Cards That Pay Cashback in Bitcoin

Earning bitcoin through a card is interchange arbitrage: the merchant's network fee funds a rebate, and the operator pays it to you in sats instead of points. That mechanism caps what any card can honestly pay - which is why every program on this page differentiates with gates, not rates: monthly spend caps, balance ladders, membership tiers, boost rotations. Reading those gates is the whole skill. The card that "pays the most" on the landing page is routinely the one that pays you nothing at your actual numbers.

9 live cards pay rewards in bitcoin, the median documented rate sits near ~1.75%. Their earn engines differ in one structural way: what unlocks the rate. Spend volume, assets held, or a paid tier - and the tax and custody consequences follow the gate, not the headline.

The rate keys, ranked by how they gate

Flat and uncapped is the rarest and cleanest shape: Fold pays 0.25% on all eligible purchases with no cap and no Reserve requirement, in BTC, subject to a 30-day pending period [1]. No conditions to model, no cliff to fall off - the rate you see is the rate a $100 month and a $10,000 month both earn.

Monthly spend caps concentrate value at the bottom: Gemini pays 4% on the first $300/month and 1% after [3]; Crypto.com's tiers pay up to 6% on the first $10,000 and 2% beyond [6]. This shape favors small budgets and punishes the exact users the headline attracts - the second dollar earns a quarter of the first.

Balance ladders tie earn to assets on platform: Fold's boosts start at a $15,000 Reserve and top out at 3% for $100,000 [1]; Krak's five tiers run from 0% (Starter) to 2% at a 50,000 GBP/EUR 30-day average [4]; Nexo requires $5,000+ and a Gold-or-better loyalty tier before Credit Mode pays anything at all [5]. These are wealth products wearing card clothing - the earn is a loyalty dividend on custody you already handed over.

What the rewards are worth - and what they cost

Three deductions sit between the headline and your wallet, and only the first is visible:

• The cap. Nexo's monthly caps are the starkest published case: $200/month maximum at Platinum, $50 at Base [5] - at the $200 cap, even 2% earn implies $10,000 of monthly spend, so the effective rate for a normal user is the cap, not the rate. Gemini's $300 band, Fold's $5,000 boost cap [1] and ether.fi's tier ladders [see the ether.fi review] all work the same direction: the marginal rate on your last dollar is lower than the first.
• The spread. Cashback is paid in BTC bought at the operator's conversion rate; the spread on that conversion is deducted invisibly. A 2% earn with a 1.5% effective spread is a 0.5% earn - the method for measuring it is in the spread guide.
• The tax. In the US, rewards in crypto are income at receipt and a disposal when spent [7]; HMRC's pooling rules mirror the structure for UK users [8]. Bitcoin-back multiplies the bookkeeping, not just the yield - per-transaction lots, each needing a cost basis.

The realistic yield ceiling

Stack the documented best case: a user spending $2,000/month across the strongest documented structures earns on the order of $40-80/month in BTC before costs - meaningful as a DCA automation, not as income. That is why this page treats earn cards as an accumulation instrument: the value is the forced, fee-native bitcoin buying on spending you were doing anyway. The moment a subscription, a lockup or an altcoin payout enters the picture (4 of the cards here publish a cap), the comparison belongs in a different frame - the money guide on spending vs earning draws that line.

Field notes

• Elect BTC, not the native token. Where the operator allows the choice (Crypto.com [6], Nexo [5], Krak [4]), the BTC payout is the honest one - the token payout is a higher number with a drawdown attached, not a gift.
• Match the gate to your curve. Spend under $500/month favors a capped high rate (Gemini [3]); $2,000+ favors ladder bottoms (ether.fi Core, 3% to $2k [see the ether.fi review]); irregular spend favors the flat 0.25% (Fold [1]).
• Check the pending period before the first bill cycle. Fold's 30 days [1] means a month of rewards is a claim. If the operator changes terms mid-pending, you inherit the change.
• Stack spillover, don't chase boosts. Two complementary cards - one capped high-rate, one flat uncapped - beat any single card's blended rate. The stack builder prices the pair.
• Automate the exit. Rewards that sit on the operator's ledger are a claim. Whatever your self-custody cadence is for exchange balances, apply it to rewards too - the custody guide sets the pattern.

Warnings and hard limits

• Headline rates are tier ads. Gemini's 4% is a $300 band [3]; Crypto.com's 6% is a $10,000 monthly band on its top membership tier [6]; Nexo's 2% requires $5,000+ in assets and Platinum standing [5]. The base rate is the product; the headline is the hook.
• Reward rates have a history of moving. Fold replaced its entire program structure in September 2026 - 0.5% gated became 0.25% uncapped, with a published changelog [1]. Most operators do not publish one. Re-read the rewards terms quarterly; the changes feed tracks what we catch.
• Token payouts are altcoin positions. A 2% NEXO payout [5] that halves in a month earned you 1%. If you would not hold the token, you are not earning 2% - you are earning 2% minus your exit.
• Cash advances are not earnings. The credit products in this population charge $10-or-3-5% cash advance fees with APRs from 29.5% to 32.5% accruing from day one [3][6]. Treat the ATM as outside the earn lane entirely.

The cashback hub runs the same population through the net-yield arithmetic; the spend hub covers the flow that feeds it. Earn on documented terms, elect the payout you would actually hold, and the earn lane is a quiet DCA riding your normal spending.
