I compared 6 crypto cards on the exact same purchase in Europe. Test #
5# 👇
Same store, same EUR 9.69, same minute. Here's the all-in cost after cashback:
-
@ether_fi : $10.72
-
@Plasma : $10.93
-
@Backpack : $11.07
-
@lava_xyz : $11.10
-
@jup_mobile : $11.22
-
@KASTxyz : $11.25
Same groceries, but a 5% gap between cheapest and priciest. FX spread, fees and cashback decide everything.
Etherfi wins again, best rate plus onchain cashback. KAST is the priciest for the second test in a row, worst FX and a low-value fee on top.
The wild part: all three newcomers ran cleaner rates than Plasma, but zero cashback. Plasma's 3% back still carried it to second.
Your custom matchups are next. Which combo should I run first?
