whats your strategy? if you only want to spend fiat then you can use any card...
Any card does not return me 1% in crypto tokens

My strategy is based on automatic recharges. I shop with fiat
or buy crypto with the preloaded balance.
However, your example has reminded me of an idea that some banks already do: Rounding.
You buy something for 27, the bank charges you 30 and the rest sends it to a different address of your property. A kind of self-saving.
Replace "send to another address" to "buy XX crypto" and there you have a great suggestion

yeah ur right, 2gehter could implement this. auto-round-up-2-crypto
great idea

i guess people would use it. you could choose at what "," you want to round up.
27,67
rounded to:
27,70 or
28,00 or
30,00
.... automatic recharge, hm.. i didnt intend to use it. but ill take a closer look at it and see what it can do for me.
usually i got enough funds on the card.
