Fold Bitcoin Debit Card
The reference bitcoin-back debit card in the US: sats on every swipe, FDIC pass-through on the dollar balance via Sutton Bank, BitGo custody and a Nasdaq-listed parent. Rewards are variable-rate spins rather than a fixed percentage - treat the sats as a bonus, not a yield.
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.
