Bitcoin debit cards like Strike and Fold have no foreign transaction fees and earn Bitcoin rewards globally. This guide covers the best Bitcoin cards for international travel and how to use them effectively.
Bitcoin rewards cards have matured significantly. In 2026, you can earn Bitcoin on every purchase, and signup bonuses alone can net you $150-500 in BTC without any unusual spending.
This guide compares the best signup bonuses available right now.
What Makes a Good Bitcoin Card Signup Bonus?
Unlike airline miles (which expire or devalue), Bitcoin signup bonuses are actual BTC that you hold and benefit from if the price rises. This makes the initial bonus potentially more valuable than the face-value comparison suggests.
Evaluate signup bonuses on:
- Bonus BTC amount — current market value of the BTC reward
- Spending requirement — how much you need to spend to earn the bonus
- Time to meet requirement — how many months you have
- Annual fee — whether it erodes the bonus value
- Ongoing earn rate — the card's long-term value after the bonus

Fold Card: Best for Dedicated Bitcoin Holders
Fold Card is the most Bitcoin-native option. Every reward is automatically converted to Bitcoin and sent to your Fold wallet.
The free tier earns 1% Bitcoin back on all purchases with a $150 signup bonus for $3,000 spent in 3 months — an average monthly spend of $1,000.
The Fold Pro ($149/year) doubles the earn rate to 2% and increases the bonus to $300. If you spend $15,000+ annually, the extra 1% earns $150+, more than covering the annual fee.
Fold also offers a daily Bitcoin "spin" — a small random BTC reward each day for using the app — which adds up over time.
Best for: People who want all rewards in Bitcoin with no complexity.
Gemini Credit Card: Best Earn Rate on Dining
Gemini Credit Card (no annual fee) earns 3% back on dining, 2% on groceries, and 1% on everything else, with rewards paid in your choice of crypto — including Bitcoin.
The 3% dining rate is among the highest of any no-annual-fee card in any rewards category. Pair with strategic dining spending to maximize returns.
Rewards are deposited daily into your Gemini account and can be instantly withdrawn or converted.
Best for: People who spend heavily on dining and groceries and want flexibility in which crypto to earn.
How to Maximize the Signup Bonus
The signup bonus typically requires meeting a minimum spend threshold within 3 months. Strategies to hit the threshold without overspending:
Pre-pay regular expenses: Pay your car insurance, gym membership, or utilities in advance if that's possible without penalty.
Large purchases: If you have a planned purchase (appliance, furniture, travel), time it to coincide with the card opening.
Bill routing: Route all recurring bills through the new card for the 3 months — subscriptions, utilities, anything auto-billed.
Authorized users: Some cards allow authorized users whose spending counts toward your bonus. Add a family member whose spending you'd normally share costs on.
Gift card purchases: Buying gift cards you'll actually use at stores you frequent can count as spending. Some cards exclude this — check terms.
Annual Fee Calculation
Should you pay an annual fee for a better signup bonus and earn rate?
Break-even math for Fold Pro ($149/year):
- Extra 1% earn rate vs. free tier
- Break-even spend: $14,900/year ($1,241/month)
- If you spend over $15,000/year on the card, Pro pays for itself
At 2% on all spending, Fold Pro earns $300 on $15,000 spend. The annual fee brings net earn to $151 — identical to the free card. Above $15,000 spend, Pro wins. Below it, free tier wins.
Stacking Bitcoin Rewards
For maximum accumulation, stack multiple strategies:
- Primary spending card: Use Bitcoin rewards card for all daily spending
- Category bonuses: Use Gemini card for dining/groceries (3%/2%)
- DCA contributions: Set up automatic Bitcoin purchases monthly
- Cashback apps: Use Lolli or Fold browser extension for shopping portal bonuses
- Referral bonuses: Most Bitcoin card programs pay referral bonuses — recruit friends for additional BTC
A household spending $4,000/month could realistically accumulate $600-800/year in Bitcoin rewards through optimized card usage.
Watch Out For
Signup bonus restrictions: Some bonuses exclude balance transfers, cash advances, or certain merchant categories. Read the terms.
Credit pull: Applying for any credit card requires a hard inquiry on your credit report. Too many applications in a short period can lower your credit score.
Reward devaluation: Companies can change reward rates and devalue programs. Unlike airline miles that evaporate overnight, Bitcoin rewards that have already been deposited cannot be taken back — but future earn rates can change.
Tax implications: Bitcoin rewards are generally taxable income in the US at the time received. Track the value of each reward deposit for your tax records.
Frequently Asked Questions
Is there an annual fee for the Fold Card? The base Fold Card has no annual fee. Fold Pro costs $149/year and doubles the earn rate to 2%.
Can I convert Bitcoin card rewards to cash? Most Bitcoin card programs require you to hold rewards in Bitcoin or convert to another crypto. They are not easily cashable — that is by design. Verify this before applying if cash access matters to you.
Do Bitcoin card rewards count as purchases for signup bonuses? No. Signup bonuses require spending on purchases, not reward deposits.
Are Bitcoin credit card rewards insured? Rewards held in your card account are subject to the platform's terms. Once withdrawn to your personal wallet, they are under your control and not subject to platform risk.
What credit score do I need? Most Bitcoin rewards cards require good to excellent credit (700+). The Gemini card has been known to approve borderline scores — check your prequalification first.
Bottom Line
The Gemini Credit Card offers the best no-annual-fee signup bonus with best-in-class dining earn rates. The Fold Card is the best pure Bitcoin option, with Fold Pro being worth it if you spend $15,000+ annually on the card.
Open one card, meet the signup bonus, and decide whether to keep it based on the ongoing earn rate.
