Xapo Bank
The only true bank in the comparison: a Gibraltar credit institution with deposit-guaranteed USD, savings interest paid daily in BTC and worldwide card spending with no FX fees. The $1,000/year membership makes it a wealth product, not a spending card - it pays off for balances where the 3.35% yield outruns the fee.
KAST
The most complete stablecoin-spending account on the market: US/EU virtual bank accounts from anywhere, Visa Platinum cards with real 1.5% USD cashback on the free tier, instant cashback and no spending caps. Full KYC and a young operator are the trade-offs; the paid tiers only make sense for heavy spenders.
