So you contribute to implement a Bitcoin Standard by having your money on a bank and pay with credit card?
Discussion
If it is only one entity (or very few) cashing in sats it is not Bitcoin standard. I would try to convince activities that sell what I am looking for to do that or I would look for someone who already does it. The truth is that centralization is convenient and you can see that in these things as well.
Yes, using https://www.xapobank.com/ for example you pay with dollar or bitcoin using card and receive sats as cashback.
