Payment Success Rate in Crypto Purchases: What Shapes It

• A single success rate mixes card declines, identity checks, and payment method limits, each with its own causes and fixes.
• Crypto rules differ from bank to bank, so card approval varies from one country to the next.
• Mercuryo's Fast Track lets eligible new users buy below €700 with their personal details, without full KYC.
• KYC sharing and one-time verification help users avoid a repeat check.
• On Mercuryo, Apple Pay and Google Pay accept purchases of up to €2,000, and cards up to €15,000.

The share of payments that are successfully completed end to end, that is, fully settled, according to the Merchant Risk Council's 2026 report. Applied to a crypto purchase, success means the payment is completed, and the crypto is sent to the user's wallet.

Even with a clear definition, the result depends on how attempts are counted. For example, a user wants to buy €300 of bitcoin, but their bank declines the card, so they switch to Apple Pay, and the purchase is completed.

• Counted by tries: one decline and one success.

• Counted by purchases: one completed purchase.

Tracking both tells you how often buyers finish after switching card or payment method.

Card decline rate is the share of card payments that are declined, and the decision to decline is made by the user's bank and card issuer.

Banks set different policies for crypto purchases, and those policies vary by country. The UK shows how wide that range can be.

In January 2026, the UK Cryptoasset Business Council surveyed ten of the country's largest crypto exchanges and estimated that UK banks block or delay about 40% of the payments customers send to them.

The same report also compared individual banks. Its table of British banks shows full access at a few, per-transaction caps at others and outright blocks at several more.

So compare decline rates country by country, because a policy change at one bank can alter the figure for a whole market while your checkout stays the same. When a bank declines a card, the purchase can still be completed with another payment method.

Before paying, users can check our country-by-country guide, which lists the banks with a historically higher success rate on our payments and helps improve their chances of approval.

If a card is still declined, the user has other options. Card, Apple Pay, and Google Pay are switched on by default in the Mercuryo widget.

On top of that, Try Again, which we set up with your team, lets users retry inside the widget without starting over. You decide whether they can change payment method between attempts, for example from card to Google Pay.

For other causes, such as an unfinished 3D Secure step or insufficient funds, our help center has a guide to common payment issues.

Whether a crypto purchase needs an identity check, known as KYC, depends on the amount and our own compliance checks.

KYC conversion rate is the percentage of verifications that users complete. The time verification takes shapes it too, since both depend on how much each user is asked to do.

With Fast Track, eligible new users can buy by entering their personal details while their combined purchases and sales stay below €700. Standard KYC applies once they pass that amount.

If you already verify users through Sumsub, you can share that verification with us, so eligible users don't repeat it. Our Customer Success and Compliance teams agree to the setup with you.

Returning users who have completed KYC with us before don't need to verify again. For users who start the check but leave before finishing, we send an email link to continue and hold the purchase for 30 minutes.

Limits differ by payment method. We accept Apple Pay and Google Pay purchases of up to €2,000 each and card purchases of up to €15,000, our standard limit.

Because of these limits, purchases above €2,000 move to cards or other methods, so the method mix partly reflects purchase size. A product with larger average purchases can therefore expect a higher share of card payments.

An on-ramp should let you see each of these factors. We record a status for every purchase, such as declined by the card issuer, waiting for verification, or paid, and a separate one when the crypto is sent to the user's wallet.

We send these status updates to your systems, and our Merchant Dashboard shows transactions as they happen, with exportable reports and performance by location and currency.

Payment success rate gets easier to improve once you can see where each purchase stops and what helps it complete. Our on-ramp is designed for crypto and fintech products, and an integration manager supports your team through the setup.

If you are planning to add crypto purchases to your product, tell us about your markets and users. We will show you how card approvals, identity checks, and payment methods would work for them.

What is a good payment success rate? It depends on the market, because banks treat crypto purchases differently from one country to another. Compare each market and payment method with its own past results.

Why are crypto card purchases declined? Card payments usually fail because of the user's bank, the payment method, or extra security checks. Typical causes include bank restrictions on crypto and an unfinished 3D Secure step.

Insufficient funds and wrong card details can also cause a payment to fail. Whatever the reason, Try Again lets users retry inside the widget and, if you allow it, switch to another card or method.

Is there a fiat-to-crypto payment gateway with no KYC? We are licensed and required to verify identity, while keeping the check light for small amounts.

For those amounts, Fast Track lets eligible new users in supported regions buy by entering their personal details until their combined purchases and sales reach €700. Above that amount, the user completes standard KYC.

How do I measure KYC conversion? Divide the number of completed verifications by the number of purchases that required one, and track how long those checks took. We give users up to 30 minutes to finish verification while the purchase waits.
