ether.fi Cash
A genuinely different architecture: keep full self-custody of 250+ assets and spend through a credit line instead of selling - with tiered memberships, travel cashback and premium Visa perks. The risks are equally clear: borrowing costs, portfolio volatility/liquidation risk, and a protection program that was still 'not yet live' at review time.
Krak Card (Kraken)
Kraken's consumer debit card: hold BTC (and 600+ other assets) in the Krak account and spend via an editable Spend Order that auto-converts at authorization on the Mastercard rate - no markup, no monthly fee, free plastic, metal for 50k balances, instant tiered cashback up to 2% in fiat or sats. Costs hide in the variable conversion spread, the default Rewards tier earns nothing, and spend/ATM limits are not published.
