit between 10 and 900 USDC per transaction with no deposit fee, then use those funds once they appear in your account. Processing is not instant, but it avoids card-related issues altogether.

Can I Send Bitcoin from Square to My CEX.IO Wallet?

Yes, Square allows users to send, receive, and store Bitcoin through its built-in wallet. If you already hold BTC in your Square account, you can transfer it directly to your CEX.IO Wallet by entering your wallet address and confirming the transaction.

This gives you an alternative to buying crypto on-platform; you simply move your existing Bitcoin instead of making a new purchase.

If you also use Cash App, you can follow a similar approach. You may choose to send BTC from Square to Cash App first, or transfer it directly to CEX.IO, depending on your preferred setup.

FAQ

Does Square accept crypto?

Yes, Square supports Bitcoin within its ecosystem. It provides a built-in wallet that allows users to store, send, and receive BTC, which means you can transfer Bitcoin from Square to your CEX.IO Wallet.

U.S.-based users can also connect Square with services like Cash App. Since the Cash App Card is accepted on CEX.IO, it can be used as another route for completing crypto purchases.

Can I buy crypto with Square on CEX.IO?

You can buy Bitcoin on CEX.IO using your Square Card, either by entering the card details directly at checkout or by linking it to Google Pay or Apple Pay and confirming the payment through those services.

However, you cannot buy Bitcoin with the Square app itself. The app is not supported as a checkout method, so all transactions must go through the card or connected wallet.

Is Square payment considered safe?

Square payment methods are generally considered safe, as they rely on established card networks and include standard protections such as encryption, transaction monitoring, and authentication checks. When you use a Square Card on CEX.IO, the transaction goes through the same security layers as any other debit card payment.

That said, approval still depends on your card issuer. Some transactions may trigger additional verification or be declined based on internal risk checks. To reduce friction, make sure your account is fully verified, your card is active for online payments, and your transaction aligns with your usual spending patterns.

Is Square legit?

There are no widespread concerns about its legitimacy. Most issues users encounter relate to account restrictions or transaction reviews, which are standard across payment providers rather than unique to Square.

How long does Square take to process a payment?

For businesses using Square, customer payments are usually authorized in seconds, while payouts to a linked bank account can take one to two business days, depending on the selected payout schedule.

For individuals using the Square Card, transactions behave like standard debit card payments. When used on CEX.IO, approval usually happens within seconds, and once confirmed, the crypto is typically credited shortly after.

Is Square available in my country?

Square is available in a limited number of regions, including the United States, Canada, the United Kingdom, Australia, and Japan. Features may vary by location, especially regarding card issuance and payment capabilities.

Before using Square for purchases on CEX.IO, check whether your account supports online payments and whether your card is enabled for international transactions.

How to buy Bitcoin with Square in the USA?

In the USA, you can use your Square Card to buy Bitcoin on CEX.IO by selecting card payment at checkout and entering your card details. Since CEX.IO does not integrate with the Square app, the purchase is completed through the card, not the app itself.

You can also link your Square Card to Google Pay or Apple Pay and confirm the transaction through these services, either on desktop via QR code or directly in the mobile app.

If you prefer a more direct route, U.S.-based users can also fund purchases using ACH transfers or bank cards issued by major institutions such as JPMorgan Chase, Citibank, First Citizens Bank, or Wells Fargo.
