2026 Crypto Card Comparison: Net Rewards Matter More Than Headline Rates

A crypto card advertising “up to 10% cashback” can still be a poor deal after conversion fees, FX costs and reward caps. The more useful questions are how much reward remains after fees, where your funds must be held, and whether the headline rate is permanent or promotional. This comparison focuses on those decisions for readers in Taiwan.

TL;DR

• For most people choosing one card: Pick Ether.fi Cash. Free Core membership includes one virtual card. Direct Pay spends USDC directly, and the first $2,000 of eligible monthly purchases earns 3% USDC. A physical card costs $50.
• For regular AI subscriptions: Compare Plasma One Core. Eligible AI spending earns 5% on the first $250 and 4% on the next $250 each month. It costs $199 per year or requires locking 20,000 XPL for 12 months. Free Lite pays 2% only on the first $500, so Ether.fi Core is still the stronger free tier.
• For substantial AI and flight spending: Consider Plasma One Platinum only if you can use its 10% eligible AI and airline rates and accept locking 150,000 XPL for 12 months.
• For existing exchange users: Start with OKX, Bybit or Bitget. KAST Standard has no annual fee and can be useful when a short-term cashback campaign matches your spending.

S Tier: the strongest all-round option

1. Ether.fi Cash

Ether.fi ranks first because it offers both a simple stablecoin spending path and an optional collateralized borrowing path.

For a deeper decision guide, see the full Ether.fi Cash review, including net rewards after TWD conversion, onboarding steps and risk trade-offs.

• Rewards: Free Core membership earns 3% USDC on the first $2,000 of eligible monthly spending, then 1% and 0.5% in higher bands. ATM withdrawals, rent and property-management payments, and cash equivalents do not earn rewards.
• Payments: Apple Pay and Google Pay are supported. Core includes one free virtual card; a physical card including shipping costs $50.
• Fees: Transactions requiring currency conversion use an FX base rate of about 1%, and Core may add another 0%–0.5%. Standard ATM and network fees may apply. EUR purchases currently have a separate 0% FX beta.
• Two modes: Direct Pay deducts USDC first and LiquidUSD second. Borrow Mode uses assets as collateral, begins charging interest immediately and carries liquidation risk.

Borrow Mode lets you spend without first selling your holdings. The trade-off is immediate interest and the need to keep a safe collateral buffer when markets fall. It does not work like a conventional credit card grace period.

A Tier: compelling benefits with meaningful conditions

2. Plasma One

Plasma One ranks second for its targeted rewards on AI subscriptions, flights and travel spending at the Core and Platinum tiers. The free virtual card is a secondary benefit.

Tier	Requirement	Key rewards	Best for
Lite	Free	2% XPL on the first $500 per month, then 0.1%; one virtual card	Testing Plasma One with light spending
Core	$199/year or lock 20,000 XPL for 12 months	3% on the first $1,000 of general spending; eligible AI: 5% on the first $250 and 4% on the next $250; up to $8/month ChatGPT Go rebate	Regular AI-tool subscribers
Platinum	Lock 150,000 XPL for 12 months	4% on the first $3,000 of general spending; eligible AI: 10% on the first $500; eligible airlines: 10%, capped at $600/year; up to $20/month each for ChatGPT Plus and Claude Pro	High AI and travel spenders who accept XPL lock-up risk

Plasma's added FX markup is 1% for Lite, 0.5% for Core and 0% for Platinum, although Visa FX costs may still apply. All tiers currently start with virtual cards; Core and Platinum physical cards are marked coming soon. Rewards are paid weekly in XPL.

How does Plasma One settle purchases?

The normal flow is to deposit USDT, USDC or USDG into Cash balance and spend up to the amount shown in the app. You do not manually repay every purchase. Avoid withdrawing the entire balance while a hotel, car-rental or other preauthorization is pending. Legally, the card remains a secured account: the issuer may liquidate collateral if an amount due becomes overdue, or if collateral falls below unpaid card charges and is not restored.

For a free plan, Ether.fi Core offers better value. Plasma One Core becomes worthwhile when eligible AI rewards and the ChatGPT Go rebate can offset its $199 annual fee. Platinum is for users who can use its flight, AI-subscription and general-spend benefits together. Category bonuses replace base cashback rather than stacking with it, and subscriptions paid through App Store, Google Play or PayPal do not qualify.

3. Bybit Card

Bybit Card suits users who already keep spending funds in a Bybit Funding Account. The workflow is simple, but APAC fees and caps make the headline rate less attractive.

• Spending non-fiat assets in APAC adds a 0.9% conversion fee, while FX is about 2%.
• Cashback ranges from 2% to 10%, but Base is capped at 5 USDT per month. Higher rates require VIP status or much higher monthly spending.
• APAC supports Google Pay but not Apple Pay or Samsung Pay.
• The first $100 of ATM withdrawals each month avoids Bybit's ATM fee; the excess costs 2%. Physical-card eligibility and limits vary by tier.

The card page's “up to 8%” figure refers to variable Flexible Easy Earn yield, not ordinary card cashback.

4. Bitget Wallet Card

Bitget offers virtual cards and an APAC physical card. The physical card costs $49 including international shipping.

Bitget Wallet Card is a top-up card rather than direct point-of-sale spending from a self-custody wallet. Its self-custody model applies before top-up; you must move funds into a separate Card balance before spending. The virtual card supports Apple Pay and Google Pay, so start with a small purchase to test authorization, rewards and refunds before loading more than you plan to spend soon.

The current program gives cardholders a base 2% assetback rate. New users or cardholders who meet specified monthly spending thresholds can receive up to 3%. Rewards may be selected from BTC, gold, certain stocks or indices, and USDC. Merchant-category exclusions, refunds, individual caps and upgrade thresholds still apply, so check the app before relying on the headline rate.

For TWD purchases, the APAC fee schedule lists a 1.7% FX fee for non-USD transactions and approximately 0.05% for crypto-to-fiat conversion. On that simplified basis, 3% assetback leaves about 1.25% after those two fees, while the 2% base rate leaves about 0.25%. This estimate excludes gas, exchange-rate movements and any other charges, making the card better suited to a small trial than an immediate default card.

Shareuhack reader welcome offer: The link below automatically binds the invitation code shareuhack. You can also open the card first, then go to Home → Invite Center → Bind invitation code within seven days and enter shareuhack. Manual binding is available only if no other invitation code is already linked, and the code cannot be changed afterward. According to the campaign information provided by Bitget's partner, new users who make a purchase of at least 5 USDC by August 31, 2026 receive a random 0.2–20 USDC reward; applying for a physical card with the code adds another 5 USDC. Eligibility, deadlines and distribution are subject to the linked page or app.

5. OKX Card

OKX Global Card is a virtual Mastercard linked directly to OKX Pay Wallet, making it a practical option for users who already hold stablecoins there.

• It connects to OKX Pay Wallet and supports USDC, USDT and USDG.
• Mastercard converts the merchant currency into USD, then OKX deducts stablecoins at the current rate plus a 0.1% spread. Accepting DCC can add extra cost.
• The virtual card supports Apple Pay and Google Pay but not ATM withdrawals.
• Cashback is paid in USDG, while the rate and eligibility may be changed by OKX. Do not treat a current campaign rate as permanent.

B Tier: usable, but with weaker net value or trust

6. MEXC Card (APAC)

MEXC Card is an APAC virtual card. New accounts receive an initial M-Score of 350 on the next day, which can qualify for Standard, but month-end cashback uses the actual dynamic score. Trading volume, platform activity, assets and security standing affect that score.

• The virtual Visa has no issuance or annual fee and spends USDT from MEXC Fiat Account.
• The spending fee is 1%. MEXC's Support page says non-USD purchases have no added FX markup, while another official fee guide lists a 1% cross-border fee and an inactivity fee. Check the current card-fee page in the app before spending.
• During the campaign, Standard earns 4%, Premier 6% and Elite 10%, capped at 100, 300 and 800 USDT per month.
• The Rewards FAQ states that cashback, 7% APR and referral rewards apply only during the campaign and may be changed or cancelled later.

This card is best for existing MEXC users who accept exchange-custody risk and will reassess it after the campaign. Do not assume 4% is permanent or move a large balance onto the platform solely for the card.

7. Pionex Card

Pionex currently offers only a virtual card; its physical card has not launched. Apple Pay, Google Pay and LINE Pay are supported. Those wallets are not unique to Pionex—the bigger limitation is that its 1% reward roughly offsets its 1% purchase fee.

• Purchases cost 1% and ATM withdrawals cost 2%.
• Eligible non-USD and general USD purchases currently earn 1% USDT. Specified MCCs, regions and ATM transactions earn no cashback.
• Purchases of $1 or less, unsupported-merchant failures and other non-exempt failed payments cost 0.2 or 0.5 USDT after the applicable official free allowance is used.
• Initiating a transaction dispute (chargeback) costs 50 USDT per case regardless of outcome; losing Visa arbitration adds 600 USDT. The main account must have at least 650 USDT available to be temporarily frozen before filing.

USDT held in the card account currently earns 5% APR, but the rate can change and should not be added directly to card cashback when comparing cards.

8. Crypto.com Card

Crypto.com is established and feature-rich, but its terms vary substantially by jurisdiction. Its Rest-of-World prepaid program offers Basic 0%, Plus 2%, Pro 3%, and Private 4% or 5%. The “up to 6%” rate belongs to the separate U.S. Visa Signature credit card.

Airport lounge access, ATM limits, top-ups, FX and mobile-wallet support must all be checked in the regional App Fees & Limits. Unless you already use the Crypto.com and CRO ecosystem, the complexity remains hard to justify.

9. KAST Card

Standard has no annual fee and pays 1.5% USD on the first $2,000 of monthly spending. Premium costs $1,000 per year for 2% USD plus 1% Points; Private costs $10,000 per year for 3% USD plus 2% Points. Apple Pay and Google Pay availability varies by region.

Reserve is the more important recent change. On September 15, 2026, KAST's site listed introductory annual reward rates of 8% for Standard, 10% for Premium and 12% for Private. Premium rewards apply to balances up to $50,000, Private up to $200,000, while Standard is listed as uncapped. A $10 balance starts earning daily rewards into the Spending balance. The principal is not locked and can be moved out or spent directly.

KAST calls the 8%–12% payments promotional rewards, not bank interest. It says the subsidy comes from company revenue and its corporate balance sheet. Reserve is not a bank account and is not insured. The membership agreement allows the boost to end by June 30, 2027, or earlier once total Reserve deposits reach $100 million, and the rate can change afterward. The headline rate is attractive, but the balance remains custodial with KAST and its partners. It is not a reason to move an entire emergency fund onto the platform.

Reserve makes the free KAST account more useful, while short campaigns add most of the extra value on card spending. During the 2026 Matchday campaign, a correct match prediction doubled the user's base cashback for 24 hours starting shortly after kickoff. Every tier received the same multiplier, but the final rate still depended on its usual cashback rate.

The End of Summer Sale runs from August 13, 2026 at 00:00 UTC through September 30 at 23:59 UTC. Eligible shopping, dining and travel purchases earn 5% cashback, capped at $100 per person. That covers the first $2,000 of eligible spending.

Every membership tier receives the same 5% rate and cap. The campaign replaces the ordinary rate rather than adding five percentage points. Merchant eligibility depends on MCC, and the campaign has a limited total budget, so confirm that it still appears in the app before spending.

Recent community activity is another point in KAST's favor. Several September posts said KAST granted a complimentary one-year Premium membership or upgraded selected users to Private, and the official account amplified some of those reports. That is a good sign for how KAST treats early and active users. Prediction games and other short cashback boosts also give existing cardholders a reason to keep the free card available. These grants have no published general eligibility, so do not count on a free extension or upgrade when applying.

KAST Standard costs $0 per year, and the first two virtual cards are usually free. A card left unused for more than 30 days may be deleted, so keeping the account does not guarantee that the card number will remain active. KAST's official fee page also lists a $0.50 charge when insufficient balance causes a decline. Pionex is therefore not the only provider that charges for failed or declined payments.

New users should start with the free Standard tier and see whether Reserve and the campaigns fit their routine. Looking only at the published Reserve rate difference, Premium adds two percentage points over Standard. Keeping the full $50,000 eligible balance for a year would add $1,000, exactly the annual fee. Private adds four percentage points over Standard; even the full $200,000 cap produces an $8,000 difference, below its $10,000 fee. That rough comparison excludes an early rate change, taxes and platform risk.

The extra card cashback and Points on paid tiers can improve the result, but the answer depends on personal spending, monthly reward caps and whether the card perks are useful. KAST cancelled the expected standard token launch and is only exploring a future participation structure. Its legal notice explicitly says Points are not currently equity, tokens, ownership or guaranteed payment. A complimentary upgrade is easy to welcome; paying out of pocket deserves much more scrutiny.

C Tier: only for specific use cases

10. RedotPay

The free plan is still expensive: a virtual card costs $10 and a physical card $100. Purchases may include a 1% crypto conversion charge plus 1.2% FX for non-default currencies, so check the app quote before applying.

RedotPay Pro costs $12.90 per month or $129 per year and pays 3% in USDs on eligible Apple Pay and Google Pay purchases, capped at $18 per month. USDs expire after 30 days and can only be spent by card, not withdrawn or transferred. The low cap and membership fee make it a poor primary card for high spending. Small-transaction fees start with the sixth qualifying transaction per month, while declined-payment fees start with the fourth.

Bybit	A	2%–10%; Base cap 5 USDT	APAC FX 2% + crypto conversion 0.9%
Bitget Wallet	A	2% assetback; up to 3% for new users or after meeting spending thresholds	About 1.7% TWD FX + 0.05% conversion; requires a separate Card balance
OKX	A	Current campaign terms	0.1% spread; virtual card only
MEXC	B	Campaign 4%–10% USDT; M-Score required	Adjustable rewards; 1% spending fee; exchange custody

RedotPay	C	Free plan none; Pro 3%, capped at $18	High issuance and conversion/FX costs

Five checks before applying

1. Choose the settlement model: Use Direct Pay if you want to spend stablecoins directly. Consider collateralized modes only if you accept interest and liquidation risk.
2. Calculate net rewards: Subtract conversion, FX, purchase fees and reward caps.
3. Separate promotions: APRs, welcome rates and merchant bonuses expire or have eligibility requirements.
4. Test refunds and support: Start with a small purchase and test payment, refund, dispute and card-freeze flows.
5. Limit platform exposure: Keep only near-term spending on exchange cards. Maintain a safe liquidation buffer for Ether.fi Borrow Mode and enough Cash balance while Plasma One transactions are pending.

How to make the final choice

If you want one card for everyday spending, compare Ether.fi Core first. If you pay eligible AI subscriptions every month, calculate whether Plasma One Core's extra rewards can recover the annual fee. Consider OKX, Bybit or MEXC when you already keep funds on those exchanges. Bitget Wallet Card is an alternative for users who want to start from a self-custody wallet and test a free virtual card, although only near-term spending should be moved into its separate Card balance. With KAST, the free Standard tier can stay available for Reserve and relevant campaigns without committing to a paid card.

Run the full calculation before applying: subtract purchase and FX fees, respect the reward cap, and decide how much asset exposure you will accept on the platform. Keep only options with positive net rewards and tolerable custody or liquidation risk, then test the winner with a small payment and refund.
