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

B D ★ 3.8/5 ★ 1.4/5 Estimated net annual cost: €36/year

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.
