How to choose a crypto card

The headline cashback number is the least useful thing on most card pages. Check these first.

Who holds the money

Custodial cards (Bybit, Crypto.com, Kraken, Nexo) spend from an exchange balance. Convenient, but you carry the exchange's risk. Self-custody cards (MetaMask, Gnosis Pay, ether.fi, Bitget Wallet) leave funds in your wallet until the moment you pay.

The rate you get on day one

Look for the rate with no conditions attached. The big numbers usually need a token stake, a paid plan or a VIP tier, and most come with a monthly cap. 4% capped at $60 a month stops paying after $1,500 of spend.

What the reward is paid in

USDC or USDT holds its value. BTC moves with the market. An issuer's own token (CRO, WXT, B2M, ZOOM) carries the most risk: 8% paid in a token that halves is 4%.

Fees that cancel the cashback

A 1-3% FX fee wipes out most rewards when you spend abroad. Also check ATM fees, top-up fees and weekend FX markups.

Whether it is issued where you live

"Many countries" never means every country. Issuers exclude sanctioned jurisdictions, and US residents usually get a separate product. Check the issuer's country list before applying, or start from the country pages.

How the score works

No-strings cashback (40%), maximum cashback (20%), no annual fee (13%), FX fee (8%), country coverage (8%), plus self-custody, IBAN, Apple/Google Pay and travel benefits. Out of 10.

Tips that save money

  • Always pay in the local currency. When a terminal or website offers to charge you in your own currency (dynamic currency conversion), say no. Its rate is often 6% worse, sometimes 12%, against about 1% through your card.
  • Look at the cap, not the rate. "Up to 10%" often stops at $10 or $20 a month. The calculator shows what you get at your spend.
  • Check what you were charged. Multiply the receipt by the mid-market rate on that day and compare it with the amount taken from the card. Some cards add 2% or more on top of the network rate.
  • Watch small-purchase fees. Some cards charge per purchase under a threshold, for example $0.10 under €25 or $0.20 under $30. On coffee-sized payments that is more than the cashback.
  • Top up on a cheap network. Base, Solana or Polygon cost a fraction of a cent; TRON without energy costs about $2 a time and can eat all the cashback on weekly top-ups. Each card page lists its networks.
  • Pay subscriptions on the website, not in the app. Most subscription rebates do not count App Store or Google Play billing, and some only count the first subscription or the first $70 of it. See AI cashback.
  • "Self-custody" can still mean no key export. Check whether you can export the key or seed. Each card page says so where it is known.
  • Borrowing against crypto instead of selling it can change your tax, depending on your country. Ask a tax adviser before relying on it.

FAQ

What is a crypto card?

A normal Visa, Mastercard or Amex card funded with crypto or stablecoins. The crypto is converted at the moment of purchase, so the merchant receives ordinary money.

Debit, credit or prepaid?

Debit and prepaid cards spend your own balance. Bank credit cards (Gemini, Coinbase One, Robinhood Gold) give you a credit line and usually need a US credit check. DeFi credit cards (ether.fi, XPlace, Nexo) lend against crypto you deposit.

Do I need KYC?

For almost every card, yes: Visa and Mastercard require issuers to verify your identity. A few cards need only a name and phone number, or no ID at all; they are marked "No ID check" and never appear in rankings.

Is cashback taxed?

That depends on your country. In many places, paying with crypto counts as a sale, so you may owe tax on any gain. Ask a tax adviser.

Can I use it everywhere?

Anywhere the card network is accepted. Amex is accepted in fewer places than Visa and Mastercard.

How do you decide which cards work in my country?

Only from the issuer's own country list. If your country is on it, the card is marked available. If the issuer says "many countries" or "selected countries" without a full list, the card is marked unclear for every country: not available, not unavailable, just unknown. If the issuer excludes your country, it is marked unavailable. Where an issuer publishes nothing, we use the DefiLlama crypto card dataset and say so on the card. This is about who can sign up; once you have a card, it pays wherever its network is accepted.
