Ether.fi Cash Card is the better card here. With self-custody, your crypto stays in your wallet until you actually spend it, unlike KAST where the issuer holds your funds. Ether.fi Cash also lets you earn yield on your deposits, something KAST doesn't offer. Zero fixed costs give Ether.fi Cash a cost advantage from day one. It works with Apple Pay and Google Pay, which is useful if you pay by phone. However, KAST may be better if you need something it does better.
In short: Ether.fi Cash Card (4.9/5) is the stronger option for most people compared to KAST Card (3.9/5).
