Head to head
ether.fi Cash vs OKX Card
The two top cards on this site, and level at €1,500 a month in the eurozone. ether.fi pays 3%, but on euro purchases only up to about €700 a month, and in its own ETHFI token; OKX pays a flat 2% in the USDG stablecoin, up to €50 a month. ether.fi wins for smaller spenders and outside the euro, OKX for bigger euro spenders who want a stable reward.

Where the difference comes from
The rates work differently. On its free Core level ether.fi pays 3% on the first $2,000 of spending each month, then 1% on the next $1,000 and 0.5% beyond, but euro purchases follow a lower ladder on the same monthly total: 3% only on the first $800 (about €700), 1% up to $1,500 and 0.1% above. The cashback arrives in ETHFI after a 7-day lock, so its value moves with the token. OKX pays 2% on purchases funded with USDG, paid in USDG within 72 hours, and stops at €50 a month, which it reaches at €2,500 of spending. Funding the OKX card with USDC earns nothing.
In the eurozone, ether.fi is ahead for smaller spenders, €177 against €114 a year at €500 a month, and the two are level at €1,500 (€342 each). Above that OKX pulls away, €564 against €372 at €3,000, because ether.fi’s euro rate drops to 0.1%. Romania is different: lei purchases follow ether.fi’s higher dollar ladder, so ether.fi leads up to about €2,300 a month (€432 against €342 at €1,500) despite its 0.5% fee on lei, and OKX edges ahead only at €3,000 (€564 against €547). Heavy euro spenders can change the picture by upgrading ether.fi: its $199-a-year Luxe level lifts the euro cap to $3,000, worth about €819 a year at €3,000 a month in Germany. OKX’s higher rates need VIP status from trading.
Beyond the rate, they are opposites. ether.fi is a self-custodial credit card: your assets stay in your own vault, you can borrow against ETH instead of selling it, and the card is issued by a third party, while ether.fi itself holds no financial licence. OKX is a custodial account run by a Maltese MiCA-licensed operator, debit only, with no FX fee and at most 0.1% conversion. ether.fi is not available in the Netherlands, Finland or Estonia but serves the UK and Switzerland; OKX covers the EU and Norway but not the UK or Switzerland.
Choose ether.fi if…
you hold ETH and want to borrow against it, spend less than about €1,500 a month in euros, or live in Romania, Hungary, Poland, Norway, Switzerland or the UK.
Choose OKX if…
you spend more than about €1,500 a month mostly in euros, want cashback in a stablecoin, or prefer a MiCA-licensed exchange.
