The fee stack is where the gap between marketing and real cost shows up most clearly. Reward rates are always quoted before fees, and for two of the three cards here, the fee structure either directly reduces the net reward or introduces a cost that compounds with heavier use. Below is a breakdown for each card, followed by worked examples.
Gemini Card
- Issuance cost: No separate issuance fee
- Annual fee: None
- Membership requirement: None
- ATM and cash advance fee: $10 or 3% of each cash advance, whichever is greater; ATM transactions and cash advances do not earn rewards
- Crypto reward fee: No fee to receive crypto rewards; later sells or swaps follow Gemini's normal trading or conversion fee schedule
- Foreign transaction fee: 0%
Coinbase One Card
- Issuance cost: No added card fee with active membership
- Annual fee: Requires active paid Coinbase One membership; basic annual plan is $49.99/year; Preferred and Premium plans also qualify
- Membership requirement: Coinbase One membership required
- ATM and cash advance fee: $10 or 5% of each cash advance, whichever is greater; ATM withdrawals and other cash-like transactions are rewards-ineligible
- Crypto reward fee: Bitcoin rewards priced when credited; later sells follow normal Coinbase pricing; Coinbase One trading still has spread
- Foreign transaction fee: 0%
Nexo Card
- Issuance cost: No issuance fee publicly shown
- Annual fee: None, but Loyalty Tier affects benefits
- Membership requirement: None for card access, but tier changes what you earn
- ATM and cash advance fee: Free monthly allowance by tier, then 2% fee with a minimum of 1.99 EUR or 1.99 GBP
- Crypto reward or conversion fee: Credit Mode avoids a forced crypto sale; Debit Mode converts through Nexo Exchange
- Foreign transaction fee: 0.2% for EEA, UK, and Switzerland; 2% for rest of world; weekend FX adds 0.5%
Worked Examples
These examples use realistic monthly spending figures to show how the fee and reward structures interact. The figures are illustrative and based on published rates; individual results will vary depending on merchant coding, loyalty tier, and whether balances revolve.
Gemini Card — $1,500 monthly spend
A cardholder spends $200 on gas, $300 on dining, $200 on groceries, and $800 on general purchases. At published rates that produces roughly $8 on gas (4%), $9 on dining (3%), $4 on groceries (2%), and $8 on other spend (1%), for a total of about $29 in crypto rewards per month. No annual fee applies and the foreign transaction fee is 0%. If the balance is paid in full, the only remaining cost is any trading fee when the reward crypto is eventually sold. At Gemini's standard conversion fee the drag on a $29 reward is small but not zero. The reward also degrades in dollar terms if the received crypto falls in price before the user converts or spends it.
Coinbase One Card — $1,500 monthly spend, basic membership, balance under $200,000
At a 2% bitcoin-back rate on $1,500 monthly spend, the card returns $30 in bitcoin. The $49.99 annual Coinbase One membership costs roughly $4.17 per month, reducing the net monthly reward to about $25.83. Over a full year, gross rewards total $360 against a $49.99 membership cost, for a net of $310.01 — assuming no balance is carried, no cash advances are taken, and Coinbase's pricing on bitcoin sales does not erode the reward further. If the user carries a balance at 29.49% APR, even a small revolving amount cancels the annual reward gain within a few months.
Nexo Card — 1,000 EUR monthly spend, base loyalty tier, EEA
In Credit Mode at the base tier, the card pays up to 2% cashback, returning roughly 20 EUR on 1,000 EUR in spend. Domestic EEA transactions carry a 0.2% FX fee, adding about 2 EUR per 1,000 EUR on cross-border purchases within the region. ATM withdrawals beyond the free tier allowance cost 2% with a minimum of 1.99 EUR per transaction. A user who travels outside the EEA on a weekend faces a 2.5% FX rate (2% base plus 0.5% weekend surcharge), which turns a 2% cashback card into a net-negative on those transactions alone. Collateral risk sits outside the fee stack entirely but represents the largest variable cost for any user running a meaningful credit balance against pledged assets.
