Goblin Card
The strongest physical no-KYC card pitch: a real Mastercard with ATM access, 0% FX and 0% ATM fees, XMR deposits and privacy-preserving support channels. The trade-offs are a $350 entry price, 3.5-4% deposit fees and an unlicensed custodial balance - treat it as a privacy tool, not a bank account.
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.
