Plans & pricing
Strengths
- Genuine FDIC bank; credit line doubles automatically after 7 on-time payments; Trustpilot 4.5/5.
- No notable sovereignty advantage documented.
Weaknesses
- APR ~22.70% variable; $36/year fee; no rewards.
- Traditional credit card: not self-custody — the account requires full KYC, a credit check, and can be closed or reported to credit bureaus by the issuer.
- Full KYC required: verified identity, zero pseudonymity.
- Subject to regulation (FDIC (vera banca)): reporting to authorities and freezes on order.
Verdict
Reliable but costly: a genuine FDIC bank (also Utah DFI-regulated) that automatically doubles the line after 7 on-time payments, with a good 4.5/5 Trustpilot and a $36 first-year fee (then $3/month). What keeps the score at tier B is the high APR (about 22.70% variable on the secured card) and the complete absence of rewards, which trim the overall value.
Here it counts for little precisely for what is a virtue elsewhere: being a full-KYC FDIC bank means maximum reliance on the intermediary, total custody and no on-chain privacy. US-only and with no crypto-native trait, the verdict on this lens is low.
