Every card in this category charges a spread to convert crypto into fiat at the point of sale. Fold does not, because you are not spending crypto — you spend dollars from a normal debit balance and receive bitcoin as a reward.
Why that structure is better than it sounds
The conversion spread is typically the largest cost of using a crypto card, and it applies to every purchase. Removing it entirely, while still accumulating bitcoin, produces better economics than most cashback tiers achieve after their staking requirements and conversion costs are counted.
Rewards
Rates vary by merchant and promotion rather than following a fixed published schedule, with boosted rates on specific retailers and gift card purchases. That variability makes the effective rate harder to predict and, for users who shop where the boosts apply, quite generous.
Limitations
United States only, tied to a conventional banking relationship, and dependent on promotional structures that can change. It also does nothing for anyone wanting to spend an existing crypto balance, which is the actual use case for most cards in this list.
Who should use it
US users who want to accumulate bitcoin through everyday spending rather than spend crypto they already hold. It is a different product from the rest of this category, and for its purpose it is well built.
