AdvCash
A veteran offshore e-wallet with usable-but-fragile card rails: availability has opened and closed with issuer changes for a decade. Watch listing - usable for its niche, with the structural issuer fragility priced in.
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.
