Crypto card fees, explained.
Crypto card fees stack across five separate layers. Most reviews quote only the headline conversion rate; the real cost on a typical spend pattern is usually two to three times that number. Here is the full breakdown with real numbers and how to keep the total manageable.
The five layers
- Conversion fee — the spread on crypto to the card's base currency. 0% to 2.49% across our coverage. Charged on every spend.
- FX fee — additional spread when your spend currency differs from the card's base currency. 0% to 3%. Charged on cross-currency spend only.
- Network fees on top-up — blockchain gas costs when you fund the card. $0.20 on Polygon to $20+ on Ethereum mainnet.
- ATM fees — separate fee schedule for cash withdrawals, typically higher than spend fees. See ATM fees guide.
- Issuance / monthly / annual fees — one-time card costs ($0 to $100 issuance) plus recurring fees on some cards. Most cards in our coverage have $0 monthly fees.
The fee tables, real numbers
Conversion and FX rates verified May 2026:
| Card | Conversion | FX | Effective total spread |
|---|---|---|---|
| Gnosis Pay (EUR spend) | 0% | 0% | 0% |
| MetaMask Card | 0.875% | 0% | 0.875% |
| Bleap (EUR spend) | 0% | 1.0% | 1.0% |
| Bybit Card | 0.9% | 0.5% | 1.40% |
| Kast Card | 0.5% | 0.5% | 1.0% |
| Wirex Card | 1.0% | 1.0% | 2.0% |
| RedotPay | 1.0% | 1.20% | 2.20% |
| Crypto.com Visa (above cap) | 0% | 0% | 0% to monthly cap, then normal |
| Bitpanda Card | 1.49% | 1.49% | 2.98% |
| Coinbase Card | 2.49% | 3.0% | 5.49% |
"Effective total spread" is what you actually pay on a cross-currency spend. For domestic-currency spend, the FX layer is zero and the conversion fee is your only cost.
The compounding cost, with numbers
Spend $20,000/year cross-currency at each effective rate:
- Gnosis Pay (EUR spend): $0/year
- MetaMask Card: $175/year
- Bybit Card: $280/year
- RedotPay: $440/year
- Bitpanda Card: $596/year
- Coinbase Card: $1,098/year
Across five years of typical travel spend, the gap between the cheapest and most expensive card is the price of a holiday.
How to minimise total cost
- Match the card to the spend pattern. Use Gnosis Pay or Bybit for everyday low-FX spend; RedotPay only when you need the limits.
- Top up on cheap chains. USDT on Tron costs ~$1 to send; USDC on Polygon costs pennies. Avoid Ethereum mainnet top-up unless you have to.
- Decline DCC. At any ATM or terminal offering "convert to your home currency," refuse. Let the card network handle it.
- Stack cards strategically. A two-card setup (one for daily, one for big-ticket) usually beats single-card optimisation.
- Watch the monthly cap on "0% FX" cards. Crypto.com Visa advertises 0% but applies normal rates above the tier's monthly cap. Track your spend.
Hidden fees to watch for
- Inactivity fees on some legacy cards (none in our current coverage but worth checking).
- Failed-transaction fees on Mastercard chargebacks (typically $5-15).
- Top-up minimum amounts that effectively force overfunding.
- Reward token volatility on cards paying in CRO, PLU, WXT, NEXO. The "5% cashback" can become 2% realised if the token drops.

FAQ
What fees do crypto cards charge? +
Five layers: (1) conversion (crypto-to-fiat spread on spend, 0-2.5%), (2) FX (cross-currency spend, 0-3%), (3) network fees on top-up (gas, depends on chain), (4) ATM fees (higher than spend fees), (5) issuance/monthly fees on some cards. The first two are the ones that compound on every spend; the others are one-time or situational.
Which crypto card has the lowest fees overall? +
For EUR-denominated spend in the EU, Gnosis Pay is 0% conversion + 0% FX. For non-EU users, MetaMask Card at 0.875% conversion + 0% FX is the cheapest. Bybit Card at 0.9% + 0.5% is competitive. RedotPay at 1.0% + 1.20% is mid-pack. Coinbase Card at 2.49% + 3% is the highest in our coverage.
Are conversion and FX fees the same thing? +
No. Conversion is the spread between your crypto and the card's base currency (usually USD or EUR). FX is the spread when your spend currency differs from the card's base currency. A USDC-funded card spending in EUR pays both: crypto-to-USD conversion + USD-to-EUR FX. A USDC-funded card spending in USD pays only conversion.
What is dynamic currency conversion? +
A trap at ATMs and some merchants. The terminal offers to "convert to your home currency at our rate" with a 3-8% markup over interbank. Always decline. Let the card network handle the conversion at its standard rate, which is much better. Choose "bill me in local currency" or "decline conversion" at the terminal.
Do crypto card fees count for tax purposes? +
In most jurisdictions, the conversion fee is part of your cost basis or sale proceeds calculation for the disposal. Treatment varies. For practical purposes, keep the card's statements (which show the gross and net amounts separately) and let your accountant determine the correct treatment for your jurisdiction.
