That “5% cashback” is doing a lot of work
Crypto card rewards can look like one clean number. In practice, that number can sit behind a paid plan, a token balance, a spend threshold, a merchant category or a cap. Here is how to find the rate you can actually use.
Put two cards side by side. One advertises “up to 5%”. The other pays 2% on the tier you can join today. The first card is not automatically better. Its 5% may cost money to unlock, stop after a small amount of spend, arrive in a volatile token, or apply only in one narrow category.
The useful question is not “Which card has the biggest number?” It is “What do I receive on my normal purchases, after conditions and costs?”
01 — Start here
Max cashback is a ceiling, not your starting rate
“Up to” is useful when it describes the upper edge of a programme. It becomes misleading when that edge is read as the everyday rate. We separate the accessible rate from the headline maximum because the gap between them can be an important part of the offer.
plan · stake · status · spend
eligible purchases × reward band
cash · stablecoin · token · points
plan · FX · top-up · conversion
What remains is your usable reward — not the number in the ad.
How we use the catalog here
We use reviewed cards as examples of different reward mechanics, not as a market survey. The goal is to show what to check on any card without pretending that our current catalog represents the whole market.
02 — Read the gate
“Conditional” does not always mean “paid tier”
A subscription is the easiest gate to spot, but it is only one version. A free plan can still ask for a large balance, a token lock, a certain monthly spend or a special merchant category. Each condition has a different cost and a different kind of risk.
A paid plan
The extra percentage may sit inside a monthly or annual membership. The rate lift has to earn back that fee before it creates value.
Token or account status
A card may ask you to hold or lock a token, maintain a portfolio balance, collect points or reach VIP status.
Spend or category rules
Some boosts unlock after a spend threshold or apply only to selected merchants. That is not the same as a general cashback rate.
03 — Do the small calculation
The cap can matter more than the percentage
A reward rate applies only to eligible spend. If the programme stops paying after a threshold, your effective rate falls as you keep using the card. This is why the cap belongs next to the percentage, not in a footnote three screens away.
Imagine 3% applies to the first $1,000 of eligible monthly spend. That produces $30. Spend another $1,000 after the reward band ends and your effective rate across the full $2,000 is 1.5%, before any fees. This is an illustration, not a claim about a particular card.
A different pattern
Same top rate, wider band: ether.fi
KAST’s higher-rate tiers also carry higher annual plan fees: Standard lists 1.5% — no annual plan fee; Premium lists 2% — $1,000/year plan; and Private lists 3% — $10,000/year plan. Those fees pay for the whole membership, not cashback alone, so the extra reward has to be weighed against the full plan cost.
Ether.fi is a useful counterexample to the assumption that a higher tier must raise the headline percentage. Core, Luxe and Pinnacle keep the top USD band at 3%, while extending that band through $2.0K, $10.0K and $50.0K of monthly spend respectively. After each threshold, the documented USD ladder steps down to 1% and then 0.5%.
Ether.fi lists no annual plan fee for these three levels. Access is status-based instead: Core — All Club members; Luxe — 10K Membership points/mo or 15K ETHFI; and Pinnacle — 50K Membership points/mo or 100K ETHFI.

04 — Follow the reward
Cashback is only as simple as the asset you receive
“Cashback” may mean fiat, a stablecoin, BTC, a project token or internal points. Those are not interchangeable. Check whether the amount is fixed in dollar terms when earned, whether it can be spent immediately, and whether converting it creates another fee or taxable event in your jurisdiction.
Token rewards can rise after you receive them, but they can also fall. That upside is not extra cashback; it is market exposure layered on top of the card reward.
05 — Subtract the boring bits
Fees do not care how exciting the cashback looks
A 3% reward on $1,000 is $30. A 1.5% FX cost on the same spend is $15 before plan fees, top-up fees, conversion spreads or token price changes. The reward can still be worthwhile, but only after both sides of the equation are visible.
Net value = usable rewards − plan cost − transaction costs − conversion friction
The companion FX and conversion guide maps those cost layers from funding asset to checkout currency.
Real cards, real trade-offs
Three ways the headline can change meaning
These are examples from reviewed profiles in our catalog, not a ranking. Each block reuses the same approved card data as the detail page, so a data update can flow into both places.
KAST and Bybit show two different ways a higher rate can be gated. Ether.fi shows why the percentage and the reward band need to be separate fields.

- 3
How much spend earns rewards before the daily, monthly or annual cap applies?
- 4
What asset or points balance will I actually receive?
- 5
Can FX, conversion, top-up or plan fees erase the reward?

FAQ
Quick answers
Is the card with the highest max cashback usually best?
No. The accessible rate, cap, eligibility rules, reward asset and total card costs can reverse the result.
Does a free tier mean the cashback is ungated?
No. A $0 subscription can still require token holdings, account status, spend thresholds or selected categories.
Why does your catalog show unknowns?
Because an undisclosed cap or fee can change the decision. We do not turn missing data into a positive assumption.
