The headline cashback number is the least useful thing on most card pages. Check these first.
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.
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.
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%.
A 1-3% FX fee wipes out most rewards when you spend abroad. Also check ATM fees, top-up fees and weekend FX markups.
"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.
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.
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 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.
Yes, for every card on this site. Visa and Mastercard require issuers to verify your identity.
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.
Anywhere the card network is accepted. Amex is accepted in fewer places than Visa and Mastercard.
Cards with a published country or region list are matched to it. Cards marked "many countries" are shown everywhere except the US, because most issuers serve US residents with a separate product. Always confirm on the issuer's site.
