It requires income ≥€11,000, charges a 2.5% FX fee and carries the lower acceptance of the Amex network versus Visa/Mastercard.

Verdict

B D ★ 3.5/5 ★ 1.2/5

The Blue Card is the most accessible Amex credit card: free the first year, €35/year after, with a flat 1% cashback that for the average spender easily repays the fee. The limits are the 2.5% FX fee, the cashback halved to 0.5% if you never pay the fee, and the lower acceptance of the Amex network. Overall a balanced choice for those wanting simple low-cost cashback, with an above-average rating.

A credit card is a credit line, not custody of funds: there is neither self-custody nor a user balance here. It remains, however, a fully tracked and censorable instrument — full KYC, an American Express (US group) issuer that profiles transactions and can suspend the line. On the sovereignty lens it is the opposite of trustless tools: no anonymity, no censorship resistance.
