Bybit advertises "up to 10% cashback" on its crypto card. Ether.fi promises "true self-custody" with DeFi yield. Both sound good on paper, but the actual numbers tell a very different story. This comparison uses data from our 170-card database to break down every fee, every cap, and every hidden catch. Read the standalone Bybit Card review or Ether.fi Cash review for full data sheets. See our editorial disclosure.
The custody difference shows up most clearly in the transaction path. Same $100 purchase, two very different sequences underneath:
| Step | Bybit Card (custodial) | Ether.fi Cash (self-custody, Borrow Mode) |
|---|---|---|
| 1. Funds before purchase | Held by Bybit on its exchange balance, in your name | Held in your own Gnosis Safe wallet on-chain |
| 2. You tap the card for $100 | Bybit debits your exchange balance | Wallet borrows $100 USDC against your collateral via Aave |
| 3. Crypto disposal | Bybit sells the equivalent crypto, taxable disposal triggered | No sale, collateral stays on-chain, no taxable event |
| 4. Settlement to merchant | Mastercard rail settles $100 USD to the merchant | Visa rail settles $100 USD to the merchant |
| 5. Cashback | 1% base in the EEA ($1 here, no cap); VIP tiers pay 2–10% with monthly caps | Real 3% at Core rates, paid in USDC |
| 6. Loan repayment | Not applicable | Pay down the Aave borrow with future income or by selling later |
| 7. Tax timing | Capital gain or loss realised on every spend | Tax deferred until collateral sold or liquidated |
The borrow-to-spend mechanic is the structural advantage Ether.fi has over any custodial card. Spending borrowed funds is not a disposal under most tax regimes, including the IRS treatment in the US (though specific DeFi guidance is still evolving). For a long-term holder who would otherwise have to sell appreciated crypto to fund a card, this can defer years of tax events. The trade-off is liquidation risk: if your collateral falls below the loan-to-value ratio, your collateral gets sold to repay the loan, and that forced sale is a taxable event you did not choose the timing of.
One caveat: the flow above describes Borrow Mode. Ether.fi also runs a Direct Pay Mode, where the purchase amount is deducted straight from the USDC or LiquidUSD balance in your vault, with the help centre naming both assets and no order between them. No loan, no liquidation risk. The tax-deferral argument in step 7 does not apply there, since you are spending stablecoins rather than borrowing against appreciated collateral.
Verdict: Ether.fi Cash wins, but the size of the gap depends on your spend.
Bybit fixed its worst problem for Europeans. The EEA card now pays a 1% base rate on eligible purchases with no monthly cap, and VIP holders earn 2–10% on top, subject to monthly caps. Ether.fi Cash still pays more where it counts: a real 3% cashback in USDC on the first $2,000 of Core-tier monthly spend, plus true self-custody, Visa Signature benefits, and availability in 70+ countries (including the US and UK, where Bybit does not operate). At $2,000/month that is $60 against Bybit's $20. Push past the Core threshold and the Ether.fi ladder steps down to 1%, then 0.5%, so a $5,000/month spender lands closer to 1.6x. EUR spending runs on a lower ladder and ends up around 1.6x too.
| Metric | Bybit Card | Ether.fi Cash | Winner |
|---|---|---|---|
| Sweepbase Rating | 3.1 / 5 | 4.9 / 5 | Ether.fi |
| Real Cashback ($2K/mo, EEA) | $20/mo (1% base, no cap) | $60/mo (3%) | Ether.fi (3x at this spend) |
| Custody | Custodial (CEX) | Self-custody (Gnosis Safe) | Ether.fi |
| Countries | ~35 (no US, UK) | 70+ (incl. US, UK) | Ether.fi |
| Card Network | Mastercard / Visa | Visa Signature | Ether.fi |
This kind of head-to-head can quickly turn into a feature-checklist that nobody reads. I tried to avoid that by ranking the dimensions in the order the readers who emailed me actually cared about. Cashback math came first, because the headline 3% rate on one card and the 1% base rate on the other only tells you half the story until you read the tier caps and regional carve-outs. Custody model came second, because once you decide between custodial and self-custody, you can stop arguing about the dimensions that do not matter to your model.
After that the comparison gets specific. ATM availability, fee transparency, the wallet-app experience for someone who is not already a crypto power user, and whether the cashback denomination is liquid enough to be useful. Bybit and Ether.fi are interesting precisely because they sit on opposite sides of every one of these axes. The card you want depends almost entirely on how much you care about controlling the keys versus how much you want to ignore the underlying mechanics and just spend.
| Feature | Bybit Card | Ether.fi Cash |
|---|---|---|
| Card Network | Mastercard (EEA) / Visa (APAC) | Visa Signature |
| Card Type | Prepaid debit | DeFi card (Direct Pay debit or Borrow Mode credit) |
| Custody Model | Custodial (Bybit exchange) | Self-custody (Gnosis Safe L2) |
| Advertised Cashback | 1% base, no cap; 2–10% for VIPs (capped) | Up to 3% |
| Real Cashback ($2K/mo) | $20/mo (1% base, no cap) | $60/mo (3% × $2K, Core) |
| Cashback Token | BTC, USDT, USDC, or AVAX | USDC |
| Issuance Fee | Free (virtual) / $5 or 5 USDC (physical) | Free |
| Annual Fee | $0 | $0 |
| Conversion Fee | 0.9% | None |
| FX Fee | 0.5% (EEA) / 1–7% (other regions) | 0% (USD, EUR) / 1% (other) |
| Staking Required | No | No |
| Supported Crypto | 8 tokens | 15+ tokens across 6 chains |
| Countries | ~35 (EEA, CH, AU, LatAm) | 70+ (US, UK, EU, APAC, LatAm) |
| US / UK Available | No / No | Yes / Yes |
| Mobile Pay | Apple + Google Pay (EEA only) | Apple + Google Pay |
| Daily Spend Limit | €5,000 | $30K–$100K (tier-dependent) |
| Physical Card | Plastic ($5 or 5 USDC) | Plastic (Core), Metal (Luxe/Pinnacle) |
| Yield on Holdings | Variable per-asset APY via Auto-Earn (advertised up to 8%) | DeFi yield on collateral (variable) |
| Purchase Protection | Mastercard standard | $10,000 (Visa Signature) |
| Sweepbase Rating | 3.1 / 5 | 4.9 / 5 |
This used to be the section where Bybit fell apart. It is only half true now, because Bybit rebuilt the EEA reward model around a simple base rate:
Ether.fi Cash offers up to 3% cashback, paid in USDC, on a monthly spend ladder that steps down twice:
| Tier | 3% up to | 1% band | 0.5% above |
|---|---|---|---|
| Core | $2,000 | $2,001–$3,000 | $3,000 |
| Luxe | $10,000 | $10,001–$20,000 | $20,000 |
| Pinnacle | $50,000 | $50,001–$80,000 | $80,000 |
Tiers unlock through Membership Points, not fees: Luxe opens at 10,000 points and Pinnacle at 50,000, with an invite-only VIP tier above that. There is also a Business plan at a flat 1% with 0% FX on EUR. And one more ladder to know about: EUR spending earns 3% only up to €800 a month, then 1% up to €1,500, then 0.1% beyond. That is the price of the 0% EUR FX.
| Monthly Spend | Bybit EU Annual CB (1% base) | Ether.fi Annual CB (Core) | Difference |
|---|---|---|---|
| $500/mo | $60 (1% × $500 × 12) | $180 (3% × $500 × 12) | Ether.fi +$120/yr (3x) |
| $1,000/mo | $120 | $360 | Ether.fi +$240/yr (3x) |
| $2,000/mo | $240 | $720 | Ether.fi +$480/yr (3x) |
| $5,000/mo | $600 | $960 (3% on $2K + 1% on $1K + 0.5% on $2K); $1,800 on Luxe | Ether.fi +$360/yr (~1.6x on Core) |
On the EEA cards, Ether.fi pays roughly 3x Bybit's cashback up to the Core threshold, and about 1.6x for a $5,000/month spender who stays on Core. Notice the pattern flipped from the old situation: the gap now narrows as spend rises. Above $2,000 Ether.fi Core drops to 1%, matching Bybit's base rate, and past $3,000 it falls to 0.5%, below it. Big spenders can restore the 3x gap by moving up to Luxe ($10K at 3%) or Pinnacle ($50K), which takes Membership Points rather than money. EUR budgets follow the same shape on a lower ladder, so a €2,000/month spender also lands near 1.6x.
| Fee Type | Bybit Card | Ether.fi Cash |
|---|---|---|
| Card Issuance | Free (virtual) / $5 or 5 USDC (physical) | Free (all tiers) |
| Annual Fee | $0 | $0 |
| Crypto Conversion | 0.9% (min €1) | None (borrow model) |
| FX Fee (EEA) | 0.5% | 0% (USD, EUR) / 1% (other) |
| FX Fee (US domestic) | N/A (not available) | 0% |
| Total Cost per EEA Tx | ~1.4% (0.9% + 0.5%) | 1% |
| Borrow APY | N/A | ~4% on borrowed amount |
| Free ATM | €100/mo (EEA) | $250/day (2% fee) |
| ATM Over Limit | 2% | 2% |
| No-Fee Funding | Internal Bybit transfer | Solana USDC, Tron USDT (1:1) |
For EEA users, Bybit's total cost per transaction is ~1.4% (0.9% conversion + 0.5% FX), partly offset by the flat 1% cashback. Ether.fi charges 0% FX on USD and EUR purchases and 1% on other currencies. The ~4% APY borrow cost applies only in Borrow Mode, on the outstanding balance; Direct Pay Mode debits your vault stablecoins directly and carries no borrow cost at all. Users who carry large borrowed balances over time will feel the 4%, though the 3% cashback and DeFi yield on collateral typically offset it.

Custody model is the single biggest difference between these two cards:
After FTX, Celsius, BlockFi, and other custodial collapses, self-custody has become a risk management question, not just a preference. Ether.fi Cash is one of the only cards in the world that lets you spend without giving up custody of your crypto. For more on this topic, see our Self-Custody vs Custodial guide.
| Region | Bybit Card | Ether.fi Cash |
|---|---|---|
| United States | Not available | Available (excl. ~20 states) |
| United Kingdom | Not available | Available |
| Europe (EEA) | 27 countries | Most EU (excl. NL, FI, EE) |
| Switzerland | Available | Available |
| Canada | Not available | Available |
| Australia | Available | Available |
| Latin America | AR, BR, MX | Most countries |
| Asia-Pacific | Limited (AIFC, Taiwan) | HK, SG, KR, TW, and more |
| Middle East | Not available | UAE, Saudi Arabia |
| Total Countries | ~35 | 70+ |
Ether.fi Cash has twice the geographic coverage of Bybit and, more importantly, covers the two largest crypto card markets (US and UK) where Bybit is absent. For region-specific guides: USA | UK | Germany
| Perk | Bybit Card | Ether.fi Cash |
|---|---|---|
| Airport Lounges | 250+ lounges | No (Visa Signature benefits only) |
| Subscription Promo | 100% back on subscriptions, up to €50 in the first month (welcome offer) | No |
| Purchase Protection | Mastercard standard | $10,000 (Visa Signature) |
| Yield on Holdings | Variable per-asset APY via Auto-Earn (advertised up to 8%) | DeFi yield on collateral (variable, often 3–8%+) |
| Metal Card | No (plastic only) | Yes (purple metal Luxe, black metal Pinnacle) |
| Auto-Pay with Yield | No | Yes (yield pays off borrowed balance) |
| Daily Spending Limit | €5,000 (~$5,400) | $30K–$100K (tier-dependent) |
Bybit has an edge on lounges, and new cardholders get their subscription spend refunded in month one (100% back, capped at €50; Bybit's detailed help article on ongoing streaming perks is no longer live, so we only credit the welcome offer here). Ether.fi offers Visa Signature benefits ($10,000 purchase protection, extended warranty), metal cards, and far higher daily spending limits without any VIP requirement.
Bybit is a centralised exchange with no DeFi integration at all. Ether.fi Cash is built directly on DeFi infrastructure, and this creates a fundamental gap:
| DeFi Feature | Bybit Card | Ether.fi Cash |
|---|---|---|
| Spending Model | Sell crypto → spend fiat | Direct Pay debit from vault, or borrow against collateral |
| Collateral Yield | Auto-Earn variable APY (CEX product) | DeFi yield (staking, LP, restaking) |
| Yield Pays Bills | No | Yes (auto-repay borrowed balance) |
| Multi-Chain | No (Bybit exchange only) | 6 chains (Ethereum, Base, Arbitrum, Scroll, Solana, Tron) |
| Supported Assets | 8 | 15+ (incl. weETH, LiquidETH, eBTC) |
| No-Fee Funding | Internal transfer only | Solana USDC & Tron USDT (1:1, zero fee) |
| Composability | None | Full DeFi composability via Gnosis Safe |
The borrow-to-spend option is the main reason to pick Ether.fi. Instead of selling your ETH to load a card (triggering taxes and losing upside), Borrow Mode lets you borrow against it at ~4% APY while the collateral keeps earning yield, which can auto-repay your balance. If ETH appreciates 20% in a year, you benefit from the full upside while spending on your card. If you would rather not run a loan, Direct Pay Mode deducts purchases straight from the USDC or LiquidUSD balance in your vault, the two assets ether.fi names without ranking them. Either way the assets sit in your own Gnosis Safe. With Bybit, you sell the crypto and lose it forever.
The two cards handle taxes very differently:
| Tax Event | Bybit Card | Ether.fi Cash |
|---|---|---|
| Spending Crypto | Taxable disposal (capital gains/losses) | Borrowing, generally not a taxable event * |
| Each Purchase | Requires cost basis tracking | No disposal = no tracking needed * |
| Cashback Received | May be taxable income | USDC cashback, taxable as income |
| Collateral Yield | Interest income (Auto-Earn) | DeFi yield, varies by jurisdiction |
Ether.fi's borrow-to-spend model is a potential tax advantage in jurisdictions where borrowing is not treated as a disposal (including the US and UK under current guidance). This means you can spend without triggering capital gains events, which matters a lot for long-term holders sitting on large unrealised gains. The deferral only applies in Borrow Mode; Direct Pay Mode spends stablecoins out of your vault, so there is no loan involved. Bybit Card, like most custodial cards, requires you to sell crypto at each purchase, creating a taxable event every time.
Bybit Card has a real audience now: EEA users who keep funds on Bybit and want a simple 1% base card with no cap to think about, plus lounge access and VIP upside for heavy traders. For users in the US or UK, and for anyone who values self-custody, higher cashback, or DeFi integration, Ether.fi Cash is the better card.
The choice between these two comes down to philosophy: Bybit Card is custodial simplicity, Ether.fi Cash is self-custody with DeFi integration. Neither is universally better. If you hold most of your crypto on Bybit already, the card is a natural extension. If you're a DeFi user who wants to spend from yield positions without surrendering custody, Ether.fi Cash is built exactly for that.
