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.
Revolut
The mainstream choice if you want crypto spend inside a full banking app - regulated, mature, multi-plan - but it is a bank card with a crypto side-feature: auto-conversion spreads, plan-based crypto fees and taxable disposals at every payment are the trade-offs.
