That partially explains how they can offer 4% rewards on a debit card.

That, and the 4% reward is in Stellar Lumens, not cashback.

cool. thats pretty interesting. I should read more about this. I wonder how long they'll be able to do it during a sideways or bear market.

That is so high. Are there any similar cards with lower fees?

"Hold", it will be soon available (https://utrust.com/hold/).

It's powered by Utrust which doesn't add any fee (only the seller gets a fee: 1% of the selling price). They just actually just introduced what they called reverse stacking : If you stack 1000 utk, you can get the 1% fee payed by the seller.

I am not sure about how much fees Visa will add from their part of the currency transfer. But I guess these fees will stay the same no matter which project you use as long as Visa is part of the payment solution.

https://foldapp.com/card/ is another option. Biggest different is that it spends USD directly and earns Bitcoin rather than spending cryptocurrencies.

Wirex

2.49% does not apply if USDC -- a dollar-pegged stablecoin -- is used as the payment method.
