Why 10% Crypto Cashback Usually Isn't 10%
Crypto card ads love big numbers: "up to 8% back", "10% cashback". Those rates do exist, but almost nobody earns them. The number you'll actually see is usually somewhere between 0% and 3%, and sometimes the card costs you more than it pays back.
Short version: the headline rate is the best tier, not the normal one. Before you choose a card, check five things: what the top tier requires, the monthly cap, the plan fee, what currency the reward is paid in, and what spending is excluded.
1. The top rate belongs to the top tier
Most exchange cards use tiers. You climb them by locking up the exchange's own token, keeping a large balance, or reaching a VIP trading level. The "up to" rate in the ad is the rate of the very last tier.
Crypto.com's card is a clear, published example. On its own card page:
| Tier | What it takes | Everyday cashback |
|---|---|---|
| Midnight Blue | Free | 0% |
| Ruby Steel | €3.99/month, or €450 of CRO locked for 12 months | 1.5% (on up to $750/month) |
| Jade Green / Royal Indigo | €24.99/month, or €4,500 of CRO locked | 2.5% (on up to $1,500/month) |
| Icy White / Rose Gold | €45,000 of CRO locked | 3.5% (on up to $3,000/month) |
| Obsidian | €450,000 of CRO locked | 4.5% (on up to $5,000/month) |
The free card pays nothing on everyday spending. To get the top rate you'd need almost half a million euros sitting in one exchange token for a year.
2. Monthly caps cut the rate as you spend more
Even when you qualify for a tier, the reward is usually capped. A cap can apply to how much spending earns the rate, or to how much reward you can receive in a month.
Bybit's card is an example of a reward cap. Its help centre lists a monthly reward cap of $5 on the base tier. At 2%, that's used up after $250 of spending. Spend $1,000 that month and you still get $5, so your real rate is 0.5%, not 2%.
That's why our cashback calculator asks how much you spend. The same card can be the best choice at $300 a month and a poor one at $3,000.
3. Plan fees have to be earned back first
Some cards replace the staking requirement with a subscription. That's often the more sensible route, but the fee comes off your rewards before you've earned anything.
For example, a plan costing about $4.60 a month that pays 1.5% only breaks even at around $307 of monthly spending. Spend less than that and the card costs you money.
The calculator on the home page subtracts plan fees automatically and picks the cheapest plan that pays the most at your spending level.
4. The reward is often paid in a volatile token
Many cards pay cashback in their own token (CRO, BNB, BGB, NEXO, WXT and others) rather than in dollars or euros. If that token falls 30% before you sell, your 2% cashback is now worth 1.4%.
The same risk applies, much more heavily, to any tokens you lock to unlock a higher tier. A 3% reward on spending won't make up for a big drop in the value of the tokens you had to stake to get it.
Cards that pay in a stablecoin, in bitcoin, or in a currency you choose avoid the first problem. They don't remove price risk entirely, but you're not tied to a token whose price depends on one company.
5. Not every purchase earns cashback
Common exclusions include:
- Topping up other wallets, gambling, money transfers and similar "cash-like" spending.
- Some bill payments, taxes and government fees.
- Spending above the cap, or after a promotional period ends.
If you pay with crypto, the card also converts it into local currency when you spend. That conversion often carries a spread or fee, which can quietly cancel out a 1% reward. Check the issuer's fees page before you assume the reward is pure profit.
A worked example
Imagine a card advertised at "up to 8%". You spend $1,000 a month and don't want to lock up any tokens.
- Without staking you're on the base tier, which pays 1%: $10.
- The base tier has a $5 monthly reward cap: $5.
- The reward is paid in the exchange's token, which drops 20% before you sell: $4.
The real return is 0.4%, twenty times less than the ad suggests. Some cards look much better on the same test. A plain 1.5% to 3% card with a reasonable cap, no fee and no staking often beats an "up to 10%" card for normal spending.
How to compare cards honestly
- Ignore the "up to" figure and find the rate for the tier you'll realistically reach.
- Check the monthly cap and work out your effective rate at your own spending.
- Subtract any plan or card fee.
- Prefer rewards paid in stablecoins, BTC or your chosen asset over a single exchange token.
- Read the exclusions and conversion fees.
That's exactly how the BestCryptoCash list is built: the big green number on each card is the rate you get without staking, and the calculator does the cap and fee maths for you.
Rewards on crypto cards may be taxable where you live, and selling the reward later can count as a disposal. Check your local rules. Nothing here is financial or tax advice.
